Abstract:The antimicrobial activities of crude haemolymph extracts from Musca domestica larva were determined using 4 species of bacteria (Escherichia coli, Staphylococcus aureus, Bacillus magaterium and Bacillus subtilis). Results showed that each dosage of crude haemolymph extracts from M. domestica larva had a certain antimicrobial activities on the 4 tested bacteria. The highest antimicrobial rate of crude haemolymph extracts was observed on S. aureus, and followed by E. coli, B. subtilis and B. magaterium. The antimicrobial rate at the dosage of 0.8 mg/mL were 51.09%, 48.66%, 43.27% and 40.62%, respectively. Additionally, no significant difference was observed between the antimicrobial rates of each dosage of crude haemolymph extracts on different bacteria. The antimicrobial rate would increase with increasing the dosages of crude haemolymph extracts. Moreover, the diameter of inhibition zone of crude haemolymph extracts at the dosage of 0.8 mg/mL on the four bacterias were 12.00 mm, 12.22 mm, 9.11 mm and 10.33 mm, respectively, which were significant larger than control, but lower than cephalosporin.
