Spirillum minus, the other etiologic agent of rat bite fever, was discovered during the 19th century and initially named Spirocheta morsus muris or Sporozoa muris. La fièvre par morsure de rat à spirilles (sodoku) est provoquée par Spirillum minus. Penicillin, when given in rather high dosages seemed to be more reliable. Two well-documented cases of IE due to Chlamydia trachomatis have been reported.486 Microimmunofluorescence tests are necessary for a diagnosis. This disease is most commonly found in Asia. The healed bite wound may reactivate when fever develops. S. minus can be directly visualized in blood and infected tissues using Giemsa stain, Wright stain, or darkfield microscopy. Description and Significance. Pediatric Clin N Amer. Many, including rabbits, carry Pasteurella multocida as part of their mouth flora. The flagella can be stained with silver impregnation methods (e.g., Fontana-Tribondeau). Treatment is with penicillin, tetracycline, or doxycycline. or intravenously every 6 hours or doxycycline 100 mg p.o. Rat-bite fever is caused by either Streptobacillus moniliformis or Spirillum minus. Blood smears from all but one of the untreated mice remained positive for S. minus for the 30-day observation period. Effects of Rat-Bite fever 11. Symptoms of rat bite fever depend on the microbial etiology and route of infection. Ingestion of the organism does not cause disease. Cleri DJ, Ricketti AJ, Vernaleo JR. Fever of unknown origin due to zoonoses. or intravenously every 12 hours. 鼠毒症(Sodoku)是一種以動物為傳染媒介的細菌感染症。 致病的細菌 Spirillum minus ( 英语 : Spirillum minus ) 是一種革蘭氏陰性桿菌,屬於一種 鼠咬熱 ( 英语 : rat-bite fever ) (rat-bite fever, RBF)。. Spirillum minus is the principal cause of rat bite fever in the Eastern hemisphere, but only rarely causes disease in the United States. The organism, first described by Dr. Henry Van Dyke Carter in 1887, was previously known as Spirocheta morus muris, Sporozoa muris, Spirochaeta laverani, Spironema minor, Leptospira morsus minor, Spirochaeta muris and Spirochaeta petit (8). 18. Elles ont une forme de spirale et sont mobiles grâce à des flagelles à leurs pôles. [PubMed]. Spirillum, genus of spiral-shaped bacteria of the family Spirillaceae, aquatic except for one species (S. Minus) that causes a type of rat-bite fever in man. Symptoms of RBF associated with Spirillum minus may include an unsteady fever, swelling or ulcer like formation at the site of the bite, swollen lymph nodes and rash that can appear at wound site or cover the entire body. Endpoints for monitoring therapy have not been established. 4. S. minus has not been cultivated on laboratory media. Laboratory studies reveal a leukocytosis and up to 50% of patients have a false-positive serologic test for syphilis (9). Mandell, Douglass, and Bennett’s Principles and Practice of Infectious Diseases. Nasopharyngeal carriage rates of 50–100% in wild rats have also been reported (Gaastra et al., 2009).

This most commonly occurs through a bite, yet … 5. The 100% preventive dose (PD100) for penicillin was 1000 units, while the PD100 for tetracycline, oxytetracycline, chloramphenicol, and streptomycin was 100 μg, 100 μg, >200 μg, and >100 μg respectively. A violaceous maculopapular rash on palms and soles, very similar to the one seen in syphilis, is a common feature. Rat-bite fever in Montana. Describe the optimal conditions for culturing … During the succeeding four weeks Spirillum minus was easily demonstrated in the blood of all 4 mice. Copyright © 2021 Elsevier B.V. or its licensors or contributors. 1958;11:407-13. 16. The exclusion of infected rodents from production colonies of commercial suppliers has been largely successful in eliminating the disease in the laboratory (Committee on Occupational Safety and Health in Research Animal Facilities, 1997). Small mammal pets include mice, rats, hamsters, gerbils, guinea pigs and rabbits. As Spirillum species generally obligately microaerophiles and are Penicillin, when given in rather high dosages seemed to be more reliable. Sprillum endocarditis. Generally, the bite wound heals during the 1 to 3 week incubation period. Spirillum minus is found in a wide variety of tissues and fluids of infected rodents including blood, peritoneal fluid, conjunctival fluid, muscle, tongue, and lung tissues (17). 