“…From copepods to mollusks, and from marine aggregates to fish, Vibrio bacteria have been at the heart of many marine symbiotic and ecological studies. With over 110 species described, the genus Vibrio represents one of the largest fractions of culturable marine bacteria (Farmer and Janda, 2015;Logue and Nde, 2017), many of which are pathogenic to animals or humans. These pathogenic Vibrio species are of particular interest to the aquaculture industry and to human health in coastal areas.…”

The potential spread of infectious diseases in response to climate change and rising sea surface temperatures in temperate regions has been a growing concern for the past several decades. Extreme heat waves in the North Atlantic and North Sea regions have been correlated with an increase in human Vibrio infections; of particular concern to human health are Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus. While these species are well-known to cause disease in humans, most environmental strains are not pathogenic. Studying not only the behavior of the pathogenic strains, but that of non-pathogenic environmental isolates, may better elucidate their ecological relationship in their native microbiome and the dispersal of these species in coastal regions. Using red fluorescent protein-tagged and gentamycin-resistant V. cholerae, V. parahaemolyticus, and V. vulnificus strains, we investigated whether increasing temperatures confer greater competitive fitness to these species when incubated within a natural North Sea water sample still containing its microbiome in a small-scale niche investigation. Increased incubation temperatures alone did not confer a competitive advantage to V. cholerae, V. parahaemolyticus, and V. vulnificus. The microbial community could limit Vibrio growth at all temperatures. To the best of our knowledge, we also demonstrate the first (albeit unintentional) genetic modification of multiple species of marine bacteria through the introduction of a genetically modified V. vulnificus strain into a natural water sample in a contained system.

Vibriosis in shrimp farms poses potential risks to the industry’s sustainability and the consumers’ health. Little is known about the dynamics and variation of Vibrio spp—population in shrimp production in Sarawak, Malaysia. The apparent prevalence of three Vibrio species, V. parahaemolyticus, V. cholerae, and V. alginolyticus, were investigated in water (n=12), sediment (n=12), shrimp (n=12), and effluent (n=12) samples collected from two ponds in a coastal shrimp farm during one production cycle. Multiplex-PCR using specific primer sets showed the presence of the three Vibrio species. Based on the results, V. parahaemolyticus was the most prevalent in all four samples, with a contamination rate of 97.92% (95% CI: 89. 10 to 99.89%), while V. cholerae and V. alginolyticus had a contamination rate of 47.92% (95% CI: 34.37 to 61.67%) and 25.0% (95% CI: 14.92 to 38.78%), respectively. High Vibrio load in the shrimp farm is due to favourable environmental factors, such as optimal temperatures, salinity, and pH ranges for the growth of these species. The study’s findings offer important preliminary insights into the prevalence and distribution of these pathogenic Vibrio spp., within a shrimp farm in Kuching, Sarawak. This study serves as a potential model for monitoring Vibrio spp. prevalence in other shrimp farms across Sarawak, thereby addressing the scarcity of data on prevalence in the region.
