A customer in (b)(6) reported gram staining issues for blood culture samples from two patients (p1, p2), in association with the previ? Color gram instrument. The customer stated that blood culture bottles for each patient, were processed with the bact/alert? Instrument and flagged as positive. The cultures were then placed on isolation media and also gram stained. The initial gram stain results were gram negative coccobacilli (p1) and bacilli (p2). After 24 hours there was no growth on the isolation media, so the same bottles had the gram stain repeated, and the results were gram positive coccobacilli (p1) and bacilli (p2). Vitek? Ms identified both samples as listeria monocytogenes (gram positive bacilli). The customer reported that when coloring these blood culture samples in the instrument, they were accompanied by other samples in which bacterial morphology was observed adequate for each type of sample and where both gram-positive and gram-negative bacteria are detected. The customer stated the wrong result was reported to the physician but patient treatment was not impacted. The patient's clinical signs did not coincide with the symptoms of a gram-negative microorganism, so the doctor decided to continue with the initial treatment until the final result of the culture. P1 was a (b)(6) female renal patient, and p2 was a newborn patient. There is no indication or report from the hospital or treating physician to biom? Rieux that the discrepant result led to any adverse event related to the patient's state of health. A biom? Rieux internal investigation will be initiated.
