A. Sano et al., Comparison between human and armadillo Paracoccidioides brasiliensis isolates by random amplified polymorphic DNA analysis, MYCOPATHOLO, 143(3), 1998, pp. 165-169
Sixty-three Paracoccidioides brasiliensis isolates obtained from three nine
-banded armadillos (Dasypus novem-cinctus), one Amazonian armadillo's and 1
9 clinical isolates were compared by random amplified polymorphic DNA analy
sis with the primer OPG-19. The isolates were divided into three major clus
ters, I, II and III. Coincidences between human and armadillo isolates were
observed in clusters I and II. Cluster III consisted only of armadillos' i
solates. The results suggested that (I) humans may acquire P. brasiliensis
infection by contact with armadillo's environment, (II) there may be P. bra
siliensis genotypes peculiar to the animal, and (III) individual armadillos
may be infected with P brasiliensis cells with different genotypes.
