The diagnosis, isolation of etiological agents and antibiotic susceptibility test results in cows and buffalos suffering from subclinical mastitis

Abstract

In this study, diagnosis, isolation of microbiological agents and antibiotic susceptibility results were comparatively determined on sufoclinically mastitic cow's and buffalos in the same farm at differents seasons. The cell counts of the milk samples collected according to the scores of CMT in cows and buffalos were 1.700.000 ± 320.000 and 1.340.000 ± 290.000 respectively. The incidence of subclinical mastitis cases Were between 6.73 -17.25 % in cows and 4.68 -16.25 % in buffalos during the period of study. On the other hand high incidence was observed during summer months. The staphylococcus spp were on the top levels as a 26.19 % in cows and 37.50'% in buiffalos. Following this, Corynebacterium spp rates in cows and buffalos were 30.95 % and 8.33 % respectively. In additon to these, Streptococcus spp, E. coli, K. pneumonia, E. aeruginosa, B. cereus, Anaerobic gram (+) bacillus, Aspergillus spp, Penicillum spp, Candida spp were also isolated in low rates. Antibiotic susceptibility test results were screened on the table. The differences statistically was not important in the subclinical mastitis incidence rates, microorganisms and effective antibiotics between the cows and buffalos.
