Genome analysis of Salmonella strains isolated from imported frozen fish in Burkina Faso
Abstract Purpose Fish is an excellent source of protein and vitamins for humans, but improperly handled, fish can expose consumers to pathogenic bacteria. This study was aimed to isolate and characterize the genomes of Salmonella strains isolated from imported fish sold in the open market in Ouagado...
