Genetic material from foam samples is extracted and we identify the specific organisms responsible for Nocardia foam outbreaks. From testing, we have found most Nocardia foams are caused by a bloom of Gordonia species. We use Gordonia specific primers, qPCR gives quantitive data within a few hours of starting the test.
The qPCR advantage stems from its sensitivity and low per test cost. Unlike older microscopic or plate count techniques, qPCR can detect foaming microbes at much lower levels before they become a problem. You can adjust wasting and take corrective actions before the heavy, problem foaming.
