Sea cu- cumber Holothuria atra is commonly known as the lollyfish. The antifimgal activity was detected using agar well diffusion method against the various fungal strains such as Trichoderma viride, Aspergillus niger, Aspergillus flavis, Candida albicans and Penicillium chrysogenum. Relatively high antifungal activity was seen against Candida albicans at 100 μL-1 concentration of extracts. Zone of inhibition was measured at 18 mm of diameter. The anti-tumor activities were detected against the Vero and Hep2 cell lines using MTT assay. The cells were treated with H. atra extract at concentrations 0.078-10mg mL-1. The extract showed high proliferative activity against the Hep2 cells. The body wall extracts of sea cucumber （H. atra） showed effective antifungal and antitumor activities All these findings suggest that the extracts could be used for the development of drugs.展开更多

In the bibliography, the most observable genre is Candida and less frequently found are other opportunistic such as Aspergillus, Rhizopus, Cryptococcus, and others. The authors determined the presence of fungi in the oral cavity of IC students, and their relationship with the concentration of secretory IgA in saliva. To this end, we collected 50 samples of oral cavity swabs, which underwent direct examination and culture in Sabouraud dextrose agar with chloramphenicol. For its identification, CHROMagar Candida and API Candida （BioMerieux） were used. We obtained nine positive cultures （7 Candida albicans and 2 Saccharomyses cerevisiae）, which represented 18% of the studied population. Throughout radial immunodiffusion （RID plates-PLATE）, we determined the concentration of secretory IgA. No relationship was observed between the colonized group and group that was not colinized. The colonization rate found is below the one described in the bibliography （30% to 50%）. However, these opportunistic fungi cause transitory colonization with no clinical relevance in IC patients and, its percentage can vary according to the studied population.展开更多
