A method is described for calculating new infection incidence from monthly field data collected between April 1994 and February 1998 from an average of 770 Ethiopian Highland Zebu cattle maintained under traditional management in the Ghibe valley, southwest Ethiopia and exposed to a high challeng...

Ten trypanosome isolates were collected at random from cattle at Ghibe, Ethiopia, in February 1993 and all shown to be savannah-type Trypanosoma congolense. When inoculated into naive Boran (Bos indicus) calves, all 10 isolates were resistant to diminazene aceturate (Berenil), isometamidium chlor...

Control of trypanosomes in cattle, sheep and goats in endemic areas has depended largely on the use of chemotherapeutic or chemoprophylactic agents. One such agent is homidium. The normal use of homidium has been in the treatment of infections due to both Trypanosoma congolense and T.vivax in cat...

Resistance to the drugs used to control African animal trypanosomosis is increasingly recognised as a constraint to livestock production in sub-Saharan Africa. The most commonly used tests for detection of trypanocidal drug resistance are tests using mice or ruminants, but these suffer from lack ...

Two groups of five Boran (Bos indicus) cattle were infected with one of two populations of Trypanosoma congolense; one drug-sensitive (IL1180), and one drug-resistant (IL3330). The animals were then treated intramuscularly with homidium bromide at a dose rate of 1.0 mg kg - bodyweight 7 days afte...

Two enzyme-linked immunosorbent assays (ELISA) for the determination of homidium in serum of treated cattle have been developed and evaluated. One is a direct competition (Assay 1) and the other an indirect competition assay (Assay 2). Both assays are highly sensitive with a limit of detection of...

Tsetse-transmitted trypanosomosis affects cattle production over approximately 10 million km2 of Africa. In these areas, trypanocidal drugs, both prophylactic and curative, are the most widely used methods of trypanosomosis control. However, resistance of trypanosomes to the 3 trypanocidal drugs ...
