RESUMO
A computer software for image (IMAGE PRO PLUS, MEDIA CYBERNETICS) was utilized in male and females adult worms aiming the morphological characterization of Schistosoma mansoni samples isolated from a sylvatic rodent, Nectomys squamipes and humans in Sumidouro, Rio de Janeiro, Brazil and recovered from Mus musculus C3H/He. The following characters for male's testicular lobes were analyzed number, area, density, larger and shorter diameter, longer and shorter axis and perimeter and extension; for females area, longer and shorter axis, larger and smaller diameter and perimeter of the eggs and spine; oral and ventral suckers area and distance between them in both sex were determined. By the analysis of variance (one way ANOVA) significant differences (p<0.05) were observed in all studied characters, except for the density of testicular lobes. Significant differences (p<0.05) were detected for all characters in the female worms. Data ratify that sympatric isolates present phenotypic differences and the adult female characters are useful for the proper identification of S. mansoni isolates.
