Background & Objective: Typhoid fever still continues to be a major public health problem around the world. A simple, reliable and affordable rapid diagnostic test has been a long felt need of the clinicians. We therefore prospectively evaluated the sensitivity and specificity of Typhidot test.
Methods: The study was carried out between January 2002 and December 2003, on a total of 563 samples from patients clinically suspected to have typhoid fever; blood culture as well as serum for Typhidot test were received.
Results: Of the 563 samples, Typhidot test and blood culture were positive in 36 patients, both the tests were negative for 503 patients. Typhidot test was positive for 9 patients with S. Paratyphi A infection. The sensitivity and specificity of the test using blood culture as gold standard were 92.3 and 98.8 per cent respectively for the typhoid fever.
Interpretation & Conclusion: Typhidot test is rapid, easy to perform and reliable test for diagnosing typhoid fever, useful for small less equipped laboratories as well as for those with better facilities.

Salmonella is an enteric pathogenic bacterium in mammals that thrives in sewage, soil, and aquatic environments because of its wide ecological adaptability. The spread of Salmonella infection is associated with a lack of clean water, poor hygiene, and poor sanitation in developing countries. However, the input of Salmonella-contaminated surface water and groundwater in the environmental dissemination of antimicrobial-resistant Salmonella is obscure outside developed countries.
