Abstract
In order to understand the cow mastitis situation,kinds of pathogenic bacteria and drug resistance status, provide references for prevention in Weifang,100 milk samples were collected from 6 dairy cattle farms each with clin-ical or recessive mastitis in Weifang for pathogenic bacteria isolation and identification,resulting in bacteria detection rate of 91.50%. Milk samples with mixed bacteria infection reached 84.70%. 265 bacteria strains were isolated,includ-ing 38.11%Streptococcus strains(S. agalactiae,S. dysgalactiae and S. uberis),34.34%Staphylococcus aureus and 16.98%E. coli,forming the dominant pathogenic bacteria of dairy cow mastitis in Weifang. The drug sensitivity test of the dominant mastitis bacteria strains in Weifang indicated that the high sensitive drugs were cefquinome (80.59%), enrofloxacin(68.35%),ceftiofur(68.35%)and florfenicol(67.51%)and the high resistant drugs were penicillin(37.97%), streptomycin(26.16%)and tetracycline(10.55%).关键词
