Análise microscópica do estágio de ossificação do gambá (DIDELPHIS SP.) em diferentes estágios fetais através da diafanização e do exame radiográfico

Abstract

Opossums (Didelphis sp.) Are marsupials that have a very short gestation period, therefore, their offspring are born immature and will end their development in the mother's marsupium. Because they are very early in their development, in the fetal stage of these animals, they already have premature growth of their organs and tissues as a whole. The objective of this work was to describe the ossification stages of opossum fetuses (Didelphis sp.) At different postnatal stages, through diaphanization and radiographic examination. One animal of each age (5 days, 15 days, 22 days and 35 days) was used to verify ossification and consequent comparison with other domestic species. The results indicate a premature ossification of the species in the fetal stage, unlike domestic animals.
