- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This is a report of what happened to one patient, not a study that proves a treatment.
The short version
A germ never before seen in brain fluid caused an infection in one child, and one antibiotic cleared it.
What was studied. This is a report about one patient. He was a 13-year-old boy who had surgery and treatment before for a brain tumor called medulloblastoma, and the tumor came back.
What they found. The tumor blocked the flow of fluid in his brain. Doctors drained the fluid and removed the tumor. Three days after surgery he had a fever and signs of meningitis, which is an infection of the lining around the brain. A test of his spinal fluid grew a germ called Pandoraea pnomenusa. The germ was not killed by the antibiotics meropenem or ciprofloxacin. It was killed by cotrimoxazole, and that drug cleared his infection.
What this means, and what it doesn't
What it could mean: This tells doctors that this germ can infect the brain and spinal fluid, which had not been reported before. If a child gets this infection after brain surgery, some common antibiotics may not work. Knowing which drug worked here may help a care team choose treatment faster.
What it doesn't mean: This is a report about one child, not a study of many people. It does not test a new brain tumor treatment, and it does not change tumor care. It says nothing about how well anyone else will do, and it is not a cure for medulloblastoma or for this infection in general.
