Theileria parva has been shown to infect and transform B cells and T cells at similar frequencies in vitro. However, the majority of parasitized cells in the tissues of infected cattle are alpha/beta T cells. The aim of this study was to determine whether the cell type infected with T. parva infl...

Four Trypanosoma (T.) congolense reference clones with known isometamidium sensitivity and 16 T. congolense stocks from cattle in Kenedougou in south-western Burkina Faso, an area with known history of drug resistance, were characterised with the standard mouse test (SMT) and the drug incubatio...

Aphids are regarded as important pest problems of vegetable crops worldwide. Most vegetable growers in sub-Saharan Africa heavily rely on synthetic chemical insecticides for aphids’ control. Fungus-based biopesticides are being considered as alternatives to chemical insecticides. This study evalu...

The present work aims to assess the pathogenicity of the conidia of six isolates of Metarhizium anisopliae and two isolates of Beauveria bassiana on Helicoverpa armigera in order to select the most promising ones for developing a microbiological product to be used in cotton fields. The pathogenic...

Pseudocercospora fijiensis, causal agent of the black Sigatoka disease (BSD) of Musa spp., has spread globally since its discovery in Fiji 1963 to all the banana and plantain growing areas across the globe. It is becoming the most damaging and economically important disease of this crop. The iden...

A total of 18 bean var. with different degrees of rust resistance in the field were subjected to 4 treatments, to obtain high severity of Uromyces phaseoli under low RH. Treatments were (1) greenhouse inoculation, with optimum temp. and RH for disease development, (2) field inoculation in infecti...
