Role of Sickle-Cell Trait, Malaria and Epstein Barr Virus Coinfection On Ebna-L-Specific T-Cell Immunity in the Etiology Of Endemic Burkitt Lymphoma in Children Aged 4-9 Years From Western Kenya
(Maseno University, 2013)Etiological mechanism underlying endemic Burkitt lymphoma (eBL), remain unknown despite the long-standing epidemiological link between Plasmodium Jalciparum and Epstein Barr Virus (EBV) co-infections. Although past studies ... -
Validation of A Cytometric Multiplex Assay and Examination Of Antibody Responses to Plasmodium Falciparum Antigens in the Highlands of Western Kenya During a Period of Low Malaria Transmission
(Maseno University, 2013)Malaria is one of the world's most deadly diseases. Even though it is highly preventable and treatable, it is a leading cause of morbidity and mortality in the tropics. As the campaign for malaria eradication widens, ... -
Determination of Antimicrobial Resistance of Escherichia Coli Isolated From Rastrineobola Argentea and Water Samples From Lake Victoria - Kenya
(Maseno University, 2014)Many strains of Escherichia coli can be pathogenic leading to diarrheal diseases. The occurrence of antimicrobial resistant bacteria is increasing in aquatic environments infecting fish which are later consumed by humans ... -
