RESUMO
Kocuria roseabelongs to genus Kocuria(Micrococcaceaefamily, suborder Micrococcineae, order Actinomycetales) that includes about 11 species of bacteria. Usually, Kocuria spare commensal organisms that colonize oropharynx, skin and mucous membrane; Kocuria spinfections have been described in the last decade commonly affecting immunocompromised patients, using intravenous catheter or peritoneal dialysis. These patients had mainly bacteremia/recurrent sepsis. We hereby describe the case of a 10-year-old girl, immunocompetent, who had endocarditis/sepsis by K. roseawhich was identified in five different blood cultures by Vitek2 ID-GPC card (BioMérieux, France). Negative HIV serology, blood count within normal range of leukocytes/neutrophils and lymphocytes, normal fractions of the complement, normal level of immunoglobulins for the age; lymphocyte immunophenotyping was also within the expected values. Thymus image was normal at chest MRI. No catheters were required. Identification of K. roseawas essential to this case, allowing the differentiation of coagulase-negative staphylococci and use of an effective antibiotic treatment. Careful labo- ratory analysis of Gram-positive blood-born infections may reveal more cases of Kocuria spinfections in immunocompetent patients, which may collaborate for a better understanding, prevention and early treatment of these infections in pediatrics.
