Scientists in Barcelona said Candida orthopsilosis originated from two parent strains in a rare event called hybridization as a result of climate change.
'We have spent years trying to answer the question of what makes some species pathogenic for humans and others, such as those we have in our microbiome, not. 'Our results show that hybridization-a process that has received little attention so far- allows the rapid acquisition of properties that allow human infection. Therefore, in fungi, this process could be a shortcut to conquer a species like ours.'
The researchers said hybrids could become more common with rising temperatures and changes in ecosystem conditions, combined with globalization and human action, such as the extensive use of fungicides and antibiotics in agriculture.
