Giardiasisis a cosmopolitan infection, it's prevalence around the world vary between 0.5 and 50%. Its prevalence averages about 15% in Latin America's rural population. Because there is very little information on the prevalence of Giardia infection in our city, we decided to investigate giardiasis prevalence in preschool children of Tiabaya`s district kindergartens, Arequipa province, Peru. Children`s parents were interviewed and fecal samples were collected from 104 children. Samples were processed by modified Teleman technique. The prevalence of Giardia intestinaliswas 25.96%; 70.37% of samples had a single parasite and 29.63% had other parásites. Most of the cases came from rural places with inadequate rubbish elimination. Diarrhea and appetite diminution were the most common symptoms.

El presente estudio se realizó en escolares del distrito de Cabanaconde, provincia de Caylloma- Arequipa-Perú para determinar la prevalencia de parasitismo intestinal en escolares y determinar los factores de riesgo que condicionan dicho parasitismo. El estudio estuvo conformado por 202 escolares de 5 a 18 años de los cuales sólo 135 alumnos cumplieron con los criterios de inclusión para realizar el estudio (66,83%). Se coordinó previamente con el director, profesores, padres de familia y alumnos a quienes se les brindó una charla informativa y de sensibilización sobre el tema haciendo uso de diapositivas, banner, trifoliados y volantes. Se aplicó una ficha epidemiológica conformada por cinco ítems: edad, sexo y grado de estudios, saneamiento ambiental, hábitos higiénicos y comportamiento alimenticios. Las muestras fueron procesadas mediante el método de Teleman modificado....

The present study was done, from May to August 2006 in Pucchun, a town located in Arequipa-Peru, Camana Province, Mariscal Caceres District. One fecal sample and epidemiological dates were obtained from each of Pucchun's Primary School students. Fecal samples were processed by modified Teleman technique and fast sedimentation. 92.68% of samples had one or more intestinal parasites, predominantly protozoa: Entamoeba histolytica/ Entamoeba dispar (33.17%), Giardia intestinalis (31.71%), Hymenolepis nana (47.17%), Diphyllobothrium pacificum (0.49%) and Fasciola hepatica (0.49%). Polyparasitism (42.63%) was more frequently encountered. Non pathogen parasites were also present and included Entamoeba coli (72.68%), Blastocystis hominis (48.29%), Endolimax nana (35.61%), Iodamoeba butschlii(23.90%), and Chilomastix mesnilli (16.58%). Epidemiological factors found were: age between 8 and 10 year...

Peru is one of the countries with the greatest regional distribution of human fascioliasis caused by F. hepatica in the world, it was considered an emerging disease and can have high morbidity. We present the case of a 41-year-old woman who presented with abdominal pain. Ultrasound showed cholelithiasis and choledocholithiasis; and the cholangioresonance study showed bile duct dilation and distal stenosis. A retrograde endoscopic cholangiopancreatography was made and we removed two parasites similar to hepatic flukes. Subsequently, the cholecystectomy could not be performed due to delay and request for voluntary discharge. In our environment, even today, there is a need to suspect fascioliasis, in the case of a compatible clinical of choledocholithiasis in patients from endemic regions. Therefore, knowing the best study alternatives and appropriate treatment according to the phase of the...
