Abstract

Maggot therapy's success is partly due to the ingestion and killing of living microorganisms. The aim of this study was to investigate the antibacterial activities of maggots’ crude extracts (DMSO and PBS extracts) and excretion/secretion of Chrysomya albiceps (Diptera: Calliphoridae). The excretion/secretion (E/S) and crude extracts were collected from third larval instars of C. albiceps. The extracts were tested against Escherichia coli and Pseudomonous aeruginosa, as Gram-negative bacteria and Staphylococcus aureus and Bacillus subtilis as Gram-positive bacteria. Antimicrobial activity was done by calculating the reduction percentage of the colony's growth. The E/S was appeared the highest antibacterial activities against Gram-positive and Gram-negative bacteria, while the PBS extract has appeared the lower antibacterial activities. Generally, the E/S of C. albiceps maggot was found to be more effective as antibacterial agents than crude extracts (DMSO and PBS extracts).
