A rare pathogen causing invasive infection in a child on chemotherapy

Kocuria kristinae is a rare microbe causing infection in children. The genus Kocuria was previously classified in the Micrococcaceae family. It has been regrouped as Kocuria recently according to chemotaxonomic and phylogenetic studies.[1] Five out of 17 species of Kocuria were reportedly causing disease in humans, and K. kristinae is one of them.[2] It is an aerobe, which is catalase(+), coagulase(‑), gram‑positive coccus. It is a part of the human skin and oral flora and can cause bloodstream infections in immunocompromised and in patients with indwelling catheters.[3] The documented reports on Kocuria kristinae infection were very few and it is rarely reported in pediatric age group. We, here, summarize a case of Kocuria kristinae sepsis as a sign of possibility of disease from an uncommon organism and to steer up the proper antibiotic selection based on the Review of the literature ['Table 1].
