The persistence of multifocal colonisation by a single ABC genotype of Candida albicans may predict the transition from commensalism to infection.

Candida albicans is a common member of the human microbiota and may cause invasive disease in susceptible populations. Several risk factors have been proposed for candidaemia acquisition. Previous Candida multifocal colonisation among hospitalised patients may be crucial for the successful establishment of candidaemia.
