Background and Objective. Antimicrobial resistance is now a major challenge to clinicians for treating patients. Hence, this short term study was undertaken to detect the incidence of multidrug-resistant (MDR), extensively drug-resistant (XDR), and pandrug-resistant (PDR) bacterial isolates in a tertiary care hospital. Material and Methods. The clinical samples were cultured and bacterial strai...
Multi-drug resistance has become a major problem for the treatment of pathogenic bacterial infections. The use of bacteriophages is an attractive approach to overcome the problem of drug resistance in several pathogens that cause fatal diseases. Our study aimed to isolate multi drug resistant bacteria from patients with septic wounds and then isolate and apply bacteriophages in vitro as alterna...
introduction: drug resistant staphylococci are the most important agents of nosocomial infections. in this survey, effect of different antibiotics on these bacteria and their drug resistance was investigated. methods: the study included 500 strains of staphylococci. minimum inhibitory concentrations of all antibiotics was determined by the broth macro dilution technique and standard methods fro...
The patterns of drug resistance and the frequency of conjugative R plasmids in intestinal Escherichia coli from 88 patients treated for a skin disease (acne vulgaris) with low oral doses of tetracycline are reported. The proportion of patients with resistant bacteria was progressively greater in patients who received tetracycline for 1 week, 4 weeks, or longer (from 50 to 88%). No multiply drug...
High antibiotic resistance frequencies have become a major public health issue. The decrease in new antibiotics' production, combined with increasing frequencies of multi-drug resistant (MDR) bacteria, cause substantial limitations in treatment options for some bacterial infections. To diminish overall resistance, and especially the occurrence of bacteria that are resistant to all antibiotics, ...
Plasmids that contain synthetic genes coding for small oligoribonucleotides called external guide sequences (EGSs) have been introduced into strains of Escherichia coli harboring antibiotic resistance genes. The EGSs direct RNase P to cleave the mRNAs transcribed from these genes thereby converting the phenotype of drug-resistant cells to drug sensitivity. Increasing the EGS-to-target mRNA rati...
BACKGROUND The growing burden of neonatal mortality associated with hospital-acquired neonatal sepsis in the developing world creates an urgent need for cost-effective infection-control measures in resource-limited settings. METHODS Using a before-and-after comparison design, we measured how rates of staff hand-hygiene compliance, colonization with drug-resistant pathogens (defined as ceftazi...
conclusions ethanol extracts of p. granatum (pericarp, leaves, flowers, seeds) have antibacterial effects against p. haemolytica which has shown resistance to all studied antibiotics. background continuous researches on drugs that solve the problem of growing number of resistant bacteria are important. objectives this research aims to investigate the effectiveness of anti-bacterial properties s...
The alarming increase of pathogenic bacteria that are resistant to multiple antibiotics is now recognized as a major health issue fuelling demand for new drugs. Bacterial resistance is often caused by molecular changes at the bacterial surface, which alter the nature of specific drug-target interactions. Here, we identify a novel mechanism by which drug-target interactions in resistant bacteria...
