Abstract:

Typhoid fever continues to be a global health problem, with an estimated 12 to 33 million cases occurring worldwide each year. India is an endemic country; sera of particular healthy individuals contain antibodies capable of reacting to a variable titre in Widal test due to previous stimuli. It is therefore, important to establish the antibody level in the normal population by “Widal baseline titre” in a particular locality. The serum samples are processed by Widal tube agglutination test to find out the baseline Widal titre. In the 500 samples 210 samples were positive for agglutinins to Salmonella typhi, paratyphi-A and paratyphi-B. In 210 positive samples, 166(33.2%) were positive for ‘O’ agglutinin and 184(36.8%) were positive for ‘H’ agglutinins for. For paratyphi ‘AH’ agglutinin is 21(4.2%) and for paratyphi ‘BH’ agglutinin is 16(3.2%). Widal baseline titre helps in diagnosis of enteric fever as a single diagnostic tool in particular geographical area. The significant titre of the ‘O’ agglutinins and the ‘H’ agglutinins of Salmonella typhi was ≥ 1: 80. While the significant titre of the ‘H’ agglutinins of Salmonella paratyphi Awas ≥ 1: 80 and ‘H’ agglutinins of Salmonella paratyphi B was ≥ 1: 40.
