Chapter I - The obligate intracellular parasite Toxoplasma gondii is the causative agent of toxoplasmosis, a disease that affects humans and generates economic losses in farm animals. When prevention fails disease refers to the diagnosis and subsequent treatment if the individual is diagnosed as positive. Therefore, the development of new accurate diagnostic tools for detecting T. gondii infection is a need in particular to determine the environmental source of infection which can result in more appropriate public health policies against different routes of infection and prevent potential damage that toxoplasmosis can cause when animals are infected. Chapter II - The domestic chicken (Gallus gallus domesticus) are considered epidemiological sentinels, still representing a major source of recombinant strains when predated by cats, it is common to find them with multiple infections. We evaluate the diagnostic potential of six synthetic peptides (SAG2Y, MIC1, M2AP, GRA10, ROP2 and ROP7) predicted in silico from tachyzoites immunodominant markers of T. gondii in samples from naturally infected chickens, comparing synthetic peptides with antigen total soluble (STAg). In general, our results demonstrated that reactivity rates and positivity for these peptides are similar to the STAg, and the ROP7 peptide and the combination of peptides MIC1+ROP2 have significant sensitivity, confirming them as potential diagnostic tools for the diagnosis of toxoplasmosis in chickens. Chapter III - Sheep (Ovis aries) are commonly infected with Toxoplasma gondii due to his eating habits. Infection in pregnant sheep can have serious consequences such as embryonic death, fetal resorption, mummification, and neonatal death. One concern regarding the infection in these animals is that the meat can be a source of contamination to humans and other carnivores. Therefore perform accurate diagnosis in these animals is of fundamental importance. In the present study we evaluated the potential of new synthetic peptides as a diagnostic tool. Synthetic peptides (SAG2Y, SRS52A, MIC14, GRA4, GRA10 and GRA15) were predicted in silico from immunodominant proteins of T. gondii. We determine the levels of IgG antibodies using sera obtained from two farms in the city of Uberlândia. Analyzing the results together, the peptide combination GRA10+GRA15 (Accuracy = 0,82) showed better characteristics compared with the other mixtures. This preparation could be better analyzed with an antigenic mixture potential use in the diagnosis of toxoplasmosis in sheep and other species.

This dissertation analyzed the existing work on travestility and transsexuality whose problematic research focused on issues related to health and / or health services. For this purpose, a Literature Review Systematized Descriptive in virtual databases was performed: Bank of Higher Education Personnel Improvement Coordination Thesis (CAPES), Brazilian Digital Library of Theses and Dissertations (BDTD), Scielo and PubMed, between the years 1997 and 2014 in Brazil. We used the search terms "transsexual," "transvestite" and "transgender", each associated with the search term "health", in Portuguese and English. Complementing this search, we used the Documentary Analysis methodology to assess pamphlets productions, institutional documents and non-governmental organizations (NGOs), which were incorporated into the discussion. 295 papers were identified, among theses, dissertations and scientific articles. Of these, 223 were excluded and 72 selected for analysis. Thus, it obtained five theses and dissertations 21 on the topic of travestility and 7 theses and dissertations 9 that deal with transsexuality. Among the selected papers, 16 deal with transsexuality and health, 5 address the issue of travestility and health and work, 9 refer to the term "transgender" and "health". Even though it is an emerging field of research, there is an apparent deviation of the speech, previously anchored in questions whose topics are related to confrontation, infection or illness by HIV / AIDS (level of specialized care) for discussions on the health care for transsexuals in the process (level of specialized care). Still, few papers have specific trans attention in primary care associated with a comprehensive health care, with the empowerment of individuals, respecting the power of life, which are configured as important issues for the Public Policy on Health today.
