SUMMARY:

Epidemiological studies of emerging and reemerging diseases must consider the components of the epidemiological triad in an integrated manner and consider the health emergency as a shared problem of One Health. In this context, the infectious agents Toxoplasma gondii and Sporothrix spp. are inserted, where humans and susceptible animals can become infected through contact with a contaminated environment and/or infected animals. Therefore, the objective was to evaluate the contamination by oocysts of T. gondii in soil samples from public environments in the city of Recife and the Fernando de Noronha Island and apply the Ecological Niche Modeling to predict the environmental suitability of the archipelago for coccidia permanence. In addition to investigating population structure of species of the genus Sporothrix in humans and animals, as well as the spatial distribution of sporotrichosis cases in cats in the Metropolitan Region of Recife. For this, three experiments were carried out that composed three chapters of the qualification referring to the study of T. gondii in the soil and the partial results on the genetic diversity of Sporothrix spp. In the first study, 120 soil samples collected in 24 places such as squares, parks, universities and hospitals in the city of Recife, were analyzed in which the Apicomplexa protozoan gene was identified in nine sampled sites, with similarity in the sequencing for T. gondii.. The second study included the 15 neighborhoods of the Fernando de Noronha island and its four main squares, totaling 19 locations. In four of the 19 sampled sites, positive samples were obtained and in two of them we confirmed the viability of T. gondii oocysts. It was also confirmed the suitability of the entire length of the Archipelago for the maintenance of coccidia through ecological niche models. In the third study, it was demonstrated that Sporothrix brasiliensis is the prevalent species as well as the mating idiomorph MAT1,2. A total of 1176 cases of sporotrichosis in cats were recorded in the period of six years in the Metropolitan Region of Recife, with a greater share of cases of cats coming from the cities of Olinda, Jaboatão dos Guararapes and Recife. The results obtained in these studies contribute with important epidemiological information that serve as a basis for the development of public policies aimed at Toxoplasmosis and Sporotrichosis.
