Brucella canis is a Gram-negative bacterium in the family Brucellaceae that causes brucellosis in dogs and other canids. It is a non-motile short-rod or coccus-shaped organism, and is oxidase, catalase, and urease positive. [1] B. canis causes infertility in both male and female dogs. It can also cause inflammation in the eyes.
Brucellosis [4] is a zoonosis caused by ingestion of unpasteurized milk from infected animals, or close contact with their secretions. [5] It is also known as undulant fever, Malta fever, and Mediterranean fever.
Sir David Bruce isolated B. melitensis from British soldiers who died from Malta fever in Malta.After exposure to Brucella, humans generally have a two- to four-week latency period before exhibiting symptoms, which include acute undulating fever (>90% of all cases), headache, arthralgia (>50%), night sweats, fatigue, and anorexia.

Breed, lack of water, exercise, and high ambient temperature predispose dogs to heat stroke. Signs include vomiting, diarrhea, collapse, difficulty breathing, and body temperature approaching 42 °C to 43 °C. Treatment includes cooling the dogs with wet towels and fans, intravenous fluid therapy, and other supportive care. [171]
Dogs will typically recover from kennel cough within a few weeks. However, secondary infections could lead to complications that could do more harm than the disease itself. [ 2 ] Several opportunistic invaders have been recovered from the respiratory tracts of dogs with kennel cough, including Streptococcus , Pasteurella , Pseudomonas , and ...
Brucella melitensis is a Gram-negative coccobacillus bacterium from the Brucellaceae family. The bacterium causes ovine brucellosis , along with Brucella ovis . Humans can become infected if they have contact with an infected animal or its byproducts.
The most notable of these are Bordetella bronchiseptica, one of the causes of kennel cough, Leptospira sp, which cause leptospirosis, [3] [4] and Brucella canis, cause of brucellosis in dogs. There are also common tick-borne bacterial diseases, including Lyme disease , ehrlichiosis , and Rocky Mountain spotted fever .
Brucella abortus is a Gram-negative bacterium in the family Brucellaceae and is one of the causative agents of brucellosis. The rod-shaped pathogen is classified under the domain Bacteria. [ 1 ] The prokaryotic B. abortus is non-spore-forming, non-motile and aerobic.
