Projectstore - December 18, 2020. Laboratory Identification . Salmonella pathogenicity relies on virulence factors many of which are clustered within the Salmonella pathogenicity islands.Salmonella also harbours mobile genetic elements such as virulence plasmids, prophage‐like elements and antimicrobial resistance genes which can contribute to increase its pathogenicity. This facility is not available in many areas where the disease is endemic. Laboratory diagnosis of enteric fever is based on the following methods: a) Isolation of Salmonella spp. The laboratory diagnosis of Salmonella infection is mainly based on the isolation and identification of the pathogen from clinically important specimen through cultural techniques.
