Profile of potentially pathogenic intestinal parasites and bacterial agents in solid wastes in Ibadan municipality

O.A Adeyeba, J.A. Akinbo



In order determine the profile of potentially pathogenic enteric parasites and bacterial agents inmunicipal refuse dumps in Ibadan, 5 major market places in the city were randomly selected by balloting method. Refuse sludge were examined parasitologically and bacteriological using the method described. The data analysis was done and test of significance carried out by using the chi square test where applicable.
Cases of multiple parasites and bacterial agents were commonly encountered in the sludge refuse samples. The commonly found parasitic agents were of both human and veterinary importance. These included Ascaris lumbricoides (9.3 epg), Entamoeba histolytica (8,07 cyst per gram); Hookworm/strongyle (6.27 epg) and Ascaris suum (1.07 epg). Others are Ascaris vitolorum (1.09 epg) Stongyloides papillosu (0.52 larvae/g) Schistosoma suis (0.31 epg) and Dicrocoelium dendriticum whilst the most commonly found bacterial agents were Klebsiella species, Escherichia coli, Proteus specie, streptococci and other gram-positive organisms. Climatic conditions affected the distribution of both parasites and bacterial agents in the sludge (P<0.001). more intestinal parasites (53.4%) and bacterial agents (27.2%) were encountered at mean air temperature 26.1 0.60C, mean relative humidity of 72 3.5%. The degree of contamination by market location varies significantly (P<0.001) A high degree of contamination of solid waste dumpsites with bacterial and bacterial and parasitic agents was observed in the present study. As a result of the public importance of the organisms isolated it is opined that well planned waste management and health education programs will go a long way to reduce the potential epidemic risks posed by such sites in Ibadan, Nigeria. it is believed that economic advantage could be taken of the mountainous solid waste dump by establishing fertilizer-processing plant to produce fertilizer for farmers and provide job opportunity for youths in the area.
