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...
متن کاملRegulation 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...
متن کاملKilling of Brucella abortus by bovine serum.
Studies of the serum bactericidal system in bovine brucellosis were undertaken to investigate the role of the humoral immune response in protection of cattle against the facultative intracellular parasite Brucella abortus. Fresh sera from normal control cattle, infected cattle, and cattle immunized with B. abortus cell envelopes were collected before treatment and during the course of immunizat...
متن کاملRecent advances in Brucella abortus vaccines
Brucella abortus vaccines play a central role in bovine brucellosis control/eradication programs and have been successfully used worldwide for decades. Strain 19 and RB51 are the approved B. abortus vaccines strains most commonly used to protect cattle against infection and abortion. However, due to some drawbacks shown by these vaccines much effort has been undertaken for the development of ne...
متن کاملPantothenic acid synthesis by smooth Brucella abortus.
The relationship between formation of exogenous alanine and the establishment of nonsmooth variants in originally smooth cultures of Brucella abortus strains has been clearly demonstrated (Goodlow et al., 1950). Furthermore, the addition of D-alanine to smooth cultures in synthetic medium (Gerhardt and Wilson, 1948) results in earlier establishment of nonsmooth cells (Goodlow et al., 1951). Sub...
متن کاملMultivalent Fusion DNA Vaccine against Brucella abortus
As an alternative brucellosis prevention method, we evaluated the immunogenicity induced by new multivalent DNA vaccines in BALB/c mice. We constructed the vaccines by fusion of BAB1_0273 and/or BAB1_0278 open reading frames (ORFs) from genomic island 3 (GI-3) and the Brucella abortus 2308 sodC gene with a link based on prolines and alanines (pV273-sod, pV278-sod, and pV273-278-sod, resp.). Res...
