Galicia in northwestern Spain has been considered a hotspot for Vibrio parahaemolyticus infections. Infections abruptly emerged in 1998 and, over the next 15 years, were associated with large outbreaks caused by strains belonging to a single clone. We report a recent transition in the epidemiologic pattern in which cases throughout the region have been linked to different and unrelated strains. Global genome-wide phylogenetic analysis revealed that most of the pathogenic strains isolated from…

Large-scale genomic epidemiology reveals the cryptic outbreaks, hidden persistent reservoirs, and spatiotemporal dynamics of Vibrio parahaemolyticus
Large-scale phylogenomic analysis of 3,642 isolates and epidemiological data performed “ data-driven” outbreak detection and described the long-term outbreak dynamics of the leading seafood-associated bacterial pathogen, Vibrio parahaemolyticus, in a high-prevalence city, Shenzhen, China, over a 17-year period.
Uneven morbidity levels were established for years of observation with increase in the summer-autumn period, the food-borne transmission was dominant for the acute enteric infection; and mainly people in the 20-30 age group were involved in the epidemic process.
Characterization of a novel Vibrio parahaemolyticus host-phage pair and antibacterial effect against the host.
Investigation of a novel V. parahaemolyticus host-phage pair and the antibacterial effect of the phage on the strain BTXS2 provides insights into marine microbial ecology and risks.

  • 2021
The clinical course and microbiological characteristics of Vibrio infections in Germany in 2018 and 2019 are described, and clusters of three identical strains of V. vulnificus, which caused wound infections, suggest that some clonal lines can spread across the Baltic Sea.
Molecular identification of pathogenic bacteria causing foodborne disease in Caulerpa racemosa
The sequencing analysis showed that the three bacterial colonies of C. racemosa isolate had high similarity with V. parahemolyticus, Caldalkalibacillus mannanilyticus and Exiguobacterium profundum, which is a green algae consumed by people in northern coastal areas.


Emergence of Asiatic Vibrio Diseases in South America in Phase With El Niño
These findings identify the El Niño episodes as a reliable vehicle for the introduction and propagation of Vibrio pathogens in South America.
Genomic Variation and Evolution of Vibrio parahaemolyticus ST36 over the Course of a Transcontinental Epidemic Expansion
Genetic analysis was used to examine the evolutionary divergence that has occurred over the course of the most recent transcontinental expansion of a pathogenic Vibrio, the spreading of the V. parahaemolyticus sequence type 36 clone from the region where it is endemic on the Pacific coast of North America to the east coast of the United States and finally to the west coast of Europe.
Characterization of Pathogenic Vibrio parahaemolyticus Isolates from Clinical Sources in Spain and Comparison with Asian and North American Pandemic Isolates
The results of this study suggest that a unique and specific clone could be related to the V. parahaemolyticus infections in Europe.
Population Structure of Clinical and Environmental Vibrio parahaemolyticus from the Pacific Northwest Coast of the United States
The Pacific Northwest population exhibited a semi-clonal structure attributed to an environmental clade clonally related to the pandemic O3:K6 complex and a clinical clade genetically related to a regionally endemic O4:K12 complex.
Environmental Determinants of the Occurrence and Distribution of Vibrio parahaemolyticus in the Rias of Galicia, Spain
Characterization of the isolates obtained from the study resulted in the first identification of two pathogenic tdh-positive strains of V. parahaemolyticus dominant in infections in Spain in the last 10 years.
Epidemiological investigation of a foodborne outbreak in Spain associated with U.S. West Coast genotypes of Vibrio parahaemolyticus
We describe an outbreak of seafood-associated Vibrio parahaemolyticus in Galicia, Spain in on 18th of August 2012 affecting 100 of the 114 passengers travelling on a food banquet cruise boat.
Genetic Diversity of Clinical and Environmental Vibrio parahaemolyticus Strains from the Pacific Northwest
The presence of significant concentrations of tdh +, trh-negative environmental strains in the PNW that have not been responsible for illness and T3SS2β in tdh- and trh -negative strains emphasizes the diversity in this species and the need to identify additional virulence markers for this bacterium to improve risk assessment tools for the detection of this pathogen.
Increase in Vibrio parahaemolyticus Infections Associated with Consumption of Atlantic Coast Shellfish — 2013
Vibrio parahaemolyticus (Vp) is found naturally in coastal saltwater and causes foodborne infections annually, of which most are attributable to consumption of raw or undercooked shellfish.
Pandemic Vibrio parahaemolyticus O 3 : K 6 , Europe
The results presented did represent a sequence associated with the Orientalis biovar and, therefore, authentic and may end the controversy.
