The aqueous and ethanolic extract of Passion fruit (Passiflora edulis Sims) were investigated for their antimicrobial activity in the absence and presence of Zn(OAc)2.2H2O using the Disc Diffusion Assay under asceptic conditions. For the ethanolic extracts,( 1-3), the highest AZOI of 153.9 mm2 was induced by sample (1), 0.015g/ml of extract against C. albicans. The lowest AZOI of 15.9 mm2 was also induced by sample (3), 0.1g/ml of ethanolic extract against K. pneumoniae. There seems to be a general increase in AZOI as the conc of ethanolic extract increases. For sample (6 )and (7), 0.1g of Zn (OAc)2.2H2O in 10 ml aqueous extract and 1.0g of Zn(OAc)2.2H2O in 10 ml of aqueous extract respectively, it was observed that the highest AZOI of 67.2 mm2 was observed against E. coli, whereas the lowest AZOI of 21.6 mm2 was observed against C. albicans. The AZOI induced by sample (8), 1.0g of Zn (OAc)2.2H2O in 10 ml of aqueous solution is greater than sample (7), suggesting that Zn(OAc)2.2H2O augment the antimicrobial activity of the aqueous passion fruit extract. Antimicrobial selectivity was also observed. For example, against S. aureus, sample (1) exhibit AZOI of 32.2 mm2 whereas against C. albicans, AZOI of 153.9 mm2 was observed. For all experiments conducted, antimicrobial activity seems to be less than that of the standard antibiotics: Ampicillin and Nystatin. Nevertheless, the ethanolic and aqueous extracts of ripe passion fruit can be used as a natural antibiotics against a range of bacteria induced diseases.
