Warning over hospital infection:
[Via BBC News | Health | World Edition]
Hospitals could face a growing threat from a potentially deadly bacterial infection, warn scientists.
Another antibiotic-resistant bug – Stenotrophomonas maltophilia. Not a big one yet. Britain had only 1000 cases of blood poisoning from this bug last year. But 1/3 were fatal. Not a good average.
Steno does not get passed as easily as Staph but it is a nasty bacteria found on the biofilms seen with respirators, catheters or other pieces of equipment. So it is of particular concern to hospitals.
Steno is an interesting organism. It can grow in media with very high levels of toxic heavy metals.
And, thanks to Open access, you can read the article that just came out describing the genome of this bacterium. Four million base pairs. It possesses a large number of biological pathways that can deal with antibiotics as well as heavy metals.
This antibiotic resistance is intrinsic and is not derived from outside sources, as is often the problem with other bacteria that cause problems in hospitals. Luckily, this bacteria is purely an opportunistic pathogen and is not easily spread. But, the final sentence of the genome paper does make it obvious that we need to keep our eyes on this pathogen.
“We are starting to build up a picture of an organism that is a true opportunist, which, while lacking many conventional key virulence determinants, has nevertheless emerged as a considerable threat.”
