Representative photograph showing haemolysis promoted by the haemolytic factor produced by C. tropicalis . For haemolysis assays, cell-free culture supernatants and RBCs were mixed at a 1:1 (v/v) ratio following incubation at 37°C for 15 h. (+) positive control (total lyses of RBCs in the presence of SDS), (1–2) haemolysis promoted by isolate 344.07 following growth in the presence and absence of RBCs, respectively, and (−) negative control (RBCs cells suspension with RPMI plus PBS buffer).
