dc.description	It is common to find dead amphibians who are in danger of extinction and live in conservation centers. This problem can occur from not knowing their hygiene status, which affects in a negative way on the conservation programs and subsequently during their reintroduction. In Ecuador there is a conservation initiation called “Balsa de Sapos” which keeps in captivity the frog species known as Atelopus limon that currently find itself in wild life decline, making them optimal for captivity conservation. However, during the ex situ breeding process, death is occurring to this species of amphibian and the causes of it do not reach a diagnosis. The histopathological study was performed on 14 individuals (11 females and 3 males) which died in 2014. The tests that were performed on the individuals were a general physical examination, biometry and subsequently a necropsy. Samples from every organ were taken and conserved in buffered formaline at 10 percent for later making histological plates. The findings from the principal and secondary histopathological analysis and lecture were done by light microscopy. The injuries were classified in primary, secondary and to be characterized as circulatory, degenerative, inflammatory of infectious and non-infectious origin and manifested acutely and chronically. The possible dead causes for this population were 71.42 percent (10/14) by cardiogenic shock, 21.43 percent (3/14) by hypovolemic shock and 7.14 (1/14) were undertermined. The secondary organs presented Entamoeba spp. which were the 14.28 percent (2/14) and Batrachochytrium dendrobatidis 21.43 percent (3/14). This study allowed us to know the origin of the causes mortis and these were related to a physiological compensation to an environmental hypoxia, hyperemia, hemorrhage and infectious agents that affect this population during the captivity.	en
