Rising healthcare complications due to fungal infections increase the importance of efficient specimen collection and maintenance systems for correct identification and diagnosis. The CLSI M40-A2 protocol provides guidelines for laboratories assessing quality of medical transport devices, including swab transport systems (STS). This study assessed the efficiency of the Sigma Transwab® foam and flock swab in recovering and maintaining viability of different Candida spp. including C. auris, in different test conditions. Both swab types recovered and maintained viability of all Candida spp. with greater CFU at room temperature after incubation (24 and 48h) in comparison with swabs maintained at 4°C.
