The echinocandin antifungal drugs inhibit synthesis of the major fungal cell wall polysaccharide β(1,3)-glucan. Echinocandins have good efficacy against Candida albicans but reduced activity against other Candida species, in particular Candida parapsilosis and Candida guilliermondii. Treatment of Candida albicans with a sub-MIC level of caspofungin has been reported to cause a compensatory incr...

As there are sparse data on the impact of growth media on the phenomenon of biofilm development for Candida we evaluated the efficacy of three culture media on growth, adhesion and biofilm formation of two pathogenic yeasts, Candida albicans and Candida tropicalis. The planktonic phase yeast growth, either as monocultures or mixed cultures, in sabouraud dextrose broth (SDB), yeast nitrogen base...

Rosner, Richard (St. Joseph's Hospital, Paterson, N.J.). Isolation of Candida protoplasts from a case of Candida endocarditis. J. Bacteriol. 91:1320-1326. 1966.-A case of endocarditis caused by Candida tropicalis is described. Even though the patient was receiving adequate therapy, and all routine blood cultures were negative for growth, the patient continued to give clinical evidence of active...

The purpose of this work was to evaluate biochemical and serological methods to characterize and identify Candida species from the oral cavity. The strains used were five Candida species previously identified: C. albicans, C. guilliermondii, C. parapsilosis, C. krusei, C. tropicalis, and Kluyveromyces marxianus, as a negative control. The analyses were conducted through the SDS-PAGE associated ...

Paradoxical growth was noted in RPMI 1640 and antibiotic medium 3 in the case of 14 and 1 of 15 Candida tropicalis strains, respectively, at a caspofungin concentration of 12.5 microg/ml using minimum fungicidal concentration tests. Time-kill assays showed that against isolates killed at lower concentrations, caspofungin at a concentration of 12.5 microg/ml was only fungistatic.

To clarify the pathogenicity and the pathogenic factors of Candida tropicalis strains, five strains, IFO 0199, IFO 0587, IFO 0589, IFO 1400, and IFO 1647, of C. tropicalis were tested for their lethality to mice, adherence to Hela cells, hydrophobicity, cell growth under acidic conditions (pH 2.0-5.9), and sucrose assimilation using C. albicans NIH A-207 strain as reference. The pathogenicity f...

Chromogenic Candida Agar is a novel differential culture medium that is claimed to facilitate isolation and identification of Candida albicans, Candida tropicalis and Candida krusei. The performance of this medium was evaluated for presumptive identification of 521 yeast strains, representing 23 different species, for detection of specimens containing yeast mixtures, and for direct isolation of...

Olive mill wastewater (OMW), which is generated during olive oil production, has detrimental effects on the environment due to its high organic load and phenolic compounds content. OMW difficult biodegrade, but represents a valuable resource of nutrients for microbial growth. In this study, yeast strains were screened their growth usually found in responsible antimicrobial effects. Candida trop...

Paradoxical growth (PG) has been described for echinocandins and is characterized by cell growth at drug concentrations above the MIC. In this study, two isolates each of Candida albicans, C. tropicalis, C. orthopsilosis, and C. parapsilosis, all of which displaying PG in response to caspofungin, were subjected to MIC, minimal fungicidal concentration (MFC), and time-kill curve assays to evalua...
