BACKGROUND Non-typhoidal Salmonella (NTS) cause the majority of bloodstream infections in Ghana, however the mode of transmission and source of invasive NTS in Africa are poorly understood. This study compares NTS from water sources and invasive bloodstream infections in rural Ghana. METHODS Blood from hospitalised, febrile children and samples from drinking water sources were analysed for Sa...
This study investigated the species prevalence and antibacterial resistance among enterococci isolated in Kuwait hospitals. They consisted of 415 isolates of Enterococcus faecalis (85.3 %), Enterococcus faecium (7.7 %), Enterococcus casseliflavus (4.0 %), Enterococcus avium (1.2 %), Enterococcus durans (1.0 %), Enterococcus gallinarium (0.5 %) and Enterococcus bovis (0.2 %) isolated from urine ...
Acquired or inherent drug resistance is the major problem in achieving successful cancer treatment. However, the mechanism(s) of pleiotropic drug resistance remains obscure. We have identified and characterized a cellular metabolic strategy that differentiates drug-resistant cells from drug-sensitive cells. This strategy may serve to protect drug-resistant cells from damage caused by chemothera...
Staphylococcus aureus and Staphylococcus epidermidis strains isolated at eight large medical centers in Korea were examined for methicillin resistance and resistance to eight other antibiotics; cefazolin, cefamandole, cefuroxime, cefoxitin, cefotaxime, moxalactam, penicillin G and vancomycin. Methicillin resistance was found in 296 of 1225 strains (24.2%) of S. aureus and 126 of 348 strains (36...
Abstract Antimicrobial resistance (AMR) is a global health threat, and antimicrobial use in animal production for growth enhancement or prophylaxis contributes to the development of AMR. A cross-sectional study was conducted investigate prevalence methicillin-resistant Staphylococcus aureus (MRSA) poultry farm attendants Kebbi, North-Western Nigeria. total 207 cloacal nasal swabs were randomly ...
The acquisition of blaNDM-1 gene by Gram negative bacteria has emerged as critical threat to human health as these organisms display high resistance to available antibiotics. The presence of this gene has been observed in both clinical as well as environmental settings. The present study was carried out to evaluate the prevalence of blaNDM-1 containing microorganisms in water sources. A total o...
We modeled estimates of the incidence, deaths, and direct medical costs of Staphylococcus aureus infections in hospitalized patients in the New York City metropolitan area in 1995 by using hospital discharge data collected by the New York State Department of Health and standard sources for the costs of health care. We also examined the relative impact of methicillin-resistant versus -sensitive ...
O’Toole is absolutely right that most antibiotic genes probably evolved in the environment long ago (1), but the letter ignores the principle of selection, which is an essential component of Darwinian evolution. Antibiotic use in agriculture has been shown repeatedly to contribute to antibiotic resistance among human pathogens and commensals. We do not expect that any microbiologist would argue...
Sixty multiprious Holstein cows were fed treatment diets from 11 to 40 d postpartum with corn silage as the forage. Treatment diets each contained a different supplemental protein: 1) solvent soybean meal; 2) extruded soy product; 3) combination of corn gluten meal and distillers dried grains with solubles; and 4) a combination of protein sources from diets 2 and 3. Covariate adjusted means for...
this laboratory study simultaneously was conducted to evaluate the resistance to heavy metals, silver, cadmium and a number of commonly used antibiotics. sampling was done in 2014 of the two silver workshops in isfahan, and the inlet of phase 2 of shahin shahr wastewater treatment plant, isfahan. to isolate resistant bacteria to metal silver and cadmium and review multiple resistance to other m...
