The selection of antibiotic-resistant mutant bacteria is proposed to occur in a drug concentration range (the mutant selection window) that extends from the minimum inhibitory concentration (MIC) of susceptible cells to the MIC of the least susceptible, single-step bacterial mutants (the mutant prevention concentration [MPC]). MPCs were estimated for tobramycin, chloramphenicol, rifampicin, pen...
The occurrence of multiple drug resistant (MDR) Pseudomonas aeruginosa strains are increasing worldwide and limiting our therapeutic options. It is a major health concern due to increased antibiotic resistance (Strateva and Yordanov, 2009). More to the problem, MDR Pseudomonas aeruginosa often establishes itself in already compromised patients, such as those with cystic fibrosis or in hospitali...
Infections caused by antibiotic-resistant bacteria are a rising public health threat and make the identification of new antibiotics a priority. From a cell-based screen for bactericidal compounds against Mycobacterium tuberculosis under nutrient-deprivation conditions we identified auranofin, an orally bioavailable FDA-approved antirheumatic drug, as having potent bactericidal activities agains...
Skin wounds are continuously exposed to bacteria and can easily become infected. Infected wounds require antibiotic treatment, and infections caused by drug-resistant bacteria are an important public health problem. Antimicrobial peptides have broad-spectrum antibacterial activity, induce little or no drug resistance and may be suitable for treating skin infections caused by drug-resistant bact...
Mobile phones and stethoscopes used in neonatology units could be colonized by potentiel bacteria pathogens. It can be a vector of severe nosocomial infections and multi-drug-resistant pathogens. The aim of this study is to evaluate the microbial contamination of mobile phones and stethoscopes, used by medical and paramedical staff. The study was conducted in neonatal intensive care unit (NICU)...
Considering antimicrobial resistance problem, marine microorganisms with the bioactivity against multi-drug resistant (MDR) pathogens have attracted many scientific interests. To address this issue, a total of 21 marine actinomycetes isolated from the Caspian Sea have been screened out. Primary screening via cross-streak method revealed that 3 strains: MN2, MN39, and MN40 produce antimicrobial ...
Peritonitis is a debilitating infectious complication of peritoneal dialysis (PD). Drug-resistant bacterial peritonitis typically has a lower response rate to antibiotics. In the past 15 years, newer antibiotics with activities against drug-resistant Gram-positive bacteria have been developed. In most circumstances, peritonitis due to methicillin-resistant staphylococci responds to vancomycin. ...
Despite recent advances in drug delivery systems and tissue engineering, several challenges still need to be overcome for these new technologies reach patients. The number of cancer cases is increasing yearly, the future projection frightening. Another major health concern rise antibiotic-resistant bacteria. uncontrolled excessive use antibiotics has allowed bacteria undergo mutation processes,...
