Abstract

Two human hookworm species (Ancylostoma duodenale and Necator americanus) are endemic in many rur;l_ communities in the tropics causing human hookworm diseases. Both species are usually reported in routir. diagnosis as 'hookioorm eggs' without recourse to their speciation. Stool samples from 297 individuals wifF hookworm eggs were cultured at four varying temperatures to the third stage infective filariform (L3) larvae, using the Harada-Mori filter paper strip culture technique. A. duodenale (61.0%) alone recorded higher prevalence c~ hookworm infection than N. americanus (25.9%) and cases of mixed infection with both species (13.1%). Roc— temperature (30.5°C) gave the optimum temperature for the development of both species of hookworm at seven dayz post-incubation period. The study highlights the influence of temperature and numbers of days on the developer. and prevalence of hookworm infection in the studied communities in Nasarawa State, Nigeria. These findings oversimplification hookworm transmission and control in the area.
