Outer membrane proteins of Gram-negative bacteria play key roles in antibiotic resistance. However, it is unknown whether outer membrane proteins that respond to antibiotics behave in a specific manner. The present study specifically investigated the differentially expressed outer membrane proteins of an antibiotic-resistant bacterium, Edwardsiella tarda, a Gram-negative pathogen that can lead ...
Antibiotic contamination in agroecosystems may cause serious problems, such as the proliferation of various antibiotic resistant bacteria and the spreading of antibiotic resistance genes (ARGs) in the environment or even to human beings. However, it is unclear whether environmental antibiotics, antibiotic resistant bacteria, and ARGs can directly enter into, or occur in, the endophytic systems ...
Background and Aim: Bacterial resistance to antibiotics has made treatment difficult. The purpose of this study was to investigate bacterial species in patients with chronic rhinosinusitis after surgery of paranasal sinuses to determine antimicrobial resistance patterns of them. Materials and Methods: The data of 70 patients after paranasal sinuses surgery in Amiralmomenin hospital in Rasht ci...
Animal manure is commonly used as fertilizer for agricultural crops worldwide, even though it is believed to contribute to the spread of antibiotic resistance from animal intestines to the soil environment. However, it is unclear whether and how there is any impact of manure fertilization on populations and community structure of antibiotic-resistant endophytic bacteria (AREB) in plant tissues....
Bacteria causing infections in hospitalized patients are increasingly antibiotic resistant. Classical infection control practices are only partially effective at preventing spread of antibiotic-resistant bacteria within hospitals. Because the density of intestinal colonization by the highly antibiotic-resistant bacterium vancomycin-resistant Enterococcus (VRE) can exceed 10(9) organisms per gra...
Background and Objective: Acinetobacter baumannii is considered as an important agent in nosocomial infections. The problem facing the tratment of these bacteria is increasing resistance to antimicrobial agents such as carbapenems. The main mechanism of resistance to carbapenems in these bacteria is the presence of oxacillinases genes, which belong to class D betalactamases. The aim of this st...
The objective of this study was to evaluate collateral sensitivity and cross-resistance antibiotic-induced resistant Salmonella Typhimurium various antibiotics. S. ATCC 19585 (STWT) exposed ciprofloxacin, gentamicin, kanamycin, tetracycline induce antibiotic resistance, respectively, assigned as STCIP, STGEN, STKAN, STTET. susceptibilities the mutants cefotaxime, chloramphenicol, polymyxin B, s...
Abstract Background: Acinetobacter baumannii is an emerging pathogen of growing significance that has been more frequently isolated in nosocomial specimens. These bacteria have ability of gene transfer between its types and other bacteria as caused for resistance against antibiotics and resistance scattering of bacteria. The aim of this research is determination of resistance for antibiotics an...
The incidence of multiple antimicrobial resistance of bacteria which cause infections in the intensive care unit is increasing. These include methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci, penicillin-resistant Streptococcus pneumoniae and cephalosporin and quinolone resistant coliforms. More recently, pan antibiotic resistant coliforms, including carbapenems, ...
