Differentiation of Brucella ovis from Brucella abortus by gas-liquid chromatographic analysis of cellular fatty acids.
The cellular fatty acid composition of Brucella ovis and Brucella abortus strains was determined by gas-liquid chromatography. Both species were characterized by the presence of fatty acids 16:0, 17:0, 17:0 cyclopropane, 18:0, 18:1, and 19:0 cyclopropane; B. ovis also contained some 15:0. There were differences in the relative proportions of the fatty acids present, and it was possible to diffe...
متن کاملCanine Brucellosis: Brucella canis
Canine brucellosis, caused by Brucella canis, is an important cause of reproductive failure, particularly in kennels. This organism causes abortions, stillbirths, epididymitis, orchitis and sperm abnormalities in dogs. Although dogs that have been spayed or neutered do not have reproductive signs, they occasionally develop other conditions such as ocular disease and discospondylitis. B. canis c...
متن کاملCanine Brucellosis Caused by Brucella Canis
Etiology and Epidemiology Canine brucellosis is caused by Brucella canis (B. canis), a rough, small, gram-negative, intracellular bacterium. Other Brucella species, i.e., B. abortus, B. suis, have occasionally caused canine infections but they are not discussed here. The canine brucella was first recognized in 1966 as a cause of abortions and reproductive failures and it has since been recogniz...
متن کاملBrucella abortus siderophore 2,3-dihydroxybenzoic acid protects brucellae from killing by macrophages.
Addition of 2,3-dihydroxybenzoic acid, a siderophore produced by Brucella abortus, to macrophage cultures prevented intracellular killing of brucellae during the first 12 h after infection and increased the number of intracellular brucellae recovered at 48 h after infection. The protective effect could be demonstrated with inflammatory macrophages, interferon-gamma-activated macrophages and wit...
متن کاملRapid differentiation of bacterial meningitides by direct gas-liquid chromatography.
Rapid identification of Haemophilus influenzae and other bacillary meningitides was attempted by gas-liquid chromatography (GLC) of the metabolic by-products in broth cultures and in cerebrospinal fluid (CSF) samples obtained from experimental meningitis produced in New Zealand White male rabbits. These results were correlated with the GLC of CSF of meningitis patients. A major peak with retent...
