Phenotypic tolerance: antibiotic enrichment of noninherited resistance in bacterial populations.

abstract：:Candida parapsilosis has emerged as a common cause of invasive fungal infection, especially in Latin America and in the neonatal setting. C. parapsilosis is part of a closely related group of organisms that includes the species Candida orthopsilosis and Candida metapsilosis. All three species show elevated MICs for th...
