Low sensitivity of conventional fungal agars in fungemia by Rhodotorula mucilaginosa: description of two cases.

ABSTRACT:

Background

Although most bloodstream yeast infections are caused by Candida spp., infections by rare or less common species have increased in recent years. Diagnosis of infections caused by these species is difficult due to the lack of specific symptoms and adequate diagnostic tools.

Cases presentation

We describe two cases of fungemia by Rhodotorula mucilaginosa within a few months of each other, in a secondary Spanish hospital. In both cases, diagnosis was challenging. Blood subcultures in conventional fungal media were persistently negatives and the use of non-conventional fungal media was essential for isolating the yeasts and achieving a correct diagnosis. 1-3 beta-D-glucan detection and a panfungal PCR assay were helpful techniques to confirm the diagnosis CONCLUSION:
