Abstract
Antibiotics are intensively used in various sectors, such as human and animal husbandry, and in the current scenario, they are considered global contaminants in different environmental compartments. Constant antibiotic exposure leads to antimicrobial resistance in environmental microorganisms. However, the correlation between antibiotic exposure and resistance is still indistinct and unproven in environmental microbiota. The release of antibiotic-resistant bacteria from municipal wastewater into rivers poses a public health concern. This study aimed to explore the antibiotic resistance profiling of bacterial pathogens isolated from wastewater, sludge, water, and sediment samples of the Ganges River of three North Indian cities (Kanpur, Prayagraj and Varanasi) for summer and winter seasons. Antibiotic resistance profiles were done for 12 antibiotics through the disc diffusion method. PCR analysis of genomic and plasmid DNA, the prevalence of six Antibiotic Resistance Genes was evaluated in 103 bacterial isolates isolated from wastewater, sludge, river water and sediment samples of North Indian cities. This study gives insight into the role of wastewater treatment plants in the abundance and spread of antibiotic-resistant bacteria and genes through effluent in the receiving river environment. The consumption of antibiotics is very high in India, and Antibiotic Resistance Genes are mostly abundant in wastewater treatment plants and river water and sediment, which indicates that the river has the potential and probable reservoir of Antibiotic Resistance Genes.
期刊介绍:
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
