Cheap and rapid in-house method for direct identification of positive blood cultures by MALDI-TOF MS technology.

Background: Rapid and accurate pathogen identification in blood cultures is very important for septic patients and has major consequences on morbidity and mortality rates. In recent years, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS)-based technology has become useful for highly specific and sensitive identification of bacteria and yeasts from clinical samples including sterile body fluids. Additional in-house methods enabled direct identification from blood cultures following various preparation protocols.

Tinea capitis-like infection caused by Rhodotorula mucilaginosa in a shelter for African Refugee Children in Northern Israel.

Rhodotorula is a genus of unicellular pigmented yeasts, part of the division Basidiomycota. In this article, we report three cases of refugee children in a day care shelter in northern Israel who were clinically diagnosed and treated empirically as with ringworm infection but with clean and exclusive growth of Rhodotorula mucilaginosa in repeated cultures of several skin samples. Skin infections caused by this yeast are rare and there are few reports in the literature, mainly in patients who are immunocompromised.
