ABSTRACT

Non-biting flies are known to traverse contaminated sites, human habitations and, by extension, food during which enteric pathogens carried from filthy sites are disseminated. Humans, knowingly or unknowingly, ingest such pathogens with food, especially in cases of fresh foods. This study was conducted to elucidate the presence, prevalence and transmission rate of human enteric parasites from contaminated sites in Ile-Ife. Non-biting flies were caught with insect sweep nets from abattoirs, garbage piles, fresh food markets and public latrines between December 2014 and May 2015. Each fly, having been identified, was placed in vial half-filled with normal saline and rocked gently to dislodge the externally attached organism after which it was subsequently dissected to remove the gut content. These were examined under light microscope. 1083 flies were caught, out of which 124 were found with at least one human intestinal parasite. Abattoirs recorded the highest number of infected flies (14.34%). Nine human intestinal parasites were recorded. Entamoeba coli (32.33%) was most prevalent followed by Ascaris lumbricoides (15.79%). Garbage piles had the highest number of flies (324) while public latrines had the highest transmission rate, (19.76%). The difference between the number of parasites retrieved from the body surface and gut content was found statistically significant.

Key words: Bionetwork, Human, Intestine, Parasite, Non-Biting Flies.
