In October 2020, some Pelodiscus sinensis died in a farm in Hubei Province, China. To determine the pathogen and pathogenic characteristics of the disease, a dominant strain A3 was isolated from the liver of the diseased P. sinensis. Based on physiological and biochemical characteristics and 16S r...

Introduction: Today, livestock and poultry health in an advanced production system is a major challenge affecting human health and the global economy. Antibiotics have been used in poultry nutrition for many years. Chickens are raised with the assistance of the regular use of antibiotics, not only...

Antibiotics used in animal feeds have recently been strictly regulated to avoid antibiotic resistance in humans. Thus, scientists are compelled to find new feed additives to replace antibiotics in feed. Apart from having a zero effect on human health, new alternatives may even be able to further...

In recent years, the bla_NDM gene, which mediate resistance to carbapenems, has disseminated all over the world, and has also been detected in animals. Understanding the dissemination and accumulation of antibiotic resistance genes (ARGs) in a human-impacted environment is essential to solve the...

The special issue contains 8 articles that discuss various aspects of tilapia production and health in aquaculture. These include the journey of Nile tilapia from Africa to the world, the future of intensive tilapia production and the circular bioeconomy without effluents, strategies to enhance...

Tilapia culture is an important source of income and nutrition to many rural families. Since 2000, the production of tilapia increased and reached domestic and global markets. Major farmed species is Nile tilapia (Oreochromis niloticus), in earthen ponds and cage cultures. Intensification...

The emergence of antibiotic-resistant pathogenic strains of Lactococcus garvieae serotype II isolated from fish in Japan has become a growing concern in recent years. The data on drug susceptibility and its associated resistance mechanism are limited. Therefore, the present study was conducted to...

Lactococcosis, caused by members of the genus Lactococcus, represents a devastating disease inducing mass mortalities and economic losses in many fish species worldwide. The present work aimed to compare the whole genome sequences of three different serotypes of Lactococcus garvieae isolated from...

Background:Aeromonas hydrophila is a prevalent pathogenic bacterium in aquaculture that causes economic loss around the world. Antimicrobials are used to control and prevent the incidence of bacterial pathogens in aquaculture. However, they lead to the emergence of antimicrobial resistance strains...

Vibrio parahaemolyticus is one of the causes of acute hepatopancreatic necrosis disease or early mortality syndrome in shrimps. Frequent and repeated application of antibiotics leads to generating resistant strains. Bacteriophages and plant extracts are considered potential biological agents in...
