Streptobacillus canis sp. nov. isolated from a dog

Abstract

The GenBank/ENA/DDBJ accession numbers for the gene sequences of 16S rRNA, gyrB, groEL and recA as well as for the complete genome sequence of strain IHIT1603-19 T are MN636430, MN736717-MN736719 as well as WOEI00000000 (BioSample SAMN13381658; BioProject PRJNA591425), respectively.

Streptobacillus felis, a member of the oropharynx microbiota of the Felidae, isolated from a tropical rusty-spotted cat

“…In this second report, again lungs were predominantly affected, but streptobacilli were isolated from all major organs pointing towards an agonal spread of these bacteria or an early septicemia. Likewise, the next closely related species, S. canis , has recently been found to also constitute a member of canine oral microbiota (Matt et al 2020 ) and has been isolated from a phlegmon on a dog’s hindleg (Eisenberg et al 2020b ). Hypothesizing that bite wounds are often caused by oral microbiota (Abrahamian and Goldstein 2011 ), one can speculate that streptobacilli from cats might occasionally also be involved in wound infections.…”

“…Mass spectrometry procedure has been recently described in detail (Eisenberg et al 2018 , 2020b ). The commercial database used (DB 8,468; BrukerDaltonics) comprised 24 spectra each from 10 S. moniliformis strains.…”

“…The commercial database used (DB 8,468; BrukerDaltonics) comprised 24 spectra each from 10 S. moniliformis strains. Reference spectra from well-characterized, quality-controlled strains of all other Streptobacillus / Pseudostreptobacillus species and most other members of the Leptotrichiaceae were added to the database from previous studies (Eisenberg et al 2020b ; Rau et al 2016 ). Identification was done with the commercial Bruker database, and with the extended database.…”

“…However, the proper identification of these microorganisms was not carried out and such isolates have not been stored. Recently, [ S. ] hongkongensis (Woo et al 2014 ), S. felis (Eisenberg et al 2014 ), S. notomytis (Eisenberg et al 2015b ), S. ratti (Eisenberg et al 2016 ) and S. canis (Eisenberg et al 2020b ) were described as novel species. Whereas S. notomytis and S. ratti are closely associated with black rats ( Rattus rattus ), [ S. ] hongkongensis has exclusively been isolated from humans (Lau et al 2016 ; Woo et al 2014 ) and was recently found to belong to a novel genus, Pseudostreptobacillus (Eisenberg et al 2020a ).…”

“…S. felis and S. canis were only once isolated from clinical disease in animals, i.e. from a cat with pneumonia and a dog with phlegmon, respectively (Eisenberg et al 2015a , 2020b ). However, with respect to zoonotic potential, S. notomytis has been found to also cause RBF in humans (Fukushima et al 2017 ; Ogawa et al 2018 ) and a similar case of RBF could recently be attributed to S. felis for the first time (Matt et al 2020 ).…”
