ABSTRACT

El propósito de este estudio es entregar información sobre la situación de la fasciolosis en los equinos fina sangre de carrera del Club Hípico Concepción (Región del Bio-Bio, Chile). Se tomaron muestras de 269 equinos (92 hembras y 177 machos), con un rango de edad entre 2 y 11 años. En cada uno de los animales, se obtuvo una muestra de heces, la que fue analizada mediante examen de sedimentación para detectar la presencia de huevos de Fasciola hepática. De los 269 equinos examinados, se detectaron 28 (10,41 por ciento) positivos aF hepática. Se encontraron sólo diferencias de infección por edad, siendo los menores los que presentaron mayores prevalencias (p < 0,05).


The purpose of this study was to add information about current situation of the Thoroughbred racehorses fasciolosis in Chile. The study was made between January and February 2006. Fecal samples were taken from 269 horses (92 females and 177 males), whose age ranges from 2 and 11 years. And they were analyzed by means of sedimentation examination in order to find the presence of Fasciola hepßtica eggs. The coproparasitologic study was complement with a survey to the horse trainer. For the analysis of the results we used the statistical test of percent² and Fisher exact test. We detected 28 (10,4 percent) positive to the F. hepßtica eggs. Significant differences were found (p < 0,05) by age and between the animals that received flukicide drug treatment and the not treated.

ABSTRACT

Se analizó la fauna parasitaria de 21 tiuques (Milvago c. chimango) de la ciudad de Chillán (36° 34' S- 72° 06' O). Se reportan tres especies de Nematoda (prevalencias entre paréntesis): Porrocaecum depressum (Ascarididae) (38,1 ± 10,6%), Cyrnea (Procyrnea) spinosa (Habrone-matidae) (52,4 ± 10,9%) y Capillaria tenuissima (Capillariidae) (71,4 ± 9,9%). No se reportaron especies de Trematoda, Cestoda, Protozoa ni Trichinella. No se observó lesión histológica atribuible a parásitos gastrointestinales.

ABSTRACT

En la provincia de Ñuble (Chile), entre Noviembre de 1994 y abril de 1995, se examinaron 235 tórtolas (Zenaida auriculata) para detectar endo y ectoparásitos. Los siguientes endoparásitos fueron aislados (prevalencia en por ciento): Killigrewia delafondi (9,4 por ciento), Raillietina sp. (1,7 por ciento), Echinostoma sp. (0,9 por ciento), Heterakis gallinarum (0,4 por ciento) y Eimeria labbeana (5,5 por ciento). Los ectoparasitos identificados correspondieron a: Falculifer isodontus (55,7 por ciento), Diplaegidia columbae (73,2 por ciento), Amblyomma sp. (5,1), Columbicola baculoides (64,7 por ciento), Bonomiella sp. (8,5 por ciento), Hohorstiella sp. (4,7 por ciento) y ácaros de la familia Trombiculidae (6,8 por ciento). Ácaros de la familia Trombiculidae, el cestodo K. delafondi y el protozoo E. labbeana habían sido registrados previamente en Chile. Los otros nueve parásitos representan el primer registro para tórtolas en Chile.

ABSTRACT

The frequency of trichinosis was determined in 300 dead persons, residents in the provinces of Concepción and Arauco, and requiring necropsy at the Servicio Medico Legal of Concepción. Diaphragm muscle samples were taken from june 1996 to march 1997. The diagnosis was made by trichinoscopy and artificial digestion techniques. Five samples (1.67 percent) were positive. There was not differences between sexes. Positive cases were found mainly among 30 to 49 years old people belonging to middle-lower class. Both diagnostic techniques showed diferent sensitivity as a consequence of the parasitic load and on the contrary, the artificial digestion was less sensitiva when the cyts were fully calcified
