ABSTRACT: The in vitro antimicrobial activity of Cucumis anguria L. callus extract was studied against selected pathogenic fungi and bacteria, by well diffusion method.  Callus was extracted using Chloroform, Acetone, Methanol, Benzene, and Petroleum ether.  The callus extracted with methanol was most effective than other solvents used against pathogenic bacteria Escherichia coli, Streptococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa, Salmonella paratyphi and fungi Fusarium oxysporum, Aspergillus fumigatus, Candida albicans and Aspergillus flavus, Aspergillus niger. Acetone extracts showed maximum inhibitory activity (34.9mm) against Streptococcus aureus , whereas for fungal methanol extract exhibiting highest zone of inhibition (8.6 mm) against Candida albicans. Chloroform extract showed moderate range of inhibitory activity against bacterial pathogens and fungal pathogens. Benzene and Petroleum ether extracts were inefficient in inhibiting the bacterial and fungal growth, when compared to other extracts.
