“…Aeromonas was also one of the most prevalent genera among resistant isolates from fish with the highest prevalence being A. sobria . This species already is known as a causative agent of fish diseases (Coscelli, Casabonne, Morón‐Alcain, Arancegui, & Vigliano, ). Another agent of fish diseases detected in our study was A. salmonicida , which causes bacterial furunculosis and septicaemia in variety of fish.…”

Aquatic environments are one of the most favorable settings for acquisition and dissemination of antimicrobial resistance. The aims of this study were twofold: (1) to isolate and identify antimicrobial resistant Gram-negative bacteria that are prevalent in fish kept in open aquaculture ponds and(2) to analyse their antimicrobial resistance profiles. One hundred and nineteen isolates from fish resistant to at least one antimicrobial were investigated. The most predominant genera were Pseudomonas, Chryseobacterium, Enterobacteriaceae, and Aeromonas. The highest numbers of multiresistant isolates were found within Pseudomonas spp., and the lowest, in Aeromonas spp.Resistance to beta-lactams was the most common among all of the bacterial genera. The absence or very low rates of resistance to fluoroquinolones, the small number of clinically important resistance genes, and bacterial taxonomic composition suggest that the most widespread resistant bacteria in aquacultured fish are autochthonous microbiota. Practical applicationsThe majority of antimicrobial resistant bacteria that are prevalent in aquacultured fish from open ponds can be treated as natural (autochthonous microbiota). In this study, only a minority of resistant bacteria detected in fish could be associated with polluted waters originating from animal farms or human healthcare facilities. Some strains, particularly the family Enterobacteriaceae that is found in fish, contain clinically important resistance determinants that potentially can be transmitted to human microbiota in cases of inappropriate processing of fish intended for food. With regard to antimicrobial resistant bacteria, measures for control of inflowing waters to aquaculture ponds should be taken in addition to monitoring fish microbiota and its' resistance should be investigated on a regular basis.

“…Aeromonasis in fish is caused by Aeromonas species, namely A. hydrophila , A. salmonicida , A. caviae , A. sobria , A. veronii and A. jandaei [ 9 , 10 , 11 ]. These species are common in freshwater habitats and are frequently associated with severe infections and mortality in various freshwater and marine fish [ 12 , 13 , 14 , 15 ].…”

Bacteriophages in the Control of Aeromonas sp. in Aquaculture Systems: An Integrative View

et al. 2022

Aeromonas species often cause disease in farmed fish and are responsible for causing significant economic losses worldwide. Although vaccination is the ideal method to prevent infectious diseases, there are still very few vaccines commercially available in the aquaculture field. Currently, aquaculture production relies heavily on antibiotics, contributing to the global issue of the emergence of antimicrobial-resistant bacteria and resistance genes. Therefore, it is essential to develop effective alternatives to antibiotics to reduce their use in aquaculture systems. Bacteriophage (or phage) therapy is a promising approach to control pathogenic bacteria in farmed fish that requires a heavy understanding of certain factors such as the selection of phages, the multiplicity of infection that produces the best bacterial inactivation, bacterial resistance, safety, the host’s immune response, administration route, phage stability and influence. This review focuses on the need to advance phage therapy research in aquaculture, its efficiency as an antimicrobial strategy and the critical aspects to successfully apply this therapy to control Aeromonas infection in fish.

“…Aeromonas sobria (A. sobria) have been reported to affect various farmed and wild fish species, such as tilapia (Oreochromis sp. ), perch (Perca fluviatilis), walking catfish (Clarias batrachus), common carp (Cyprinus carpio), rainbow trout, wild-spawning gizzard shad, (Dorosoma cepedianum), and mud loach (Misgurnus mizolepis) [9,10]. The clinical signs of the disease caused by A. sobria infection in fish include ulcerative dermatitis, tail and fin rot, and septicemia [11].…”

In recent times, nutraceuticals have been used extensively to identify promising feed additives for the improvement of the aquaculture industry through the enhancement of growth and survival rates, potentiation of the immune responses, and fortification of the resistance against infectious bacterial diseases. In this study, Nile tilapia (Oreochromis niloticus) were fed with diets supplemented with quinoa seeds (QU) or prickly pear fruit peel (PP) at the dose levels of 10% or 20% of the diet. After 45 days of the feeding trial, the fish were exposed to Aeromonas sobria (A. sobria) challenge. The pre-challenge indices indicated that both supplements mediated a significant improvement in most of the estimated parameters, including survival rate, antioxidant status, hematological and immunological indices, and hepatoprotective potential. These effects were recorded in the groups fed with high doses of the supplements (20%). The least changes were observed in the QU10-supplemented fish. In the spleen tissue, the TGF-β gene was upregulated in the PP10-, PP20- and QU20-supplemented groups, while the expression of the IFN-γ gene remained unaffected in all the supplemented groups, except for the PP20-supplemented group, which showed an upregulation. After the challenge with A. sobria, the relative survival percentage was improved by the supplementation of PP and QU, particularly in the PP20-supplemented group, possibly via the promotion of immunological responses, hepatoprotective potency, and modulation of the studied genes. Moreover, the morphological structure of the tissues showed marked recovery. The findings suggest that Nile tilapia fed with different levels of PP peel and QU seeds, particularly at the level of 20%, enhanced the immune response in fish and improved their resistance against A. sobria infection.
