“…They recommended using molecular typing to study the epidemiology of V. vulnificus infections (Sanjuán & Amaro 2007, Sanjuán et al 2009). Although biotype 1 was considered to be primarily pathogenic to humans and mainly foodborne (Tison et al 1982, Hsueh et al 2004, based on our results of hiMLST, we found no identical published human strains in the database (http://pubmlst.org/ vvulnificus). However, the isolated zoonotic biotype 2 strain ST 112 correlated perfectly to the ST 112 of the database.…”

Biotype 1 has been isolated from seawater (Veenstra et al 1993a,b, Hor et al 1995, Hsueh et al 2004), eels and oysters (Coleman et al 1996) but has thus far been considered non-pathogenic for eels , Coleman et al 1996, although it can cause disease in tilapia and carp (Sakata & Hattori 1988). Biotype 2 has mainly been found in diseased eels (Tsai et al 1990, Biosca et al 1991.…”

Vibrio vulnificus is a potentially zoonotic bacterial pathogen of fish, which can infect humans (causing necrotic fasciitis). We analysed 24 V. vulnificus isolates (from 23 severe eel disease outbreaks in 8 Dutch eel farms during 1996 to 2009, and 1 clinical strain from an eel farmer) for genetic correlation and zoonotic potential. Strains were typed using biotyping and molecular typing by high-throughput multilocus sequence typing (hiMLST) and REP-PCR (Diversilab ® ). We identified 19 strains of biotype 1 and 5 of biotype 2 (4 from eels, 1 from the eel farmer), that were subdivided into 8 MLST types (ST) according to the international standard method. This is the first report of V. vulnificus biotype 1 outbreaks in Dutch eel farms. Seven of the 8 STs, of unknown zoonotic potential, were newly identified and were deposited in the MLST database. The REP-PCR and the MLST were highly concordant, indicating that the REP-PCR is a useful alternative for MLST. The strains isolated from the farmer and his eels were ST 112, a known potential zoonotic strain. Antimicrobial resistance to cefoxitin was found in most of the V. vulnificus strains, and an increasing resistance to quinolones, trimethoprim + sulphonamide and tetracycline was found over time in strain ST 140. Virulence testing of isolates from diseased eels is recommended, and medical practitioners should be informed about the potential risk of zoonotic infections by V. vulnificus from eels for the prevention of infection especially among high-risk individuals. Additional use of molecular typing methods such as hiMLST and Diversilab ® is recommended for epidemiological purposes during V. vulnificus outbreaks.

“…Among healthy persons, V. vulnificus infection is most likely associated with a history of cutaneous injury caused by handling seafood, which can allow the bacteria to enter the body through an open wound. The risk of exposure is more important in this locality than in other areas where swimming or eating raw oysters and undercooked seafood are the major risk factors (4,(6)(7)(8), possibly because fresh seafood is widely consumed, and seafood is easily accessible in wet markets in Hong Kong. Our study shows that the risk is higher during the summer, which is consistent with the fact that V. vulnificus is more active in warmer temperatures (9).…”

“…For example, aggregation and particle settling presents an efficient mode of bacterial removal from surface waters (e.g., Characklis et al 2005), potentially altering the exposure of local populations using the affected water body (e.g., Maugeri et al 2004). In addition, attachment to phytoplankton cells may affect the concentrations accumulated in shellfish, which is a major route of exposure to Vibrio (Murphree and Tamplin 1995, Linkous and Oliver 1999, Hsueh et al 2004, Marino et al 2005.…”

Abstract. Bacterioplankton response to eutrophication is a critical part of the transition from phytoplankton blooms to bottom-water hypoxia in estuaries. This topic is of particular concern when endemic bacterial populations, such as Vibrio sp., may pose a health risk to local human populations using estuaries for recreation and food. The purpose of this study was to observe the dynamics of both Vibrio and phytoplankton in the Neuse River Estuary (NRE) in North Carolina, USA, during the summer of 2004. Vibrio concentrations, particle suspension characteristics, and chlorophyll a were measured in surface water collected at a series of stations along the estuarine gradient. Consistent with previous studies, a strong positive relationship between Vibrio concentration and salinity was found. Both Vibrio sp. and phytoplankton concentrations increased moving downstream, but beyond the salt front, phytoplankton declined while Vibrio sp. concentrations continued to increase. In surface waters, a large portion of suspensions was comprised of phytoplankton cells. The fraction of Vibrio cells attached to phytoplankton increased with phytoplankton concentration and decreased with increasing salinity. These observations of Vibrio dynamics in the NRE provide evidence that populations interact with phytoplankton populations in surface waters. This information may prove critical for models of estuarine bacterial dynamics in response to eutrophication.
