RESUMO
Introduction: Kocuria kristinae is a commensal organism, sometimes considered as a lab contaminant, but its repeated isolation from clinical samples in immunocompromised patients should raise red flags. Materials and Methods: We confirmed the infection with re-isolation of the organism from the same site before starting treatment. For the identification of Kocuria kristinae we used IDGP cards on VITEK 2 compact system. Antibiotic susceptibility test was done manually following CLSI guidelines 2018 for Coagulase-negative staphylococci. Results: A total of 510 major head neck oncosurgeries were performed during the period of two years. Out of which 120 patients had skin and soft tissue infections. Out of these infected patients, 90 were culture positive and of these Kocuria kristinae were isolated in 12 patients. Resistance to penicillin and oxacillin is seen in all isolates. Conclusion: Kocuria kristinae should not be ignored as a commensal flora or lab contaminant in immunocompromised hosts. Its Increase in resistance pattern is a matter of concern. It is an ignored opportunistic pathogen whose detailed sensitivity test should be developed to treat patients timely and effectively.
RESUMO
We read with interest the case report "Endocarditis bacteriana por Kocuria kristinae en un paciente inmunocompetente. Reporte de caso" by S.M. Rojas Molina, et al. The authors described about the Kocuria kristinae endocarditis in an immunocompetent woman. We agree that Kocuria kristinae is a rare organism and endocarditis caused by this organism is worth mentioning. However, there are certain questionable points in the report which we would wish to highlight and which need clarification.
Hemos leído con interés el informe de caso "Endocarditis bacteriana por Kocuria kristinae en un paciente inmunocompetente. Reporte de caso" de S.M. Rojas Molina, et al. Los autores describen la endocarditis por Kocuria kristinae en una paciente inmunocompetente. Estamos de acuerdo en que Kocuria kristinae es es un organismo raro y la endocarditis causada por este organismo es digna de mención. Sin embargo, hay ciertos puntos cuestionables puntos dudosos en el informe que nos gustaría destacar y que necesitan ser aclarados.

Los miembros del género Kocuria corresponden a cocos Gram positivos ubicuos, generalmente inocuos y que hacen parte de la flora saprófita de un porcentaje importante de la población; ocasionalmente han sido descritos como los agentes responsables de patologías infecciosas, principalmente dentro del contexto de pacientes que concomitantemente cursan con enfermedades crónicas y estados de inmunosupresión. Son escasos los casos reportados como causa de endocarditis en pacientes inmunocompetentes a nivel global por especies de este género. Se expone el caso de una mujer inmunocompetente de 44 años, sin antecedentes de importancia, en quien solo el diagnóstico microbiológico permitió confirmar la presencia de Kocuria kristinae como agente causal de su endocarditis infecciosa; la literatura señala la dificultad existente al momento de diferenciar la endocarditis producida por Staphylococcus spp. versus Kocuria kristinae por su evolución clínica similar, indicando la importancia de la microbiología al momento de identificar y diagnosticar apropiadamente.
Members of the genus Kocuria correspond to ubiquitous, generally harmless, Gram-positive cocci that are part of the saprophytic flora of a significant percentage of the population; occasionally they have been described as the agents responsible for infectious pathologies, mainly in the context of patients who concomitantly have chronic diseases and are under an immunosuppression state. There are few cases reported as a cause of endocarditis in immunocompetent patients globally by species of this genus. We present the case of a 44-year-old immunocompetent woman, with no relevant history, in whom only the microbiological diagnosis confirmed the presence of Kocuria kristinae as the causative agent of her infectious endocarditis; Literature points out the difficulty existing when differentiating endocarditis produced by Staphylococcus spp. versus Kocuria kristinae because of their similar clinical evolution, indicating the importance of microbiology when identifying and diagnosing accurately.

Kocuria kristinae, part of the normal flora of the skin and oral mucosa, is seldom reported as a human pathogen; infection is mostly associated with immunocompromised patients in healthcare facilities. Here, we describe the first case of bacteremic empyema caused by K. kristinae acquired from the community. K. kristinae was isolated from pleural effusion and two sets of peripheral blood samples drawn from two different sites. The empyema resolved after the insertion of a chest tube and intravenous administration of piperacillin-tazobactam and levofloxacin.
