The Investigation Of Epidemiology Of Bovine Mastitis And Isolation And Identification Of Pathogenic Bacteria In One Farm Of Hefei

The intension of this study is to find out the leading pathogens causing bovine subclinical and clinical mastitis and effective treatments to certain pathogens. In order to know the incidence of bovine subclinical and clinical mastitis, we investigated the cattle farm in HeFei.In the epidemiologic investigation, the incidence of bovine clinical mastitis were 5.26%,6.27%,4.81%,7.87% in four different sections. By SARS, the difference was not markedness between forword and back(P=0.2062>0.05);the difference was not markedness between left and right (P=0.798>0.05),so the difference was not markedness in four different sections. The incidence of bovine subclinical mastitis wre16.92%,10.70%,11.11%,17.23% in four differents sections. By SARS,the difference was not markedness between forword and back( P>0.05); the difference was not markedness between left and right (P>0.05), so the difference was not markedness in four different sections.The incidence of bovine mastitis were 22.18%,16.97%,15.92%,25.1% in four differents sections. By SARS,the difference was not markedness between forword and back( P>0.05); the difference was not markedness between left and right (P>0.05), so the difference was not markedness in four different sections.The incidence of bovine mastitis has affinity about month. By SARS, the difference was markedness (P<0.001)in different months of bovine clinical mastitis,also the difference was markedness (P<0.001)in different months of bovine subclinical mastitis, the difference was markedness (P<0.001)in different months of bovine mastitis. Summer and season conversion, the incidence of bovine mastitis was high.The incidence of bovine mastitis has some relationship about breeding times.The breeding times increasing, the incidence of bovine mastitis was high. 43 bacterial strains were isolated form 30 milk samples of clinical mastitis, including Staphylococcus,Enterobacteriaceae, Fungus. E. coli were 11strains(18.60%), Proteus were 2strains(4.65%),Shigellawas 1 strain(2.33%), epiphyte were 26strains(60.47%), Staph. aureus 4 strains (9.30%), Staph. Epidermidis 2 strains (4.65%).,The leading pathogen causing bovine subclinical and clinical mastitis was epiphyte.The drug susceptibility testing indicates that, Ampicillin, Rocephin, Cifran, Brazan had good inhibitory effect on E.coli.. Ketoconazole Capsules, Nystatin had good inhibitory effect on epiphyte, Amikacin Sulfate, Gentamycin Sulphate CAS, Enrofloxacin, Cefalexin, Rocephin, RFP had good inhibitory effect on Staphylococcus Aureus. Amikacin Sulfate , streptomycin had good inhibitory effect on Proteus. Enrofloxacin, Cefradine, Rocephin, Cifran, RFP, Brazan had good inhibitory effect on Shigellawas.We cure bovine mastitis, should use sensitivity druggery together.
