To further investigate this relationship, we compared adult male and female<jats:italic>Schistosoma mansoni<\/jats:italic>from malnourished and well-fed mice through morphometric and confocal laser scanning microscopy analysis. Swiss mice were fed protein-deficient diets (8%) and infected subcutaneously with approximately 80<jats:italic>S.<\/jats:italic><jats:italic>mansoni<\/jats:italic>cercariae (BH strain, Brazil). Control mice were fed a standard rodent diet (23% protein). The nutritional status was evaluated by body weight gain and albumin values. Mice were sacrificed 63 days post-infection. Recovered worms were stained with hydrochloric carmine and preserved as whole-mounts for bright-field examination and confocal microscopy. The body weight gain and serum albumin concentrations were significantly lower (<jats:italic>P<\/jats:italic>&lt;\u00a0 0.05) in malnourished mice than in controls. In general, all morphometric values of specimens grown in malnourished mice were lower than those of control mice. Schistosome worms grown in malnourished mice had statistically significant differences (<jats:italic>P<\/jats:italic>&lt;\u00a0 0.05) in the reproductive system and tegument than those grown in mice fed standard diets. In female worms, vitelline glands showed few remaining follicles and ovaries lacked mature oocytes. In male parasites, tubercles were fewer in number on the dorsal surface and testicular lobes presented fewer differentiated germinal cells. In summary, we describe novel data supporting the view that low-protein diets may influence the development of adult worms.<\/jats:p>","DOI":"10.1017\/s0022149x08067217","type":"journal-article","created":{"date-parts":[[2008,10,10]],"date-time":"2008-10-10T10:21:07Z","timestamp":1223634067000},"page":"13-21","source":"Crossref","is-referenced-by-count":7,"title":["Effects
