| a large cholera outbreak due to a new cholera toxin variant of the vibrio cholerae o1 el tor biotype in orissa, eastern india. | a total of 32 vibrio cholerae isolates were collected during a recent large cholera outbreak in eastern india. biochemical and serological studies revealed that all of the isolates belonged to serogroup o1, biotype el tor, serotype ogawa. two multiplex pcr assays confirmed the presence of various toxigenic and pathogenic genes - ace, ctxab, hlya, ompu, ompw, rfbo1, rtx, tcp, toxr and zot - in all of the isolates. sequencing of the ctxb gene from the isolates revealed a novel mutation in the gene ... | 2009 | 19141742 |
| two sequential outbreaks in two villages illustrate the various modes of transmission of cholera. | we investigated two sequential outbreaks of severe diarrhoea in two neighbouring villages of orissa, in 2005. we conducted descriptive and matched case-control studies. the attack rates were 5.6% (n=62) and 5.2% (n=51), respectively, in the first and second villages. one death was reported in the second village (case fatality 2%). we identified that consumption of milk products prepared in the household of the index case [matched odds ratio (mor) 5.7, 95% confidence interval (ci) 1.7-30] in the ... | 2009 | 19171080 |
