Studying the influence of surface topography on bacterial adhesion using spatially organized microtopographic surface patterns.

The influence of surface topography on bacterial adhesion has been investigated using a range of spatially organized microtopographic surface patterns generated on polydimethylsiloxane (PDMS) and three unrelated bacterial strains. The results presented indicate that bacterial cells actively choose their position to settle, differentiating upper and lower areas in all the surface patterns evaluated. Such selective adhesion depends on the cells' size and shape relative to the dimensions of the surface topographical features and surface hydrophobicity/hydrophilicity.

Candida orthopsilosis fungemias in a Spanish tertiary care hospital: incidence, epidemiology and antifungal susceptibility.

Background: Few studies exist on prevalence of fungemia by Candida orthopsilosis, with variable results.

Aims: To study the incidence, epidemiology and antifungal susceptibility of C. orthopsilosis strains isolated from fungemias over two years at a tertiary hospital.

[Cell surface hydrophobicity as an indicator of other virulence factors in Candida albicans].

Objective: To evaluate virulence factors involved in the adhesion process, such as cell surface hydrophobicity (CSH), adherence to plastic capacity, adherence capacity to buccal epithelial cells (BEC), and biofilm formation, in 17 strains of C. albicans isolated from bronchial aspirates of critically ill patients.

Method: The CSH of the strains of C.

Cellular surface hydrophobicity as an additional phenotypic criterion applied to differentiate strains of Candida albicans and Candida dubliniensis.

We have evaluated the cellular surface hydrophobicity (CSH) determination as an additional criterion to differentiate Candida albicans from Candida dubliniensis. Our results show that C. albicans when grown at 37 degrees C in Sabouraud is always hydrophilic, and C.
