Abstract

Necator americanus and Ancylostoma duodenale are the 2 major species of human hookworms occurring in Sub-Saharan Africa. Up to date, without any hookworm species identification study, Necator americanus remains the only species reported in Cameroon. In order to identify hookworm species from two Health Districts in Cameroon, stool samples from ~ 100 hookworm-positive schoolchildren were cultured to the third-stage (L3), filariform larvae, using the Harada-Moritest-tube method. In the Health District of Mouanko, N. americanus larvae were recovered from a total of 27 (62.79%) coprocultures while A. duodenale larvae were recovered from a total of 24 (55.81%) stool cultures. 44.18% of the hookworm infections were due solely to N. americanus, 37.2% solely to A. duodenale and 18.6% were mixed infections with both species. In all mixed infections, N. americanus appears to be the predominate species. In contrast, in the health district of Loum, N. americanus larvae were the only species found in all of the20 hookworm-positive coprocultures. This study reports for the first time the presence of A. duodenale in Cameroon. This new data is very important because it emphasizes the need to assess the actual distribution of these two species in Cameroon, for better taken into account in treatment and control strategies.
