“…Two virulence-related genes, wecC and xtmA were only present in strains from the diseased fish. In a different study, C. maltaromaticum isolated from arctic char (Salvelinus alpinus) and lake white fish (Coregonus clupeaformis) showed sensitive susceptibility towards tetracycline MIC50 (μg/μl) and resistant to ampicillin MIC50 (μg/μl) [35]. This is contradicting to C. maltaromaticum strain AM47e which was sensitive to ampicillin (10 μg).…”

Acaudina molpadioides or locally known as ‘beronok’ is a high valued sea cucumber that is widely distributed in the muddy shores in the west coast Peninsular Malaysia and being consumed by the local people as traditional healthy delicacies. They are made into dishes and are usually consumed raw as ‘kerabu’. The aim of this study was to isolate and characterise the bacteria and fungus from the intestine of A. molpadioides using standard method for biochemical tests, safety assessments and molecular identification. A total of 100 samples were obtained randomly from Pulau Langkawi, Malaysia and 1642 isolates were obtained from the intestine. Biochemical tests, safety evaluation and molecular identification were performed. Six strains (AM8h, AM47e, AM59a, AM67d, AM80d, and AM84d1) were selected for characterisation as they showed distinct morphology and from the biochemical tests. Further molecular identification showed the strains were identified as Priestia megaterium, Carnobacterium maltaromaticum, Bacillus tropicus, Staphylococcus saprophyticus, Bacillus cereus, and Yarrowia lipolytica (GenBank accession number: MZ947169, MZ934727, MZ947170, MZ934728, MZ934726, and MZ956769). The results indicated that both bacteria and fungus were presence in the intestine of A. molpadioides, hence there is a need for adequate measures in consuming this sea cucumber raw.

“…79,80 In the Nunavut region, the presence of multiple resistance to two or more antibiotics, including ampicillin and streptomycin, has been identified in two salmonid isolates taken from remote locations away from human habitats. 81 Wild animals can act as vectors and spread antimicrobial resistance from urban rural areas in Arctic environments, as exemplified by Alaskan seagulls carrying antibiotic resistance strains of E. coli. 82,83 Human-environment interactions may pose a risk of exposure to wastewater-related pathogens through contact with animals or the aquatic environment, especially as natural wastewater treatment systems (WWTSs) are located close to households.…”

The increasing prevalence of antibiotic resistance is a global problem in human and animal health. This leads to a reduction in the therapeutic effectiveness of the measures used so far and to the limitation of treatment options, which may pose a threat to human health and life. The problem of phenomenon of antibiotic resistance affects more and more the polar regions. This is due to the increase in tourist traffic and the number of people staying at research stations, unmodernised sewage systems in inhabited areas, as well as the migration of animals or the movement of microplastics, which may contain resistant bacteria. Research shows that the presence of antibiotic resistance genes is more dominant in zones of human and wildlife influence than in remote areas. In a polluted environment, there is evidence of a direct correlation between human activity and the spread and survival of antibiotic-resistant bacteria. Attention should be paid to the presence of resistance to synthetic and semi-synthetic antibiotics in the polar regions, which is likely to be correlated with human presence and activity, and possible steps to be taken. We need to understand many more aspects of this, such as bacterial epigenetics and environmental stress, in order to develop effective strategies for minimizing the spread of antibiotic resistance genes. Studying the diversity and abundance of antibiotic resistance genes in regions with less anthropogenic activity could provide insight into the diversity of primary genes and explain the historical evolution of antibiotic resistance.

“…It also leads to the dissemination of mesophilic and antibiotic-resistant microbes into the polar environment. The warming temperature in the region may enhance survival and overrule the native microbiome of the Arctic (Moniz et al, 2021). The survival of such allochthonous microbes in the Arctic has a signi cant role in public health (Chandran et al, 2011).…”

The Arctic is losing its pristine nature due to the increased warming and human activities in the region. This may lead to the introduction of mesophilic and antibiotic-resistant bacteria (ARB) into the environment. The warming trend in the Arctic will support those bacteria to thrive in the environment. The horizontal gene exchange mechanism in the bacteria will lead to an exchange of antibiotic-resistant genes with the environmental microbes. Migratory birds have a significant role in the dissemination of pathogenic and ARB into the Arctic. In this study, the survival of pathogenic and multidrug-resistant mesophilic bacteria, E. coli isolated from migratory birds, Barnacle goose was carried out. In-situ microcosm studies were carried out in the Arctic during the summer (2017) and fall (2018) to evaluate the survival of the bacteria in the environments. In addition, this study also tested the factors such as biological, chemical, and physical parameters that determine the survival of E.coli in the Arctic waters. In the Arctic summer, the removal of the bacteria is mainly influenced by biological factors and solar radiation during summer and prolonged survival of E.coli during the fall season.
