Public health importance of non-biting cyclorrhaphan flies.

Abstract:

:This study was carried out to determine the role of non-biting cyclorrhaphan flies as carriers of human intestinal parasites at Woreta, northwestern Ethiopia. In total, 6530 flies were collected from four breeding sites and then examined for human intestinal parasites, mainly using the formol-ether concentration method. Fly species identified were Musca domestica (32.9%), Chrysomya rufifacies (32.6%), Musca sorbens (23%), Lucina cuprina (4.7%), Calliphora vicina (2.8%), Chrysomya bezziana (2.3%) and Wohlfahrtia magnifica (1.7%). Intestinal parasites such as Ascaris lumbricoides (36.9%), Trichuris trichiura (38.8%), hookworm (13.0%), Hymenolepis nana (0.6%), Taenia spp. (8.4%), Strongyloides stercoralis (1.7%), Entamoeba histolytica/dispar (48.1%), Entamoeba coli (24.7%), Cryptosporidium spp. (16.7%) and Giardia lamblia (10.4%) were isolated from both external and gut contents of the flies. Trichuris trichiura and A. lumbricoides among the helminths and E. histolytica/dispar and E. coli among the protozoans were the dominant parasites identified. It was observed that more parasites were isolated from gut contents than the external surfaces of the flies examined (P<0.001). Chrysomya rufifacies were found to carry more helminths than M. sorbens and M. domestica. Musca sorbens were the highest carriers of protozoan parasites followed by M. domestica and C. rufifacies. The significance of filth flies as carriers of human intestinal parasites has been highlighted.
