Antimicrobial resistance of Aeromonas hydrophila isolated from different food sources: A mini-review

Abstract

Aeromonas hydrophila is a Gram-negative, oxidase-positive, facultative, anaerobic, opportunistic aquatic pathogen. A. hydrophila produces virulence factors, such as hemolysins, aerolysins, adhesins, enterotoxins, phospholipase and lipase. In addition to isolation from aquatic sources, A. hydrophila has been isolated from meat and meat products, milk and dairy products, and vegetables. However, various studies showed that this opportunistic pathogen is resistant to commercial antibiotics. This is attributed to factors such as the indiscriminate use of antibiotics in aquaculture, plasmids or horizontal gene transfer. In this report, we highlight the occurrence, prevalence and antimicrobial resistance of A. hydrophila isolated from different food samples. The presence of antimicrobial-resistant A. hydrophila in food poses threats to public and aquatic animal health.

Aeromonas hydrophilafrom marketed mullet (Mugil cephalus) in Egypt: PCR characterization ofβ-lactam resistance and virulence genes

“…(). While we identified that only 14% of the isolates possessed bla OXA , other studies reported higher percentages as reviewed previously (Stratev and Odeyemi ). Our findings also identified bla CTX‐M , which is responsible for the hydrolysis of CTX, only in 24% of the isolated A. hydrophila .…”

“…The resistance of A. hydrophila isolated from freshwater fish to antimicrobial agents differs among various studies (Stratev and Odeyemi ). However, it is difficult to compare our results with that obtained in other studies from Egypt due to the dearth of information about antimicrobial resistance of A. hydrophila from mullet.…”

Comparison of bacterial densities and resistance in different beach compartments: should water be our main concern?

“…É muito importante monitorar bactérias patogênicas em áreas de praia porque a propagação da poluição nas zonas de banho está diretamente ligada à saúde dos banhistas de mar, tornando a poluição um importante problema de saúde pública 24 . 32 . Desta forma, foram observadas densidades maiores dessas bactérias patogênicas, especialmente em sedimentos e mexilhões, e uma parte representativa dessas cepas foi resistente a muitos antibióticos.…”

“…Over the years, resistance to Cephalosporins among members of Enterobacteriaceae has increased mainly due to the spreading of Extended-spectrum B-Lactamases (ESBL) and others antibiotics 29 . The presente study corroborate with this results since it was isolated a siginificant number of E. coli strains resistance to Vancomicin, Erytromicin and Fosfomicin.…”

“…The use of antibiotics is one of the most important factors influencing the emergence of resistance in bacterial pathogens. Multiresistant Aeromonas were isolated from different parts of the world and are reported to be resistant to penicillin and Ampicillin, but sensitive to Aminoglycosides, Tetracycline, Chloramphenicol, TrimethoprimSulfamethoxazole, Quinolones, and secondand third-generation Cephalosporins 32 . In this way, it was seen higher densities of these pathogenic bacteria especially in sediment and mussels, and a representative part of these strains were resistance to many antibiotics.…”
