A UNIFEOB mantém uma política de pesquisa que tem como objetivo orientar as ações desenvolvidas nesse campo do conhecimento. As pesquisas têm alicerce em princípios e critérios de produção de conhecimento científico e tecnológico, seguindo normas éticas de pesquisa em seres humanos e animais e dissociada do ensino e da extensão. As atividades convergem com as diretrizes nacionais, visando o desenvolvimento sustentável social, econômico e ambiental.

Item Pneumonia enzoótica suína: características gerais e sua importância na suinocultura(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) MIRANDA, Juliana C.; SILVA, Marcos Donizete da; CARVALHO, Ana Flávia deMycoplasma hyopneumoniae is the etiological agent of Swine Enzootic Pneumonia, characterized by dyspnea, dry cough, anorexia, growth retardation, lethargy, and fever, causing great economic losses for the swine industry. The diagnosis by ELISA (Enzyme Linked Immunosorbent Assay) has high specificity and sensitivity in the detection of M. hyopneumoniae. Treatment is based on the administration of high doses of antibiotics. Vaccination helps to decrease the clinical presentation of the disease, and prophylaxis is the best tool to fight the disease.Item Criptococose: principais aspectos e sua importância na saúde pública(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) MIRANDA, Juliane C.; FALCÃO, Sara Carolina Fernandez; SILVA, Marcos Donizete da; CARVALHO, Ana Flávia deCryptococcosis is a systemic fungal disease caused by Cryptococcus neoformans, present in the environment and mainly in pigeon feces. Contamination occurs via aerosol, and it spreads through the body via hematogen. Diagnosis can be made by culture of the fungus and serological tests. Treatment is with antifungal drugs and the prognosis varies from good to bad. This type of infection is common in AIDS patients.Item Caracterização do placentônio em búfalos(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) SILVA, Marcos Donizete da; LUCIANO, Adriano Pedreira; MIRANDA, Juliane Cristina; PEREIRA, Flávia Thomaz Verechia; CARVALHO, Ana Flávia deBuffaloes are very important animals in the context of contemporary livestock, as they are excellent suppliers of milk, meat and workforce, in addition to being extremely rustic, with this, countless studies on these animals, so peculiar, are developed with the intention of better understand their physiology and develop new production and reproduction techniques to advance their creation.Item Anormalidades na placenta bovina de clones e interferência no desenvolvimento embrionário fetal(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) LUCIANO, Adriano Pedreira; SILVA, Marcos Donizete da; MIGLINO, Maria Angélica; CARVALHO, Ana Flávia deBovines are very important animals for the population of today, as they are an excellent source of protein, with this, several researches are carried out in order to improve the quality and to achieve greater productivity of a herd. New techniques for production and reproduction are important for the advancement of the bovine cut which is growing more and more. An example of this is the cloning of animals of high genetic value, through the transfer of somatic nucleus (NT). This technique causes high loss of fetuses and mortality at birth due to a syndrome, related to the development of the placenta.Item Análise morfológica de embriões ovinos produzidos em laboratório a partir de oócitos aspirados de doadoras multíparas, primíparas e pré - púberes da raça Santa Inês(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) MARTINS, João Flávio Panattoni; SANTOS, Thainá de Oliveira; SILVA, Marcos Donizete da; SOUZA, Bruna Manzer de; OLIVEIRA, Priscila C. de; ROSAS FILHO, Adauto de Carvalho; ABREU, Rogério Navarro de; FIGUEIREDO, Cristiane LeiteThis work aimed to analyze the morphology of embryos at seven days of development, produced in the laboratory from oocytes aspirated from three different classes of donors of the Santa Inês race (multiparous, primiparous and prepubertal). The analyzed embryos had a discoid shape and were delimited by the pellucid zone (ZP). In the morula and initial blastocyst stages, the ZP measured from 5 to 10 μm in thickness, revealing to be thinner in the expanded blastocyst phase. In general, the structure and ultrastructure of Santa Inês sheep embryos, originating from in vitro fertilization (IVF) and evaluated in this study, corroborate many of the observations by Colarco and Mclaren (1976), Ferrer et al. (1995) and Coccero et al. (2002). The most striking aspect was the intense uniform distribution of lipid inclusions in the cytoplasm of the blastomeres, both in the internal cell mass and in the trophoblastic cells, regardless of the origin of the oocyte, suggesting that the morphology seems to be conditioned mainly to the culture system employed, which seems to favor the accumulation of intracellular lipids.Item Estudo de embriões ovinos em laboratório a partir de doadoras juvenis da raça Santa Inês submetidas a estimulação ovariana(Centro Universitário da Fundação de Ensino Octávio Bastos, 2010-05-30) MARTINS, João Flávio Panattoni; SANTOS, Thainá de Oliveira; SILVA, Marcos Donizete da; SOUZA, Bruna Nanzer; OLIVEIRA, Priscila Carvalho de; FIGUEIREDO, Cristiane Leite; ROSAS FILHO, Adauto de Carvalho; ABREU, Rogério Navarro deThis study aimed to verify the superovulatory response of juvenile Santa Inês sheep and to evaluate the viability of oocytes obtained for in vitro production (IVP) of embryos. Eight females aged between 6 and 8 weeks were selected, distributed in 2 homogeneous groups of 04 animals. The females in Group 1 (G1) were submitted to exogenous ovarian stimulation and in Group 2 (G2) the females were aspirated free of hormonal treatment. From a total of 309 retrieved oocytes (G1 = 187 and G2 = 122), cleavage rates of 49.2% and 40.2% were obtained for G1 (n = 92) and G2 (n = 45) respectively, and 18.72% and 17.96% of viable embryo development in D7 (G1 = 35 and G2 = 19). Although the results suggest a better efficiency in the recovery of oocytes and cleavage rate in G1, the rates of obtaining viable embryos in D7 did not differ numerically between the two groups. Our results suggest that, although there was great variation in the amount of oocytes obtained and the production of embryos among animals, regardless of treatment, the production of embryos by in vitro fertilization (IVF) from juvenile females treated or not with exogenous hormones proved to be viable, even with good efficiency of the hormonal protocol used for females of the Santa Inês breed.
