An alternative respiratory pathway on Candida krusei : implications on suscepti...
Oliveira, Sofia Costa de; Marques, Belém Sampaio; Barbosa, Matilde; Ricardo, Elisabete; Vaz, Cidália Pina; Ludovico, Paula; Rodrigues, Acácio G.Our aim was to detect the presence of an alternative oxidase (AOX) in Candida krusei clinical strains and its influence on fluconazole susceptibility and in reactive oxygen species (ROS) production. Candida krusei clinical isolates were tested to evaluate the presence of AOX. Debaromyces hansenii 2968 (AOX positive) and Saccharomyces cerevisiae BY4742 (AOX negative) were used as control strains. Measurements of...
Virulence attenuation of Candida albicans genetic variants isolated from a pati...
Sampaio, Paula; Santos, Marlene; Correia, Alexandra; Amaral, Fábio E.; Chávez Galarza, Júlio César; Oliveira, Sofia Costa de; Castro, António G.The incidence of Candida albicans infections and the relapse episodes after antifungal treatment have increased in recent decades. Recurrences are mainly due to the persistence of the original infecting strain that may present genetic and genomic rearrangements during interaction with the host, reflecting strain adaptation. In this study, four isolates recovered from a patient during recurrent candidemia episod...
