The current study investigated the effects of different types of Kenyan tea extracts on the pathogenesis of Trypanosoma brucei brucei in a Swiss White mice model. Following infection with trypanosomes, the mice were monitored for survival and liver pathology. Tea significantly (P<0.05) enhanced the survival rate of tea treated mice. Additionally, in tea treated but infected mice, there was reduction in infiltration of inflammatory cells into the periportal and parenchymal regions as well as hepatocyte cell damage compared to the infected untreated animals. Green and white teas were superior in most of the above effects while black tea and oolong teas had the least effects. The tea extracts were more efficacious than dexamethasone in prolonging the life... |

Clinical and pathological characterisation of blood stream (BSF) and cerebrospinal fluid (CSF) forms of Trypanosoma brucei rhodesiense trypanosome isolated from a sleeping sickness patient were investigated in rabbits. The study aimed at investigating whether there is any significant difference in clinical and pathological presentation in rabbits infected by the two forms of trypanosomes. Each form of parasite was inoculated into five rabbits at 104 trypanosomes/ml while five rabbits were used as un-infected controls. Parasitaemia development, body temperature, packed cell volume (PCV), body weight, food and water intake, heartbeat and respiration were monitored daily for 30 days post infection when the experiment was terminated. Pathological changes were... |
