In a single generation of selection, two lines of Glossina morsitans centralis were established that differed significantly in susceptibility to Trypanosoma congolense clone IL 1180. Reciprocal crosses demonstrated that susceptibility was a maternally inherited trait. Differences between the line...
In field studies, tsetse flies (Diptera: Glossinidae) feed more successfully on cattle infected with Trypanosoma congolense Broden (Kinetoplastida: Trypanosomatidae) than on cattle infected with T. vivax Ziemann or uninfected cattle. Here we describe the first laboratory investigation of this phe...
The trypanosome surface coat is composed almost entirely of a homogeneous array of molecules known as variable surface glycoproteins (VSG). These molecules are highly immunogenic and elicit a strong antibody response in the infected host. Antibodies against the surface-exposed epitopes of a parti...
The effects of trypanosomiasis and production of zebu, N'Dama and Muturu cattle in tse-tse infested areas are investigated. Observations on parasitaemia, blood values, body weight and clinical condition included. The zebu, N'Dama and Muturu cattle showed relative resistance to infection with try...
To determine the duration after treatment of cattle with diminazene aceturate that the drug influences the tsetse infectivity and transmissibility of a drug-resistant Trypanosoma congolense, six Boran cattle were infected with T. congolense IL 3338 via the bites of Glossina morsitans centralis. A...
