U.S. pediatricians have discovered a strain of bacteria that causes ear infections and is resistant to all drugs approved for the condition, a medical report said Wednesday.
The two pediatricians uncovered the strain when performing tympanocentesis, or an ear tap, on children after several antibiotics failed to clear up their ear infections. The procedure involves puncturing the eardrum and draining fluid to relieve pain.
The bacteria were found in the drained fluid and tested by researchers at the University of Rochester Medical Center. They were found to be a strain of superbug called 19A.
The findings were published Wednesday in the Journal of the American Medical Association.
In tests on children, nine cases of 19A were identified between 2003 and 2006, according to the study. Four children had been unsuccessfully treated with two or more antibiotics.
The only treatment for adults is levofloxacin, a powerful antibiotic not recommended for children. Since there were no other options, the children with the antibiotic-resistant strain were treated with the levofloxacin and the treatment worked.
The authors theorize the 19A strain was most likely created by a combination of the speed of bacterial evolution and the overprescribing of antibiotics.
They warn that physicians should be aware of the risk of the bacteria spreading to other parts of the body, such as the lungs or bloodstream, resulting in cases of pneumonia or meningitis that can only be treated with unconventional antibiotics.
