Double-stranded RNAs (dsRNAs) with molecular masses 1.7 and 5.0 kbp, respectively, were isolated from the strain Cryptococcus hungaricus CBS 6569. The dsRNAs were copurified with eicosahedric virus-like particles, 29 nm in diameter. This strain produced a protease-sensitive 'toxin' which inhibited the growth of strain C. hungaricus CBS 4214. The toxin had maximum activity at pH 3.7. The highest toxin amount was attained after a culture period of four days.
In recent years, biochemical and immunochemical procedures used for rapid diagnosis of microbiology have advanced. In particular, methods using immunochemical procedure are commonly used. Latex agglutination test, enzyme immunoassay and immunochromatographic methods having more simple and high sensitivity have also been used. These methods are routinely used to detect Helicobacter pylori, Group A Streptococcus and others. Furthermore, in routine examinations, endotoxin and (1two head right arrow3)-beta-D-glucan have been measured as markers that detect gram-negative bacteria and deep fungus. Currently, there are many infections including new and previous infections. These techniques should be applied for detecting a larger number of microbiology.
A novel species of the basidiomycetous genus Cryptococcus is described as Cr. yarrowii based on the study of an isolate from a decayed mushroom collected in Portugal. DNA-DNA homology with the type strain of the phenotypically similar species Cr. albidus was 10 +/- 2%.
