Prof. Jaffu Othniel Chilongola

Associate Professor of Medical Biochemistry and Immunology

Jaffu Chilongola is an associate professor of medical biochemistry and immunology at the Kilimanjaro Christian Medical University College, in Moshi, northern Tanzania. He holds a Doctor of Philosophy degree in molecular genetics (severe paediatric malaria), a Master of Science (Immunology) and a Doctor of Vet Medicine degree from Sokoine University, Tanzania.  Jaffu Chilongola has worked with the KCMUCo as a lecturer of medical biochemistry and immunology as well as a senior research scientist since 2006. He is involved in research on the immunology and pathogenesis of tropical infectious diseases including malaria, tuberculosis and arthropod-borne viral infections (arboviruses). In particular, his expertise is on severe malaria in children where he has worked on gene expression profiles of malaria parasites causing severe malaria in children and functional roles of P. falciparum host receptor polymorphisms (CD36 and ICAM-1) on severe malaria in children. This interest has currently expanded to include understanding the immunological, genetic, epidemiological, and transmission dynamics of neglected tropical diseases including zoonotic arboviruses–malaria confections.

Ongoing projects

  1. GAMEVAC project (Funded by the Tanzania Commission for Science and Technology-COSTECH). Several gametocyte specific peptides have been investigated and reported to be immunogenic and some have been further explored as malaria transmission blocking vaccines. Through this project, Professor Jaffu Chilongola and his team are producing gametocyte-specific peptides for the purpose of testing their potential as future vaccines and targets for a diagnostic test. The team has produced the peptides and their currently undergoing various immuno-characterization tests. It is hoped that at the end of the project, full characterization of the peptides regarding their immunogenicity, specificity, and other properties will have been defined.

  1. TransVir Project (Funded by the International Centre for Genetic Engineering and Biotechnology-ICGEB)

We are conducting comprehensive seasonal cross-sectional surveys to identify potential reservoirs of RVFV, DENV and CHIKV across the different seasons of the year. To achieve this, we will determine viral infection rates in selected ruminants, humans and Aedes mosquitoes across seasons. We will also determine recent/previous exposure to RVFV, DENV and CHIKV in domestic ruminants and humans. Linked to infection and exposure data will be meteorological data and vector abundance data as potentially important factors that affect arbovirus transmission dynamics. Data from our team will allow for development of prediction models for better outbreak prediction, identification of hotspots for targeted control of arboviruses, and inform public and animal health authorities for better concerted control measures to limit the spread of arbovirus infections.
