These lineages are restricted to West Africa, where they cause up to half of human pulmonary tuberculosis. In this review we discuss the definition of M. africanum, describe the prevalence and restricted g...
The African lion has declined to <35,000 individuals occupying 25% of its historic range. The situation is most critical for the geographically isolated populations in West Africa, where the species is considered regionally endangered.

Plasmodium falciparum malaria poses an increasing risk to travellers to West Africa. The development of chloroquine resistant in West Africa has further compounded the risk. Two cases of falciparum malaria from Sierra Leone are presented. One represents the classic missed case and the other a probable case of chloroquine resistant (RI vide infra) falciparum malaria. These cases highlight the da...
