Abstract

Abstract Background Human infections with non-O1, non-O139 V. cholerae have been described from Laos. Elsewhere, non cholera-toxin producing, non-O1, non-O139 V. cholerae have been described from blood cultures and ascitic fluid, although they are exceedingly rare isolates. Case presentation We describe a farmer who died with Vibrio cholerae O21 bacteremia and peritonitis in Vientiane, Laos, after eating partially cooked apple snails (Pomacea canaliculata) and mussels (Ligumia species). The cultured V. cholerae were non-motile. PCR detected ompW and toxR gene regions but not the ctxA, ompU, omp K and TCP gene regions. Although the organisms lacked flagellae on scanning electron microscopy, they possessed the Vibrio flagellin flaA gene. Conclusion Severe bacteremic non-O1, non-O139 V. cholerae is reported from Laos. The organisms were unusual in being non-motile. They possessed the Vibrio flagellin flaA gene. Further research to determine the reasons for the non-motility and virulence is required.

Abstract

This paper presents the results of an investigation on water-borne infectious diseaseconducted among the people of Attapeu province from 2003 to 2008. Regardless of the lastcholera epidemic in Attapeu province, Lao PDR in the year 1999, the local peoples'awareness of cholera was remarkably low, as demonstrated by the knowledge survey ondiarrheal diseases performed in the province in 2006. In the case study material, derivedfrom continuous field observations on malaria among permanent residents in relocatedvillages in Sanxay district from 2004 to 2008, the infection rate among febrile cases was ashigh as 45% in the early resettlement period, while it was proved that the rate fell later to1.9-14%. Judging from the environmental condition of this settlement area, this papermakes clear the persistent threat of malaria. Furthermore, among the villagers, hookworminfection was highly prevalent. However, liver fluke infections were scarce and noascariasis was found from parasitic stool examination in 2007. Water quality analysis ofthe water sources resulted in remarkably safe water from tube wells from 2003 to 2008.
