Homotypic synonym:
Limosilactobacillus caviae (Killer et al. 2017) Zheng et al. 2020.
Gram-positive regular to slightly irregular rods, 0.4-0.8 / 1.2-8.5 µm, often constricted
in the middle occurring singly and in small clusters. Non-spore-forming. Non-motile.
Colonies are yellowish, disc shaped in profile, glossy, 1.1-2.4 mm in diameter after 3
days of anaerobic incubation at 37 ºC on MRS and TPY agar; 0.6-1.7 mm in diameter
under aerobic conditions. Facultative anaerobe. Grows at 10-45 ºC (optimally at 37
ºC). Grows at pH 4.5-8.5.
Isolated from the oral cavity of a 10-month-old male home-bred guinea pig (Cavia aperea f. porcellus). Habitat includes rat caecum.
Undetermined.
Obligately heterofermentative.
