A growing number of American children are developing infections caused by a worrisome type of antibiotic-resistant bacteria, a new study reports. While still rare, the bacteria are being found more often in children of all ages, especially those who are 1 to 5 years old, the study found. Investigators analyzed samples collected from children nationwide between 1999 and 2011 to assess the prevalence of the antibiotic-resistant type of bacteria called Enterobacteriaceae, which produces an enzyme called extended-spectrum beta lactamase (ESBL). The enzyme defeats many strong antibiotics, the study authors said.
