Popis: To determine the antibody titre levels to typhoid/paratyphoid fever organisms among apparently healthy volunteers.Cross sectional study.General community and University Teaching Hospital.Volunteer sample of 323 apparently healthy individuals with body temperaturesor = 37.8 degrees C.Questionnaire administration to classify volunteers into three socio-economic status (SES).There were 35.29% of the apparently healthy population in Jos community with antibodies to typhoid/paratyphoid fever organisms. The presence of these antibodies were neither sex nor SES related. Normal antibody titres were up to 1:40 and 1:80 for O and H Salmonella antigens respectively. Contrary to the general belief, typhoid/paratyphoid fevers have not affected virtually everybody in Nigeria. The difference between those without previous history and those with previous history was significant (p0.05) with those in the former category having a higher percentage.For a single sero-diagnosis to have any diagnostic value in Jos community and its environs, only a four-fold rise to what has been found to be normal should be significant. This means that only titres of 1:160 and 1:320 and above for O and H antigens should be considered significant.
