Parasitological and morphological study of Schistosoma mansoni and diabetes mellitus in mice

► The average load of adult worms was lower in diabetic mice than in non-diabetic mice. ► No morphological divergences in either tegument or reproductive organs were observed between above groups. ► Morphometric analysis did not show differences between worms recovered from diabetic or non-diabetic mice. ► Diabetic mice displayed higher tissue immature eggs than non-diabetic mice. ► Diabetic mice displayed lower fecal egg count than non-diabetic mice.
