Protozoarios parásitos de importancia en salud pública transportados por Musca domestica Linnaeus en Lima, PerúParasite protozoa of importance in public health picked up by Musca domestica Linnaeus in Lima, PeruMartín Cárdenas y Rosa Martínez* ResumenEl presente trabajo investiga los protozoarios parásitos de importancia para la salud pública transportados por Musca domestica. El estudio se llevó a cabo entre los meses de junio y diciembre de 1998, en los distritos de Comas y San Juan de Lurigancho de la provincia de Lima. Se estudiaron 3014 moscas colectadas en la basura acumulada en la vía pública de los pueblos jóvenes de los distritos mencionados. Las capturas se agruparon en lotes constituidos por un promedio de 30 moscas. Se estudiaron un total de 100 lotes. Las moscas fueron disecadas y procesadas con agua destilada estéril para obtener un macerado intestinal. Para la observación de los parásitos se utilizó el método directo simple y la coloración tricrómica de Gomori ácido resistente modificado. Se encontraron los siguientes protozoarios que parasitan al hombre: Blastocystis hominis (9,0%), Giardia lamblia (3,0%), Cryptosporidium sp. (2,0%), Cyclospora cayetanensis (1,0%), Iodamoeba bütschlii (17,0%), Endolimax nana (5,0%) y Chilomastix mesnili (3,0%). Se reporta por primera vez para el Perú a B. hominis y Cyclospora cayetanensis en M. domestica. Palabras claves:Musca domestica, protozoarios, salud pública, Lima. AbstractAt the present work we had investigated protozoa parasite picked up by Musca domestica. Surveys were carry out between June and December 1998 in districts of Lima (Comas and San Juan de Lurigancho). A total of 3014 flies were collected around garbage accumulated in the streets. Each survey were considered a lot with a mean of 30 flies. A total of 100 lots were studied. The flies were dissected and processed with sterilised distilled water for obtain the intestinal macerated. Observations were made by the simple direct method and with Gomori trichromic stain modified acid-fast. The following protozoa parasites of human were found: Blastocystis hominis (9,0%), Giardia lamblia (3,0%), Cryptosporidium sp. (2,0%), Cyclospora cayetanensis (1,0%), Iodamoeba bütschlii (17,0%), Endolimax nana (5,0%) and Chilomastix mesnili (3,0%). B. hominis y Cyclospora cayetanensis were reported for the first time in M. domestica from Peru.

RESUMEN ABSTRACTThe goal 01 this research was to increase the knowledge 01 two parasitic protozoa: Her muscarum (Leidy, 1856) Ken, 1880 and Octosporea muscaedomesticae Flu, 1911, in Musca Both represent new records in Peru .The H. muscarum leptomonad are 36 ~ long and are larger than the ones cited by other musca domestica e presents large and plasmodial forms slightly larger than the ones studied b & Vávra (1998).In the M. domestica group surveyed, we determined a significant percentage of H. muscaru and o. muscadomesticae (27,0%).
