ANTIMICROBIAL ACTIVITY FOR EXCRETION AND SECRETION OF THE GREENBOTTLE FLY LARVAE LUCILIA SERICATA (MEIGEN) (DIPTERA: CALLIPHORIDAE)

Sterile larval excretion/secretion (es) exhibited antibacterial activity against some species of bacteria. they were shown to inhibit the growth of gram-positive bacteria staphylococcus aureus and bacillus subtilis gram-negative bacteria pseudomonas aeruginosa,escherichia coli and klebsiella pneumoniae and fungi geotricum candidum and aspergillus fumigatus thus exhibited limited inhibitory effect towards gram-positive bacteria streptococcus pyogenes and staphylococcus epidermidis and gram-negative proteous vulgaris and fungi syncephalastrum racemosum,candida albicans,that effect was slowed down when challenged with secretion on a solid media but no zone of complete inhibition was detectqd. growth inhibiting activity was determined in liquid growth media using the gram-positive,gram-negative bacterial and fungal strains as indicator organisms.
