Evaluation of Antibiotic Resistance Pattern of Pathogenic Bacteria in the Yasooj Municipal Wastewater Treatment Plant
Background & objectives: Wastewater treatment plants represent one of the most important approachs for water conservation. On the other hand, wastewaters can act as a source of antibiotics in aquatic environments. The aim of this study was to evaluate the performance of the Yasooj municipal wastewater treatment plant for removal of Escherichia coli, Pseudomonas aeruginosa and Listeria monocytog...
متن کاملPredation and selection for antibiotic resistance in natural environments
Genes encoding resistance to antibiotics appear, like the antibiotics themselves, to be ancient, originating long before the rise of the era of anthropogenic antibiotics. However, detailed understanding of the specific biological advantages of antibiotic resistance in natural environments is still lacking, thus limiting our efforts to prevent environmental influx of resistance genes. Here, we p...
متن کاملOccurrence of Pathogenic Vibrios in Coastal Areas of Golestan Province in Iran
This study was carried out to investigate the occurrence of potentially pathogenic species of vibrio in sea water and estuarine environments of the Caspian Sea in the Golestan province of Iran. A total of 127 water samples from coastal waters as well as from river and estuaries were collected and analyzed by culture, during April and September 2001. Following prompt centrifugation, the resusp...
متن کاملAntibiotic resistance conferred by conjugative plasmid in Escherichia coli isolated from community ponds of Kathmandu Valley.
Bacteria can develop a variety of cellular mechanisms for acquiring resistance against antibiotics, including genetic mechanisms. Both commensal and pathogenic bacteria become resistant to every new antibiotic within few years of introduction. In recent years, antibioticresistant bacteria are being widely spread in nature. This can be due to the irrational use of sub-lethal concentrations of an...
متن کاملPyomelanin produced by Vibrio cholerae confers resistance to predation by Acanthamoeba castellanii
Protozoan predation is one of the main environmental factors constraining bacterial growth in aquatic environments, and thus has led to the evolution of a number of defence mechanisms that protect bacteria from predation. These mechanisms may also function as virulence factors in infection of animal and human hosts. Whole transcriptome shotgun sequencing of Vibrio cholerae biofilms during preda...
