infection in a young immunocompetent male caused by streptobacillus felis a putative zoonotic microorganism transmitted by cats
Clinical Infectious Diseases, 2020Co-Authors: Ulrich Matt, Ahmad Fawzy, Judith Schmiedel, Janina Trauth, Katja Schmidt, Klaus Vogel, Susanne Herold, T Karrasch, Can Imirzalioglu, Tobias EisenbergAbstract:Rat bite fever (RBF) is predominantly caused by Streptobacillus Moniliformis. We report a human infection with Streptobacillus felis. Clinical presentation was consistent with RBF, but serologic testing was negative for S. Moniliformis. Eventually, S. felis specific sequences were detected in skin lesions of the patient and in the oropharynx of local cats.

streptobacillus notomytis sp nov isolated from a spinifex hopping mouse notomys alexis thomas 1922 and emended description of streptobacillus levaditi et al 1925 eisenberg et al 2015 emend
International Journal of Systematic and Evolutionary Microbiology, 2015Co-Authors: Tobias Eisenberg, Werner Nicklas, Koichi Imaoka, Christa Ewers, Stefanie P Glaeser, Norman Mauder, Torsten Semmler, Jorg Rau, Nicola Hofmann, Masanobu KimuraAbstract:A pleomorphic, Gram-negative, rod-shaped, indole-, oxidase- and catalase-negative, non-spore-forming, non-motile bacterium was isolated in 1979 from the heart of a spinifex hopping mouse (Notomys alexis Thomas, 1922) with septicaemia and stored as Streptobacillus Moniliformis in the strain collection of the Animal Health Laboratory, South Perth, Western Australia (AHL 370-1), as well as under CCUG 12425. On the basis of 16S rRNA gene sequence analyses, the strain was assigned to the genus Streptobacillus, with 99.4 % sequence similarity to the type strain of Streptobacillus Moniliformis, 95.6 % sequence similarity to the type strain of Streptobacillus hongkongensis and 99.0 % sequence similarity to the type strain of Streptobacillus felis. The clear differentiation of strain AHL 370-1T from Streptobacillus Moniliformis, Streptobacillus hongkongensis and Streptobacillus felis was also supported by rpoB, groEL and recA nucleotide and amino acid sequence analysis. Average nucleotide identity was 87.16 % between strain AHL 370-1T and Streptobacillus Moniliformis DSM 12112T. Physiological data confirmed the allocation of strain AHL 370-1T to the family Leptotrichiaceae, considering the very similar profiles of enzyme activities and fatty acids compared to closely related species. Within the genus Streptobacillus, isolate AHL 370-1T could also be separated unambiguously from the type strains of Streptobacillus Moniliformis, Streptobacillus hongkongensis and Streptobacillus felis by MALDI-TOF mass spectrometry. Two further strains (KWG2 and KWG24) isolated from asymptomatic black rats in Japan were highly similar to AHL 370-1T. On the basis of these data, we propose the novel species Streptobacillus notomytis sp. nov., with the type strain AHL 370-1T ( = CCUG 12425T = DSM 100026T = CCM 8593T = EF 12425T).

streptobacillus felis sp nov isolated from a cat with pneumonia and emended descriptions of the genus streptobacillus and of streptobacillus Moniliformis
International Journal of Systematic and Evolutionary Microbiology, 2015Co-Authors: Tobias Eisenberg, Werner Nicklas, Stefanie P Glaeser, Norman Mauder, Matthias Contzen, Khayrieh Aledelbi, Peter KampferAbstract:A pleomorphic, Gram-stain-negative, rod-shaped, indole-, oxidase- and catalase-negative, non-spore-forming, non-motile bacterium (strain 131000547T) was isolated from the lungs of a cat with pneumonia. On the basis of 16S rRNA gene sequence analyses the strain was assigned to the genus Streptobacillus with 97.6 % sequence similarity to the type strain of Streptobacillus Moniliformis and 94.6 % to that of Streptobacillus hongkongensis. The clear differentiation of strain 131000547T from Streptobacillus Moniliformis and Streptobacillus hongkongensis was also supported by gyrB, groEL, and recA nucleotide and amino acid sequence analysis. DNA–DNA hybridization demonstrated ≤ 19.9 % (reciprocal 28.7 %) DNA–DNA relatedness between strain 131000547T and Streptobacillus Moniliformis DSM 12112T. Physiological data confirmed the allocation of strain 131000547T to the family Leptotrichiaceae. Strain 131000547T has a unique profile of enzyme activities allowing differentiation from the most closely related species. Within the genus Streptobacillus, isolate 131000547T could also unambiguously be separated from Streptobacillus Moniliformis and Streptobacillus hongkongensis by both matrix-assisted laser desorption ionization time-of-flight mass spectrometry and Fourier transform-infrared spectroscopy. On the basis of these data, a novel species of the genus Streptobacillus, Streptobacillus felis sp. nov., is proposed with the type strain 131000547T ( = DSM 29248T = CCUG 66203T = CCM 8542T). Emended descriptions of the genus Streptobacillus and of Streptobacillus Moniliformis are also given.

Rat bite fever.
Veterinary Microbiology, 2008Co-Authors: Wim Gaastra, Hoa T.k. Ho, Ron Boot, Len J.a. LipmanAbstract:Abstract Rat bite fever (RBF) is a bacterial zoonosis for which two causal bacterial species have been identified: Streptobacillis Moniliformis and Spirillum minus . Haverhill fever (HF) is a form of S. Moniliformis infection believed to develop after ingestion of contaminated food or water. Here the infectious agents, their host species, pathogenicity (virulence factors and host susceptibility), diagnostic methods, therapy, epidemiology, transmission and prevention are described. Special emphasis is given on information from the field of laboratory animal microbiology and suggestions for future research.

