In children, ABPM is mainly caused by Candida albicans, Curvularia, Pseudallescheria boydii
, and Bipolaris .

apiospermum, sexual form of Pseudallescheria boydii
) is a highly invasive and opportunistic pathogen.
The filamentous fungi Pseudallescheria boydii
(Cazarolli et al., 2012) and Aspergillus fumigatus (Bento and Gaylarde, 1996) were included to assess the specificity of the primers.
Well-characterized clinical isolates of Aspergillus fumigatus, Aspergillus flavus, Aspergillus terreus, Pseudallescheria boydii
, Rhizopus oryzae, Rhizopus microsporus, Cunninghamella bertholletiae, and Mucor circinelloides were used for endotracheal inoculation.
(asexual form, Scedosporium apiospermum) is hypothesized to be the most common fungal pathogen associated with near-drowning, although this finding has not been studied specifically in the context of disasters (30).
A subculture of the organism, preliminarily classified as Scedosporium spp., was sent to the Fungus Testing Laboratory, The University of Texas Health Science Center at San Antonio where it was identified as Pseudallescheria boydii
based upon phenotypic morphology and DNA sequencing.
DISCUSSION: Pulmonary psuedallescheriasis is caused by a ubiquitous fungus Pseudallescheria boydii
described as a human pathogen by Saccardo in 1911 .
Ademas, en abril de 2007 habia presentado infeccion de tejidos blandos en el hallux izquierdo por Pseudallescheria boydii
(Scedosporium apiospermum) sensible unicamente a voriconazol, el cual recibio durante tres meses con mejoria.
Las excepciones son Candida lusitaniae (ver cuadro 2) y algunos patogenos emergentes como Trichosporon asahii, Fusarium spp., Pseudallescheria boydii
, Scedosporium prolificans, y Paecilomyces lilacinus (ver cuadro 3) (3,34).
Culture confirmation was available in five specimens, which showed Aspergillus fumigatus in 2, Aspergillus flavus 1, Pseudallescheria boydii
1 and Candida albicans (in mixed infection) in 1.
The genus Scedosporium consists of two medically important species: Scedosporium apiospermum (and its teleomorph or sexual state Pseudallescheria boydii
) and Scedosporium prolificans (formerly S.
