The Hippo-Yki signaling pathway plays a crucial role in numerous biological processes.

The main goal of the present study was to evaluate the influence of thermal exposure on Vibrio population and HSP genes expression (HSP 90, HSP70, and HSP20) in rayed pearl oyster (P. radiata). To this end, the oysters were reared for 30 days at temperatures of 22 °C (control), 25 °C, 27 °C, and 29 °C. The results showed that five dominate Vibrio strains including Vibrio hepatarius, V. harveyi, V.

Organic fertilizers can partially replace chemical fertilizers to improve agricultural production and reduce negative environmental impacts.

Climate change is one of the most important threats to farmed abalone worldwide. Although abalone is more susceptible to vibriosis at higher water temperatures, the molecular mode of action underlying this has not been fully elucidated. Therefore, this study aimed to address the high susceptibility of Halitotis discus hannai to V.

Clarifying mechanisms underlying the selective adhesion of probiotics and competitive exclusion of pathogens in the intestine is a central theme for shrimp health.

Variation exists in milk protein concentration of dairy cows of the same breed that are fed and managed in the same environment, and little information was available on this variation which might be attributed to differences in rumen microbial composition as well as their fermentation metabolites.

Shrimp immunology is vital in establishing prophylactic and therapeutic strategies for controlling pathological problems that threaten shrimp production. Apart from dietary treatments, the adenosine 5′-monophosphate-activated protein kinase (AMPK), an important regulatory enzyme that restores cellular energy balance during metabolic and physiological stress, is known to have therapeutic potential to improve shrimp's defense mechanism.

Vibrio spp. cause vibriosis in many saltwater and freshwater aquatic species, such as fish, crustaceans, and mollusks. Vibrio parahaemolyticus and Vibrio alginolyticus are among the few Vibrio species commonly found in infections in fish. This study aimed at investigating the chemical composition and evaluating the antibacterial activities of Salix babylonica L.

Vibrio parahaemolyticus illnesses, often associated with the consumption of raw or undercooked oysters, are most common in summer months when higher temperatures increase V. parahaemolyticus levels in the environment. In Washington, post-harvest controls focus on the time from harvest to temperature-controlled storage to minimize V.

In recent years, trade liberalisation has led to the spread of antibiotic-resistant bacteria (ARB) in food products. Because ARB has reportedly been found in imported foods, the spread of plasmid-mediated ARB through food products is a concern. Here, we report the complete genome sequences of ESBL-producing Vibrio vulnificus and V. alginolyticus strains harbouring a plasmid isolated from imported seafood. First, V. vulnificus and V.

The reference gene expression is not always stable under different experimental conditions, and screening of suitable reference genes is a prerequisite in quantitative real-time polymerase chain reaction (qRT-PCR). In this study, we investigated gene selection, and the most stable reference gene for the Chinese mitten crab (Eriocheir sinensis) was screened under the stimulation of Vibrio anguillarum and copper ions, respectively.

Introduction Vibriosis causes enormous economic losses of marine fish. The present study investigated the intestinal microbial response to acute infection of half-smooth tongue sole with different-dose Vibrio alginolyticus within 72 h by metagenomic sequencing. Methods

Phage therapy was taken as an alternative strategy to antibiotics in shrimp farming for the control of Vibrio species of Vibrio parahaemolyticus and Vibrio alginolyticus, which cause substantial mortality and significant economic losses. In this study, a new Vibrio phage vB_ValM_PVA8 (PVA8), which could efficiently infect pathogenic isolates of V. alginolyticus and V. parahaemolyticus, was isolated from sewage water and characterized by microbiological and in silico genomic analyses.

Vibrio parahaemolyticus has become an important public threat to human health. Rapid and robust pathogen diagnostics are necessary for monitoring its outbreak and spreading. Herein, we report an assay for the detection of V. parahaemolyticus based on recombinase aided amplification (RAA) combined with lateral flow dipstick (LFD), namely RAA-LFD. The RAA-LFD took 20 min at 36~38 ℃, and showed excellent specificity. It detected as low as 6.4 fg/µL of V.

The worldwide consumption of ready-to-eat seafood products has steadily increased due to a range of health benefits. However, depending on the handling or cutting process of raw fish, ready-to-eat sashimi can be exposed to microbiological risks that can lead to foodborne infection by marine pathogens.

Induced molting enables laying hens to relax, restore energy and prolong the laying hen cycle, resolving problems such as poor egg quality and minimizing economic losses caused by rising global feeding costs. However, traditional molting methods may disrupt gut microflora and promote potential pathogens infections. This study used a customized additive with a mixture of probiotics and vitamins to induce molting and examine the cecal microbiota post molting.

Biofilms are a major concern within the food industry since they have the potential to reduce productivity in situ (within the field), impact food stability and storage, and cause downstream food poisoning. Within this review, predatory bacteria as potential biofilm control and eradication agents are discussed, with a particular emphasis on the intraperiplasmic Bdellovibrio-and-like organism (BALO) grouping.

Vibrio anguillarum is a cause of vibriosis in marine fisheries worldwide, but only one previous study reported human pathogenicity of this species. Here, we report a 70-year-old man from Dalian, a coastal city in northeast China, who experienced a severe infection with V. anguillarum due to a bite on his left hand when handling hairtail, a marine fish. This patient had low immunity because of the long-term use of glucocorticoids due to nephrotic syndrome.

Journal of Fish Diseases, EarlyView. The spotted sea bass (Lateolabrax maculatus) is an economically important aquaculture fish species in East Asia. Because of its high nutritional value and delectable flavour, spotted sea bass has a high market demand (Chen et al., 2019).

by Hao-Ching Wang, Shin-Jen Lin, Han-Ching Wang, Ramya Kumar, Phuoc Thien Le, Jiann-Horng Leu Photorhabdus insect-related toxins A and B (PirA and PirB) were first recognized as insecticidal toxins from Photorhabdus luminescens. However, subsequent studies showed that their homologs from Vibrio parahaemolyticus also play critical roles in the pathogenesis of acute hepatopancreatic necrosis disease (AHPND) in shrimps.

The objective of this study was to examine the frequency and extent of antibiotic-resistant pathogens in seafood sold in Malaysia, using a systematic review and meta-analysis approach to analyze primary research studies. Four bibliographic databases were systematically searched for primary studies on occurrence. Meta-analysis using a random-effect model was used to understand the prevalence of antibiotic-resistant bacteria in retail seafood sold in Malaysia.

Vibrio alginolyticus is the common pathogen affecting various species of marine organisms. It has been demonstrated that fliR is a necessary virulence factor to adhere and infect their hosts for pathogenic bacteria. Frequent disease outbreaks in aquaculture have highlighted the necessity of developing effective vaccines.

The effects of global warming are not limited to rising global temperatures and have set in motion a complex chain of events contributing to climate change. A consequence of global warming and the resultant climate change is the rise in cyanobacterial harmful algal blooms (cyano-HABs) across the world, which pose a threat to public health, aquatic biodiversity, and the livelihood of communities that depend on these water systems, such as farmers and fishers.

Vibrio parahaemolyticus often contributed to a serious foodborne disease outbreak when marine mussels are consumed. The number of drug-resistant isolates of bacteria has also been increased, which makes clinical treatment more challenging. In general, a single food preservative cannot inhibit drug-resistant V. parahaemolyticus in seafood effectively. Inhibition effect of shrimp shell chitooligosaccharide (COS)-catechin (CAT) conjugate toward V.
