When kids catch pneumonia from Mycoplasma, doctors often reach for macrolide antibiotics like azithromycin. But in one hospital in Anhui, China, almost every case fought back. Researchers tested 71 children with confirmed Mycoplasma pneumonia and found that 67 of them—94%—had strains that resisted these drugs.
These resistant infections clearly took a heavier toll. Kids with resistant pneumonia had fever for about six and a half days, compared with four days for those with susceptible strains. Hospital stays were longer, too, and inflammatory markers were higher. Nearly 21% of resistant cases needed a different antibiotic because the first one didn’t work, while none of the susceptible cases did. Persistent cough and slower clearing on chest X-rays were also more common with resistant bugs.
This was a small look back at hospital records, with only four children whose infections were still susceptible to macrolides. That makes it hard to draw broad conclusions. Still, the pattern is stark: when the bacteria resist the usual medicine, kids are sicker for longer and more often need a change in treatment.
