2003 OCT 2 - (NewsRx.com & NewsRx.net) -- Candida albicans expresses different enzyme genes at different rates depending on location of infection and level of disease activity.
"The in vivo expression of Candida albicans secreted aspartyl proteinase (SAP1-SAP8) and phospholipase B (PLB1 and PLB2) genes was analyzed in 137 human subjects with oral and vaginal candidiasis or carriage. Total RNA was isolated from whole, unstimulated saliva or vaginal swabs, and the expression of SAP1-8 and PLB1-2 was evaluated by RT-PCR using specific primer sets," scientists in England report.
"A spectrum of SAP gene expression profiles was obtained from different C. albicans strains during symptomatic disease and asymptomatic carriage. SAP2 and SAP5 were the most common genes expressed during both infection and carriage. SAP1, SAP3, SAP4, SAP7, SAP8, and PLB1 expression was correlated with oral disease, whereas SAP1, SAP3, and SAP6-SAP8 expression was correlated with vaginal disease. Furthermore, SAP1, SAP3, and SAP8 were preferentially expressed in vaginal, rather than oral, infections," wrote J.R. Naglik and coauthors.
