Abstract Streptobacillus felis is a fastidious microorganism and a novel member of the potentially zoonotic bacteria causing rat bite fever. Since its description, this is the second isolation of S. felis in a diseased member of the Felidae. Interestingly, the strain from this study was isolated from a zoo held, rusty-spotted cat (Prionailurus rubiginosus), with pneumonia, thereby indicating a possible broader host range in feline species. A recent preliminary sampling of domestic cats (Felis silvestris forma catus) revealed Electronic supplementary material The online version of this article (https://doi.org/10.1007/s10482-020-01454-x) contains supplementary material, which is available to authorized users.

that this microorganism is common in the oropharynx, suggesting that S. felis is a member of their normal microbiota. Due to unawareness, fastidiousness, antibiotic sensitivity and lack of diagnostics the role of S. felis as a cat and human pathogen might be underreported as with other Streptobacillus infections. More studies are necessary to elucidate the role of S. felis in domestic cats and other Felidae in order to better estimate its zoonotic potential.

Introduction
Materials and methods
Streptobacillus (S.) moniliformis (Leptotrichiaceae, Fusobacteriales) has been the longstanding unique species in this genus (Levaditi et al. 1925). This bacterium represents the most important causative microorganism of rat bite fever (RBF) and its foodborne
