Vibrio cholerae O1 bacteremia in Pakistan: analysis of eight cases.

Bacteremia caused by Vibrio cholerae O1 has been a rare phenomenon. We report on eight cases of V. cholerae O1 bacteremia from Pakistan which occurred during 1992-2008. Six of the cases were seen in children (two neonates and four infants) and seven of the eight patients were female. Urogenital malignancy, hepatitis B virus-associated end-stage liver disease, concurrent Campylobacter enteritis and prematurity were the underlying conditions in four patients. Two of the eight patients died and one was lost to follow up and this outcome may be due to prior immunity leading to less severe illness.
