This literature review presents major environmental indicators and their optimum variation ranges for the prevalence of Vibrio parahaemolyticus in the marine environment by critically reviewing and statistically analyzing more than one hundred studies from countries around the world. Results of this review indicated that the prevalence of Vibrio parahaemolyticus in the marine environment is primarily responsive to favorable environmental conditions that are described with environmental indicators. The importance of environmental indicators to the prevalence of Vibrio parahaemolyticus can be ranked from the highest to lowest as Sea Surface Temperature (SST), salinity, pH, chlorophyll a, and turbidity, respectively. It was also found in this study that each environmental indicator has an optimum variation range favoring the prevalence of Vibrio parahaemolyticus. Specifically, the SST range of 25.67 ± 2 °C, salinity range of 27.87 ± 3 ppt, and pH range of 7.96 ± 0.1 were found to be the optimum conditions for the prevalence of Vibrio parahaemolyticus. High vibrio concentrations were also observed in water samples with the chlorophyll a range of 16-25 μg/L. The findings provide new insights into the importance of environmental indicators and their optimum ranges, explaining not only the existence of both positive and negative associations reported in the literature but also the dynamic associations between the Vibrio presence and its environmental drivers.

N-methyladenosine (m6A) modification is a prevalent mRNA modification that regulates diverse biological processes in eukaryotes, including immune responses. While the role of m6A in mammalian immunity has been explored, its involvement in the immune defense of invertebrates, particularly marine bivalves which face constant pathogen challenges, remains largely unknown. Here, we investigated the function of methyltransferase-like 3 (METTL3), a key m6A "writer" enzyme, in the immune response of the marine bivalve Mytilus coruscus against Vibrio alginolyticus infection.

The gene , encoding the mannitol transporter subunit IICBA of the phosphotransferase system, was the core gene with the greatest variability in and could be used as a new typing marker in . To expand its application, we performed an evolutionary analysis and found that the gene was present in nine phyla, 371 genera, and 1,662 species of bacteria. It is commonly found in pathogenic species of , followed by , , etc.

Crustaceans are housed in zoos and aquariums and have also gained importance in the private sector and food industry. Shell lesions are common and often attributed to bacterial infections. However, few controlled studies have been performed evaluating antibiotics in crustaceans.

Ecytonucleospora hepatopenaei (EHP), a microsporidian parasite first named and characterized from the Penaeus monodon (black or giant tiger shrimp), causes growth retardation and poses a significant threat to shrimp farming. We observed shrimp farms associated with disease conditions during our fish disease surveillance and health management program in West Bengal, India. Shrimp exhibited growth retardation and increased size variability, particularly in advanced stages, exhibiting soft shells, lethargy, reduced feeding and empty midguts.
