Abstract:

Bovine tuberculosis is in the UK a persistent disease, affecting cattle and badgers. The latter is suspected to be a reservoir for Mycobacterium bovis but the transmission between badgers and cattle remains unclear. Mycobacteria have been shown to survive ingestion by protozoa and some even multiplied inside amoebas. The aim of this study was to investigate some interactions of Acanthamoeba castellanii and Tetrahymena pyriformis with M bovis. Firstly, the long term survival of the bacilli in protozoa was monitored. Secondly, it was investigated whether bacilli internalized in protozoa cysts ar

Abstract:

Mycobacterium bovis and Mycobacterium tuberculosis are the causative agents of bovine and human tuberculosis, respectively. The standard diagnosis is based on the isolation and identification of bacterial colonies through biochemical methods. These methodologies in addition to being costly, require an environment with high level of biosecurity and a great time of cultivation and tests to obtain the results. The molecular tests based on the principles of real-time PCR using the fluorophore Eva Green were efficient in the identification of M. bovis and M. tuberculosis. In addition, analyses were

Abstract:

In Great Britain a recent independent scientific review into bovine tuberculosis concluded that the best prospect for control of TB in the national herd is to develop a vaccine. The secreted antigens of the Mycobacterium tuberculosis complex have received much interest as possible vaccine candidates due to their ability to confer protection against tuberculosis in small animal models. The recent discovery that some of these mycobacterial antigens are glycosylated, a modification ubiquitous in eukaryotic proteins, may provide some novel insights into the properties of these antigens.

Bovine tuberculosis, caused by Mycobacterium bovis, infects approximately 50 million cattle worldwide and is diagnosed by the tuberculin skin test (TST).

Sterile filtered PPD tuberculin (SF-PPD) resolved into approximately 200 discrete spots using two-dimensional PAGE.

An investigation was carried out to determine the presence and persistence of Mycobacterium bovis in the environment. Soil samples were taken in April 2000 from a farm in Ireland which had undergone a bovine tuberculosis outbreak some four months prior. Total community DNA was extracted from these samples and PCR carried out targeted to two genes specific for the Mycobacterium tuberculosis complex; mpb64 and mpb70. These genes were detected in soil samples taken from entrances to two badger sets and in soil from two sites where the infected cattle grazed. Further analysis of DNA using oligonuc

Therefore, a novel TB therapy that limits the development of resistance has become necessary in an attempt to effectively control TB. The anti-TB drugs directly target mycobacterial enzymes, and potentiate the development of this resistance, and have therefore provided the rationale for this study.

Despite benefiting from a successful test-and-slaughter programme, initiated in the late 1960s, which has reduced the prevalence to 0.05% (reactors in tuberculinated cattle) in 2006, there is little known about the epidemiology of <i>M. bovis</i> in Iran.

Abstract:

La tuberculose bovine est une maladie infectieuse contagieuse causée par Mycobacterium bovis. Cette maladie touche les bovins et de nombreuses espèces de mammifères domestiques et sauvages, ainsi que l’homme. La circulation de la bactérie dans des systèmes multi-hôtes variés favorise l’entretien de la maladie et la contamination des bovins vivant à proximité des animaux sauvages infectés. En marge de la transmission directe de M. bovis par voie respiratoire, la transmission indirecte aux bovins, liée à l’inhalation ou à l’ingestion de matrices environnementales contaminées par un animal infect

Abstract:

A resistência térmica dos microrganismos sofre influência, entre outros fatores, das características do agente e das características do substrato, como o teor de gordura. Um dos objetivos da pasteurização do creme é a eliminação dos patógenos eventualmente presentes no leite. Entretanto, não há padrão de tempo e temperatura de pasteurização para este produto na legislação. O Mycobacterium bovis é considerado o patógeno não formador de esporo de maior resistência térmica que pode normalmente ser transmitido pelo leite. Assim, este trabalho se propõe a avaliar a inativação de Mycobacterium bovis

Abstract:

A tuberculose é considerada um problema emergente de saúde pública. Este estudo tem como objetivo avaliar a associação da patogenicidade/virulência e propriedades imunomoduladoras de isolados clínicos de Mbv (cepas B2 e MP287/03) e Mtb (cepa Beijing 1471), e da cepa de Mtb H37Rv, como referência de virulência. Os isolados, MP287/03 e Beijing 1471, apresentaram maior virulência em relação às demais cepas, levando os camundongos à morte ainda na fase aguda de infecção. Foi verificada baixa produção de mediadores pró-inflamatórios nos animais infectados com o isolado MP287/03, enquanto nos infect

Abstract:

Streptomyces coelicolor and Mycobacterium bovis are high G+C gram-positive members of the phylum Actinobacteria. M. bovis is a member of the M. tuberculosis species complex and M. bovis, BCG is the attenuated vaccine strain used as a model organism as it can be manipulated in containment Category 2 laboratories. When cells are exposed to different environments/stresses they need to adapt their physiology and biochemistry for their effective survival. A key mechanism of adaptation is the ability to quickly alter the molecular composition of the cell through the regulation of gene expression bot

Abstract:

Studying the dynamics of pathogen transmission within wildlife populations presents an array of challenges. Where populations are socially structured, this can influence parasite transmission, impacting on the effectiveness of disease management strategies. In this thesis, I focus on a well-studied social mammal, the European badger (Meles meles) which is a key wildlife reservoir of a disease of economic importance; bovine TB (caused by infection with Mycobacterium bovis). The social structuring, characteristic of high density badger populations, is of well-established importance in the transm

Abstract:

Bovine TB in cattle is a major economic problem in the UK, costing the government approximately £100m a year. Badgers are a wildlife host of the infection that causes bovine TB, and there is strong evidence that they transmit the infection to cattle. Understanding the ecology and epidemiology of infected badger populations is therefore crucial for implementing disease management strategies relating to badgers. Genetic and phenotypic data of badgers captured during a large-scale field trial of repeated, widespread badger culls were used to assess the importance of parental roles on the impacts

Abstract:

Depuis les annees 20, mycobacterium bovis bcg (bacille calmette-guerin) est le vaccin vivant utilise pour la protection antituberculeuse. Pourtant, l'existence d'une variabilite, de 0 a 80%, de la protection antituberculeuse induite par ce vaccin demontre clairement une derive des souches de bcg actuellement utilisees. Un composant majeur des parois mycobacteriennes, le lipoarabinomannane ou lam est suppose, aujourd'hui, etre un facteur determinant dans l'infection et la survie intramacrophagique des mycobacteries, etapes necessaire a la mise en place d'une immunite protectrice par le bcg.