5. • A spirillum (plural, spirilla) is a thick, rigid, spiral organism that can cause rat bite fever, an uncommon but worldwide condition caused by rodent bites. IE due to C. burnetii (the cause of Q fever) is well documented in the United Kingdom, the United States, Canada, France, the Middle East, and Australia.478-480 Ten cases of Q fever IE were recognized in four Dublin teaching hospitals during a period of 3 years.479 Q fever usually is a self-limited respiratory illness caused by the inhalation of infected aerosols.481 The first IE cases were reported in 1959. Jarisch-Herxheimer reactions may occur during the initial stages of therapy (15). Musculoskeletal symptoms (arthralgia or myalgia) are less common in infections with S. minus than in streptobacillary rat-bite fever. The term spirillum is used generally for any of the corkscrew-like species. Focal abscesses and endocarditis may occur. Ann Soc Belges Med Trop Parasitol Mycol. Spirrilum is a genus of bacteria pathogenic mostly to rats , guinea pigs and mice. Bacteria from this genus have unusual … Rat-bite fever due to S. minus (also known as spirillary rat-bite fever and sodoku) is seen worldwide but is most common in Asia.18 A rash with reddish or purplish plaques accompanies the fever. …infection caused by the bacterium Spirillum minus (also called Spirillum minor) and transmitted to humans by the bite of an infected rat. Tani and Takano reported treating experimentally infected mice with a variety of antimicrobial agents to determine the dosage required to prevent transmission of disease through transfusion (19). Chapter 39 Streptobacillus moniliformis and Spirillum minus Objectives 1. If the bite wound initially begins to heal, inflammation recurs at the site after 4 to 28 (usually > 10) days, accompanied by a relapsing fever and regional lymphadenitis. A diagnosis can be established with the demonstration of complement-fixing antibodies. Evidence at present indicates that two different infectious agents may produce the disease known as rat bite fever: Spirillum minus and Streptobacillus moniliformis. 1965;116:39-54. Cook GC. Ratbite fever. Like the other Spirilla bacteria, Spirillum minus are characterized by a spiral shape. It also infects cats and other carnivores that feed on infected rodents (4). In: Hubbert WT, McCulloch WF, Schnurrenberger PR (eds). 1975;9:186-90. List the symptoms of rat-bite fever. Apresenta distribuição universal, sendo frequente na Ásia, especialmente no Japão e é rara nos Estados Unidos. Rat bite fever: three case reports and a literature review. [PubMed]. As compared to some of the other Spirilla, however, they tend … Treatment is with penicillin or tetracycline. The symptoms can present themselves anywhere between 1-3 weeks after contact with the bacteria. What disease does Spirillum bacteria cause? When left … Saunders, Philadelphia. The most serious complication is endocarditis which usually occurs in the setting of pre-existing valvular abnormality (20). The study evaluated 1135 heart valves that were analyzed for bacterial infection using conventional culture techniques, PCR amplification of the bacterial 16S rRNA gene, and subsequent sequencing. Most patients had preexisting heart disease, with a striking propensity for aortic valve involvement, and rapid valvular destruction leading to surgical intervention or death. James G. Fox, ... Harry Rozmiarek, in Laboratory Animal Medicine (Second Edition), 2002. A red-brown occasionally urticarial rash sometimes develops but is less … 12. Antonie van Leeuwenhoek, a Dutch scientist, known as the Father of Microbiology, is believed to be the first person to identify Spirillum species of bacteria in the 1670s. Spirillum minus rat-bite fever is also called sodoku: ‘so’ means rat and ‘doku’ means poison in Japanese.120 The initial lesion of the rat bite usually heals promptly. Infect Dis Clin N Am. Infection in humans results from exposure to the urine, feces or saliva of the rodent and may result in no symptoms, although a flu-like syndrome or meningitis may occur. Regional lymphadenitis is present in the majority of cases. The bite site may ulcerate and progress to a chancre-like lesion (4, 6). Most types of bacteria possess flagella, or whip-like appendages, that help them to move through solutions. n/a: Not transmitted from person to person. Although this disease is readily cured with antibiotics, untreated infections are sometimes fatal. Spirillum refers to a genus of Gram-negative bacteria in the family Spirillaceae. Immune complex–mediated glomerulonephritis develops in approximately 25% of cases.478,479,482 Histologically, C. burnetii IE is characterized by significant fibrosis and calcifications, slight inflammation and vascularization, and small or absent vegetations.272 The rickettsiae were shown histologically in the valve tissue in 62% of the cases, and the organism was isolated in 83%, although this poses a significant laboratory hazard.274 The diagnosis is best made serologically; a positive titer of antibody to the phase I antigen as measured by complement fixation or enzyme-linked immunosorbent assay indicates chronic