New study 'pardons' the misunderstood egg

Genes involved in antibiotic resistance vary within a species

The recent emergence of multidrug resistance (MDR) in Acinetobacter baumannii, a bacteria that causes infections primarily among seriously ill patients in the intensive care unit who may have reduced immune systems, has raised concern in health care settings worldwide. When comparing the genome sequence of three MDR A. baumannii isolates and three drug-susceptible A. baumannii isolates, Case Western Reserve University School of Medicine found that one variation of bacteria would respond to antibiotics while another variation of the same bacteria may not. more
