9. MAPEAMENTO E DELEÇÃO DE EPÍTOPOS LINEARES DE LINFÓCITOS B EM PROTEÍNAS DO VÍRUS DA SÍNDROME RESPIRATÓRIA E REPRODUTIVA DOS SUÍNOS PARA A PRODUÇÃO DE UMA VACINA DIFERENCIAL / MAPPING AND DELETION OF B-CELL LINEAR EPITOPES IN PROTEINS OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS FOR THE PRODUCTION OF A DIFFERENTIAL VACCINE
Porcine reproductive and respiratory syndrome virus (PRRSV) was isolated for the first time in 1991 and since then it has been associated with significant economic losses to the pig industry worldwide.

10. RELAÇÃO DE RESULTADOS SOROLÓGICOS DE ENSAIO IMUNOENZIMÁTICO (ELISA) COM A TÉCNICA DE IMUNOFLUORESCÊNCIA MICROSCÓPICA DIGITAL PARA PESQUISA DE ANTIGLOBULINA IGG DE TOXOPLASMA GONDII
Toxoplasma gondii is an obligatory intracellular parasite, capable of infecting a large variety of intermediate hosts including humans. In the domiciliary environment, the infected final hosts (cats) spread the oocists by their excrements, which quickly reach maturity in the ground and become infectants. Therefore, toxoplasmosis is acquired by humans through
