- Laboratory animals are essential in research. Genetic and health quality control enables reliable and reproducible experimentaldata. A very common disease in rodent colony facilities, is a parasitosis caused by the etiological agent, species: Syphacia muris, whichbelongs to the filo: Nematoda, to the family: Oxyuridae, is an intestinal endoparasite. The life cycle of this parasite is direct, (there isno intermediate host) has a cycle of 7 to 9 days. Syphacia muris Las infections can alter a humoral host´s response to parasitic antigenic stimuli, and cause a Th2-like immune response with the production of elevated cytokines and induce an autoimmunity mediatedby Th2 [1]. Therefore a study was carried out in colonies of rats Wistar strain (adult males and females) of a conventional animal carefacility of faculty of medicine of the University of Buenos Aires. A total of 36, 32 y 30 rats were tested. Random samples were takenfrom animals, by Graham´s method. Treatments were: treatment A: Ivermectin administered subcutaneously according to the weightof the animal, every 15 days. Treatment B: Ivermectin administered subcutaneously according to the weight of the animal, each week.In treatment C: Ivermectin was administered orally in drinking water at a concentration of 2ml ivermectin in 500ml of filtered water,for four days and allowed to rest for 3 days, this treatment was repeated for three weeks. Together, spray cage spraying containing anivermectin solution was performed: 1ml in 250 ml of filtered water. The calculated prevalence rate for each treatment was: treatmentA: in the first dose 50% and in the second dose of 75%. In treatment B: a 75% rate was obtained at the first and second doses of 80%.In treatment C: it was 0% in the first and second doses. These results enabled the finding of adequate and effective treatment for theeradication of oxyides. A parasitosis very common and common in all biotheres, but so untreated. Therefore, this work demonstratedthat it is possible to be treated, eradicated and controlled to avoid interference and alter experimental responses. However, ensuremore reliable results by controlling some variables, such as the health status of animals. Obtaining a good experimental model, applying the uses of 3Rs [10], in terms of reduction when treating infected animals and avoiding the subsequent use of other animalsand in refinement when ensuring the welfare of animals.
