A study on treatment of resistant mastitis in dairy cows
Article Main
Abstract
The study was undertaken to determine the prevalence and treatment of antibiotic resistant mastitis in dairy cows. The predominant resistant causative pathogen was Escherichia coli (50.64 %) followed by S. aureus (44.25 %) and Methicillin resistant Staphylococcal aureus (5.11%).These isolates were found sensitive to gentamicin, enrofloxcain, amoxicillin+sulbactam, ceftriaxone and resistant to amoxicillin, oxytetracycline, penicillin G and oxacillin. In all the treatment groups of E. coli, S. aureus and MRSA mastitis, the post treatment pH, SCC was significantly (P < 0.01) decreased when compared to pre treatment pH, SCC values and the post treatment electrical conductivity was significantly (P < 0.01) increased when compared to pre treatment electrical conductivity value. In E. coli mastitis, treated with amoxicillin+sulbactam, ceftriaxone, enrofloxacin and gentamicin showed 74.1%, 67.75 %, 76.67 % and 64.52 % clinical recovery and in S. aureus mastitis, showed 65.25 %, 65.25 %, 72.43 % and 68.98 % clinical recovery. In MRSA mastitis, enrofloxacin was found to be highly effective in comparison to amoxicillin+sulbcactam.