infection, whereas a fourfold rise in titer of antibody to the phase II antigen is associated with active current infection. Both Streptobacillus moniliformis and Spirillum minus are … Diagnosis is clinical and confirmed by culture (of the streptobacillary form) and sometimes rising antibody titers. Rat-bite fever (Streptobacillus moniliformis disease, Spirillum minus disease) Standard. If the bite wound initially begins to heal, inflammation recurs at the site after 4 to 28 (usually > 10) days, accompanied by a relapsing fever and regional lymphadenitis. Two types of Gram-negative, facultatively anaerobic bacteria can cause the infection. Use Contact Precautions for a minimum of 48 hours after the resolution of symptoms or to control institutional outbreaks. No attempt at sequence analysis of the organism in body fluids has been reported. Freels LK, Elliott SP. All references are available online at www.expertconsult.com. J Pediatrics. Elles sont rencontrées dans les … A recent study from Germany involving heart valves reported that T. whipplei was the most common cause of culture-negative IE. Clin Microbiol Rev. Fachwörterbuch Medizin Englisch-Deutsch. A red-brown occasionally urticarial rash sometimes develops but is less … Spirillum, genus of spiral-shaped bacteria of the family Spirillaceae, aquatic except for one species (S. minus) that causes a type of rat-bite fever in man. Rats are frequently colonized by S. minus (2, 9) and infection in humans is usually acquired through the bite of a rat. Learn more here. No serologic test is available. Rat-bite fever is also contracted through contact with secretions of infected rats and less often through contact with other S. moniliformis and S. minus hosts, such as gerbils, mice and squirrels. If untreated, relapsing fever will develop. 1955;62:101–108. Endocarditis and Central Nervous System Infection. Five cases of IE due to Spirillum minor, a spirochete, have been reported. Other spirochaetal diseases (excluding Treponema spp and Leptospira spp. Rat bite fever. 101 Worldwide millions of people are bitten by animals each year. 21. No published studies indicate that specific underlying conditions predispose one to infection or complication due to S. minus or necessitate a change in treatment recommendations. The rat-bite wound usually first heals… Several cases of probable Chlamydia pneumoniae IE have been reported.487 IE due to Mycoplasma pneumoniae was proposed in one case report, but cultural confirmation was lacking.488, T. whipplei is the causative agent of Whipple's disease. Relapsing fever. The diagnosis requires highly specialized laboratories for confirmation. [PubMed]. The epidemiology of S. minus infection is similar to that of Streptobacillus moniliformis. Ann Trop Med Parasitol. Most cases have been associated with psittacine bird exposure; in one case, chlamydiae were found in the liver of the suspected budgerigar. Although its precise ecologic niche is unclear, there is increasing evidence to suggest that T. whipplei may be a component of the microbiota of the human respiratory tract, especially in patients with HIV. Pediatr. Robertson A. Observations on the causal organisms of rat bite fever in man. Infectious Disease Practice for Clinicians 2006;30:509–13. Rat bite fever is a human illness that can be caused by two different bacteria, Streptobacillus moniliformisand Spirillum minus. Treatment is with penicillin or Elliott SP. The organism was named S. minus in 1924 (14).The first case description of rat bite fever due to S. minus in the United States was described by Shattuck and Theiller in 1924 (16). 1979;26:377-413. Thijsen, in Infectious Diseases (Third Edition), 2010. Adams JM, Carpenter CM. Spirillum minus has been isolated from the oropharynx, blood, and exudates of up to 25% of wild rats. In the event of serious penicillin allergy, a tetracycline derivative should be employed in the treatment of S. minus infection. INTRODUCTION. Although the efficacy of prophylaxis is not proven, a prudent course-of-action would dictate administration of amoxacillin/clavulanate at a dosage of 500 mg p.o. Many are beneficial symbionts that populate the human gut, but others are familiar human pathogens. Rat-bite fever can be caused by 2 different bacteria, Streptobacillus moniliformis or Spirillum minus. Arch Intern Med. Disease• Spirillum minus and Streptobacillus moniliformis arespecies of Spirillum.• Spirillum minus cause rat-bite fever illness caused by bacteria transmitted Rat Bite by rodents, rats, in most cases, which is Fever ?? Standard. 179 This organism is widely distributed in nature, especially in fresh or salt water with organic debris. Tropical Medicine, 5th Edition. The prognosis with medical therapy alone is poor, and valve replacement often is necessary for a cure (see later discussion). 