“…6 since they were tail water samples or effluent of WWTP. In general, the absolute abundances of 16S rRNA gene in coastal waters along coastline of China in this study were consistent with those in water of the Laizhou Bay (Li et al, 2018), but lower than 16S rRNA gene abundance in water of Duluth-Superior Harbor (LaPara et al, 2011) and water in two coastal areas (Geoje and Wando) of Korea (Germond and Kim, 2015). The absolute abundances of intI1 in coastal waters of this study were consistent with those in water of Duluth-Superior Harbor (LaPara et al, 2011).…”

“…Relative abundances of ARGs in Noth Yellow Sea previously reported (Na et al, 2014) were lower than those in the similar area of this study. Relative abundances of ARGs in waters of Frobisher Bay, Duluth-Superior Harbor, Geoje, Wando, and the Uwa Sea (Germond and Kim, 2015;LaPara et al, 2011;Neudorf et al, 2017;Suzuki et al, 2019) were also much lower than those in this study (Fig. 6b).…”

“…isolated from fish farms in Korea have been identified as a reservoir of tetracycline resistance genes (Kim et al ; Kim et al ). Studies have also found the prevalence of multi‐drug resistance including tetracyclines, sulfonamides, quinolones, β‐lactams, macrolides and intI1 encoded antibiotic resistance genes from coastal areas of Korea (Germond and Kim ; Jang et al ).…”

Aims: Manila clam (Ruditapes philippinarum) is one of the most popular seafood in Korea, owing to their unique taste and nutritional value. This study aimed to disclose the antibiotic and heavy metal resistance characteristics of Aeromonas spp. isolated from marketed Manila clam in Korea. Methods and results: A total of 36 Aeromonas spp. strains were isolated and subjected to two tests: an antibiotic disk diffusion test to determine their resistance to antibiotics, and a broth dilution test to determine their resistance to heavy metals. PCR-based amplification was performed to detect the resistance genes. A high level of resistance to ampicillin (100%) and cephalothin (89%) was observed, while 42, 39, 36 and 36% of the isolates were resistant to oxytetracycline, imipenem, nalidixic acid and tetracycline respectively. In addition, among the tested heavy metals, cadmium (Cd) recorded the highest resistance rate (61%), followed by chromium (Cr) (50%), lead (Pb) (47%) and copper (Cu) (37%). However, mercury (Hg) resistance was not observed. PCRs revealed the occurrence of bla TEM , bla SHV , bla CTX-M , qnrS, tetB, tetE, aac(6 0 )-Ib, strA-strB and intI1 genes among 100, 31, 31, 78, 78, 89, 25, 50 and 72% of the isolates respectively. Moreover, heavy metal resistance genes, copA, merA and czcA were detected in 25, 47 and 61% of the isolates respectively. Conclusions: The results suggest the importance of multi-drug and heavy metal-resistant aeromonads in Manila clam to assess the consumer safety and public health. Significance and Impact of the Study: This study is the first to elaborate on the importance of multi-drug and heavy metal-resistant aeromonads in Manila clam. Particularly, the presence of extended-spectrum-b-lactamase genes and other antibiotic resistance genes intensifies the possible health risks and may complicate therapeutic treatments upon infection, while heavy metal resistance suggests possible heavy metal exposure.
