Isolates shared a background that took shape in 2006, when MCR-1 was first mobilized.
A significant increase in cases of severe sepsis and septic shock within 90 days of hospital discharge was observed among patients exposed to antibiotics during their previous hospital stay, researchers with the Centers for Disease Control and Prevention reported today in Clinical Infectious Diseases.
Three studies presented at IDWeek 2017 in San Diego last week focused on the emerging colistin-resistance gene MCR-1 in the United States.
Transmission chain mapping points to prolonged colistin use in livestock and poultry.
Dutch investigators have identified the colistin resistance gene MCR-1 in nearly 25% of samples of Dutch retail chicken meat, according to a new study in Antimicrobial Resistance and Infection Control.
For the study, the investigators bought 214 chicken meat samples from four supermarket chains throughout the Netherlands in 2015. They collected 53 or 54 samples from each chain.
Scientists report the first detection of MCR-4, as well as MCR-3 in Denmark and Italy.
An experimental drug that belongs to a new class of antibiotics showed promise in lab tests against multidrug-resistant (MDR) gram-negative bacteria, and was protective against the bacterium that causes plague in mice, according to a study yesterday in mBio.
A hands-on educational program dramatically increased primary school students' knowledge of antibiotic action and use, according to a study yesterday in the International Journal of Antimicrobial Agents.
The authors of the study say they're concerned the gene may already be widely disseminated.
A review and meta-analysis of studies on bacterial transmission and antibiotic resistance during the annual pilgrimage to Mecca has found rising rates of resistance among certain gram-positive and gram-negative bacteria, researchers report in Travel Medicine and Infectious Disease.
