Salmonella is a genus of gram-negative Enterobacteriaceae – commonly implicated in foodborne illness and the causative agent of typhoid and paratyphoid fever. Salmonella species have been isolated from humans and animals. More than 2000 serovars of Salmonella exists with each showing different host specificities. For example, humans are the only known natural reservoir for serotype Salmonella Typhi and serotypes Salmonella Paratyphi A, B and C. The organism can be transmitted by the faecal-oral route. It is excreted by humans in faeces and may be transmitted by contaminated water, food, or by person-to-person contact (with inadequate attention to personal hygiene).
