The behavior and effects of Brucella abortus rough strain RB51 in mice and cattle

Buhrman, Dianne L. 21 November 2012 (has links)
Brucella abortus st. RB51 is a rough mutant of smooth st. 2308 devoid of O-side chain and resistant to rifampin. The purpose of this investigation was to study the behavior and effects of viable st. RB51 organisms in inoculated mice and cattle and to further substantiate the lack of O-side chain antigens in this strain. A single injection of live st. RB51 persisted in BALB/C mice up to 28 days. A secondary exposure was cleared in 7-21 days. One or 2 injections of st. RB51 did not induce detectable titers of anti-O-side chain antibodies, although antibody titers to st. RB51 whole cell and cytoplasmic antigens were detected. Mice infected with st. RB51 alone or followed by infection with st. 2308, demonstrated a very strong reaction to a 14-18 Kd antigen which was believed to be the core of the LPS complex. When st. RB51 was administered after injection of st. 2308 the response to the core determinants were inhibited. One vaccination with st. RB51 was able to significantly protect mice against challenge with st. 2308 at one and four weeks post challenge. Two st. RB51 vaccinations were able to protect mice as well as one vaccination at one week post challenge but protection increased by four weeks post challenge. Strain RB5l was able to survive in cattle a for at least twenty-two days. The organism remained stable, rifampin resistant, and may have induced minor amounts of transient anti-O-side chain antibodies in some cows late in the experiments. / Master of Science

Soroprevalência da brucelose bovina em frigoríficos com diferentes níveis de serviço de inspeção no estado de São Paulo /

Mioni, Mateus de Souza Ribeiro. January 2015 (has links)
Orientador: Jane Megid / Banca: Luis Antonio Mathias / Banca: José Paes de Almeida Nogueira Pinto / Resumo: Foi estimada a prevalência estadual da brucelose bovina em abatedouros nos diferentes níveis de inspeção sanitária no Estado de São Paulo após a implantação do Programa Nacional de Controle e Erradicação da Brucelose e Tuberculose (PNCEBT), instituído em 2001. Para tanto, foram amostrados 1.490 bovinos em nove frigoríficos distribuídos em diferentes regiões do estado, dos quais três com inspeção federal (SIF), três com inspeção estadual (SISP) e três com inspeção municipal (SIM). Os soros foram analisados pelas provas do antígeno acidificado tamponado (AAT), e os reagentes foram confirmados pela reação de fixação de complemento (RFC). As prevalências obtidas por meio da RFC e seus respectivos intervalos de confiança, nos diferentes serviços de fiscalização, foram 0,40% [0,00% - 0,95%] (SIF), 2,00% [0,77% - 3,23%] (SISP) e 4,29% [2,67% - 6,48%] IC95% (SIM) e no estado foi estimada em 2,21% [1,47% - 2,96%]. Com os resultados obtidos, foi possível discutir a situação da brucelose bovina no Estado de São Paulo bem como o risco à saúde a que os trabalhadores de abatedouros estão expostos e a diferença entre os sistemas de inspeção vigentes no país. Concluiu-se que a soroprevalência da brucelose bovina no Estado de São Paulo permaneceu estável. Sugere-se que a adoção de novas medidas para complementar o PNCEBT poderiam acelerar o controle e a posterior erradicação da enfermidade; e que o aumento da fiscalização nos abatedouros de inspeção estadual e municipal acrescido de vigilância ativa nesses pontos poderia auxiliar no combate à doença / Abstract: This study estimated the prevalence of bovine brucellosis in state of São Paulo as well as the prevalence in slaughterhouses with different levels of sanitary inspection in the same state after the implementation of the National Program for the Control and Eradication of Brucellosis and Tuberculosis (PNCEBT) established in 2001. Were sampled 1,490 animals in nine slaughterhouses distributed in different regions of the state, three with federal inspection (FI), three with state inspection (SI), and three with municipal inspection (MI). Sera were analyzed by Rose Bengal Test (RBT) and reaction of complement fixation test (CFT). The prevalence obtained through CFT in different inspection services were, 0.40% [0.00% - 0.95%] (FI), 2.00% [0.77% - 3.23%] (SI) e 4.29% [2.67% - 6.48%] IC95% (MI) and the state prevalence was estimated at 2.21% [1.47% - 2.96%]. With the results obtained, it was possible to evaluate the situation of the bovine brucellosis in state of São Paulo as well as the risk to public health that workers are exposed in slaughterhouses and the difference between the current inspection systems in the country . It was concluded that the seroprevalence of brucellosis in the state of São Paulo remained stable, and the adoption of new measures to enhance the PNCEBT could acelerate the control and eventual eradication of the disease. In addition, we also conclude that the increased surveillance in slaughterhouses with state and municipal inspection attached to surveillance at these points could assist in combating of disease / Mestre

