Abstract Background and Objective: The prevalence of different bacterial species and antibiotic resistance varies according to geographical conditions. Hence, we aimed to identify the prevalence of bacterial agents isolated from the urine culture and also investigate the antibiotic susceptibility of bacteria. Material and Methods: This cross-sectional study conducted on 7200 urine samples to id...
Evolution of bacteria towards resistance to antimicrobial drugs, including multidrug resistance, is unavoidable because it represents a particular aspect of the general evolution of bacteria that is unstoppable. Therefore, the only means of dealing with this situation is to delay the emergence and subsequent dissemination of resistant bacteria or resistance genes. Resistance to antimicrobial dr...
Antibiotic resistance is a major concern, yet it is unclear what causes the relatively high densities of resistant bacteria in the anthropogenically impacted environment. There are various possible scenarios (hypotheses): (A) Input of resistant bacteria from wastewater and agricultural sources is significant, but they do not grow in the environment; (B) Input of resistant bacteria is negligible...
conclusions thirty-three bacterial strains; 10 strains of e. coli, 10 strains of s. flexneri, 3 strains s. sonnei, 2 strains of s. serovar newport, and 7 strains of p. aeruginosa, were isolated and identified from nile water and ground water in sohag governorate. the prevalence of enteric bacteria in water sources in studying area was considerable. no clear or distinct correlation could be conc...
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...
Background: The increasing emergence of antimicrobial resistance among gram negative bacteria especially Enterobacteriaceae has become a global problem. Klebsiella pneumoniae is an opportunistic pathogen, which recently due to causing broad spectrum of disease and antibiotic resistance has been lionized. Efflux pumps are one of the antibiotic resistance mechanisms, which were introduced in t...
Background & Objective: Klebsiella pneumoniae has received attention due to a wide range of diseases and antibiotic resistance.The resistance to fluoroquinolones in gram-negative bacteria is often due to chromosomal mutations in the gyr and par genes. This research aimed at investigating the pattern of fluoroquinolone resistance and its relation with a mutation in the parC gene among clinical i...
Background & Aims: The increasing rate of antibiotic resistant bacteria in different wards of hospitals, especially in the intensive care units and increasing rates of morbidity and mortality due to these bacteria, highlights the need for awareness of antibiotic resistance patterns. The aim of this study was to determine the antibiotic resistance patterns of microorganisms isolate...
