Heterogeneity of Brucella abortus lipopolysaccharides
Research in Microbiology, 1995This work demonstrates that Brucella lipopolysaccharide (LPS) preparations are a family of related molecules which display heterogeneity not only at the level of the O polysaccharide, but also at the core oligosaccharide and the lipid A. Sodium dodecyl sulphate/polyacrylamide gel electrophoresis and Western blotting showed that LPS from Brucella ...

The alanine racemase of Brucella abortus
Archives of Biochemistry and Biophysics, 1954Wood and Gunsalus (1) have isolated, resolved, and partially purified an enzyme from Streptococcus jaecalis which racemizes alanine and which is specifically activated by pyridoxal phosphate. This enzyme is widely distributed among bacteria but absent in yeast, molds, and animal tissues.

BRUCELLA ABORTUS INFECTION IN THE BULL
Australian Veterinary Journal, 1976Observations on 2 bulls from a brucella-infected property are reported. Bull 1 gave serological reactions to Br. abortus in both the SAT and CFT from day 0 to day 141. Br. abortus was not recovered from semen and the bull remained clinically normal. The serological status of bull 2 changed from negative to positive to negative over a 203 day period and

Studies on Infection with Brucella Abortus Variants
The Journal of Immunology, 1948Summary Infection of mice, rabbits, and guinea pigs with a number of variants of Brucella abortus (clones of S, I, R, M, etc. isolated from virulent and avirulent cultures) was accompanied by strikingly different agglutinin production among the three host-species after inoculation of identical antigens.

Laboratory Maintenance of Brucella abortus
Current Protocols in Microbiology, 2006AbstractThis unit provides protocols for growth of Brucella abortus on solid or in liquid media and for long‐term storage of laboratory stocks. Two issues affecting the culture and storage of isolates of this slow‐growing bacterium are emphasized: contamination of cultures and outgrowth of attenuated variants lacking a complete lipopolysaccharide ...

Immunochemical studies on brucella abortus lipopolysaccharides
Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1983The antigenic-toxic complex of B. abortus isolated in the phenol phase of phenol/water system, is a lipopolysaccharide (LPS)-protein macromolecule. The specific side chain was isolated from this complex by means of pronase treatment and mild HCl cleavage, followed by fractionation on Sephadex.

Journal of the American Medical Association, 1929
Brucella abortus is a short, gram-negative bacillus, first described by Bang in 1897. Evans 1 was the first to point out its close similarity to the organism described by Bruce in 1893 as Micrococcus melitensis . The organisms are indistinguishable morphologically, culturally or even by ordinary agglutination tests, but they can be distinguished by ...

Summary 1. An organism isolated in pure culture from a withers abscess in a horse proved to be indistinguishable microscopically, culturally and serologically from Br. abortus . 2. The blood serum and abscess fluid from the horse under observation agglutinated various Br. abortus antigens up to, and including, 1 in 500.
