In many developing countries,herbal medicine is one of the primary health care systems as well. In this regard, the antimicrobial effects of methanol extracts of fruit of Opuntia stricta were studied. Fruit methanol extract prepared by maceration method and its inhibitory effect on four bacteria Staphylococcus aureus, Gram-negative Escherichia coli(two strains) and one fungi named Candida albicans were investigated. MIC of the extract was determined as well. Results showed that the methanol extract of fruits of Opuntia stricta have antibacterial effects against tested microorganisms. MIC values about Staphylococcus aureus(PTCC 1764), Escherichia coli (PTCC 1270), Escherichia coli (PTCC 1330) and Candida albicans(PTCC 5027) were 10, 40, 20 and 40 mg/ml respectively. The present study reveals the antimicrobial activities of fruit of Opuntia stricta.