Estudo da situação epidemiológica da brucelose e tuberculose bovina em propriedades fornecedoras de leite para o programa "Laticínio Escola" do município de Botucatu-SP /

Martinho, Anna Paula Vitirito. January 2014 (has links)
Orientador: Antonio Carlos Paes / Coorientador: Jane Megid / Banca: Hélio Langoni / Banca: Rogério Giuffrida / Resumo: A brucelose e tuberculose são enfermidades infectocontagiosas de evolução crônica, de caráter zoonótico, que representam grandes prejuízos econômicos à bovinocultura leiteira e saúde pública. Os objetivos deste trabalho foram: estudar a situação epidemiológica destas enfermidades nas propriedades fornecedoras de leite para o Programa Municipal de Botucatu intitulado "Laticínio Escola"; determinar o grau de conhecimento dos pequenos produtores acerca destas doenças por meio de um questionário elaborado para essa finalidade. Ao final do questionário os produtores receberam instruções técnicas sobre os temas abordados e foi realizado um trabalho social de conscientização sobre a importância zoonótica e sanitária. O estudo foi conduzido em 22 pequenas propriedades leiteiras do município de Botucatu-SP, que fornecem leite para creches e escolas municipais. Os testes realizados foram os preconizados pelo Programa Nacional de Controle e Erradicação de Brucelose e Tuberculose (PNCEBT), que são sorológicos para brucelose e imunoalérgico para tuberculose. Os animais reagentes a ambos os testes foram retirados da propriedade, levados ao Hospital Veterinário da FMVZ/UNESP, campus de Botucatu, para realização de exame necroscópico. O total de animais testados para Tuberculose foi 736, e para Brucelose 512. Encontrou-se pelo menos um bovino positivo para tuberculose em 13,6% (3/22) das propriedades, e para brucelose em 31,8% (7/22). A prevalência das enfermidades observada foi de 0,8% (6/736) e 2,3% (12/512) para tuberculose e brucelose, respectivamente. Os dados deste estudo foram semelhantes aos encontrados em trabalhos regionais da literatura nacional. Portanto, na microrregião de Botucatu-SP, estas enfermidades ainda representam grande relevância socioeconômica, sanitária e de saúde pública / Abstract: Brucellosis and tuberculosis are chronic infectious diseases and considered as zoonosis, which represent large economic losses to dairy cattle and public health. Our objectives were to study the epidemiological situation of these diseases in the properties that supply milk to the Municipal Program of Botucatu entitled "Dairy School"; determine the degree of knowledge of small farmers about these diseases through a questionnaire prepared for this purpose. At the end of the questionnaire the producers received technical instruction on the topics and we performed a social work awareness of zoonotic importance and health. The study was conducted in 22 small dairy farms of Botucatu-SP, which provide milk for kindergartens and public schools. The tests performed were those recommended by the National Program for Control and Eradication of Brucellosis and Tuberculosis (PNCEBT), which are serologic for brucellosis and tuberculosis imunoalergic. Reagents animals to both tests were removed from the property, taken to the Veterinary Hospital of FMVZ/UNESP, Botucatu, to perform necropsies. The total number of animals tested for tuberculosis was 736, and for brucellosis 512. It has been found Brucellosis at least one positive for tuberculosis in 13.6% (3/22) of properties, for brucellosis in 31.8% (7/22). The prevalence of disease observed was 0.8% (6/736) and 2.3% (12/512) for tuberculosis and brucellosis, respectively.
