Abstract

"The microspore is protozoa, forced intracellular parasite, of different animal species. They belong to the Phylum Microspore, which produce very small spores and lack mitochondria. One of the microspores, there exists the Encephalitozoon cuniculi, which is an emergent opportunistic parasite, In the prevalence ofE. cuniculi in rabbits, ranks from 15 to 76 % at worldwide level are reported With the purpose of detecting the presence of this parasite in our country, the search of this one was made, in the parasitology laboratory of the Institute of Public Health of Chile (ISP). The sample was constituted by 100 normal rabbits without distinction of sex, pertaining to: Bioterio of ISP, familiar deposits from Pirque, ""Mundo Granja "" of the University of Chile and a commercial deposit. All the rabbits were previously evaluated by means of a clinical examination. After processing the sample of deposition and tinkles, they were dyed with trichromic colorants: Cromotropo 2R and Gram Cromotropo. A positive result was obtained in 55% of the individuals, where the greater percentage appears in inmunosuppressed rabbits and conventional raising rabbits. The objective of this study is to contribute to the health, in special the human being health, as well as the animals, determining the presence ofE. cuniculi in rabbits of different origins."
