Early and fast PCR detection of yeast bloodstream infections in immunocompromised patients particularly, antifungal susceptibility testing, molecular typing (RAPD, PFGE) and correlation of typing results with characteristics significant therapy.
Rychlá a včasná PCR detekce zejména hemotogenně diseminovaných kandidóz u imunodeficitních pacientů, testování citlivosti k antimykotikům, molekulárně-genetická typizace (RAPD a PFGE) a korelace výsledků typizace s klinickými a epidemiologickými údaji.
Opportunistic pathogens of the genus Candida produce secreted aspartic proteinases (Saps) that are considered as one of the virulence factors. While Saps of C. albicans and C. tropicalis have been studied extensively, information concerning proteinases secreted by other pathogenic Candida species is scarce. To our knowledge, enzymologic characterizations of Sap of C. parapsilosis (Sapp1p) and C. lusitaniae (Saplp) are limited. We have purified Saps of C. parapsilosis and C. lusitaniae from yeast culture supernatants and detected only one gene product of both Sapp1p and Saplp using isoelectric focusing and N-terminal sequencing. Molecular weight of Saplp determined by SDS-PAGE is approximately 42 000. For the highest enzyme activity, both Sapp1p and Saplp require pH ranging from 3 to 4 and temperature between 27-40 °C for Saplp and 45 °C for Sapp1p, respectively. At physiological temperature, both the proteinases are stable. The characterization of Saps of clinical isolates of C. parapsilosis and C. lusitaniae should contribute to design of novel drugs specifically targeted on proteinases.