1945;69:215-220. Case 2.—M. Most types of bacteria possess flagella, or whip-like appendages, that help them to move through solutions. W.B. In Japan, the disease is known as sodoku (Gaastra et al., 2009). n/a: Not transmitted from person to person. The diagnosis of S. minus infection can be proven by recovery of organisms from mice or guinea pigs, 1 to 3 weeks after intraperitoneal inoculation of infectious material from the index patient. 20. passed from rodent to human via the rodents urine or mucous secretions. Roughgarden JW. THE causative organism of the disease known as rat-bite fever or sodoku was identified by Futaki and his associates1 in 1916. A means of propagation of the organism in laboratory media has not been established, nor are specific serologic tests available. Excellent response is expected with the use of procaine penicillin given intramuscularly (20,000–50,000 U/kg once daily), penicillin G given intravenously, or penicillin V given orally (1–2 g/day divided into 3 doses).29–31 Streptomycin and tetracycline are effective alternative agents. Rat-bite fevers. In contrast to S. moniliformis, S. minus has not been described to cause disease via oral ingestion. Half of patients infected by S minus have a positive serology for syphilis (4). 2. Most cases of C. burnetii IE are chronic, with a history of an influenza-like illness occurring 6 to 12 months previously. Ingestion of the organism does not cause disease. 3. Shattuck GC, Theiler M. Rat-Bite Disease in the United States with report of a case. Hier die Übersetzung Englisch ↔ Deutsch für spirillum nachschlagen! However, most authorities recommend treatment of 10 to 14 days. Sodoku. The organism was named S. minus in 1924 (14).The first case description of rat bite fever due to S. … Treatment consists of penicillin or tetracycline. Vance G. These bacteria are known for their elongated structure. A single case of IE due to the causative agent of murine typhus has been reported.263, Chlamydia psittaci, the agent of psittacosis, has been implicated in at least 10 well-documented cases of IE.485 This organism also may cause myocarditis or pericarditis. In: Bennett JE, Dolin R, Blaser MJ(eds). This zoonotic illness can occur after being in contact with a rodent carrying either Streptobacillus moniliformis or Spirillum minus bacteria. At the site of the bite, the wound reactivates and an eschar develops. Data are derived from anecdotal reports of treatment of single or small groups of patients. Disease caused by Spirillum minus is known as sodoku and occurs primarily in Asia. Streptobacillus moniliformis causes rat-bite fever in America and the illness may include polyarthritis. • These bacteria are found in the mouth, nose and respiratory tract of rodents (especially rats). One to 36 days after the exposure the patient becomes ill and develops fever. Both of these are found in the mouths of rodents. Streptobacillus moniliformis is the only reported bacteria that causes RBF in North America while Spirillum minus is more common in Asia, also known as sudoku. Spirillum is microbiologically characterized as a … The course is subacute, and the diagnosis often is made retrospectively. Carter HV. 1888;3:45-48. Rat-bite fever transmitted by the Gram-negative coiled rod Spirillum minus (also known as Spirillum minor) is more rare, and is found most often in Asia.In Japan, the disease is called sodoku.Symptoms do not manifest for two to four weeks after exposure to the organism, and the wound through which it entered exhibits slow healing and marked inflammation. Rat-bite fever due to S. moniliformis (also called Haverhill fever) is more common in the USA and may be due to a rat bite or to exposure to contaminated milk or water during an outbreak. The recommended dosage would be 500 mg either p.o. A specialized laboratory can confirm the diagnosis if a sterile site is positive on culture. Joint manifestations are rare (1, 7). passed from rodent to human via the rodents urine or mucous secretions. Streptobacillary rat-bite fever can be diagnosed only by blood culture. Although S. minus can be propagated in mice or guinea pigs, there is little data regarding treatment of S. minus using this system. Postgraduate Med Journal. Antimicrobial therapy of ratbite fever. Symptoms of the streptobacillary form include fever, rash, and arthralgias. 