Unusual Route of Transmission for Brucella abortus

Vertical transmission of Brucella abortus causes sterility in pregnant mice.

The mechanisms of abortion and sterility induced by bacterial infection are largely unknown. In the present study, we found that Brucella abortus, a causative agent of brucellosis and facultative intracellular pathogen, caused sterility in pregnant mice. We have recently established a mouse model for abortion induced by B. abortus infection and high rates of abortion are observed for bacterial ...

Brucella abortus endocarditis.

T HE purpose of this report is to describe the successful treatment of a case of bacterial endocarditis due to Brucella abortus. As far as I have been able to discover at the date of writing, no successfully treated case of this disease has been reported previously, with the exception of a case of mixed bacterial endocarditis presented in 1954 by Quinn and Brown.' A second case of treated Br. a...

Regulation of Brucella abortus catalase.

All aerobic organisms have mechanisms that protect against oxidative compounds. Catalase, peroxidase, superoxide dismutase, glutathione, and thioredoxin are widely distributed in many taxa and constitute elements of a nearly ubiquitous antioxidant metabolic strategy. Interestingly, the regulatory mechanisms that control these elements are rather different depending on the nature of the oxidativ...

Development of a Differential PCR Assay for Detection of Brucella abortus and Brucella melitensis: an Analytical Approach for Monitoring of Brucella spp. in Foods of Animal Origin

Background: Classical bacteriological detection of Brucella species from food, and environment is routinely carried out based on morphological and biochemical characteristics. However, for increasing specificity and sensitivity of species identification methods, development of a molecular assay is necessary that was main aim of this study. Methods: Panel of some reference strains belonging to ...
