Abstract—The study was conducted at El-Kala National Park, located in the far northeast of Algeria. This national park contains a mosaic of habitats that make it the environment of several interactions, it is also a good site for studying the degree of adaptation and evolution of species that live in it. This park has also suffered from many forms of natural and man-made degradations, the most important of which are fires and the environments’ fragmentations for the farms settlement. The black rat - Rattus rattus – is a very common and cosmopolitan species, It came from Asia, and managed to colonize all types of terrestrial environments; This could translate a behavioral great adaptive power and a genetic closely turned adaptation, which deserve to be studied. The protection and the safeguarding of the fauna require a general knowledge of its ecology or specifically of its cell biology. Halfway between cell biology, anatomy, biochemistry and physiology, histology aims to explore the structure of living organisms, the constitutive and functional relationships between their functional elements, as well as the tissues renewal. It participates in the exploration of pathological processes and their effects. This study represents a histological diagnosis of the state of health of the black rat reproductive organs in northeastern Algeria. In fact, of the twenty-six organs examined, no pathology was diagnosed except for one functional cyst and a beginning of infertility noticed in the elderly subjects.
