Abstract: | A new medium consisting of UHT milk, tween 80 and agar is described for the development of both germ tube and chlamydoconidia byCandida albicans. In total 172 isolates from clinical specimens, includingC. albicans (112),C. guilliermondii (4),C. krusei (3),C. parasilopsis (16).C. tropicalis (28),Torulopsis glabrata (6) andTrichosporon beigellii (3), were examined in this medium by using the standard method. A higher percentage (98.2%) of germ tube production byC. albicans was found in this medium than in undiluted serum (90.2%). In addition, onlyC. albicans was found to be able to produce a high percentage of chlamydoconidia (95.5%) after 48 hours' incubation. In comparison with the conventional medium, corn meal tween 80 agar (21.4%), this new medium gives a significantly higher percentage and abundance of chlamydoconidia production. Being simple, cheap and easy to prepare, the new milk medium is proposed as very practical in the clinical mycology laboratory. |
