During 4 months, and while conducting an environmental sampling of air, 2 cases of aspergillosis by
The aim of this study was to know the variability and the genetic relationship between the clinical and environmental isolates, obtained in the oncohematological center.
Two genotyping techniques of different discriminatory power (RAPD and AFLP) were used. A genetic similarity matrix was calculated using Jaccard method and was the basis for the construction of a dendrogram by UPGMA. The level of genetic variability was assessed by measuring the percentage of polymorphic loci, number of effective allele, expected heterocygozity and association index test
The dendrogram reveals that the
Patients 1 and 2 were not infected with isolates from the nosocomial environment. Clinical and environmental isolates of
