Colour change is a common physical phenomenon observed during drying, which need to be controlled since it directly affects consumer acceptance of dried products. This study aimed to investigate the feasibility of using computer vision, combined with laser light backscattering analysis at 650 nm ...
Approximately 320 East African Zebu cows over 36 months of age were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cows were individually treated with diminazen...
The sensitivity of seven populations of T. congolense to the salts of three trypanocides, diminazene, isometamidium and homidium, were determined in vitro using in vitro-derived metacyclic trypanosomes. The trypanosomes were incubated at 35 degree centigrade for 48 hours with various drug concent...
A modified NC membrane-based dot-ELISA was used to detect and differentiate between Trypanosoma brucei, T. congolense and T. simiae procyclics in the midguts of experimentally infected tsetse flies. The modification of the assay consisted of (a) the lysis of T. congolense or T. simiae in NC membr...
Tsetse fly populations have been monitored since January 1986 in two areas of the Ghibe valley in southwest Ethiopia, in order to assess trypanosomiasis risk to cattle. The two study areas are Abelti/Ghibe and Gullele/Tolley. Two species of tsetse fly were detected in the valley from 1986 to 1992...
An isolate of T. vivax was collected from a naturally infected Zebu in French Guyana. The isolate was subsequently shown to produce pathogenic infections in both Taurine and Zebu cattle. However, its sensitivity of the population to diminazene aceturate and isometamidium chloride was determined s...
