Summary Objective To evaluate Trypanosoma brucei gambiense infection in peri‐domestic livestock from Kogo and Mbini foci (Equatorial Guinea) in order to investigate its possible implication in the sleeping sickness transmission cycle in these hypoendemic foci. Methods Samples from 698 domestic animals (goats, sheep and pigs) from trypanosomiasis‐endemic localities of Kogo and Mbini foci were tested for animal trypanosomes and T. b. gambiense (group I) by species‐specific polymerase chain reaction. Results Trypanosoma brucei s.l., the predominant trypanosome species, was detected in 182 (52.6%) samples from Mbini and in 127 (36.1%) samples from Kogo. T. b. gambiense was only identified in seven (2%) of the Mbini samples and one co‐infection (with T. vivax ) was observed. Conclusion The occurrence of T. b. gambiense in peri‐domestic livestock in Mbini and its absence in Kogo could explain the epidemiological differences between the two foci and could have significant implications for sleeping sickness control in Equatorial Guinea.
