RESUMO
The increase of infections due to non-Candida albicans species made it very necessary to conduct adequate characterization to be able to identify the species of Candida isolated from traditional fermented foods. In this study, based on their hue on Candida Chromogenic Agar medium, a total of 136 yeast strains were isolated from tchapalo and bangui. Molecular identification based on PCR-RFLP of internal transcribed spacers of rDNA (ITS) and sequencing of the ITS and the D1/D2 regions allowed us to assign these isolates to seven species: Candida tropicalis, Candida inconspicua, Candida rugosa, Saccharomyces cerevisiae, Kluyveromyces marxianus, Hanseniaspora guilliermondii, Trichosporon asahii. With the respect to each beverage, six species were found among with four species are regarded as opportunistic pathogens. From these, C. tropicalis, C. inconspicua and K. marxianus were the most commonly encountered. The enzyme activities of the potential pathogens assessed using API ZYM system showed that almost strains had esterase, esterase lipase, valine and cystine arylamidase, alpha chymotrypsin, alkaline phosphatase and naphthol phosphohydrolase activities. The activity of α-glucosidase was found only in C. tropicalis and C. inconspicua strains isolated from tchapalo while ß-glucosidase activity was found in all strains from tchapalo and only in C. inconspicua isolated from bangui.

Se midieron los niveles sericos de las isoenzimas de la dehidrogensas lactica (LDH) en siete pacientes de hanseniasis de la Republica Argentina. El fraccionamiento se hizo por electroforesis en gel de poliacrilamida. En todos los casos la LDH-2 resulto disminuida y la LDH-4 aumentada; la fraccion LDH-5, que fue detectada en solo tres de los casos, resulto muy elevada com respecto a los valores normales.