Dogs as vectors of Streptobacillus Moniliformis infection?
Veterinary microbiology, 2007Co-Authors: Erik G H Wouters, Len J.a. Lipman, Wim GaastraAbstract:Rat bite fever is a bacterial zoonosis transmitted through the bite of rats. One of the two etiological agents that cause rat bite fever is Streptobacillus Moniliformis. Rat bite fever is rare and very likely under diagnosed but occurs worldwide. Other animals, like dogs and cats that have mouthed a rat are often mentioned in the literature as potential risks for the attraction of rat bite fever. However, rat bite fever caused by the bite of a dog or cat has very seldom been documented. Therefore, to identify the possible risk for humans to become infected with S. Moniliformis after having been bitten by a dog that has been in contact with rats, the presence of S. Moniliformis in the mouth of these dogs was tested with molecular methods. Swabs taken from the mouth of 18 dogs with proven contacts with rats were tested for the presence of S. Moniliformis DNA by PCR. An amplicon of the right size was obtained in 10 of the 18 dogs. Nucleotide sequencing of five amplicons of PCR positive samples demonstrated the presence of S. Moniliformis DNA in the mouth of three dogs. A bite by these dogs therefore might infect humans with S. Moniliformis and cause rat bite disease.

streptobacillus Moniliformis bacteremia in a rheumatoid arthritis patient without a rat bite a case report
BMC Research Notes, 2015Co-Authors: Takahito Nei, Akiko Sato, Kazunari Sonobe, Yoshihiko Miura, Kenji Takahashi, Ryoichi SaitoAbstract:Rat bite fever is a relatively rare infectious disease due to infection with Streptobacillus Moniliformis or Spirillum minus mainly via directs bite by rats, mice, or other rodents. If there is no clear bite history, the diagnosis is difficult or may not be made. A 72-year-old Asian female with rheumatoid arthritis was admitted for high grade fever and walking difficulty with severe lumbago. Initially, we suspected lumber compression fracture with deterioration of rheumatoid arthritis, but Gram-negative bacilli were isolated from blood culture during hospitalization. The isolated organism was identified as S. Moniliformis by 16S ribosomal ribonucleic acid (rRNA) sequencing. S. Moniliformis is well known to be a primary causative organism of rat bite fever, but this patient had no history of rat bite. Had S. Moniliformis bacteremia not been detected, she might have been treated for rheumatic exacerbation. We emphasize the importance of performing appropriate microbial culture testing for identifying potential infectious diseases. We also conclude that S. Moniliformis infection can become established with contaminated vehicle contact alone, not only as a direct result of a bite. We must keep mind that those working in places where rodents breed or are at risk of contact with rats or mice might be at risk for contracting this unusual disease.

positive streptobacillus Moniliformis pcr in guinea pigs likely due to leptotrichia spp
Veterinary Microbiology, 2008Co-Authors: R Boot, Lia Van De Berg, Frans A G Reubsaet, Maurice J VlemminxAbstract:Streptobacillus Moniliformis is a zoonotic bacterium. We obtained positive S. Moniliformis PCR results in oral swab samples from guinea pigs from an experimental colony and the breeding colony of origin. Comparison of the DNA sequence of an amplicon with deposited 16S rDNA sequences revealed that Leptotrichia sp. can be the source of a false positive S. Moniliformis PCR outcome.

resistance to infection of guinea pigs with a rat streptobacillus Moniliformis
Scandinavian Journal of Laboratory Animal Science, 2007Co-Authors: R Boot, J. L. Veenema, Lia Van De Berg, M A Koedam, Maurice J VlemminxAbstract:A rat S. Moniliformis strain was dosed, orally and nasally, to two groups of 12 guinea pigs aged 10-15 weeks and 4-5 weeks respectively. In the first experiment 3 animals were sacrificed 1, 2, 4 and 6 weeks after infection and S. Moniliformis was detected by culture in one animal at 2 weeks and by PCR in two animals at 4 weeks. In the second experiment 4 animals were sacrificed 2, 4 and 6 weeks after infection and S. Moniliformis was not detected by culture and PCR in any animal. Seroconversion to S. Moniliformis was found from 2 weeks after infection in 3 of 12 and 7 of 12 guinea pigs respectively. Clinical signs and gross lesions in the ventral cervical area and the lungs were not observed in any animal. We conclude that guinea pigs seem difficult to infect with a rat S. Moniliformis strain.Â

detection of antibodies to streptobacillus Moniliformis in rats by an immunoblot procedure
Laboratory Animals, 2006Co-Authors: R Boot, Lia Van De Berg, Maurice J VlemminxAbstract:An immunoblot (IB) technique for detecting antibodies to Streptobacillus Moniliformis in rat sera was evaluated. Immune sera to three S. Moniliformis strains showed a similar reactivity pattern with both autologous and homologous antigens in the 18-87 kDa range. Using a rat S. Moniliformis strain as the antigen, a similar reactivity pattern was found with sera from rats infected experimentally with S. Moniliformis and sentinels. Two to five proteins were detected in the 32-55 kDa range. Over a period of 2.5 years, 27/133 rat serum panels submitted for routine monitoring yielded one or more S. Moniliformis enzyme-linked immunosorbent assay (ELISA)-positive samples. In one of these 27 panels, sera showed an IB reactivity pattern resembling that observed with immune sera and with sera from infected and exposed rats. S. Moniliformis was confirmed in the colony by both culture and polymerase chain reaction (PCR). Sera from the remaining 26 ELISA-positive serum panels frequently showed activity to a 57 kDa antigen but not more than one antigen was detected in the 32-55 kDa range. We conclude that the IB can be used as a confirmatory test for the detection of S. Moniliformis infection in ELISA-positive rats.
