The emerging diseases in the different animal species require the necessary attention, to carry out actions that diminish their diffusion in animal populations. The aim of this study is to provide a current reference on coenurosis a wild rabbit (hare), and determinants of its presentation on animal health, which can put at risk man´s health. A sample of muscle tissue was evaluated and a hydatid cyst (3 x 6 cm) was obtained from a wild rabbit. The tissue was punctured, extracting transparent aqueous liquid discarding an abscess or hematoma. Content analysis showed the presence of many scolices, corresponding to coenuro Taenia serialis. In the histological preparation it was observed: muscle tissue, connective tissue fibroblasts and an inflammatory surrounding area composed of eosinophils and lymphocytes which in turn limited the parasite scolices. This finding representes an important condition to evaluate the natural environment of wild animals in the area, due to the risk of dissemination and contamination of plants and animals of the área, even though, may not be of of public health importance, unless meat of wild rabbits gets eaten.
