Clinical Application of a Dot Blot Test for Diagnosis of Enteric Fever Due to Salmonella enterica Serovar Typhi in Patients with Typhoid Fever from Colombia and Peru

Clinical application of a dot blot test to detect immunoglobulin G (IgG) (88% sensitivity and specificity) and IgM (12.1% sensitivity and 97% specificity) against flagellar antigen from Salmonella enterica serovar Typhi was performed in Peruvian and Colombian patients with typhoid fever. This test can be used as a good predictor of serovar Typhi infection in regions lacking laboratory facilities and in field studies.
