     in the past two decades, candida species have become the second leading cause of invasive mycosis in immunocompromised patients. in order to colonize their hosts, these microorganisms express adhesins and cell wall proteins that allow them to adhere and neutralize the reactive oxygen species produced by phagocytic cells during the respiratory burst. however, the precise mechanism by which candida cell wall proteins change their expression in response to oxidative stress has not been described. in an attempt to understand this change in response to oxidative stress, in this study, three candida species, namely, c. albicans, c. glabrata and c. krusei, were exposed to increasing concentrations of h2o2 and induced cell wall proteins were identified by two-dimensional gel electrophoresis and peptide mass fingerprinting. sequence analysis of differential proteins led to the identification of two heat-shock proteins in c. albicans, two enolases in c. glabrata and one enolase in c. krusei. enolases may be involved in the protection of pathogenic cells against oxidative stress as suggested by the decrease in their expression when they were exposed to high concentrations of h2o2. to our knowledge, this is the first demonstration that expression of these proteins changes in response to oxidative stress in different candida species. this knowledge can eventually facilitate both an early diagnosis and a more efficient treatment of this mycosis.
