ANTIBIOGRAM ANALYSIS OF BOVINE MASTITIS-CAUSING BACTERIA ISOLATED FROM NEARBY FARMS OF LAHORE

Bovine mastitis has become major issue globally.This research is performed for investigating the current status of clinical mastitis among dairy cattle of farms of Lahore.The prevalence of mastitis was assessed by the results of the bacteriological evaluation of milk samples collected from clinical mastitis cases from farms in and nearby Lahore.Mastitic cattle and buffalos from farms nearby Lahore, Pakistan, have a high prevalence of multidrug-resistant bacteria.The main bacterial pathogen linked to mastitis was Staphylococcus aureus, followed by E.coli and S. dysgalactiae.This indicates that unhygienic and unsatisfactory management practices are being followed on the nearby farms.About 42 different mastitogenic bacteria including Staphylococcus aureus (28), Escherichia coli (12), and Streptococcus dysgalactiae (2) were isolated from the 47 confirmed clinical cases of mastitis affected cows and were further processed for antibiotic resistance profiling.The prevalence of major pathogens isolated was prevalence of 66.67%, 28.57%, and 4.76%, respectively.The results are similar to the earlier report of S.aureus (34%), E.coli (19%), and Streptococci spp.(9%) by Australia.Antibiogram analysis were also performed for these isolates shows that Gentamicin, Ciprofloxacin and Meropenem can be used as efficient antimicrobial agents for the treatment of bovine mastitis.This study has shown that microbiological and antibiogram analysis is very important for treatment and control of the mastitis.
