Anthony Smith

Dr. Anthony Smith is a Lecturer in Clinical Microbiology and Infectious Diseases at the University of the Witwatersrand, Faculty of Health Sciences. He also holds a joint appointment as Senior Research Officer at the same institution and serves as an Extraordinary Professor at the University of Pretoria. He is a Principal Medical Scientist at the Centre for Enteric Diseases (CED), National Institute for Communicable Diseases (NICD), Johannesburg, with 35 years of service. His work bridges clinical microbiology, genomic surveillance, and public health policy.

Research Interests: Dr. Smith's research focuses on infectious and enteric diseases, particularly the molecular epidemiology and antimicrobial resistance of bacterial pathogens such as Salmonella, Shigella, E. coli, Listeria, and Vibrio cholerae. He applies advanced techniques including PCR, whole-genome sequencing, and metagenomics for outbreak investigations and surveillance. His work often adopts a One Health approach, integrating human, animal, and environmental health perspectives.

Recent Research Trends: His recent publications (2023–2025) highlight a strong emphasis on genomic epidemiology of enteric pathogens, antimicrobial resistance surveillance in clinical and environmental settings, and the use of digital tools like the TyphiNET dashboard for public health decision-making. His studies span South Africa and extend to regional contexts in Africa, including Zambia and Madagascar, reflecting a broad public health impact.

Scientific Recognition:

• National Research Foundation (NRF) B2 rating, South Africa

Advising and Grants: Dr. Smith supervises 8 PhD and 17 MSc students and mentors intern medical scientists. While specific grants are not listed, his extensive publication record in high-impact journals and leadership in national and international surveillance networks (e.g., PulseNet International) suggest sustained research funding and collaborative support.

Labs and Teams: He is a key member of the Centre for Enteric Diseases (CED) at NICD, a national reference laboratory for enteric pathogens. He also contributes to PulseNet International, a global network for molecular subtyping of foodborne pathogens, and leads genomic investigations into major public health outbreaks in South Africa.
