As the fastest growing food production industry in the world, aquaculture contributes nearly half of the global fish consumption. Over the past three decades, aquaculture has grown at an average annual rate of about 6%. In animal production systems for human food, the feed conversion rate of cultured fish is higher than that of terrestrial animals. It is predicted that in the next few decades, the total production of fish from fishing and aquaculture will exceed that of beef, pork and poultry combined. However, various fish diseases are emerging in the aquaculture industry along with the expansion of breeding scale, in particular the bacterial diseases. Although it may be efficient to administer low levels of drugs, it is worth noting that this practice must be conducted to avoid toxicity to fish, as well as alertness to the possible appearance of drug-resistant strains. Thus, it is crucial to seek novel and effective solutions for healthy aquaculture, which requires us to have a more clear and systematic understanding of the molecular mechanism of bacterial diseases.
This Research Topic aims to present the current state of knowledge regarding molecular mechanisms of bacterial diseases in cultured fishes, especially mechanisms related to the cellular and molecular biological events that occur in cells of hosts and pathogens during their interaction within the harsh environment of the infected hosts.
This Research Topic on “Molecular mechanisms of bacterial disease in cultured fishes” had the bullet points as below:
• Emerging bacterial disease in cultured fishes with a wide impact and its progresses.
• Mechanisms for bacterial pathogens to modulate the expression of virulence factors.
• Mechanisms of immune escape and histopathology.
• Interactions in complex infection settings comprising of bacterial pathogens, their hosts and the resident gut microbiota.
