Abstract

 ESSENTIAL OILS are widely used for their medicinal properties. They block adhesion and colonization of pathogenic microbes to epithelial cells which associated with bacterial resistance to antibiotics. So, this study investigates the effect of Lucilia sericata (flesh fly-an ectoparasite) excretions of non-irradiated and irradiated maggot and some essential oils on biofilm formation by tube method, antimicrobial susceptibility by agar disc diffusion method as well as on their anti-adherent activity by spectrophotometric method. The results showed that excretions and secretions (E/S) of non-irradiated and irradiated maggots (at 20 Gy), as well as (clove and cinnamon oils) did not have antibacterial activity against the tested bacterial strains Pseudomonas aeruginosa (P. aeruginosa), Staphylococcus aureus (St. aureus) and Staphylococcus epidermidis (St. epidermidis) except marjoram oil which has low antimicrobial activity against all the tested strains. The results also showed that the most potent oil was clove which decrease biofilm of P. aeruginosa by 83%, followed by marjoram (69%), then E/S of non-irradiated maggots (66%). Whiles, biofilm was less affected by cinnamon oil and E/S of irradiated maggots by 50 % and 36%, respectively. In addition, clove oil and E/S of non-irradiated maggots affect the pre-adhered biofilm of P. aeruginosa by 57 and 45 %, respectively. Conclusion: Clove oil flowed by marjoram had anti-adherent effect on P. aeruginosa. Greater inhibition of adhesion was observed by excretions of non-irradiated lucilia sericata.
