A combined field and laboratory investigation was conducted on the bionomics of geohelminths in contaminated foci in Abua communities using the Cobb’s decanting and sieving method. The result of the study showed that eggs of
Ascaris lumbricoides were 262 (44%), hookworm, 173 (29%) and
Trichuris trichiura
, 102 (17%). The larvae of hookworm recovered were 323(54%) and no larvae of
Ascaris and
Trichuris were recovered. Combination of eggs and larvae recovered from the study, showed that hookworm larvae were 496 (83%),
Ascaris eggs, 317 (53%), and Trichuris eggs, 102 (17%). It was observed that hookworm eggs and larvae were the most abundant, followed by
Ascaris eggs and
Trichuris eggs. The result of the study was statistically significant at 0.05% level (f-test = 6. 957, p>0.05). The above indicates that the occurrence of these geohelminths was dependent on the contaminated foci with human faeces. The implication of this, is that human population in the study area should be discouraged from passing out faeces at common spots, considering the health hazard and other complications arising from geohelminth infections.@ JASEM
