Abstract
Ninty-one strains of bacteria were isolated from the milk of dairy cows with subclinical mastitis in huhhot area.Results showed that 72 strains of them were Staphylococcus aureus,8 were Staph.hemolyticus,6 of them were S.epidermidis;1 was Staphylococcus dysgalactiae;2 were Bacillus coli,1was Serratia and 1 of them was Klebsiella.Mice and sheep blood test demonstrated that some strains of them were proved pathogenic.Drug sensitivity test showed that the Staphylococcus aureus and S.haemolytius were sensitive to Tetracyclline,Chorampheniol,Gentamiccin and kanamycin;Sreptococis was sensitive to Eythrocin,Chloromycetinum and Gentamycinum,Bacillus was sensitive to Novobicocinum Sulfanimidum.Strepomicinum and Gentamycinum,but they induced resisitance to Peniciuin and Strepomicinum which used frequently in clinic.
