ABSTRACT
This study was carried out to isolate and identify the microbial load of the external body surfaces of houseflies (Musca domestica) and cockroaches (Periplaneta americana) from different locations such as; public toilet, Ubani market, refuse dumps, hostels, residential homes, broken sewages and hospitals in Umuahia, Abia state. A total of 80 houseflies and 58 cockroaches were collected from this sites and their external body parts screened for bacterial, fungal and parasitological carriage. The samples collected was prepared by placing them in sterile universal containers containing normal saline and shaking vigorously. The isolates obtained from the samples inoculated on culture plates were identified and characterized by their morphology, microscopic appearance and biochemical reaction. The most common bacterial isolates from the houseflies analyzed were E.coli (22.29%) and Klebsiella species (16.59%) while that of the cockroaches were E. coli (20.34%) and also Klebsiella species (17.37%). Aspergillus species was the most prevalent fungal group from both houseflies and cockroaches with relative abundance of (36.95%), (33.16%) respectively. Quantitative analysis of the total viable count of the bacterial and fungal isolates from both samples from the different sites revealed that the isolates obtained from the public toilets, refuse dumps and broken sewages were high as compared to those from the other sites. Parasitological investigations revealed the preponderance of Entamoeba histolytica (30%) from the houseflies’ analyzed while Ascaris lumbricoides assumed a high value in the cockroaches analyzed with a relative abundance of (35.87%). This results indicates that houseflies and cockroaches are possible reservoir of several microorganisms vie their body which could be pathogenic to man.
