Researchers in Iran studied 136 hospital patients to identify different types of Candida fungal infections using a molecular laboratory technique called PCR-RFLP. They found that while Candida albicans remained the most common species, other Candida species were increasingly prevalent in hospitalized patients. The study developed a cost-effective diagnostic method that could help developing countries identify these fungal infections faster and more accurately, though the dangerous multidrug-resistant Candida auris was not found in their samples.
