The aim of this study was to evaluate the antimicrobial susceptibility profile of Aeromonas sp., and Escherichia coli isolated from samples of yellow hake (Cynoscion acoupa). We analyzed 53 Aeromonas spp. and four E. coli isolates. We observed increased resistance of E. coli to levofloxacin and sulfa-trimethoprim as well as resistance of Aeromonas spp. to ampicillin, amoxicillin-clavulanate, cefuroxime, and cefotaxime. The multiple antimicrobial resistance(MAR) index indicated multidrug resistance in 90.54% (n=48) of Aeromonas spp. isolates and in 50% (n=2) of E. coli isolates. One strain of Aeromonas spp. was resistant to all 11tested antimicrobials (MAR index = 1.00). In vitro,piperacillin + tazobactam was the most effective antimicrobial for E. coli,and cefepime and levofloxacin were the most effective antimicrobials for Aeromonas spp. Therefore, in case of illnesses caused by these microorganisms, these antimicrobials should be used. The multidrug resistance of Aeromonas spp. and E. coli in this study is elevated. This is worrisome considering the increase in bacteria resistant to multiple drugs, reducing the options for successful clinical antimicrobial use.

Aim: Aeromonas spp. are common members of water and wastewater microbiomes but some are listed as opportunistic pathogens and are often reported to carry antimicrobial resistance (AMR) genes. We aimed to assess the performance of isolation media for capturing their distribution and their role in AMR dissemination into aquatic environments.

Objectives: The severity of the diarrhea disease is exacerbated by co-infections that involve Enterotoxigenic Escherichia coli (ETEC) and other enteric pathogens, which complicate the diagnosis and treatment. This study explores the prevalence, clinical manifestations, and risk factors of ETEC and its co-infections in Dhaka, Bangladesh.
Methods: The study used data from the Diarrheal Disease Surveillance System at Dhaka Hospital, involving 16,276 patients from 2017-2022.

The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed. However, infectious diseases present major challenges to its cultivation, as pejerrey is susceptible to diverse pathogens, including bacteria, fungi and parasites.

Polymyxin antibiotics B and colistin are considered drugs of last resort for the treatment of multi-drug and carbapenem-resistant Gram-negative bacteria. With the emergence and dissemination of multi-drug resistance, monitoring the use and resistance to polymyxins imparted by mobilised colistin resistance genes () is becoming increasingly important. The genus is widely disseminated throughout the environment and serves as a reservoir of -3, posing a significant risk for the spread of resistance to polymyxins.
