Journal of Applied Microbiology, Volume 133, Issue 3, Page 1146-1155, September 2022. Aims Despite the recent prosperity of shrimp cultivation in China, very little is known about how different shrimp farming models influence the dynamics of Vibrio parahaemolyticus populations and the antibiotic resistance of this bacterium. Methods and Results To this end, we conducted continuous surveillance of V. parahaemolyticus on fo

Journal of Applied Microbiology, Accepted Article. Vibrio spp. are associated with water and seafood-related outbreaks worldwide. They are naturally present in aquatic environments such as seawater, brackish water and freshwater environments.

Journal of Applied Microbiology, Volume 132, Issue 2, Page 760-771, February 2022. Aims To investigate the relationships between individual health status of oysters, particularly with regard to parasitic infection, and variability in abundance of human-pathogenic Vibrio species. Methods and Results Aquacultured eastern oysters, Crassostrea virginica, were analysed individually for infection by the protozoan parasite Perkinsus marin

Journal of Applied Microbiology, Accepted Article. Aims
Vibrio (V.) parahaemolyticus is one of the most frequently occurred pathogens in mariculture. This study aimed to explore the mechanism of the impact of Ulva fasciata (U. fasciata) on the motility and biofilm formation of V. parahaemolyticus.

Journal of Applied Microbiology, Accepted Article. Aims
To determine the occurrence, diversity, antibiotic resistance and biofilm formation of V. parahaemolyticus isolated from marine fishes in Bangladesh.

In the age where bacterial resistance to conventional antibiotics is increasing at an alarming rate, the use of the traditional plant, herb extracts, or other bioactive constituents is gradually becoming popular as an anti‐virulence agent to treat pathogenic diseases. Carvacrol, a major essential oil fraction of Oregano possesses a wide range of bioactivities. Therefore, we aimed to study the effect of sub‐inhibitory concentrations of carvacrol on major virulence traits of V. cholerae.

Aims Infection of seafood with pathogenic species of the genus Vibrio causes human food‐borne illnesses. This study was executed to examine the antimicrobial‐resistance phenotypes, biofilm‐forming capability, and virulence‐associated genes of Vibrio from fish and shellfishes. Methods and results Three hundred fresh water and marine fish and shellfish samples were collected from wet markets and supermarkets in Mansoura, Egypt.

Aims Acute hepatopancreatic necrosis disease (AHPND) caused by Vibrio parahaemolyticus has emerged as a severe bacterial disease of cultured shrimp. To identify the key virulence factors, two AHPND‐causing V. parahaemolyticus (VpAHPND) strains (123 and 137) and two non‐VpAHPND strains (HZ56 and ATCC17082) were selected.

Aim To test whether engineered nanopores on the outer membrane (OM) of Escherichia coli can increase expression of heterologous proteins by making additional nutrients available to the host. Methods and Results Outer membrane nanopores were generated by expressing recombinant Vibrio parahaemolyticus CsgG (rVpCsgG), which spontaneously assembles into a pore forming channel on the OM, allowing spontaneous diffusion of small chemical entities from the exterior.

Aims This experimental study focuses on survival and consistence of Vibrio parahaemolyticus in cold water sediments and how increasing temperature and nutritional availability can affect growth. Methods and Results A pathogenic strain of V. parahaemolyticus was inoculated in seawater microcosms containing bottom sediment. Gradually, during 14 days, the temperature was upregulated from 8 to 21°C. Culturable V.

Aim The current study was conducted to determine the incidence, antibiotic resistance and virulence genes of Vibrio strains isolated from ready‐to‐eat shrimps in Edo and Delta States, Nigeria. Methods and Results A total of 1440 ready‐to‐eat shrimp's samples were obtained from open markets from November 2016 to October 2017 and analysed using standard culture‐based procedures.

Aims:  To develop simple and rapid PCR‐fingerprinting methods for Vibrio cholerae O1 (El Tor and classical biotypes) and O139 serogroup strains which cause major cholera epidemics, on the basis of the diversity of superintegron (SI) carried by these strains. Methods and Results:  PCR‐restriction fragment length polymorphism (PCR‐RFLP) assay was developed targeting region between integrase gene in the SI and its nearby ORF, followed by BglI digestion. Besides, a V.

Abstract

Aims

This study conducted bacterial community, virulence and antibiogram profiling inside the hindgut and skin of freshly caught hilsa fish and those sold at markets.

Abstract

Aims

Microbiological, biotechnological and chemical characterization of a previously undescribed aryl-crowned polyketide from Bacillus subtilis MTCC 10403 isolated from brown seaweed Anthophycus longifolius with activity against opportunistic Gram-negative food-borne pathogenic bacterial strains.

Abstract

Aims

To investigate the virulence of the Vp_PirAB-like genes in Vibrio parahaemolyticus-AHPND causing strain and factors that associate with the virulence level.
