Vibrio parahaemolyticus, Southern Coastal Region of China, 2007–2012

Abstract

We analyzed the prevalence and characteristics of Vibrio parahaemolyticus among patients with acute infectious diarrhea in the southern coastal region of China. V. parahaemolyticus was the leading cause of bacterial infectious diarrhea in this region during 2007–2012. Serotype O3:K6 strains were most common, followed by serotypes O4:K8 and O3:K29.

The 12 Gastrointestinal Pathogens Spectrum of Acute Infectious Diarrhea in a Sentinel Hospital, Shenzhen, China

“…Only four cases of V. parahaemolyticus were detected, which differed from previous survey that V. parahaemolyticus has been the leading cause of bacterial infectious diarrhea in coastal regions of China (Li et al, 2014). The low frequency of isolation of V. parahaemolyticus may due to the improvement in hygiene and thus the consumption of undercooked or cross-contaminated shellfish decreased, which was commonly associated with V. parahaemolyticus infection.…”

“…The low frequency of isolation of V. parahaemolyticus may due to the improvement in hygiene and thus the consumption of undercooked or cross-contaminated shellfish decreased, which was commonly associated with V. parahaemolyticus infection. All the three isolates serotyped as O3:K6 were tdh + trh -, which was consistent with the surveillance data collected in Shenzhen that O3:K6 serotype was dominant in this region (Li et al, 2014). …”

“…Although these common enteropathogens have been extensively studied in China (Bai et al, 2004; Qu et al, 2012; Li et al, 2014), and the laboratory-based surveillance for acute infectious diarrhea has been established in Shenzhen City since 2007, few comprehensive studies covering a broad range of diarrheal agents have been undertaken. Furthermore, the long-term fluctuation in the frequency of infections with the common gastrointestinal pathogens captured by this surveillance system suggested the etiology of acute infectious diarrhea in this region has changed obviously during the past few years.…”

Risk Factors for Vibrio parahaemolyticus Infection in a Southern Coastal Region of China

“…Serotype O3:K6 ( tdh + trh −) was the most common serotype among VP patients identified in this study, consistent with other studies (Chao et al ., 2009; Ma et al ., 2013; Li et al ., 2014). Risk factors associated with infection with serotype O3:K6 were the following: having pre-existing chronic disease, eating raw (undercooked) seafood and meat, eating food from a street food vendor, and eating vegetable salad.…”

“…In 2007, Shenzhen began conducting enhanced surveillance for acute infectious diarrhea at selected hospitals. VP has been found to be the most frequently isolated pathogen; more than 80% of cases occur from April to October (Li et al ., 2014). To identify possible dietary and medical risk factors for VP infections, and to determine whether there are unique risk factors in China compared with other countries, we conducted a case–control study in Shenzhen.…”
