Detection of Plasmids in Heavy Metal Resistance Bacteria Isolated from the Persian Gulf and Enclosed Industrial Areas
Several heavy metal resistant bacterial strains were isolated from sediment and water samples collected from the Persian Gulf and enclosed industrial areas. All the isolated bacteria were identified by 16S rRNA gene sequencing. Isolated bacteria were tested for the presence of plasmids using the modified alkaline lysate method. The method was effective for identification and characterization of...
متن کاملNew update on molecular determinants of colistin resistance in bacteria
Colistin relates to the polymyxin group of antibiotics. This antibiotic is still used to destroy gram-negative bacteria as a last resort. However, resistance to this antibiotic has been reported and is appearing day by day. Not much information is available on the exact mechanisms of resistance to this antibiotic. Also, not enough information about pharmacokinetics and pharmacodynamics is avail...
متن کاملAntibiotic Resistance Pattern of Gram-Negative Bacteria in Gorgan
Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...
متن کاملHeavy metal resistance genes and proteins in bacteria and their application.
Introduction Bacteria may carry determinants of resistance to a number of heavy metals, including silver, bismuth, cadmium, cobalt, copper, mercury, lead, nickel, thallium or zinc cations and the oxyanions of arsenic, chromium, antimony, tellurium or tungsten. Such resistance determinants have been reviewed extensively [ 1-41. Bacterial resistance to heavy metals is conferred by specific resist...
متن کاملDistribution of horizontally transferred heavy metal resistance operons in recent outbreak bacteria
Mankind is confronted by the outbreaks of highly virulent and multi-drug resistant pathogens. The outbreak strains often belong to well-known diseases associated species such as Salmonella, Klebsiella and Mycobacterium, but even normally commensal and environmental microorganisms may suddenly acquire properties of virulent bacteria and cause nosocomial infections. The acquired virulence is ofte...
