- Impacto de la dieta sobre la inducción de infección con quistes de Giardia lamblia en ratas Sprague-Dawley Martha Elvia Díaz Nydia Ballesteros Rosalba Pérez Verónica Mata Salud Mexico Giardia lamblia nutrition disorders Key words: giardiosis Objective. To assess the effect of malnutrition on the developmentof giardiosis in Sprague-Dawley rats, using differentinoculum sizes of Giardia lamblia cysts. Material and Methods.An experimental study was conducted between 1995 and1999 at Centro de Investigación, Alimentación y Desarrollo(Center for Research, Food, and Development), inHermosillo, Sonora, Mexico. The study population consistedof two groups of six to eight experimental units thatwere fed two different diets and inoculated five differentconcentrations of Giardia lamblia cysts. Data were collectedon excretion of cysts, weight gain, food intake, bowel contents,and macro and microscopic lesions in the intestinalmucosa. Statistical analysis consisted of analysis of varianceand residuals. Results. Animals fed with a diet meeting nutritionalrequirements required an infecting inoculum of 60cysts, while malnourished rats required only six cysts todevelop mucosal lesions. Conclusions. Weight gain monitoredduring ten days was not a good indicator of Giardialamblia infection. Infection depended on cyst inoculum sizeas well as on the nutritional status of the tested animals.The English version of this paper is available at: http://www.insp.mx/salud/index.html 2002 artículo científico 0036-3634 https://www.redalyc.org/articulo.oa?id=10644404 en http://www.redalyc.org/revista.oa?id=106 Salud Pública de México application/pdf Instituto Nacional de Salud Pública Salud Pública de México (México) Num.4 Vol.44
