Brucella spp. is a worldwide zoonotic pathogen. Infection by Brucella canis in dogs is endemic in the Southern USA and in Central and South America, but it appears sporadically in other parts of the world, including Europe. Tissue samples from a dog with chronic prostatitis, discospondylitis and locomotor problems were subjected to clinical and laboratory examinations. B. canis was detected by ...
Lipopolysaccharides (LPS) were extracted from rough strains of Brucella abortus and Brucella melitensis and from strains of the naturally occurring rough species Brucella ovis and Brucella canis. Brucella rough lipopolysaccharides (R-LPS) were readily distinguished from Brucella smooth lipopolysaccharides (S-LPS) and enterobacterial R-LPS, by their chemical, physical, and serological characteri...
An imported dog was confirmed to be positive with canine brucellosis in Sweden in 2010. The whole genome of Brucella canis SVA10 was subjected to phage analysis (WGS-PA) and was assigned to the Asian B. canis cluster. Further analysis indicated that the genome of B. canis SVA10 is smaller compared to genomes of the same species. A 35,781 bp genomic island (GI) was found to be absent in strain S...
The gram-negative organism causing abortion in dogs was examined in parallel with cultures representative of the Brucella species and with Bordetella bronchiseptica. The organism fits into the genus Brucella and most closely resembles B. suis on the basis of its growth characteristics. It is of rough colonial morphology and is agglutinated by antisera prepared against rough Brucella. In mouse t...
The less mucoid strain of Brucella canis or M- strain is used for the serologic diagnosis of canine brucellosis. While this strain is avirulent in dogs, we report the case of clinical brucellosis that developed in a laboratory worker a few days after handling live M- cells for antigen production.
Two new primer sets of a 766- and a 344-bp fragment were introduced into the conventional Bruce-ladder PCR assay. This novel multiplex PCR assay rapidly and concisely discriminates Brucella canis and Brucella microti from Brucella suis strains and also may differentiate all of the 10 Brucella species.
An outbreak of canine brucellosis in Sweden was confirmed by the National Veterinary Institute (SVA) in August 2013. The whole genome of the causative agent was sequenced, assembled, and analyzed.
A rough-specific antigen extracted from the rough species Brucella ovis and lipopolysaccharide extracted from smooth Brucella abortus demonstrated equivalent levels of activity in tests for mouse lethality and limulus lysate clotting activity. Acetone-extracted whole cells of B. ovis and of B. canis and of a rough mutant of B; abortus had the same toxicity for mice, but it was not possible to e...
The cellular fatty acid composition of Brucella canis and Brucella suis was determined by gas-liquid chromatography. The presence of relatively large amounts of a 19-carbon cyclopropane fatty acid in B. suis was a major distinguishing feature between these organisms. The gas-liquid chromatography test for cellular fatty acids provides an additional criterion for the distinction of antigenically...
In this study, rapid slide agglutination test (RSAT) antigens were produced by using homologous (Brucella canis RM6/66 and a wild B. canis) and heterologous brucella strains (B. abortus 45/20 and B. melitensis B115) for a quick, practical and economic diagnosis of B. canis infection in dogs and humans. All the test strains were grown in three different culture media, namely, trypton liquid medi...
