[Optimization of the conditions for RAPD-PCR of Candida spp. and Cryptococcus spp].

In this study, we determined the optimal RAPD amplification conditions to obtain genetic molecular markers for the rapid and accurate identification of Cryptococcus spp. and Candida spp. The following parameters are modified: template DNA, DNA polymerase, magnesium cloride and primer concentration; denaturation, annealing and extension time, temperature of annealing and thermal cycles.

Population structure in the endangered Blanca Cacereña bovine breed demonstrated by RAPD analyses.

RAPD analyses have been used to determine the genetic diversity and the population structure of the endangered Blanca Cacereña bovine breed. Genetic variability was evaluated on the basis of 1048 loci produced by 71 primers. RAPD produced a number of polymorphic loci (30.

Genetic variability in the Iberian imperial eagle (Aquila adalberti) demonstrated by RAPD analysis.

RAPD analysis was used to estimate the genetic diversity in an Iberian imperial eagle (Aquila adalberti) population, one of the most threatened bird species in the world. Forty-five of 60 arbitrarily designed primers amplified 614 loci in 25 individual eagles, 59.7% of which were polymorphic.

Rapid and easy method to extract and preserve DNA from Cryptococcus neoformans and other pathogenic yeasts.

The mucopolysaccharide capsule of Cryptococcus neoformans and other pathogenic yeasts prevent the extraction of DNA from these important zoonotic agents. We report that the use of a lysis buffer containing a high concentration of urea is an easy, efficient and time-saving technique to obtain high yields of good-quality DNA for molecular diagnosis. The use of urea also prevents the degradation of DNA during storage of samples at room temperature for up to 6 months.
