Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. [1] It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general), these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food.
Without treatment, symptoms may last weeks or months. [5] Diarrhea may be severe, but is uncommon. [7] Other people may carry it without being affected, but are still contagious. [8] Typhoid fever is a type of enteric fever, along with paratyphoid fever. [2] Salmonella enterica Typhi is believed to infect and replicate only within humans. [9]
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.
The chlorination of public drinking water led to the sharp reduction of typhoid in developed nations. [8] In typhoid-endemic countries, Typhoid vaccines have been shown to prevent 40 to 90% of cases during the first two years, [ 9 ] and may have some effect for up to seven years.
Paratyphoid fever, also known simply as paratyphoid, is a bacterial infection caused by one of three types of Salmonella enterica. [1] Symptoms usually begin 6–30 days after exposure and are the same as those of typhoid fever. [1] [3] Often, a gradual onset of a high fever occurs over several days. [1]
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 ...
Complications of the disease often appear as anemia or septicaemia, and the mortality rate is 15% once these symptoms arise. [ 13 ] The serogroup S. Typhi is the cause of typhoid fever .
These fevers occur following infection by Salmonella typhi and Salmonella paratyphi respectively. Rose spots may also occur following invasive non-typhoid salmonellosis. Rose spots are bacterial emboli to the skin and occur in approximately 1/3 of cases of typhoid fever. They are one of the classic signs of untreated disease, but can also be ...
