Lactic acid bacteria species were molecularly identified in milk from Lacaune, Santa Inês and crossbred sheep breeds and their in vitro probiotic potential was evaluated. The species identified were Enterococcus faecium (56.25%), E. durans (31.25%) and E. casseliflavus (12.5%). No other lactic acid bacteria species, such as lactobacilli, was identified. Most of the isolated enterococci were resistant to gastric pH (2.0) and to 0.3% oxgall. All tested enterococci were resistant to ceftazidime, oxacillin and streptomycin and sensible to clindamycin, erythromycin and penicillin. The resistance to ciprofloxacin, gentamicin, tetracycline and vancomycin varied among tested species. All tested enterococci strongly inhibited (P<0.05) Escherichia coli and... |

ABSTRACT Bovine digital dermatitis (BDD) is an infectious and contagious disease characterized by ulcerative and proliferative lesions affecting the skin on the bulbs of the heel or the interdigital cleft in dairy cattle, often associated with lameness. Evidences on the etiology of BDD indicate that it is multifactorial, involving environmental factors and multiple bacterial colonization. We isolated and identified microorganisms from BDD biopsy samples obtained from five Holstein Friesian and two Jersey cows by cultivation and molecular identification of bacterial isolates using 16S rRNA gene sequence analysis. We identified six bacterial species: Spirochetes as Treponema pedis and Leptospira broomi/L. fainei, L. licerasiae/L. wolffii; Corynebacterium... |
