Abstract :

Background: Enteric fever is a systemic infection that is caused by a salmonella serotypes. Widal test is widely used laboratory test for diagnosis of enteric fever especially where culture facilities are not available. Aims and Objectives: To establish the presumptive and diagnostically significant titre for the diagnosis of enteric fever. Material and method: Study was conducted on 250 healthy individuals. Widal titre was estimated by tube agglutination test for O, H, AH and BH antibodies. Result: From 250 sera tested, 209 sera showed presence of agglutinins to one or more antigens while remaining 41 sera didn�t show the presence of agglutinins. Conclusion: In Jamnagar city area Widal agglutination titre cut off level for the presumptive diagnosis of enteric fever against S. typhi is > 1:80 for anti �O� and �H�, S. paratyphi A is > 1:30 for anti �AH�, S. paratyphi B is > 1:20 for anti �BH�.
