The relationship between rickettsia-like-organisms and trypanosome infections in natural populations of tsetse in Liberia.
A survey of natural populations of tsetse flies for rickettsia-like-organisms (RLO) has been carried out in Liberia. A population of G.p. palpalis showed a strong association between trypanosome and RLO infection; both infections were at low levels in this species suggesting that this population is highly refractory to trypanosome infection. A small sample of G. nigrofusca, considered the most effective vector of trypanosomiasis in Liberia, was found to have very high prevalence of RLO infection. The selection pressures which could determine RLO infection rate are discussed.
