Antibiotic Resistance Genes in Klebsiella pneumoniae and Heavy Metal Contamination in Tilapia (Oreochromis niloticus): A Public Health Risk Assessment in Bangladesh

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Species‐specific 16S‐23S ITS and antibiotic resistance IntI, blaCTX‐M, blaTEM and blaSHV genes of Klebsiella pneumoniae were detected, and most of the isolates were multidrug‐resistant. Target hazard quotient values of Fe for >1 revealed a higher level of hazard index. Target cancer risk values of Fe exceeded the recommended value (<10−4).

Effects and Molecular Regulation Mechanisms of Salinity Stress on the Health and Disease Resistance of Grass Carp

Frontiers in Immunology, 2022
Though some freshwater fish have been successfully cultivated in saline-alkali water, the survival rates of freshwater fish are greatly affected by different saline-alkali conditions. The mechanisms of immune adaptation or immunosuppression of freshwater

Metabarcoding Reveals a Potentially Undescribed Columnaris‐Causing Bacterium in Peracute Skin Disease of Rainbow Trout (Oncorhynchus mykiss, Walbaum)

Journal of Fish Diseases, Volume 49, Issue 1, January 2026.
ABSTRACT Columnaris‐causing bacteria (CCB) represent a group of four Flavobacterium species, previously classified under Flavobacterium columnaris, causing a threatening condition in salmonid farming characterised by cutaneous and gill lesions, commonly referred to as ‘saddleback disease’. A peracute skin disease outbreak with high mortality in rainbow

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts
