“…Te previous study similarly demonstrated a high prevalence of E. coli resistance to TET in sardines and shrimps from Algeria [10]. In another study [12], E. coli isolates from major inland pollution sources (13.7%) and oysters (11.8%) in Korea had lower rates of TET resistance than did the isolates (25.6%) in the present study. Also, TET resistance (9.5%) of bacterial isolates from Nile tilapia farms in Egypt [30] was lower than that of E. coli isolates from the Korean aquaculture farms in this study.…”

The safety of seafood is a critical public health concern in Korea because of the high rate of raw seafood consumption. We investigated the prevalence and antimicrobial resistance of fecal-associated bacteria (Escherichia coli, Enterococcus faecium, Enterococcus faecalis, and Staphylococcus aureus) in 50 seawater samples and 48 aquatic animals collected from aquaculture farms along the Korean coast in 2018. Of them, E. coli was the most prevalent in seawater (24.0%) and aquatic animals (18.8%). Although more than 80.0% of E. coli isolates were sensitive to 9 of 15 antimicrobials, approximately 20.0% of the isolates were resistant to 4 antimicrobials, including tetracycline and streptomycin. Enterococcus spp. isolates (2.7–32.0%) were resistant to only 5 of 12 antimicrobials. Notably, 30.1% of E. coli isolates were resistant to three or more antimicrobials. To minimize health risks associated with raw seafood consumption, more research is needed concerning the prevalence and antimicrobial resistance of fecal indicators.

“…In particular, antimicrobial resistance has become a global public health priority [11,12]. Tis problem is attributed to the widespread and inappropriate use of antibiotics to prevent and treat bacterial infections in clinical settings, as well as in agricultural and aquaculture systems [13][14][15].…”

“…Indeed, E . coli isolates resistant to third/fourth/fifth generation cephalosporins were recovered from bivalves collected from the environment ( Al-Sarawi et al, 2018 ; Miotto et al, 2019 ; Divya et al, 2020 ; Jeong et al, 2021 ), moreover from bivalve molluscan shellfish purchased at the market ( Yu et al, 2020 ). In addition, ESBL producing E .…”

Bivalves are filter-feeding animals able to accumulate contaminants and microorganisms, either of marine or terrestrial origin. The aim of this study was to describe the prevalence of antimicrobial resistance (AMR) in bacterial isolates from bivalves using a systematic review of the literature. Comprehensive searches of MEDLINE, EMBASE, and Web of Science were carried out, based upon a registered protocol (PROSPERO), and following the preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines. The methodological quality of the included studies was assessed using a modified Hoy checklist. Meta-analyses of prevalence were carried out using random-effects models. In total, 103 articles were selected from 1,280 records and were included in the final analysis. The studies were from Asia (n = 54), Europe (n = 27), South and North America (n = 10 and n = 6, respectively), Africa (n = 2), Oceania (n = 1), and multicentre and intercontinental (n = 3). The meta-analysis of multiple antibiotic resistance (MAR) index revealed Aeromonas spp. as the genus with the highest prevalence of AMR (37%), followed by Vibrio spp. (34%), Salmonella spp. (18%), and Escherichia coli (15%). Resistance to third/fourth/fifth generation cephalosporins and fluoroquinolones, two highest priority, critically important antimicrobials (HPCIA), was recorded in approximately 10% of E. coli isolates. Resistance to carbapenems was very low (<2%) in Salmonella spp. and in E. coli, but was found in 5% of Vibrio spp. and in more than a third of Aeromonas spp. isolates. In aquatic bacteria, resistance to carbapenems was higher in Asian than in European isolates. Our study shows the presence of antibiotic resistant bacteria (ARB), including bacteria resistant to HPCIA, in marine bivalves, posing a risk for consumers.

“…The hazards associated with human pathogenic bacteria in products from aquaculture can be from indigenous bacteria, which are naturally present in the aquatic environment, and bacteria from anthropogenic contamination [ 20 ]. Shellfish-growing areas are increasingly affected by anthropogenic impacts, such as the release of agricultural run-off, untreated sewage effluents at outfall sites, and effluents of wastewater treatment plants, which may function as reservoirs of bacterial agents in marine environments [ 21 , 22 ]. It has been suggested that environmental pressures placed on marine habitats result in microbial dysbiosis, which is a key event in diseases in marine ecosystems [ 23 ].…”

Nocardia crassostreae is a novel pathogen responsible for infections in oysters (Crassostrea gigas) and mussels (Mytilus galloprovincialis). N. crassostreae is also responsible for nocardiosis both in immunocompetent and immunocompromised patients. We investigated N. crassostreae DNA in mussels grown in marine sites of the Mediterranean Sea in the Campania Region. We examined 185 mussel pooled samples by droplet digital PCR (ddPCR) and real-time quantitative PCR (qPCR), each pool composed of 10 mussels and 149 individual mussels. ddPCR detected N. crassostreae DNA in 48 mussel pooled samples and in 23 individual mussel samples. qPCR detected N. crassostreae DNA in six pooled samples and six individual mussel samples. The two molecular assays for the detection of N. crassostreae DNA showed significant differences both in the pooled and in individual samples. Our study demonstrated that ddPCR outperformed real-time qPCR for N. crassostreae DNA detection, thus confirming that ddPCR technology can identify the pathogens in many infectious diseases with high sensitivity and specificity. Furthermore, in individual mussels showing histological lesions due to N. crassostreae, the lowest copy number/microliter detected by ddPCR of this pathogen was 0.3, which suggests that this dose could be enough to cause infections of N. crassostreae in mussels.
