Six genera of bacteria: Serratia, Providencia, Enterobacter, Aeromonas, Cedecea and Bacillus were isolated from field-collected G. pallidipes. Four genera: Serratia, Providencia, Enterobacter and Aeromonas were isolated from insectary-reared Glossina morsitans morsitans. All bacteria except, Bacillus spp. and Providencia alcalifaciens were pathogenic for teneral G. m. morsitans. Bacteria isolated from insectary-reared tsetse were more pathogenic than those isolated from the field. Fungi of three genera were also isolated from field-collected adult G. pallidipes, Penicillium, Aspergillus and Fusarium. Five genera, Aspergillus, Penicillium, Rhizopus, Mucor and Trichoderma were isolated from field-collected G. pallidipes pupae. The fungi, however, were only mildly pathogenic for adult tsetse and were not pathogenic for pupae.
