Salmonella typhi is a gram-negative bacterium that can infect the gastrointestinal tract and the blood causing a disease commonly known as typhoid fever. Symptoms of infection often include high fever, fatigue, and headache, loss of appetite, constipation, or diarrhea.
Infection is mostly gotten through consumption of contaminated food and water. Vi antigen co agglutination is used to detect the presence of Salmonella typhi Vi antigen in the blood. This test shows a high level of sensitivity and specificity when compared with blood culture or widal titer test. It can be done to confirm the diagnosis of Salmonella typhi.