1964;44:347-51. The organism is motile by means of bipolar flagella. Infection results … 179 This organism is widely distributed in nature, especially in fresh or salt water with organic debris. Spirillum minus is an organism associated with rat-bite fever and sodoku [1] [2] [3] that has never been fully identified and was assigned to the genus Spirillum in the early 1900s based on morphology, although it is not a validly published name. Spirillum minus can be seen on dark-ground illumination or by Leishman stains of blood or aspirate from infected glands. 7.5) of the family Spirillaceae, aquatic except for one species (S. minus) that causes a type of rat-bite fever in humans.Spirillum is microbiologically characterized as a gram-negative, motile helical cell with tufts of whip like flagella at each end. For instance, an individual bitten by an infected rat is likely to suffer from S. minus infection, commonly referred to as rat-bite fever. 4. They have a thick cell wall and lack an outer membrane. 29–33 S. minus is more common in Asia than in the US and elsewhere in North America, where most cases of rat-bite fever are caused by Streptobacillus moniliformis. This agent also may cause endarteritis. 2013. In Japan, infection caused by S. minus is known as Sodoku from So = Rat and Doku = Poison. moniliformis causes most cases of the disease in the United States.S. Complications of spirillar rat bite fever are rare. Without antimicrobial therapy, the fever abates over 3 to 5 days only to recur at regular intervals of 3 to 10 days. Spirillum minus was observed in the blood of 1 of the 4 mice, and on the eighteenth day it was present in the blood of all 4 mice. The investigators found that T. whipplei was the most common cause of culture-negative IE, accounting for 6.3% of such cases.490 However, other investigators have emphasized the principal role of Bartonella and Coxiella burnetii as etiologic agents in culture-negative IE.491 Thus, the etiology of culture-negative IE may vary significantly by geographic region. Infection occurs after being bitten by a rat. Other articles where Spirillum minus is discussed: rat-bite fever: …infection caused by the bacterium Spirillum minus (also called Spirillum minor) and transmitted to humans by the bite of an infected rat. Following defervescence, patients can be switched to oral ampicillin or penicillin V (500 mg po every 6 hours) to finish a 10 to 14 days course. Disease• Spirillum minus and Streptobacillus moniliformis arespecies of Spirillum.• Spirillum minus cause rat-bite fever illness caused by bacteria transmitted Rat Bite by rodents, rats, in most cases, which is Fever ?? Prior to the availability of penicillin, arsenicals were frequently used to treat patients infected with S. minus, apparently, with some degree of success (21). After investigating this, scientists … Rats can carry Spirillum minus and Streptobacillus moniliformis. 2014;52:2259-61. Streptobacillus moniliformis grows slowly on artificial media, but only in the presence of 15% blood and sera, usually 10 to 20% rabbit or horse serum incubated at reduced partial pressures of oxygen (Fox and Newcomer, 1990). Ronald G. Washburn, in Mandell, Douglas, and Bennett's Principles and Practice of Infectious Diseases (Eighth Edition), 2015. 15. Rat-bite fever can be caused by either of two different bacteria, Streptobacillus moniliformis or Spirillum minus. These animals carry organisms similar to those carried by mice and rats; ocelots carry organisms similar to those carried by cats. S. minus has not been cultivated on artificial media but can be identified on darkfield microscopy and, occasionally, in Wright- or Giemsa-stained smears of peripheral blood. 2007;21:963–996. Il s’agit d’une bactérie dont la forme en spirale est similaire à celle des spirochètes (voir figure Formes des bactéries). The fever is usually accompanied by a maculopapular or petechial rash that is most pronounced on the extremities. Table 73-1 lists organisms carried by small mammal pets. It is a form of rat-bite fever (RBF). Thomas M. Bashore, in Valvular Heart Disease: A Companion to Braunwald's Heart Disease (Third Edition), 2009. S. minus is exquisitely susceptible to penicillin. 98 moniliformis and Spirillum minus . Am J Dis Child. Tetracyclines should be avoided due to their association with tooth enamel agenesis and tooth staining. Because of its properties as a bacterial growth promoter, sodium polyanethol sulfonate, which is sometimes found in blood-based media, should not be used due to its inhibitory effects on S. moniliformis. S. minor is the etiologic agent of “rat-bite fever” (sodoku), but rodent to man transmission has not documented in the cases of endocarditis. Five cases of IE due to Spirillum minor, a spirochete, have been reported. Spirillum minus does not grow in vitro and requires inoculation of culture specimens into laboratory animals, with subsequent identification of the bacteria by dark-field microscopy. " An