Abstract
We report a tale of two cases of neonates, where India Ink preparation of cerebrospinal fluid (CSF) received in glass vials was suggestive of Cryptococcus; however, the absence of correlation and report of cases sequentially from the same unit raised alarm bells. Repeat smears using routine in-house and newly prepared stains were prepared and repeat sampling was collected in a strictly sterile specimen container, which resulted in negative microscopy for repeat samples (uncentrifuged and centrifuged). The source of contamination was found to be non-sterile glass vials used for CSF collection. This report underlines the requisite to maintain an aseptic chain from sample collection to processing, to prevent reporting of pseudo-infections that can upset diagnostic accuracy, especially when the aseptic chain has not been maintained.
