Episode 50: Atypical invasive non-typhoidal Salmonella in The Gambia
👥Guests
The microbinfie podcast explores invasive non-typhoidal Salmonella (iNTS) research in The Gambia, highlighting genomic approaches to understanding pathogen diversity and public health challenges in sub-Saharan Africa.
Invasive non-typhoidal Salmonella (iNTS) presents a significant public health challenge in Africa. To gain insights into this pressing issue, we spoke with Abdoulie Kanteh and Grant Mackenzie about their research efforts in The Gambia, particularly their use of genomics to understand the serovars in circulation.
