Escherichia coli is a major cause of extraintestinal infections in all age group. However, the infection becomes more severe when patients have some underlying condition such as Diabetes Mellitus. The aim of the study was to determine whether diabetic mellitus may act as an important risk factor for the E. coli to express drug resistance property. This descriptive study was carried out in a multi-specialty tertiary care hospital. One hundred and twenty-seven E. coli isolates from diabetic patients, and one hundred seventy-three isolates from nondiabetic patients were studied...

Evolution has provided environmental bacteria with a plethora of genes that give resistance to antibiotic compounds. Under anthropogenic selection pressures, some of these genes are believed to be recruited over time into pathogens by horizontal gene transfer. River sediment polluted with fluoroquinolones and other drugs discharged from bulk drug production in India constitute an environment with unprecedented, long-term antibiotic selection pressures. It is therefore plausible that previously unknown resistance genes have evolved and/or are promoted here...

Mycobacterium abscessus has emerged as an important pathogen in people with chronic inflammatory lung diseases such as cystic fibrosis, and recent reports suggest that it may be transmissible by fomites. M. abscessus exhibits two major colony morphology variants: a smooth morphotype (MaSm ) and a rough morphotype (MaRg ). Biofilm formation, prolonged intracellular survival, and colony variant diversity can each contribute to the persistence of M. abscessus and other bacterial pathogens in chronic pulmonary diseases...

Amikacin, kanamycin and capreomycin are listed among the most important 2nd line drugs for multidrug resistant tuberculosis. Although amikacin and kanamycin are administered in the same dose and show the same pharmacokinetics, they have different WHO breakpoints suggesting that the two drugs have a different minimal inhibitory concentrations (MIC). The aim of this paper was to investigate possible differences in MIC between the aminoglycosides and capreomycin.Using the direct concentration method, a concentration range of amikacin, kanamycin and capreomycin (0...

PURPOSE: Meropenem/vaborbactam is a novel intravenous antibiotic combining the carbapenem, meropenem, with a novel β-lactamase inhibitor, vaborbactam. Meropenem/vaborbactam is administered as a 3-hour infusion given every 8 hours, thereby potentially restricting an intravenous line for 9 h/d. Intravenous medications may be given concurrently via Y-site when compatibility data are available. Herein, physical compatibility was determined for the identification which medications can be coadministered with meropenem/vaborbactam via Y-site...

Urinary tract infections are the most frequent documented bacterial infections in children. The antibiotic choices proposed in this manuscript are based on the guidelines published by the Pediatric Infectious Disease Group (GPIP) and the French-Language Infectious Disease Society (SPILF). Dipstick positive for leukocytes and/or nitrites must precede in most circumstances (excluding the newborns, neutropenic patients and those with sepsis), urine culture and antibiotic prescription. The proportion of extended-spectrum β-lactamase (ESBL) Escherichia coli strains has increased steadily in recent years, and the situations in which oral antibiotic switch is frequently not available are increasing...
