In total, 151 Escherichia coli isolates from Ruditapes philippinarum in Gomso Bay were analyzed for their susceptibility to 18 different antimicrobial agents and for genes associated with virulence. For virulence genes, each strain of the isolates was positive for the enterotoxigenic E. coli (ETEC)-specific heat-stable toxin (estA), enteroinvasive E. coli (EIEC)-specific invasion-associated locus (iaa) gene and enteropathogenic E. coli (EPEC)-specific attaching and effacing (eae) gene. According to a disk diffusion susceptibility test, resistance to ampicillin was most prevalent (23.2%), followed by resistance to amoxicillin (22.5%), ticarcillin (20.5%), tetracycline (18.5%), nalidixic acid (12.6%), ciprofloxacin (10.6%), streptomycin (9.9%), and chloramphenicol (6.6%). More than 35.8% of the isolates were resistant to at least one antimicrobial agent, and 19.9% were resistant to four or more classes of antimicrobials; these were consequently defined as multidrug resistant. Minimum inhibitory concentration (MIC) ranges for the antimicrobial resistance of the 15 different antimicrobial agents of 54 E. coli strains were confirmed by varying the concentrations from 32-2,048 µg/mL. Overall, these results not only provide novel insights into the necessity for seawater and R. philippinarum sanitation in Gomso Bay but they also help to reduce the risk of contamination by antimicrobial-resistant bacteria.

“…Greater than 40% of tetracycline-resistant E. coli was reported broiler production. Previous studies reported tetracyclines are the most-frequency used in poultry production as prophylaxis, antibacterial therapy, and growth promoter (Kim et al, 2013;Ljubojević et al, 2017;Roth et al, 2019). Similarly, the prevalence of tetracycline resistance was high in pig and vegetable samples (Pu et al, 2018).…”

“…E. coli isolates were observed high resistance to tetracycline (92%) and trimethoprim (80%) (Odumosu et al, 2021). Resistant E. coli isolated from shellfish farms were found in tetracycline (30%), streptomycin (26%), and trimethoprim (14%) (Park et al, 2013). Salmonella isolates from seafood were high resistance to sulfonamides (57%), followed by tetracycline (34%) and streptomycin (29%), and 43% of resistant isolates were MDR bacteria (Zhang et al, 2015).…”

The raising and spreading antimicrobial resistance (AMR) bacteria in humans, animals, and�environment is a serious global public health issue. Improper use of antimicrobial agents can promote resistant bacteria, and as a result, they can circulate in the environment. Contamination of AMR in the environment can increase the risk of AMR distribution in humans, animals, and the environment. Monitoring and surveillance of AMR in the environmental sector are limited compared to animal and human sectors. The objectives of this study were to determine phenotype and genotype of AMR and extended-spectrum beta-lactamase (ESBL) production in�Escherichia coli�and�Salmonella�isolated from cultivated oysters and estuarine waters, to examine serovars of�Salmonella�isolates, and to detect virulence genes in�E. coli�and�Salmonella�isolated from cultivated oysters (n=144) and estuarine water (n=96).�E. coli�(n=409) and�Salmonella�(n=126) isolates were obtained from cultivated oysters and estuarine waters from Phang Nga, Thailand. The predominant serovars of�Salmonella�were Paratyphi B (13.50%), followed by Eastbourne (12.70%), and II (15.87%). The resistance to at least one antimicrobial agent was found in�E. coli�(94.13%) and Salmonella (96.82%). The multidrug resistance�E. coli�(42.60%) and�Salmonella�(23.02%) were observed. The�blaTEM�(31.55%),�tet(A)�(25.44%), and�strA�(14.92%) were the most prevalent resistance genes found in�E. coli�isolates, while sul3�(14.29%),�blaTEM�(11.91%), and�cmlA�(11.91%) were commonly found in resistance�Salmonella. Phenotypic ESBL production was detected in eight�E. coli�isolates from estuarine waters, and two�Salmonella�isolates from oysters. One of E. coli�and�Salmonella�isolates that harbored�blaTEM-1�corresponded to broad-spectrum beta-lactamase. However,�four� E. coli�isolates harbored�blaCTX-M�genes. The most common virulence genes of�E. coli�isolates were�istx1�(17.85%) and�lt�(11.74%).�For�Salmonella�isolates,�high prevalence of�invA�(76.98%),�stn�(76.98%), and�fimA�(69.05%) were observed. The�E. coli�isolates that resistant to ampicillin were resistant to chloramphenicol and trimethoprim (p<0.0001).�Furthermore, the�E. coli�isolates harboring�stx1�and�stx2�were more likely to�resistant to chloramphenicol than those did not contain virulence genes (p<0.0001). The�Salmonella�isolates that consisted of�invA�and�fimA�were more likely to be resistant to various antibiotics, including ampicillin, chloramphenicol, tetracycline, and trimethoprim. In conclusion, oysters and estuarine water are one of the potential AMR hotspots in the environment. Therefore, continuing monitoring and surveillance of AMR should be implemented in the environment.

A total of 423 shellfish (Oysters, Crassostrea gigas; short-necked clams, Ruditapes philippinarum and corb shells, Cyclina sinensis) were collected from the west coast of Korea, from which 277 Escherichia coli strains were isolated. The antimicrobial susceptibility patterns of isolated strains were analyzed for 22 antimicrobial agents used in Korea for clinical or veterinary therapy. The resistance of E. coli isolates to ampicillin (37.2%) was highest, followed by cephalothin (21.7%), cefazolin (19.9%), trimethoprim (15.2%). Antimicrobial resistance was present in 56.7% of E. coli isolates against at least one antimicrobial agent. Of 277 isolates, 44 (15.9%) were resistant to multiple antimicrobial agents.
