Methicillin resistant Staphylococcus aureus (MRSA) strains being a major pathogen associated with mastitis of dairy animals, the study was proposed for investigating antimicrobial activity of lactobacilli of dairy animals having activity against the MRSA isolates of subclinical mastitis. Twenty two Lactobacilli were isolated from milk of healthy animal and screened for inherent antimicrobial activity with agar spot technique against indicator strain L. acidophilus, out of which eleven isolates exhibited strong inhibitory activity. The cell free filtrates of these isolates were then tested in vitro against MRSA by employing agar well diffusion and agar disc diffusion tests. Zone size indicative antimicrobial activity against MRSA possessing a very strong (15-18 mm) to moderately strong (10-14 mm) efficacy was observed in L. plantarum strains belonging to buffaloes (B5 and B8) and goats (G2 and G6), followed by sheep (S3). Moderate inhibitory activity (6-9 mm) was also observed for L. paraplantarum strain from cow (C2).
