Rose spots on the abdomen of a man with typhoid fever. Paratyphoid fever resembles typhoid fever. Infection is characterized by a sustained fever, headache, abdominal pain, malaise, anorexia, a nonproductive cough (in early stage of illness), a relative bradycardia (slow heart rate), and hepatosplenomegaly (an enlargement of the liver and ...
Typhoid fever, also known simply as typhoid, is a disease caused by Salmonella enterica serotype Typhi bacteria, also called Salmonella typhi. [ 2 ] [ 3 ] Symptoms vary from mild to severe, and usually begin six to 30 days after exposure.
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.
Intestinal infectious diseases include a large number of infections of the bowels, including cholera, typhoid fever, paratyphoid fever, other types of salmonella infections, shigellosis, botulism, gastroenteritis, and amoebiasis among others. [1] Typhoid and paratyphoid resulted in 221,000 deaths in 2013 down from 259,000 deaths in 1990. [2]

Rose spots are blanching red macules 2-4 millimeters in diameter occurring in patients with enteric fever (which includes typhoid and paratyphoid). These fevers occur following infection by Salmonella typhi and Salmonella paratyphi respectively. Rose spots may also occur following invasive non-typhoid salmonellosis.
These organisms produce H 2 S from thiosulfate and can be identified easily on differential media such as bismuth sulfite agar. [2] [3] [4] Typhidot is the other test used to ascertain the diagnosis of typhoid fever. A new serological test called the Tubex test is neither superior nor better performing than the Widal test.
Typhoid fever is caused by Salmonella serotypes which are strictly adapted to humans or higher primates—these include Salmonella Typhi, Paratyphi A, Paratyphi B, and Paratyphi C. In the systemic form of the disease, salmonellae pass through the lymphatic system of the intestine into the blood of the patients (typhoid form) and are carried to ...
