[Histonet] Re: False positive AFB
The acid-fast bacilli that come out of the water faucet are supposedly Mycobacterium gordoneae (gor-DOH-nee-ee, after microbiologist Mary Gordon) - a synonym is Myco. aquae (ACK-wee). They aren't pathogenic (well, maybe in situations of extremely compromised immune function).
They stain with both light-microscopic and fluorescent techniques. The trick to recognizing them is that usually they're slightly out of the plane of the section, and in tissue sections they turn up at random rather than in places in tissues where a pathologist will expect to see them.
