Provedor de dados: 58
Autores: Silva,Rita de Cássia Figueira; Nascimento,Elmiro Rosendo do; Pereira,Virgínia Léo de Almeida; Barreto,Maria Lúcia; Nascimento,Maria da Graça Fichel do.
Newcastle disease is characterized by respiratory manifestations in association with nervous and/or digestive symptoms. Its prevention is done by vaccination with live attenuated (lentogenic strains) and/or killed vaccines. The lentogenic strains can lead to strong post-vaccination reaction, principally due to the presence of other pathogenic agents. Among them, Mycoplasma synoviae is worldwide important, mainly in Brazil. The dissemination of this agent in poultry flocks has been achieved due to difficulties in diagnosis and disease reproduction, virulence variations among different M.synoviae strains, and attribution of typical M.synoviae disease manifestation to other disease agents. This experimental study in SPF chicks (Gallus gallus), previously...

Two outbreaks of contagious agalactia by Mycoplasma agalactiae occurred in Paraíba State, Northeastern Region of Brazil are reported. The disease was characterized by mastitis, agalactia and polyarthritis in does and polyarthritis and conjunctivitis in kids and lambs. Fever and anorexia were also observed. Morbidy was from 26.1% to 100% in does, 36.5 to 100% in kids and 49% in lambs. In one farm 14.3% of the lactating goats and 6.4% of the kids died or were euthanized. In the other, 3.3% of the does, 36.5% of the kids and 22.9% of the lambs died and 84 affected goats were euthanized to control the disease. M. agalactiae was isolated from milk, joint exudates, nasal swabs and ear washings. The colonies were characteristic of Mycoplasma and the agent did not...

Rapid diagnosis of vesicular stomatitis virus in Ecuador by the use of polymerase chain reaction
Provedor de dados: 58
Autores: Sepúlveda,Lya Madureira; Malirat,Viviana; Bergmann,Ingrid E.; Mantilla,Anibal; Nascimento,Elmiro Rosendo do.
Vesicular Stomatitis (VS) is a viral disease that has a great impact in animal health, as infected animals present marked decrease in meat and milk production. Its presence is a limiting factor for international animal trade. Besides the damage in the livestock productivity, such disease assumes an important role in animal health programs since it is clinically indistinguishable from Foot-and-Mouth Disease. The diagnosis of the VS has been made, mainly, through Complement Fixation, ELISA and Virus Neutralization tests, assays that allow not only for viral detection but also for differentiation of the two serotypes described for Vesicular Stomatitis Virus (VSV): New Jersey (NJ) and Indiana (Ind). In this work, a molecular diagnostic approach, the polymerase...

Detection of Mycoplasma pulmonis in laboratory rats
Provedor de dados: 58
Autores: Barreto,Maria Lucia; Nascimento,Elmiro Rosendo do; Campos,Carlos Augusto de Martino; Nascimento,Maria da Graça Fichel do; Lignon,Gilberto Brasil; Lira,Marie Luce Flores; Silva,Ricardo G.
This work was conducted on rats in two premises located in Niterói and Rio de Janeiro, Brazil. One is classified as conventional controlled and the other, conventional. The objective of the present study was to detect the presence of Mycoplasma pulmonis in animals with symptoms of respiratory disease and low reproductive performance. In the conventional controlled premises, 16 rats of Wistar-Furth strain were necropsied while in the conventional premises necropsy was performed on 12 rats of Hooded Lister strain. The clinical samples of lungs, trachea, oropharynx, middle ear, uterus and ovaries were subjected to culturing while the sera were tested for antibody detection. From 28 rats, 57.14% (16/28) were culture positive for M. pulmonis, being 81.25%...

Autores: Simas,Vanessa Silva; Santos,Felipe Faccini dos; Gouvêa,Raquel; Aquino,Maria Helena Cosendey de; Abreu,Dayse Lima da Costa; Nascimento,Elmiro Rosendo do; Pereira,Virginia Léo de Almeida.
O objetivo deste trabalho foi comparar a análise individual (plano de duas classes) e a análise por lotes (plano de três classes), priorizado pelo plano amostragem oficial da ANVISA, na influência do pré-resfriamento de carcaças de frangos de corte na redução da contaminação por coliformes termotolerantes. Foram analisadas 240 carcaças de frangos de corte, sendo coletadas 120 amostras antes e 120 após a etapa de pré-resfriamento, para quantificação de coliformes termotolerantes pela técnica de contagem em placas. As médias das contagens obtidas das carcaças coletadas antes e após o pré-resfriamento foram diferentes, com uma redução média de 0,99log10 UFC g-1 de coliformes termotolerantes. Na interpretação dos resultados obtidos antes do pré-resfriamento...

Autores: Rocha,Flávio Soares da; Jesus,Vera Lúcia Teixeira de; Torres,Helenita Marques; Gomes,Marcos José Pereira; Figueiredo,Márcio José de; Nascimento,Elmiro Rosendo do; Ferreira,Teresinha; Aquino,Maria Helena Cosendey de.
Trinta e nove touros provenientes de propriedades de pecuária leiteira (n=9) e de pecuária de corte (n=30), situadas na região do Médio Paraíba, Rio de Janeiro (RJ), foram investigados para a presença de Campylobacter fetus e Tritrichomonas foetus. Para a pesquisa de Campylobacter, amostras de esmegma foram coletadas e submetidas à técnica de cultivo e isolamento e amostras de lavado prepucial ao teste de Imunofluorescência Direta (IFD). Para a pesquisa de Tritrichomonas, foi utilizada a técnica de exame direto a partir de lavado prepucial. Foi observada a presença de C. fetus em 14 amostras (35,9 %), por meio da IFD, e o isolamento de C. fetus, subespécie venerealis, foi obtido a partir de quatro amostras (10,3%). T. foetus não foi identificado nas...
