Snake venoms are composed of complex active substances, most of them of protein nature, causing various effects on humans and domestic animals and can lead to death. Philodryas nattereri is a native snake Ceara region, found throughout the state. This study aimed to know the morphological and physiological changes in mouse skin after inoculation with the total venom this serpente. The animals were divided into two groups that received concentrations of 40μg/mL and 20μg/mL respectively, inoculated subcutaneously, and a third group that received intradermal 40μg/mL of the venom. The macroscopic results showed the presence of a crust in the inoculated area, and the presence of bleeding, this activity was confirmed by histopathological analysis. Microscopically, all experimental groups had lymphoblastic and polymorphonuclear inflammatory infiltration, hemorrhage, edema, and fibrosis. The venom of the snake Philodryas nattereri altered the normal integument architecture. Our results corroborate to demonstrate such changes, since this toxic substance of animal origin present in our Northeast biodiversity presents few literature data, thereby being an important tool for the study of morphological and physiological changes in the skin.
