August 2017—Due to an ever-changing workforce, many new and inexperienced technologists are working in the microbiology lab and appear to be having difficulty interpreting cultures and troubleshooting when an organism in question may not be significant. As an example, a scant growth of Micrococcus was isolated and reported from a cerebrospinal fluid culture; it was not seen in the Gram stain and was negative for leukocytes. Contaminants had been noted on some of the media plates at this time as well, but many of these inexperienced technologists do not have the confidence to ignore obvious contaminants or suggest the possibility of contamination. Is there some guidance or troubleshooting tools for these situations?
