Abstract:
This research was done to determine whether the ethanol leaf extract of marigold (Tagetes patula) has any antibacterial effects on Methicillin resistant Staphylococcus aureus MRSA was isolated and identified from mastitic samples with acute clinical mani festations. For the purpose of identifying MRSA.167 clinical mastitic samples were collected and put in various culture media. Out of 167 samples of milk, 11 (22%) were discovered to contain MRSA. The MRSA isolates were then evaluated using the agar disc diffusion met hod for antibacterial susceptibility at various concentrations of ethanolic marigol d leaf extract. The zone of inhibition of MRSA was examined using ethanol leaf extract at various concentration (5, 10, 15, 20, 25, 30, 35, 40 and 50 mg/ml).The results showed MRSA antibacterial activity at a concentration of 20 mg/ml. At a concentration of 50 mg/ml, the zone of inhibition's mean value was found to be at its maximum.
