TITLE:

Foetal development of urogenital system in Cuniculus paca from Amazon region

KEY WORDS:

SUMMARY:

The species Cuniculus paca is a small rodent distributed throughout most of Latin America, its role in seed dispersal, commercial exploitation and meat subsistence makes it a species of important human and forest dependence. Therefore, the objective was to morphologically characterize the urogenital apparatus of Cuniculus paca fetuses, correlating it with their respective intrauterine developmental stages. We used 12 fetuses, between 48 and 157 days old, obtained from the collection of free-living adult specimens in the Peruvian Amazon, in partnership with a participatory fauna management program. The specimens were fixed and dissected for morphometric, macroscopic and histological analysis. In morphometric analysis the kidneys showed no three-dimensional growth correlated with age, morphologically the urinary tract was composed of two kidneys, two ureters, one bladder and one urethra, the kidneys were defined as smooth surface organs, The kidneys were defined as smooth-surfaced organs, being related craniomedially with the adrenals and caudally with the gonads. Histologically, the kidneys presented a good distinction between the cortical and medullary regions, with the presence of glomeruli from the first evaluated age, increasing in size and number according to the fetal stage. Pacas in the fetal phase have a well-developed morphology of the urinary tract, whose observed particularities are important characteristics of the precocial species.
