Dr. Shikongo-Nambabi is a Namibian with over twenty years of experience in the field of Microbiology education, research and diagnostics in Namibia. She has been engaged in lecturing Microbiology for the past 10 years. Prior to this Dr. Shikongo-Nambabi worked as a veterinary diagnostician at the Central Veterinary laboratory in Windhoek, Namibia and later on in Food and feed quality analysis and certification. She worked as the national focal point for biosafety and she is a co-founder of the Namibian Biotechnology alliance. She is currently involved in the research project for indigenous fermented foods and beverages quality determination. |
Martha Naita Namwaala Nangulohi Shikongo-Nambabi was born and grew up in Ombalanthu, Namibia. She received her lower primary education at Onangholo and higher primary school at Tsandi, Omusati region, Namibia. She attended lower secondary school at Ongwediva college, Namibia and high secondary school at the Federal Government Girls College, Owerri, Nigeria where she matriculated in 1979. From 1980-1984 she taught science at SWAPO health and education centres in Cuba, Nyango Zambia and Kwanza-Sul, Angola. She was awarded a B Sc (Honours) degree, Biochemistry in 1988 by Kent University, UK and MSc degree in Applied Immunology in 1990 by Brunel University of West London. She is currently a lecturer in Microbiology at the University of Namibia.
In her thesis entitled, Occurrence and control of Vibrio spp. as contaminants of processed marine fish, she studied the extent and source of contamination of hake, fish harvested from Namibia. The study has shown that the microbiological quality indicators in hake are within acceptable limits; however contamination with Vibrio species originating from chlorinated and UV irradiated sea water occurred during processing. The predominant bacteria were Vibrio alginolyticus. Using a bench-top laboratory scale unit she demonstrated that the isolated V. alginolyticus strains were able to form biofilms in artificial sea water that cannot be controlled using chlorine or ozone. She however found that hydrogen peroxide was effective in inhibiting both biofilm formation and mature biofilms formed by the isolates at concentration that might not negatively impact on the sensory quality of processed hake. This research has produced two publications in peer reviewed journals and one in a Symposium proceeding. The research serves as a stepping stone towards developing efficient disinfection methods tailor made for sea water. Potable sea water is an absolute necessity during processing in the fishing industry in Namibia that is often faced with severe fresh water shortage |
