| prevalence of diphtheria and tetanus antibodies in young adults in delhi. | a total of 574 blood samples collected mainly from adult males, on a random basis, were tested for diphtheria and tetanus antibodies by indirect haemagglutination (iha) test to find out the percentage of individuals with protective titres (> or = 0.015 iu/ml). a total of 502 (87.5 per cent) and 437 (76.2 per cent) of these had protective titres against diphtheria and tetanus respectively. the vaccination status of these subjects against diphtheria and tetanus was not ascertainable. the relevance ... | 1993 | 8014436 |
| immunity to diphtheria in women of childbearing age in delhi in 1994: evidence of continued corynebacterium diphtheriae circulation. | blood samples from 171 full-term pregnant women (aged 18-38 years) of middle socioeconomic status from delhi were tested for diphtheria antitoxins by indirect hemagglutination (iha) test. history of primary immunization/clinical diphtheria during childhood was not ascertainable, but none had been revaccinated against diphtheria at any time. about 94% women had very high antitoxin titers (> or = 0.125 iu/ ml); none had antitoxin titer less than 0.015 iu/ml, the minimum protective level. the titer ... | 1996 | 9279989 |
| diphtheria is declining but continues to kill many children: analysis of data from a sentinel centre in delhi, 1997. | although diphtheria is declining in delhi, case fatality rates (cfrs) are rising. in 1997, of 143 clinically suspected cases admitted to the infectious diseases hospital 45 (32%) died. we examined their records to understand the epidemiology and reasons for high cfrs. about 53% of cases were from delhi; they were not limited to any particular area. all the deaths and 92% (131/143) of cases occurred in children below 10 years of age. only 12% of cases had received one or more doses of dpt. muslim ... | 1999 | 10579439 |
| bacteriological & epidemiological characteristics of diphtheria cases in & around delhi -a retrospective study. | diphtheria infections caused by the different toxigenic biotypes of corynebacterium diphtheriae are endemic in delhi. information on biochemical identification, toxigenicity and antimicrobial susceptibility to this bacterium is scanty. this retrospective study was carried out to identify isolated corynebacteria biochemically, determine their toxigenicity, drug sensitivity and some epidemiological characteristics of diphtheria cases from delhi and adjoining states for the period 1998-2004. | 2007 | 18219082 |
