Resumen Se intentó la infección de lauchas mediante inhalación en aparato dePiggott &Emmons, con conidios pigmentados deSporothrix schenckii partiendo de maderas artificialmente contaminadas en el laboratorio. En una primera experiencia las maderas infectadas fueron colocadas en el fondo del aparato. No se logró infectar ninguno de los 14 animales inhalados. En una segunda experiencia las maderas fueron colocadas suspendidas dentro del matraz y además se introdujeron cristales de cloruro de calcio para disminuír la cantidad de vapor de agua. Se comprobó un mayor desprendimiento de esporos con relación a la experiencia preliminar y en dos de los 20 animales inhalados se logró cultivarS. schenckii a partir de pulmón en uno y de higado y bazo en otro. Se deduce la dificultad de infectar lauchas con conidios pigmentados del hongo por este procedimiento. Estos resultados concuerdan con la rareza de la puerta de entrada pulmonar en la esporotricosis.
Notes:
Summary We have tried to infect mice by inhalation with pigmented conidia ofSporothrix schenckii, in an apparatus ofPiggott &Emmons using pieces of wood artificially contaminated in the laboratory. In a first experiment the infected pieces of wood were placed in the bottom of the flask. We could not infect any of the exposed animals. In the second experiment the pieces of wood were suspended inside the flask and moreover, calcium chloride crystals were used to avoid humidity. A much higher liberation of spores was observed as comparing with the first experience. In two out of the 20 animals positive cultures ofS. schenckii were obtained from the lungs of one and from the liver and spleen of the other. We infer the difficulty in infecting mice with pigmented conidia of the pathogen by this procedure. It is presumed that these results agree with the rarity of the pulmonary forms in sporotrichosis.
