Laboratoire Sion| Cameroon
Dr. Ngouana Kammalac Thierry is an accomplished Cameroonian biochemist and medical mycologist with extensive experience in microbial diagnostics, infectious disease research, and biotechnology innovation. He holds a PhD in Biochemistry and Health Sciences (2014), jointly awarded by the University of Montpellier in France and the University of Yaoundé I in Cameroon, where his doctoral work focused on the genetic diversity of Cryptococcus and Candida isolates in HIV-positive patients and their susceptibility to antifungal therapies and medicinal plant extracts. He also holds a Master’s degree in Biochemistry (2009) from the University of Yaoundé I. Dr. Ngouana has built an exceptional career at the intersection of laboratory science, diagnostic technology, and academic instruction. As Director of Zion Biomedical Corporation since 2023, he leads the development and large-scale production of innovative biomedical products, including lateral flow immunochromatographic diagnostic tests, microbial culture media, and specialized staining dyes, contributing to improved diagnostic capacities in the region. Since 2016, he has also served as Director of Zion Medical Laboratory, where he oversees scientific development, clinical diagnostics, and antimicrobial resistance surveillance. His laboratory plays a crucial role in cryptococcal meningitis diagnosis among HIV-infected patients, the establishment of microbial standard operating procedures (SOPs), and the strengthening of Cameroon’s diagnostic infrastructure. Alongside his laboratory leadership, Dr. Ngouana has been an associate lecturer at the Catholic University and the Protestant University of Central Africa since 2015, teaching courses in medical mycology, biochemistry, and bacteriology. He has a strong publication record, contributing to high-impact research on Candida genetic diversity, antifungal resistance, pathogenic yeast epidemiology, and bioactive compounds from medicinal plants. His work has appeared in reputable journals such as Brazilian Journal of Microbiology, American Journal of Microbiological Research, Mycoses, Journal de Mycologie Médicale, Medical Mycology, and Journal of Medical Microbiology. Notable contributions include studies revealing novel genotypes of Candida species, antifungal susceptibility patterns in Africa and Europe, and plant-derived compounds with potent antifungal activity. Dr. Ngouana’s expertise spans molecular diagnostics, PCR, microscopy, microbial culture, infection control, and data analysis, supported by strong research methodology and teamwork competencies. He is an active member of the FAILSAFE Medical Mycology Network, the Cameroonian Society of Microbiology, and the French Society of Medical Mycology, reflecting his engagement in global scientific collaboration and capacity building in medical mycology.
