Abstract:

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 an

There are several diseases caused by different organisms from the genus Clostridia, and most of these are preventable with a sound vaccination program. Many of these infections can progress very rapidly; animals that were healthy yesterday are simply found dead with no observed signs of sickness. In most cases treatment is difficult or impossible, therefore we rely on vaccination to prevent infection. The most co

Brucellosis is a constraint to livestock production in Moçambique. Reproductive failure due to brucellosis has been reported in the country and abortions occur in cattle, sheep and goats on many of the farms in Maputo Province of Moçambique. Brucellosis is an infectious disease affecting mainly sexually mature animals and is caused by organisms of the genus Brucella. Brucella abortus is the species that mainly affects cattle throughout the world, while Brucella melitensis affects mainly goats and sheep.

Abstract:

Vaccine Brucella abortus strain RB51, unlike the wild strain 2308 and another vaccine strain (strain 19) does not induce anti-O-chain antibodies. An efficacious vaccine strain that fails to produce an O-chain and thus a lack of an anti-O-chain humoral response greatly simplifies identification of vaccinated versus field strain infected animals. The three primary objectives of this research were the following: 1) to develop a serological assay to detect anti-RB51 antibodies in vaccinated elk (Cervus elaphus nelsoni), 2) to identify potential antigenic alterations in RB51 after vaccination of el

Abstract:

Brucellosis is a disease of socio-economic and zoonotic importance worldwide. In animals it is associated with the ingestion of feed that is contaminated with cyetic material from aborting herd-mates, while in humans it is associated with the consumption of unpasteurised milk and dairy products from infected animals. It may also be acquired from contact with infected material of animal origin by farmers, veterinarians, and abattoir and laboratory workers. Brucellosis was first reported in South Africa in the late nineteenth century. It is still present in the country today, with reporte

Abstract:

Conventional subunit vaccine regimes can be modified in order to stimulate strong immune responses resulting in memory cell formation. An adjuvant system that has gained increased attention in recent years is the use of particulate antigen delivery. Particulate systems have a number of advantages over conventional approaches since they are believed to be taken up preferentially by dendritic cells (DC) where they prolong the release of antigen resulting in enhanced T cell stimulation. Furthermore, they offer a versatile system that allows for targeted delivery of antigen and adjuvant to the sam

Abstract:

Para dar suporte à implementação do Programa Nacional de Controle e Erradicação da Brucelose e Tuberculose Bovina no Estado do Rio Grande do Sul, foi realizado um estudo para caracterizar a situação epidemiológica da brucelose. Assim, o Estado foi dividido em sete regiões. Em cada região foram amostradas aleatoriamente cerca de 300 propriedades, e dentro dessas foi escolhido de forma aleatória um número pré-estabelecido de animais, dos quais foi obtida uma amostra de sangue. No total foram amostrados 16.072 animais, provenientes de 1.957 propriedades. Em cada propriedade amostrada foi aplicado

Abstract:

Weaning is defined as the physical separation of the cow-calf pair and the end of milk feeding. Natural weaning occurs between 7 and 14 months and is a gradual process. However, domestic weaning occurs between 6 and 8 months and occurs rapidly. Calves that are abruptly separated from their dam respond with increased vocalization and walking, and decreased eating and resting. The psychological stress the calf undergoes during weaning causes elevated glucocorticoid and catecholamine hormone concentrations that may predispose to increased morbidity and/or mortality from infectious diseases su

Abstract:

A Leucose Enzoótica dos Bovinos (LEB) é uma enfermidade neoplásica, infectocontagiosa, pluri-sintomática, de evolução crônica, que compromete os órgãos linfopoiéticos e está associada ao desenvolvimento de linfocitose persistente (LP) e linfossarcoma. Acarreta diminuição na produção, quer por seus efeitos danosos diretos, quer pelos indiretos. No entanto, seu efeito na função e na quantidade das diferentes subpopulações de linfócitos, assim como seu papel no estabelecimento de outras doenças oportunistas, ainda não está claro.

Abstract:

Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>Vaccines with antigenic markers also known as differential vaccines have been largely used for control and prevention of bovine herpesvirus 1 (BoHV-1) infection. With this purpose, a Brazilian BoHV-1 isolate (SV56/90) was submitted to deletion of the glycoprotein E (gE) gene for a potential use in vaccines. BoHV-1 gE gene deletion was performed by homologous recombination, being the gE gene replaced by the green fluorescent protein (GFP) gene for selection.
