“…Vezzulli et al (2010) and Schets et al (2010) identified seawater temperature as a key factor influencing the presence of Vibrio spp., for instance it is well documented that V. parahaemolyticus favours warmer water temperatures (Sobrinho et al, 2010). Recently, pathogenic V. parahaemolyticus was detected even in temperate European waters (Baker-Austin et al, 2010;Martinez-Urtaza et al, 2005). Martinez-Urtaza et al (2008) observed higher occurrence of this taxon during periods of lower salinity and in general this taxon was primarily detected in areas of reduced salinity close to freshwater discharge runoff, which is also in agreement with our findings.…”

“…Although Vibrio infections are common in tropical areas, the last decade showed a significant increase in documented cases also in European regions, such as in the Mediterranean Sea (Gras-Rouzet et al, 1996;Martinez-Urtaza et al, 2005) or in the more temperate Northern waters (Eiler et al, 2006). Prior studies reported that the number of Vibrio infections correspond closely with the sea surface temperature pointing to a possible link to climate change related phenomena (e.g.…”

The taxonomic composition of biofilms on marine microplastics is widely unknown. Recent sequencing results indicate that potentially pathogenic Vibrio spp. might be present on floating microplastics. Hence, these particles might function as vectors for the dispersal of pathogens. Microplastics and water samples collected in the North and Baltic Sea were subjected to selective enrichment for pathogenic Vibrio species. Bacterial colonies were isolated from CHROMagar™Vibrio and assigned to Vibrio spp. on the species level by MALDI-TOF MS (Matrix Assisted Laser Desorption/IonisationTime of Flight Mass Spectrometry). Respective polymers were identified by ATR FT-IR (Attenuated Total Reflectance Fourier Transform -Infrared Spectroscopy). We discovered potentially pathogenic Vibrio parahaemolyticus on a number of microplastic particles, e.g. polyethylene, polypropylene and polystyrene from North/Baltic Sea. This study confirms the indicated occurrence of potentially pathogenic bacteria on marine microplastics and highlights the urgent need for detailed biogeographical analyses of marine microplastics.

“…Currently, there is no unanimity in the scientific community with regard to identifying a single marker for pandemic strains and suspected V. parahaemolyticus pandemic isolates have been identified by positive group-specific PCR, based on a sequence variation in the toxRS gene (Okura et al, 2003;Han et al, 2008) and the presence of the tdh gene. Quilici et al (2005) and Martinez-Urtaza et al (2005) reported evidence that pandemic V. parahaemolyticus had migrated into Europe and has been isolated from clinical cases in France (Quilici et al, 2005), in Spain (Martinez-Urtaza et al, 2005) and in Russia during gastroenteritis outbreaks (Smolikova et al, 2001).…”

In 2005, pandemic Vibrio parahaemolyticus was reported to have been introduced in Europe: O3:K6 strains were isolated from clinical cases in France and Spain, and were found to be associated with consumption of contaminated seafood. On the contrary, pandemic strains were not isolated from seafood or from the environment itself. Analysis of two V. parahaemolyticus strains isolated in May 2007 from Northern Italy seawater and plankton samples revealed the presence of the virulence gene tdh and the pandemic-specific markers orf8 and toxRS/new sequence (group-specific PCR). The two strains showed serotypes not included in the 'pandemic group', but their molecular typing proved that they represent a single clone showing a genetic profile very similar to that of pandemic O3:K6 reference isolates. Moreover, the two marine strains carried three virulence-related genes associated with clinical strains and, to date, hardly ever or never detected in environmental strains. The presence, in strains isolated from the marine environment, of genetic pandemic markers and virulence genes normally associated with clinical isolates proves that marine strains might constitute a public health concern.

“…During the next year the new clone was isolated from V. parahaemoìyticus infections throughout Asia. In June of 1997 the 03:K6 strain spread to Peru, for the first time beyond Asia and later that year it was implicated in an outbreak in Chile (Martinez -Urtaza et al 2005). In 1998, a large outbreak was reported in the USA, which was associated with consumption of raw contaminated oysters (Daniels et al 2000).…”

“…This was the first definitive evidence of the Κ parahaemoìyticus pandemic and the term "pandemic clone" was designated (Gonzalez -Escalona et al 2008, Chowdhury et al 2000. Since then, a spread of this pandemic strain to Europe has been reported and it was isolated from outbreaks in France (Quiiici et al 2005), Spain (Martinez -Urtaza et al 2005), Italy (Ottaviani et al 2008), as well as from other countries like Russia (Nail et al 2007) or Mozambique ( Ansaruzzaman et al 2005). In 2005, the largest F. parahaemoìyticus outbreak caused by the pandemic 03;K6 strains (11000 human cases) was reported in Chile and it was associated with shellfish consumption (Fucnzalida et al 2006).…”

Among the 30 species of the genus Vibrio, only 13 of them are pathogenic to humans. All pathogenic vibrios have been reported to cause foodborne diseases, although Κ parahaemolyticus is considered the most important pathogenic Vibrio. V parahaemolyticus is a halophilic bacterium that occurs naturally in aquatic environments worldwide. The pathogen caused sporadic diarrhoea mainly associated with the consumption of raw or undercooked seafood up to recent years. Since 1996, the incidence of V. parahaemolyticus infections has increased dramatically. V. parahaemolyticus is the leading cause of seafood associated bacterial gastroenteritis in the United States and of the half foodborne outbreaks in some Asian countries. This increase in incidence has been related to the emergence of the 03:K6 serovar. The pathogenic V. parahaemolyticus strains can produce a thermostable direct hemolysin or a thermostable direct hemolysin-related hemolysin, which arc encoded by the tdh and trh genes, respectively. Vibrio parahaemolyticus has not been included in the microbiological criteria of E.U. Food legislation, probably because the risk by this pathogen was considered rather low in liurope. However, climate changes favour the growth of the pathogen in seawater. Recent studies in Spain and France have shown that V. parahaemolyticus infections from seafood consumption have been increased. The emergence of the pathogen in liurope is of public health concern and emphasizes the importance of microbiological surveillance and control programs for V, parahaemolyticus.
