Ferreira,Cyntia Silva; Ladeira,Luiz Orlando; Leite,Cristiano Fantini; Fonseca,Flávio Guimarães da; Ribeiro,Erica Milena de CastroA gold nanoparticles functionalization experiment was conducted in a biotechnology summer course at UFOP as a model for the introduction of the laboratory practice in nanotechnology for postgraduate courses in the areas of chemistry and biotechnology. The gold nanorods were synthesized by the seed method and then, functionalized with anti-IL-6 antibodies using the reagents EDAC/NHS and polyethyleneimine (PEI). ...
Genotypic characterization of psittacid herpesvirus isolates from Brazil
Luppi,Marcela Miranda; Luiz,Ana Paula Moreira Franco; Coelho,Fabiana Magalhães; Ecco,Roselene; Fonseca,Flávio Guimarães da; Resende,MauricioAbstract Thirty-six isolates of psittacid herpesvirus (PsHV), obtained from 12 different species of psittacids in Brazil, were genotypically characterized by restriction fragment length polymorphism (RFLP) analysis and PCR amplification. RFLP analysis with the PstI enzyme revealed four distinct restriction patterns (A1, X, W and Y), of which only A1 (corresponding to PsHV-1) had previously been described. To st...

Trindade,Giliane de Souza; Fernandes,André Tavares da Silva; Costa,Galileu Barbosa; Figueiredo,Poliana de Oliveira; Abrahão,Jônatas SantosIntroduction Hantavirus infections have been described in several regions in Brazil through seroepidemiological studies. Usually, populations are associated with rural and wild environment mainly due to close contact to species of Sigmodontinae rodents, considered hantavirus reservoirs. Methods A retrospective serosurvey was conducted to access the hantavirus seroprevalence in people living in regions affected ...
Clinical signs, diagnosis, and case reports of Vaccinia virus infections
Silva,Daniela Carla Medeiros; Moreira-Silva,Eduardo Augusto dos Santos; Gomes,Juliana de Assis Silva; Fonseca,Flávio Guimarães daVaccinia virus is responsible for a zoonosis that usually affects cattle and human beings in Brazil. The initial clinical signs of the infection are focal red skin areas, fever, and general symptoms similar to those of a cold.
