Abstract: | An investigation of Mastitis in cattle was carried out in Anand city and in nearby villages of Gujarat state using California Mastitis Test (CMT) kit. The prevalence of clinical and subclinical mastitis was found to be 5.5% and 15.75%, respectively. Staphylococcus aureus was identified through strain specific polymerase chain reaction; the remaining isolates identified on the basis of molecular analysis by 16S rDNA sequencing and phylogenetic analysis were Staphylococcus species, B. pumilus, Staphylococcus chromogenes, Bacillus species, and Pseudomonas species. In vitro antimicrobial susceptibility pattern of all the isolates was checked against 13 different antibiotics using the agar disc diffusion method. Highest bacterial resistance was observed with penicillin G and oxacillin antibiotics. It was also observed that the patterns of bacterial resistance have not changed in India over the years. The data supports the decrease in the incidence of mastitis but the rate of decrease is minimal. More effective control strategies are required. |
