In vitro Efficacy of Emblica officinalis Against MRSA Isolated from Buffaloes Suffering from Subclinical Mastitis

The present study describes in-vitro efficacy of Emblica officinalis against Methicillin Resistant S. aureus mastitis. Diffusion technique was used to assess in-vitro efficacy of Emblica officinalis. Zone of inhibition was measured and used to compare the in-vitro efficacy. The zone ranged between 10–13 mm with maximum zone of 13 mm observed in 200 and 225 mg/ml DMSO disc, followed by 12 mm in 175 and 150 mg/ml DMSO disc, 11 mm in 125 mg/ml DMSO disc and 10 mm in 100 mg/ml DMSO disc. The results indicate that the sensitivity pattern for Emblica officinalis at 200 & 175 mg/ml DMSO concentration and was comparable with the standard antibiotics in Methicillin sensitive S. aureus. In Methicillin resistant S. aureus isolates, the zone of inhibition was in the order Oxytetracycline (15mm) followed by Emblica officinalis-200 (13 mm) and Methicillin, ampicillin, gentamicin, ofloxacin were resistance.
