{{SK}} Enteric fever.
:''This about the disease paratyphoid fever. See [[typhus]] for an unrelated disease with a similar name. [[Typhoid fever]] is a related disease but is caused by a different bacteria.''
'''Paratyphoid fevers''' or '''Enteric fevers''' are a group of enteric illnesses caused by strains of the [[bacterium]] ''[[Salmonella paratyphi]]''.
There are three species of ''Salmonellae'' that cause paratyphoid: ''Salmonella paratyphi A'', ''S. paratyphi B'' ( or ''S. schotmulleri'') and ''S. paratyphi C'' (''S. hirschfeldii'').  


They are transmitted by means of contaminated water or food.
==[[Paratyphoid fever overview|Overview]]==


The paratyphoid bears similarities with typhoid fever, but its course is more benign.
==[[Paratyphoid fever historical perspective|Historical Perspective]]==


==Paratyphoid A==
==[[Paratyphoid fever classification|Classification]]==
Infections with ''S. Paratyphi A'' are common in Africa, they follow a course similar to typhoid but [[rose spots]] are more abundant and larger.


Diagnosis is made on the base of blood and stool cultures and the results of [[Widal test]] (aglutinnins anti AH).
==[[Paratyphoid fever pathophysiology|Pathophysiology]]==


Paratyphoid A usually responds well to [[chloramphenicol]] or [[co-trimoxazole]] therapy but relapses are frequent.
==[[Paratyphoid fever causes|Causes]]==


==Paratyphoid B==
==[[Paratyphoid fever differential diagnosis|Differentiating Paratyphoid fever from other Diseases]]==
Paratyphoid B is more frequent in Europe. It can present as a typhoid like illness, as a severe gastroenteritis or with features of both. [[Herpes]] labialis, rare in true typhoid fever, is frequently seen in Para B.


Diagnosis is with isolation of the agent in blood or stool and demonstration of antibodies anti BH in the [[Widal test]].
==[[Paratyphoid fever epidemiology and demographics|Epidemiology and Demographics]]==


The disease responds well to chloramphenicol or co-trimoxazole.
==[[Paratyphoid fever epidemiology and demographics|Risk Factors]]==


==Paratyphoid C==
==[[Paratyphoid fever natural history|Natural History, Complications and Prognosis]]==
Paratyphoid C is a rare infection, generally seen in the Far East. It presents as a [[septicaemia]] with [[metastasis|metastatic]] [[abscess]]es. [[Cholecystitis]] is possible in the course of the disease.


[[Antibody|Antibodies]] to para C are not usually tested and the diagnosis is made with blood cultures.