investigation into the effect of streptomycin and penicillin on Spirillum minus infections in mice, guineapigs and hamsters, showed that streptomycin effectively controlled Spirillum infections in guineapigs, but that this antibiotic was not always efficacious in mice and hamsters. Kebanyakan kasus terjadi di Jepang, tetapi penyakit ini juga dapat ditemukan di Amerika Serikat, Eropa, Australia, … Preexisting heart disease or severe underlying disease (e.g., aplastic anemia) was usually present, although one case occurred in an otherwise healthy person. However, Heilman and Hermel clearly demonstrated the efficacy of penicillin by treating one-half of 50 infected mice with penicillin (10). Kostenfreier Vokabeltrainer, Konjugationstabellen, Aussprachefunktion. Spirillum is a type of bacterium, invisible to the naked eye, that moves in a corkscrew-like fashion. A phase I antibody titer (usually IgG or IgA or both) greater than 1 : 200 is considered virtually diagnostic of C. burnetii IE and may be useful to monitor the response to therapy.478,483 Isolation of C. burnetii by inoculation of valve suspensions into a human fetal diploid fibroblast cell line seems to be a promising technique.484 DNA probes are under development. Although there are no studies to guide one, patients with relatively mild disease and no evidence of complications such as endocarditis or meningitis, can probably be treated with an oral regimen for the entire treatment course. every 8 hours for 3 days. S. minus is a tightly coiled, gram-negative spiral bacillus. Disease definition Rat-bite fever (RBF) is a systemic bacterial zoonosis occurring in individuals that have been bitten or scratched by Streptobacillus moniliformis or Spirillum minus-infected rats and characterized by high fever, a rash on the extremities, and arthralgia. Currently, penicillin is the drug-of-choice for the treatment of spirillar rat bite fever. A notable exception is Spirillum minus (S. minus), which is one of the two types of bacteria that can cause rat-bite fever. Penicillin remains the drug-of-choice for pediatric patients. Spirillum is microbiologically characterized as a gram-negative. 11. Although the optimum duration of therapy is unknown, based on limited data, treatment of meningitis for 10 - 14 days and endocarditis for 28 days should be sufficient. These bacteria are present in the oropharyngeal flora of approximately 50% of healthy wild and laboratory rats, as … Who is at higher risk for … 1. Alternate therapies include oral amoxicillin-clavulanate, 875 mg/100 mg twice daily (for 10–14 days), or oral or intravenous doxycycline, 100 mg twice daily (4). The disease can be fatal if untreated due to malignant endocarditis, meningoencephalitis, or septic shock. Wheeler is credited with reporting the first use of penicillin against S. minus (22). Les personnes contractent généralement l’infection lorsqu’elles sont mordues par un rat ou une souris. The organism, first described by Dr. Henry Van Dyke Carter in 1887, was previously known as Spirocheta morus muris, Sporozoa muris,  Spirochaeta laverani, Spironema minor, Leptospira morsus minor, Spirochaeta muris and Spirochaeta petit (8). Signs and symptoms. Spiral bacteria – Wikipedia What are three diseases cause by spirilla bacteria? Because S. minus has not been cultivated on synthetic media there are no in vitro data regarding the susceptibility of S. minus to antimicrobial agents. Around 1 – 4 weeks after the bite, the individual will develop a fever, headache, and pain at the site of the bite. Cell Structure and … Pediatr Clin N Am. Spirillum minus has never been grown in culture but, because both are causative agents of rat-bite fever, … Spirillum Species Spirillum minus (S. minus) The infection of bacterium Spirillum minus is usually passed to humans from infected rodents. Complications of S. minus infection are rare. Most pets, regardless of type, can carry Salmonella and Campylobacter spp. Ingestion of S. moniliformis via contaminated food causes Haverhill fever, so named for the first description of an outbreak in Haverhill, MA. [PubMed], 19. The organism is a short, thick, gram-negative, tightly coiled spiral rod which measures 0.2 to 0.5 μm and has two to six helical turns. Eugene D. Shapiro, in Principles and Practice of Pediatric Infectious Diseases (Fifth Edition), 2018. Other important clues are thrombocytopenia (seen in 90% of cases) and hypergammaglobulinemia. It cannot be cultured on an artificial media but it can sometimes be isolated using guinea-pig inoculation. Risk factors may include exposure to parturient cats or rabbits, previous valvulopathy, and pregnancy.480 The aortic valve is involved in more than 80% of the cases.
