| [application of pulsed-field gel electrophoresis typing in tracing and carrying out surveillance programs on o139 cholera outbreaks]. | to study the characteristics of molecular typing and phylogenic relationship among the vibrio cholerae serogroup o139 strains isolated from environment and sea food samples during cholera outbreaks, in sichuan province in 2004 and to trace the source of infections so as to support the ascertainment of epidemic control strategy. | 2006 | 16749988 |
| [outbreak of cholera associated with consumption of soft-shelled turtles, sichuan province, china, 2009.] | objective: vibrio cholera was extremely rare in sichuan province(no cases in 2008). any outbreak could indicate contamination through the food supply system. in july 2009, a hospital reported a cluster of 7 diarrhea patients;all attended the same banquet. one patient was confirmed to have vibrio cholera (o139). we conducted this investigation to identify the source of this possible cholera outbreak. methods: we defined a suspect case as any banquet attendee with diarrhea (≥ 3 times/day). a confi ... | 2010 | 21162875 |
