B. cepacia

One day on rounds the resident was presenting events overnight on a young patient who was previously healthy and was here for severe sepsis from cellulitis. After about a week on the vent, a sputum grew B. cepacia. I thought that was odd in a patient with no lung disease. A high res was even ordered and there was no bronchiectasis. Could never figure it out. As the weeks went by a few more cases here and there popped up. Infection-control was called in to investigate and they could not identify a source. We have very very few patients with cystic fibrosis in our hospital anyway.
Finally, with the help of an FDA new release, the culprit was identified and the product is now recalled.
