Fifteen isolations of Gymnoascus demonbreunii from canine and soil sources

Zusammenfassung: | Eleven isolations of Gymnoascus demonbreunii were obtained from a total of 265 dogs which were killed and tissues cultured for Histoplasma capsulatum. Seven of these isolates were obtained from lung tissue and 4 from mediastinal lymph nodes. The occurrence of this fungus in dogs is thought to be incidental because there were no lesions present nor fungal multiplication in the tissues since the highest number of colonies obtained from one organ was 9 and in the majority of cases only 1. H. capsulatum was isolated in addition to G. demonbreunii from 4 of the above 11 animals.
Four isolates of G. demonbreunii were obtained from soils collected from chicken houses where H. capsulatum has also been isolated.
After numerous studies, no relationship could be shown between G. demonbreunii and H. capsulatum with the exception of perhaps an environmental one.
Resumen
De un total de 265 perros autopsiados, cuyos tejidos fueron cultivados para la investigación de Histoplasma capsulatum, se obtuvieron once aislamientos de Gymnoascus demonbreunii.
Siete de tales aislamientos fueron logrados de pulmón y cuatro de ganglios linfaticos mediastíncos. La presencia de este hongo en perros se cree casual ya que no se comprobaron lesiones ni tampoco evidencia de multiplicación del hongo en los tijidos y ademas el número mayor de colonias obtenidas a partir de un órgano fue nueve y en la mayoría de los casos sólo una.
H. capsulatum fue aislado junto a G. demonbreunii de cuatro de los 11 animales citados.
Cuatro cepas de G. demonbreunii fueron obtenidas de suelos procedentes de galineros de los cuales había sido también aislado H. capsulatum.
Después de numerosos estudios, no es posible establecer ninguna relación entre G. demonbreunii e H. capsulatum, except desde el punto de vista del medio ambiente. |
