ANTIMICROBIAL SUSCEPTIBILITY RATES IN GRAM-POSITIVE CATALASE-NEGATIVE COCCI FROM SHEEP AND GOAT GENITAL MICROBIOTA.

Gram-positive catalase-negative cocci (GPCNCs) are significant components of the genital microbiota in sheep and goats. However, characterizing them can be difficult due to overlapping culture features and the limited information on their susceptibility to antibiotics. In this study, 97 foreskin and 13 vaginal swabs were investigated using a culturomic approach. Of 110 animals, 76 (69.09%) hosted GPCNCs, including strains from Streptococcaceae (37, 33.64%), Aerococcaceae (30, 27.27%), Enterococcaceae (6, 5.45%) and other minor species. With increasing antimicrobial resistance rates in livestock, surveillance programs are globally required, so we conducted a pilot study on GPCNCs isolated from the genital mucosa surfaces of sheep and goats using the minimal inhibitory concentration assay (MIC). Due to gaps in interpretative standard breakpoints, normalized resistance interpretation was used for setting epidemiological susceptibility cut-off values (CO
