Background: The search for newer sources of antibiotics is a global challenge pre-occupying
research institutions, pharmaceutical companies and academia, since many infectious agents are
becoming resistant to synthetic drugs.
Aim: This present study sought to investigate the antibacterial potential of ethanolic and aqueous
extracts of Carica papaya leaves.
Materials and Methods: Fresh and healthy leaves of C. papaya were harvested, air dried and
milled into powder. The powder was extracted using ethanol and water as solvents. The
antibacterial activities of both extracts were determined by diffusion method. Nutrient agar medium
was prepared using standard method. Pure cultures of Coliform bacillus, Staphylococcus
epidermidis, Streptococcus viridans, Salmonella typhi and Escherichia coli were obtained from the
Department of Veterinary Microbiology and Parasitology, Federal University of Agriculture, Abeokuta, Nigeria. The extracts were serially diluted to obtain 1.0%, 0.5%, 0.25% and 0.125%
