Leprosy, a chronic human disease with potentially debilitating neurological consequences, results from infection with Mycobacterium leprae. This unculturable pathogen has undergone extensive reductive evolution, with half of its genome now occupied by pseudogenes. Using comparative genomics, we demonstrated that all extant cases of leprosy are attributable to a single clone whose dissemination ...
Introduction: Accurate information on farmer and consumer behavior is the foundation for identifying public investments and policies that can effectively promote national food security and income growth objectives. This policy brief summarizes recent findings from a study on smallholder crop marketing behavior and urban consumption patterns in Eastern and Southern Africa. The full report is dow...
Genetic characterization of highly pathogenic avian influenza viruses (H5N1) isolated in July 2008 in Nigeria indicates that a distinct genotype, never before detected in Africa, reached the continent. Phylogenetic analysis showed that the viruses are genetically closely related to European and Middle Eastern influenza A (H5N1) isolates detected in 2007.
Setaria africana (Yeh, 1959) is represented by two subspecies, Setaria africana africana Troncy, Graber & Thal, 1976 from giant eland (Taurotragus derbianus) from the Central African Republic and Cameroon and Setaria africana farchai Troncy, Graber & Thal, 1976 from bushbuck (Tragelaphus scriptus), also from the Central African Republic. Material collected from nyala (Tragelaphus angasii), bush...
