Using light scattering technology to identify bacteria has been around for a few years (as evidenced by this paper from 2009 and this article from 2006. The methodology described in these articles use actual bacterial colony growth on conventional media for identification. This only shaves a day off turnaround time. This is handy, but can we do any better?
Enter Alifax SPA. They claim to have an automated analyzer capable detecting the presence of pathogenic bacteria, quantifying (in CFU/ml) that bacteria, and measuring the drug resistance of that organism in a few hours by using light scattering technology. Those techs that have worked in hematology or urinalysis are no stranger to this type of analyzer, but how well does it translate to the world of microbiology?
