Abstract:
The presence of Granulicatella spp. in bacteremic episodes of neutropenic patients was recently highlighted whereas Abiotrophia defectiva, was only isolated in cases of infectious endocarditis. The aim of this study is to describe a case of A.defectiva bacteremia in a leukemic and febrile (40 degrees C) neutropenic (200 GB/mm3) boy. A.defectiva was only isolated from one of the two processed blood samples. Although the patient was undergoing an episode of varicela which could have accounted as the possible cause of fever, A. defectiva was considered a significant finding because this species is not part of the commensal skin flora. This case suggests that both A. defectiva and Granulicatella spp. should be regarded as possible causes of bacteremia in immunocompromised patients.
