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.
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.
Other means of diagnosing Salmonella typhi (and paratyphi) include cultures of blood, urine and faeces. 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 ...
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.
Salmonella bongori was previously considered a subspecies of S. enterica, but it is now the other species in the genus Salmonella. Most of the human pathogenic Salmonella serovars belong to the enterica subspecies. These serogroups include S. Typhi, S. Enteritidis, S. Paratyphi, S. Typhimurium, and S. Choleraesuis.
Salmonellosis caused by Salmonella enterica (serovar Typhimurium) has also been described as a cause of bacillary dysentery, [citation needed] though this definition is less common. It is sometimes listed as an explicit differential diagnosis of bacillary dysentery, as opposed to a cause.
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.
Salmonellosis is induced by infection of Salmonella with a swift onset of disease 12 to 36 hours after consumption of contaminants and can be clinically classified into three types, namely enteric fever (also Typhoid fever), gastroenteritis and sepsis. [7] Enteric fever usually has 7 to 14 days of incubation with mild symptoms like malaise and ...
