• Wildlife is a potential source for emerging and re-emerging zoonotic diseases. Trichinella spiralis is the major etiological agent that causes Trichinella spp. infection in humans and domestic pigs, but other Trichinella species are also involved. Pigs are the most important source of Trichinella spp. infection worldwide, being their outdoor breeding, waste feeding, their exposure to wildlife and carcasses, the documented risk factors for pig production, food security, and health. Early Trichinella spp. detection and the study of their reservoir's competence are needed to prevent and control Trichinella spp. infection. The aims of this study were to analyze the occurrence of Trichinella spp. infection in in synanthropic and non-synanthropic wild and domestic animals in rural areas and compare Trichinella spp. infection in synanthropic and non-synanthropic wild small mammals on intensive and extensive piggeries. This is a two-year study in an endemic area of the disease. To evaluate parasite infection, we included samples from animals captured in 18 intensive and extensive piggeries and from road-killed vertebrates collected lengthwise 882 km within 13 counties along eight consecutive seasons. Trichinella spp. infection association to small mammals' infestation levels and community composition and structure was analyzed. From a total of 697 wild and domestic animals analyzed, infected Rattus norvegicus and Didelphis albiventris individuals were found in two extensive piggeries. The parasite was not found outside piggeries. Infections were identified as T. spiralis by a Nested-Multiplex PCR. These findings showed some evidence that supports the idea that extensive farming has a higher risk of transmission of T. spiralis than intensive farming.
