Federal health officials say a network they set up last year to identify deadly "nightmare bacteria" is helping control these germs, according to an article on the NPR website.
But they also admit the system would be more effective if more hospitals and doctors participated.
The Centers for Disease Control and Prevention (CDC) identified more than 1,400 people who tested positive for these kinds of germs last year.
In January 2017, the CDC established a nationwide network of labs to make it easier to identify the killer bacteria. The CDC says that the first nine months of that effort were successful.
