 Cedosporium and Lamentospora species are two types of opportunistic fungi that can cause disease in humans. These fungi are known for their resistance to most antifungal drugs, which makes them difficult to treat. They also have the ability to form biofilms on various surfaces, including plastic, glass and metal. In this study, researchers found that both species formed biofilms on polystyrene plates containing different sugars, but they did not form biofilms on synthetic cystic fibrosis medium or yeast-nitrogen base. This suggests that sugar may be important for biofilm formation by these fungi. This article was authored by Thais Pereira de Mello, Marta Helena Brancinha, André-Louis César dos Santos and others.
