can anyone comment on this genetic bacteria tests???

has anyone had this?

> unexpected bacteria strains in the lung fluid of Denver children

> suffering from cystic fibrosis, findings that may lead to more

> effective therapies.

>

> Instead of standard culturing techniques, researchers used nucleic

> acid gene sequencing to rapidly detect, identify and classify

> pathogens found in the lungs of cystic fibrosis sufferers, said

> CU-Boulder Professor Norman Pace, who pioneered the method in the

> 1990s using microbes from Pacific Ocean hydrothermal vents. Pace and

> his colleagues at CU-Denver's Health Sciences Center and Denver's

> Children's Hospital identified more than 60 species of bacteria in

> samples of 28 cystic fibrosis patients in Denver. Thirteen samples

> contained bacteria that are not routinely assessed by culturing.

>

> The presence of the unexpected bacteria may help explain cases of

> unidentified lung inflammation and the consequent failure of

patients

> -- primarily children -- to respond to standard treatments, said

Pace.

> " The results show molecular sequencing is a more effective, faster

and

> far less expensive way to assess airway bacteria than routine

clinical

> cultures and better identifies targets for further clinical

> evaluation, " said Pace.

> Cystic fibrosis, a life-threatening genetic disease affecting about

> 30,000 people in the United States, is marked by a build-up of mucus

> in the lungs and pancreas that can clog organs, according to the

> Cystic Fibrosis Foundation. In addition to causing difficulty

> breathing, the thick mucus acts as a breeding ground for bacteria in

> the lungs that causes swelling, inflammation and infections that can

> lead to lung damage. Most deaths from cystic fibrosis are caused by

> such infections, said Pace.

> About 80 percent of pathogens identified in cystic fibrosis patients

> bacterial groups, including the group that causes strep infections,

bacterial

tests.
