As a result, almost three more years were required to figure out how the different parts of the kinase confer resistance to different
macrolide antibiotics.
The researchers found that the kinase enzymes have an impressive ability to confer resistance to many different
macrolide antibiotics — the two enzymes that were studied in detail are essentially able to confer resistance to all
macrolide antibiotics currently in use.
In one instance, the investigators discovered a novel gene conferring resistance to
the macrolide antibiotics, which was a small 61 residue proline - rich peptide, said Topp.
Particularly the microbiota of the children who had received
macrolide antibiotics, such as azithromycin or clarithromycin, within the past two years differed from normal.
