Enteric fever is a medical term encompassing two types of salmonellosis, which, specifically, are typhoid fever and paratyphoid fever.[1] Enteric fever is a potentially life-threatening acute febrile systemic infection and is diagnosed by isolating a pathogen on culture.[1][copyright violation] Typhoid fever is caused by the Salmonella enterica bacteria, serotype typhi, while paratyphoid fever is caused by the Salmonella enterica bacteria, serotype paratyphi A, B, or C.[1] These Salmonella enterica bacteria serovars that cause enteric fever only have human hosts, as opposed to other types of salmonellosis-causing Salmonella bacteria which often have animal reservoirs.[2]
