To determine the baseline Widal titres in apparently healthy children in Davangere.
Cross-sectional study was done on 250 children. Widal titers were found using tube agglutination test.
Out of 250,64.2% had a titre of less than 1:20,22.4% had a titre equal to 1:20,9.6% had a titre of 1:40 and 3.6% had a titre of 1:80 to 'O' antigen and 67.2% had a titre of less than 1:20, 21.2% had a titre equal to 1:20, 8% had a titre of 1:40 and 3.6% had a titre of 1:80 to 'H' antigen of S. enterica subsp. enterica ser. Typhi. No children in age group 6 months-2 years had a titre of 1:80 to either antigen. All children in this age group had a titre of less than 1:20 to AH antigen and older children had a titre upto 1:40 dilution.
Baseline titres for either S. enterica subsp. enterica ser. Typhi antigen in 6 month-2 year was 1:40 and older children was 1:80. Baseline titres for H antigen of S. enterica subsp. enterica ser. Paratyphi A in 6 month-2 year was less than 1:20 and for older children was 1:40 dilution.
确定达万盖尔地区表面健康儿童的维达试验基线滴度。
对250名儿童进行横断面研究。采用试管凝集试验检测维达试验滴度。
在250名儿童中，64.2%的儿童“O”抗原滴度低于1:20，22.4%的儿童滴度等于1:20，9.6%的儿童滴度为1:40，3.6%的儿童滴度为1:80；67.2%的儿童“H”抗原滴度低于1:20，21.2%的儿童滴度等于1:20，8%的儿童滴度为1:40，3.6%的儿童滴度为1:80。6个月至2岁年龄组的儿童两种抗原的滴度均未达到1:80。该年龄组所有儿童的“A、H”抗原滴度均低于1:20，年龄较大儿童的滴度最高为1:40稀释度。
6个月至2岁儿童中，肠炎沙门氏菌伤寒亚种的两种抗原基线滴度为1:40，年龄较大儿童为1:80。6个月至2岁儿童中，肠炎沙门氏菌甲型副伤寒亚种“H”抗原基线滴度低于1:20，年龄较大儿童为1:40稀释度。
