GIL, Marielsa et al. Capability of biofilm formation in Candida genus species of clinical origin. Revista médica Risaralda [online]. 2017, vol.23, n.2, pp.4-9. ISSN 0122-0667.

The aim of this research was to evaluate the capability of biofilm formation in Candida genus species from clinical samples with infectious conditions. The sample consisted of 70 isolates obtained from private clinical laboratories. Germ tube test and agar cornmeal with tween 80 microculture technique were used as species identification, meanwhile, quantification of biofilm formation capacity was performed by the polystyrene microplate technique. Among the results obtained in the research, isolated species were: Candida glabrata (34%), Candida albicans Complex (30%), Candidaparapsilosis Complex (27%) and Candida tropicalis (9%), of which 41 isolates (59%) formed biofilms, resulting Candida albicans and Candida glabrata Complex species with the highest degree of biofilms with 29% each, followed by Candida parapsilosis Complex with 27% and Candida tropicalis with 15%. Strains with more biofilm formation came from urine, followed by ear discharge, vaginal secretion and blood. However, by applying the Chi squaretest the Pearson, it was determined that there was no statistically significant association between thecapability of biofilm formation and the formation degree with clinical origin, neither there is association between the ability of biofilm formation and the formation degree with the species involved (p> 0.05).
