abstract= 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.,
