Abstract:
The study was conducted on a group of 10 cows,
belonging to Bălţată cu Negru Românească breed, at the Cattle Research
and Development Station of Dancu , Iaşi district. Genital secretions were
sampled from puerperal cows (first 4 post-partum weeks), for determining
the uterine bacterial flora and germ susceptibility to different antimicrobial
products. The obtained results have shown a lower germ susceptibility in
the first post-partum week, compared to the next weeks. In weeks 2,3 and 4
post-partum , the mean values of germ susceptibility to antibiotics had very
high levels (90-100%) to Rifampine, Erythromycin, Cephalotin, average
levels (70-83.3%) to Amoxicillin, Kanamycyn, Chloramphenicol,
Streptomycin, Gentamicyn, bacteria showing resistance to Penicillin,
Oxacicllin, Sulphametazol, Methycillin. The most frequent bacterium
isolated from genital secretions of cows with inflammatory genital troubles
was Arcanobacterium pyogenes, in single bacterial colony (31.6%) or in
mixed bacterial colony with E.coli (5.3%).
