The influence of bacteriocins on resistance to infection by gram-negative bacteria

The Influence of Bacteriocins on Resistance to Infection by Gram-negative Bacteria. I. the Effect of Colicin on Bactericidal Power of Blood.

Antibiotic 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...

3 Molecular Evolution of Bacteriocins in Gram-Negative Bacteria

The study of molecular evolution has become a valuable tool in understanding the origin of life and the speciation of organisms, with the focus on changes in DNA and protein sequence and their functions. Interest in studying the molecular evolution of bacteriocins, the narrow-spectrum peptide antimicrobials, was elicited due to the broad diversity and abundance of these proteins. The availabili...

Bacteriocins of gram-positive bacteria.

In recent years, a group of antibacterial proteins produced by gram-positive bacteria have attracted great interest in their potential use as food preservatives and as antibacterial agents to combat certain infections due to gram-positive pathogenic bacteria. They are ribosomally synthesized peptides of 30 to less than 60 amino acids, with a narrow to wide antibacterial spectrum against gram-po...

Frequency of Multi-Drug Resistance (MDR) in Gram Negative Bacteria from Urinary Infection in Gorgan, 2011-12

Abstract Background and objective: The periodic evaluation of antimicrobial activity of different antibiotic is essential because antibiotic sensitivity pattern may also changed during short courses. The aim of this study was to assess the frequency of Multi-drug Resistance (MDR) in Gram negative uropathogens. Material and Methods: This study was conducted on 111 gram negative uropatho...
