An in vitro infectivity assay was used to examine five cryoprotectants for their suitability of preserving Theileria parva sporozoites. All five were capable of preserving T. parva sporozoites through freezing, the optimal concentrations being 7.5 percent for glycerol, 5 percent for dimethyl sulp...

The effects of holding temperature, pH and medium on the infectivity of Theileria parva sporozoites were investigated using an in vitro infectivity assay. The sporozoite infectivity lasted for 72 h at a holding temperature of 4 C but for only 24 h at 24 degrees C. Sporozoite infectivity was fo...

Polymerase chain reaction (PCR) and deoxyribonucleic acid (DNA) probes were used to characterize trypanosomes from cattle in Morogoro region of Tanzania. Blood samples collected from 390 beef and dairy cattle in selected farms in Morogoro region were examined for presence of trypanosomes using th...
