Hyphal Formation is Enhanced by 121°C Heat Inactivation of Serum Added to Culture Media

Background: A novel method for inducing hyphae formation, was described.Methods:Mycelia of experimental and clinical strains from 100 patients with oral lichen planuswere cultured in RPMI 1640 medium with 56°C or 121°C inactivated calf sera. After these strains were cultured for 2 h to 7 days, the average hyphae formation rate was observed under light microscopy. Results: The 121°C inactivated calf serum showed better outcomes than 56°C inactivated calf serum in terms of time and amounts of hyphae products. Conclusions:For Candida albicanshyphae culture, the 121°C inactivated serum is superior to the 56°C inactivated serum
