Abstract

Knowledge of the mechanisms of natural resistance to infection, including skin healing, allows the improvement of the cultivation of domestic and wild species, however, we could not find national and international studies on skin healing in crocodilians. Furthermore, this description is necessary due to frequent cannibalism in backyard alligators. Injuries caused by cannibalism, among other things, act as gateways for infections, and thus decrease the performance of alligators in the fattening and egg laying. Furthermore, these lesions represent a favorable situation for the emergence of animal diseases, thus depreciating the value of the meat and skin. These studies of regeneration and healing are essential to guide the management of animals. It should be noted also that little is known about the histological structure of alligator skin, and its annexes, with the need for a detailed description of histological and histochemistry of this organ, since the alligator skin is highly valued in the international market. This paper aims to describe the histology of the skin, as well as the kinetics of skin healing histophysiology, creating conditions favorable for the improvement of management practices in cultivation.
