Hi. My brother has been dealing with this infection for a long time has pockets and tunnels under his skin on his buttocks has had to have surgery several times to clean these pockets. Has been on antibiotics for a few weeks at a time but once completed these pockets and tunnels come back Dr said they were finally able to get a culture from a surgical biopsy site and Dx him with klebsiella pneunonial. Said his body has to much if this bacteria snd so it comes out his skin. If this is true why does he have an overabundance of this bacteria can it be treated? He is healthy otherwise.
