First Report of Streptococcus ruminantium in Wildlife: Phenotypic Differences with a Spanish Domestic Ruminant Isolate

Streptococcus ruminantium is a recent reclassification of the former suis serovar 33. Although knowledge about S. extensive, information on host range and pathogenic potential still scarce. This bacterium has been isolated from lesions in domestic ruminants, but there are no reports wild animals. Here, we provide associated with Pyrenean chamois (Rupicapra pyrenaica) sheep NE Spain, as well phenotypic biopatterns antimicrobial resistance (AMR) isolates. Overall, caused by were similar to those suis, excluding polyserositis. Heterogeneity profiles was observed within strains VITEK-2, resulting only two tests common all isolates different suis: Alpha-Galactosidase Methyl-B-D-Glucopyranoside, both positive for negative strains. Isolates susceptible antimicrobials tested, except danofloxacin, whereas isolate resistant tetracycline. In conclusion, can cause infection be pathology ruminants. Due its diversity, specific PCR optimal identification routine diagnosis.
