Association of virulence factors with antifungal resistance and clinical outcomes in Candida species isolated from bloodstream infections.

Non-albicans Candida species, especially C. parapsilosis and C. tropicalis, exhibit higher virulence factors and antifungal resistance, correlating with increased mortality in bloodstream infections.

• Why it matters: Candidemia causes significant morbidity and mortality, and understanding virulence and resistance profiles is crucial for effective treatment, yet data on their relationship remains limited.
• What they did: The study analyzed 100 Candida isolates from blood cultures, assessing virulence factors such as hemolysin, phospholipase, proteinase activities, and biofilm formation, alongside antifungal susceptibility testing.
• The result: Strong virulence factors and biofilm formation were linked to higher antifungal resistance and mortality, emphasizing the need for species identification and susceptibility testing to improve clinical outcomes.
