EXPERIMENTAL INFECTION OF ONE-MONTH-OLD PIGLETS WITH SPORES OF ENTEROZYTOZOON BIENEUSI

EXPERIMENTAL INFECTION OF ONE-MONTH-OLD PIGLETS WITH SPORES OF ENTEROZYTOZOON BIENEUSI

Human microsporidiosis has been considered a disease of the VIH positive patients or other patients with immunosupression. At present, it is known that microsporidiosis affects not only these patients but also the immunocompetent. The most common species is the Enterocytozoon bieneusi. The present study demonstrates the experimental oral infection of one-month-old piglets with spores of E. bieneusi. Nine piglets from a commercial farm with very low risk of infection by this parasite were used. Two staining techniques were utilized for the diagnosis of the parasite: Tricromic Blue Stain (in fecal samples) and Silver Stain (in intestinal wall). Spores of E. bieneusi were observed in feces and intestinal sections of all animals. The estudy showed that pigs of one month of age are susceptible to the infection with spores of E. bieneusi and therefore, could be considered as experimental model in the study of the human microsporidiosis caused by E. bieneusi.

La microsporidiosis humana era considerada una enfermedad exclusiva de personas VIH positivas o de pacientes inmunocomprometidos pero actualmente se sabe que afecta, además, a pacientes inmunocompetentes. El microsporidio más común es el Enterocytozoon bieneusi. El presente trabajo tuvo como objetivo demostrar la infección experimental de cerdos de un mes de edad con 840 000 esporas de E. bieneusi por vía oral. Se utilizaron nueve lechones procedentes de una granja tecnificada con muy pocas probabilidades de infección a este parásito. Para el diagnóstico del parásito se utilizó la coloración tricrómica (en heces) y la coloración de plata (tejido intestinal). Se logró observar esporas de E. bieneusi en heces y en cortes de intestino de todos los lechones. El trabajo demostró que los cerdos de un mes de edad son susceptibles a la infección con esporas de E. bieneusi y, por lo tanto, este animal podría ser considerado como modelo experimental en el estudio de la microsporidiosis humana causada por E. bieneusi.
