Abstract

Antibiotic resistance has become a primary global health concern, affecting humans and animals. In the case of the fish population, Aeromonas is the most commonly found antibiotic-resistant pathogen and has emerged as a critical public health concern. Aeromonas species act as primary pathogens in fish and are widely present in fresh and brackish water environments. The majority of Aeromonas species exhibit resistance to a wide range of antibiotics. To prevent human infections, particularly those that affect fishermen, it is crucial to comprehend the incidence of Aeromonas and the patterns of antibiotic resistance. Hence, this study investigated antibiotic resistance patterns in the Aeromonas species isolated from freshwater fishes collected from various farm ponds. Instead of relying on antibiotics, treating infected fish with probiotics can reduce the risk of human fish-borne infections, enhance fish health, and antibiotic abuse can be decreased. A global effort is needed to reduce the overuse of antibiotics in aquaculture and encourage stakeholders to adopt preventive measures for disease control. This review article aims to provide an updated understanding of antibiotic resistance patterns in Aeromonas isolated from freshwater fish and assess their potential impact on human health. Additionally, by summarizing recent research findings, this study emphasizes the steps that must be followed to build management strategies and achieve successful control.
