{"doi":"10.3389/fpubh.2021.692166","title":"Dynamics, Diversity, and Virulence of Aeromonas spp. in Homestead Pond Water in Coastal Bangladesh","abstract":"Aeromonads are aquatic bacteria associated with frequent outbreaks of diarrhea in coastal Bangladesh, but their potential risks from environmental sources have remained largely unexplored. This study, over 2 years, examined homestead pond waters in the region for monthly dynamics and diversity of Aeromonas spp. The bacterial counts showed bi-modal annual growth peak, pre- and post-monsoon, strongly correlating ( p < 0.0005) with temperature. Of 200 isolates characterized, Aeromonas veronii bv. sobria (27%) was predominant among co-existent Aeromonas schubertii (20%), Aeromonas hydrophila (17%), Aeromonas caviae (13%), and three more. PCR screening of virulence-related genes identified 15 genotypes (I to XV), however, enterotoxigenicity in animal model was observed for five genotypes, ca. 18% (nine of 50) strains, prevalent in A. veronii bv. sobria, A. hydrophila , and A. caviae . Pathogenic strains were distinguishable by possessing at least three of the major virulence genes: ascV, hlyA, ela, ast , and alt , together with accessory virulence factors. PFGE of Xba I-digested genomic DNA revealed high genetic diversity and distant lineage of potentially toxigenic clones. Therefore, along with increased global warming, Aeromonas spp. having multi-factorial virulence potential in coastal ponds that serve as drinking water sources pose a potential health risk, and underscores the need for routine monitoring.","journal":"Frontiers in Public Health","year":2021,"id":160713,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":33,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.951,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":674077,"name":"Sucharit Basu Neogi","orcid":"0000-0001-9917-5983","position":1,"is_corresponding":false},{"id":674708,"name":"Tanvir Bashar","orcid":null,"position":2,"is_corresponding":false},{"id":326098,"name":"Marzia Sultana","orcid":"0000-0002-0862-6919","position":3,"is_corresponding":false},{"id":674709,"name":"Fatema‐Tuz Johura","orcid":null,"position":4,"is_corresponding":false},{"id":78289,"name":"Saiful Islam","orcid":"0000-0001-5777-9164","position":5,"is_corresponding":false},{"id":264089,"name":"Nur A.
