چکیده

The Pseudomonas R factor RP1 determines an inducible tetracycline resistance similar to that described for Escherichia coli R factors. The level of RP1-determined resistance measured by minimal inhibitory concentration testing is dependent on the host bacteria and corresponds to the magnitude of decrease in tetracycline accumulation by RPl-containing organisms. The tetracycline resistance mechanism is inactivated at low temperatures. The effect of metabolic inhibitors on tetracycline accumulation by susceptible organisms under various conditions indicates a possible nonspecific effect of cellular energy metabolism on tetracycline uptake.

Multidrug Resistance in Infants and Children

Bacterial infections may cause disease and death. Infants and children are often subject to bacterial infections. Antimicrobials kill bacteria protecting the infected patients andreducing the risk of morbidity and mortality caused by bacteria. The antibiotics may lose their antibacterial activity when they become resistant to a bacteria. The resistance to different antibiotics in a bacteria is ...

میزان آلودگی و مقاومت آنتی بیوتیکی باکتری های گرم منفی جدا شده از بیماران در بخش های مختلف بیمارستان های توحید و بعثت شهر سنندج طی سال های 1392-1393

Introduction: Antibiotic resistance survey in Gram-negative bacteria has an important role in the management of treatment. The aim of this study was to evaluate antibiotic resistance of Gram-negative bacteria isolated from patients and determination of contamination rate of different wards of hospital to these bacteria. Methods: Information of 3242 patients from hospital information system o...

Transformation of Pseudomonas putida and Escherichia coli with plasmid-linked drug-resistance factor DNA.

Conditions optimal for the transformation of Pseudomonas putida and E. coli with a drug-resistance factor (RP 1) DNA, which specifies resistance to carbenicillin, tetracycline, kanamycin, and neomycin, are described. The transformants retain all the fertility, incompatibility, and drug-resistance characteristics present in the parent. Covalently-closed circular molecules of almost identical con...

Characteristics of two broad spectrum antibiotics produced by Mycoplasma sp. RP III.

Two extracellular antibiotics produced by Mycoplasma sp. RP III growing in serum-containing media have been purified by solvent extraction and ion-exchange chromatography. Factor I inhibits Gram-positive and Gram-negative bacteria in vitro and a crude preparation protected mice from Pseudomonas and Straphylococcus infections; it is of low cytotoxicity. Factor II, a lipid, inhibits Gram-positive...
