“…Till 1995, V. parahaemolyticus has been implicated with sporadic diarrhoea. With the emergence of unique serovar (O3:K6) in 1996, this organism has gained pandemicity and caused diarrhoeal outbreaks in several countries [6, 7, 8, 9, 10, 11, 12, 13]. The O3:K6 clone (pandemic strain) and its serovariants typically possess tdh genewith a distinctive toxRS operon that encodes a transcriptional regulator.…”

The role of Vibrio parahaemolyticus in causing diarrhoeal disease is well known. However, phenotypic and genetic traits of this pathogen isolated from diverse sources have not been investigated in detail. In this study, we have screened samples from diarrhoeal cases (2603), brackish water fish (301) and aquatic environments (115) and identified V. parahaemolyticus in 29 (1.1%), 171 (56.8%) and 43 (37.4%) samples, respectively. Incidence of pathogenic V. parahaemolyticus with virulence encoding thermostable-direct haemolysin gene ( tdh ) was detected mostly in fishes (19.3%) and waters (15.6%) than clinical samples (1.04%). The pandemic strain marker genes ( toxRS and PGS-sequences) have been detected relatively more in water (6%) and fish (5%) samples than in clinical samples (0.7%). Majority of the V. parahaemolyticus isolates from clinical cases and fish samples (26.3%) belonged to classical pandemic serovars (O3:K6). In addition, several newly recognised pandemic serovars have also been identified. Pulsed field-gel electrophoresis (PFGE) analysis showed clonal relatedness (60–85%) of V. parahaemolyticus from different sources. The study observation revealed that the brackish water fishes and water bodies may act as a reservoir of pathogenic V. parahaemolyticus . Emergence of several new serovars of pandemic V. parahaemolyticus signifies the changing phenotypic characteristics of the pathogen.

“…The analysis used future downscaled climate data, bias corrected with current observational data, but future weather patterns may be different. We were unable to model changes to the V. vulnificus southern extent, but this bacterium has been isolated from oysters as far south as Tabasco (18.5°N) 31 .…”

Vibrio vulnificus is an opportunistic bacterial pathogen, occurring in warm low-salinity waters. V. vulnificus wound infections due to seawater exposure are infrequent but mortality rates are high (~ 18%). Seawater bacterial concentrations are increasing but changing disease pattern assessments or climate change projections are rare. Here, using a 30-year database of V. vulnificus cases for the Eastern USA, changing disease distribution was assessed. An ecological niche model was developed, trained and validated to identify links to oceanographic and climate data. This model was used to predict future disease distribution using data simulated by seven Global Climate Models (GCMs) which belong to the newest Coupled Model Intercomparison Project (CMIP6). Risk was estimated by calculating the total population within 200 km of the disease distribution. Predictions were generated for different “pathways” of global socioeconomic development which incorporate projections of greenhouse gas emissions and demographic change. In Eastern USA between 1988 and 2018, V. vulnificus wound infections increased eightfold (10–80 cases p.a.) and the northern case limit shifted northwards 48 km p.a. By 2041–2060, V. vulnificus infections may expand their current range to encompass major population centres around New York (40.7°N). Combined with a growing and increasingly elderly population, annual case numbers may double. By 2081–2100 V. vulnificus infections may be present in every Eastern USA State under medium-to-high future emissions and warming. The projected expansion of V. vulnificus wound infections stresses the need for increased individual and public health awareness in these areas.

“…Vibrio vulnificus and V. parahaemolyticus have been detected in clams and oysters (Hernánez-Díaz et al, 2015;Lopatek, Wieczorek, & Osek, 2015;Vu et al, 2018), which is expected since they are usually part of the microbiota of the estuaries from which they are collected (Koralage et al, 2012). In Mexico, the reported prevalence of V. parahaemolyticus in oysters ranges from 30 to 50% ( Barrera-Escorcia et al, 2016;Fernández-Rendon et al, 2018;Hernánez-Díaz et al, 2015;León-Robles et al, 2013;Lizárraga-Partida & Quilici, 2009;Quiñones-Ramírez et al, 2010), which is considered the most commonly isolated species in the Mexican coast regions, followed by V. cholerae and V. vulnificus.…”

“…Vibrio cholerae, V. parahaemolyticus, and V. vulnificus are the etiological agents commonly involved in many outbreaks or infections associated with seafood consumption (Bonnin-Jusserand et al, 2017; CDC, 2016). Due to this fact, the majority of the prevalence studies are focused on the identification of these three species (Barrera-Escorcia et al, 2016;Fernández-Rendon et al, 2018;Robert-Pillot, Copin, Homber, Gay, & Quilici, 2014). However, the number of illnesses caused by V. alginolyticus, V. mimicus, and V. fluvialis has increased in the United States (CDC, 2016).…”

The bacterial biofilm formation index (BFI) is measured by a microtiter plate assay, and it is typically performed at 72 hr. However, the dynamics of biopolymer formation change during this incubation period. The aims of this study were to follow the biofilm formation dynamics of Vibrio strains isolated from samples of seafood and food contact surfaces (FCS) and to propose a new BFI classification criterion. Samples from seafood (136) and FCS (14) were collected from retail markets in Queretaro, Mexico. The presence of Vibrio spp. was determined, the strains were isolated, and the six major pathogenic species (V. cholerae, V. alginolyticus, V. fluvialis, V. parahaemolyticus, V. vulnificus, V. mimicus) were identified by PCR. The BFI of the isolates was determined by the microtiter plate method. Fifty‐one strains were isolated and identified as V. alginolytivcus (25), V. vulnificus (12), V. cholerae (7), V. parahaemolyticus (6), and V. mimicus (1). A quantitative classification criterion of biofilm formation was proposed based on the following factors: BFI dynamics (no formation, continuous increase, and increase followed by decrease), time of maximum BFI (early: 24 hr; late: 48 to 72 hr), and degree of BFI (none, weak, moderate, and strong). A numerical value was assigned to each factor to correlate the resulting BFI profile with a risk level. Thirteen BFI profiles were observed, having risk level values from 0 to 10. Vibrio alginolyticus, V. cholerae, and V. vulnificus showed the highest BFI profile diversities, which included the riskiest profiles. The proposed BFI criterion describes the dynamics of bacterial biopolymer formation and associates them with the possible risk implications. Practical Application In food processing environments, the presence of bacterial biofilms that could include foodborne pathogens might favor cross‐contamination due to direct contact or biofilm dispersal into food products. The new quantitative classification criterion for biofilm formation considers their production dynamics over time, the biofilm quantity, and the level of biofilm dispersal. These characteristics are represented by a numerical value that reflects the level of risk associated with the presence of a biofilm‐producing strain on a food contact surface.
