The Brucellaceae are a family of the Gram-negative Rhizobiales. They are named after Sir David Bruce, a Scottish microbiologist. They are aerobic chemoorganotrophes. [3] The family comprises pathogen and soil bacteria [3]

Rhizobiales order of bacteria

The Rhizobiales are an order of Gram-negative Alphaproteobacteria.

Scotland Country in Europe, part of the United Kingdom

Scotland is a country that is part of the United Kingdom. Sharing a border with England to the southeast, Scotland is otherwise surrounded by the Atlantic Ocean to the north and west, by the North Sea to the northeast and by the Irish Sea to the south. In addition to the mainland, situated on the northern third of the island of Great Britain, Scotland has over 790 islands, including the Northern Isles and the Hebrides.

Microbiologist person who investigates the characteristics of microscopic organisms

A microbiologist is a scientist who studies microscopic life forms and processes. This includes study of the growth, interactions and characteristics of microscopic organisms such as bacteria, algae, fungi, and some types of parasites and their vectors. Most microbiologists work in offices and/or research facilities, both in private biotechnology companies as well as in academia. Most microbiologists specialize in a given topic within microbiology such as bacteriology, parasitology, virology, or immunology.

<i>Brucella</i> genus of bacteria

Brucella is a genus of Gram-negative bacteria, named after David Bruce (1855–1931). They are small, nonencapsulated, nonmotile, facultatively intracellular coccobacilli.

Brucellosis Human disease

Brucellosis is a highly contagious zoonosis caused by ingestion of unpasteurized milk or undercooked meat from infected animals, or close contact with their secretions. It is also known as undulant fever, Malta fever, and Mediterranean fever.

Hepatosplenomegaly is the simultaneous enlargement of both the liver (hepatomegaly) and the spleen (splenomegaly). Hepatosplenomegaly can occur as the result of acute viral hepatitis, infectious mononucleosis, and histoplasmosis or it can be the sign of a serious and life-threatening lysosomal storage disease. Systemic venous hypertension can also increase the risk for developing hepatosplenomegaly, which may be seen in those patients with right-sided heart failure.

David Bruce (microbiologist) British pathologist

Major-General Sir David Bruce was a Scottish pathologist and microbiologist who investigated Malta fever and African trypanosomiasis. He discovered a protozoan parasite transmitted by insects, later named Trypanosoma brucei after him. Working in the Army Medical Service and the Royal Army Medical Corps, his major scientific collaborator was his microbiologist wife Mary Elizabeth Bruce, with whom he published more than thirty technical papers.

<i>Brucella melitensis</i> species of bacterium

Brucella melitensis is a Gram-negative coccobacillus bacterium from the Brucellaceae family. The bacterium causes ovine brucellosis, along with Brucella ovis. It can infect sheep, cattle, and sometimes humans, and it can be transmitted by the stable fly. It is zoonotic, unlike B. ovis, causing Malta fever or localized brucellosis in humans.

Swine brucellosis species of bacterium

Swine brucellosis is a zoonosis affecting pigs, caused by the bacterium Brucella suis. The disease typically causes chronic inflammatory lesions in the reproductive organs of susceptible animals or orchitis, and may even affect joints and other organs. The most common symptom is abortion in pregnant susceptible sows at any stage of gestation. Other manifestations are temporary or permanent sterility, lameness, posterior paralysis, spondylitis, and abscess formation. It is transmitted mainly by ingestion of infected tissues or fluids, semen during breeding, and suckling infected animals.

Brucella abortus is a Gram-negative proteobacterium in the family Brucellaceae and is one of the causative agents of brucellosis. The rod-shaped pathogen is classified under the domain Bacteria. The prokaryotic B. abortus is non-spore-forming, nonmotile and aerobic.

Brucella canis is a Gram-negative proteobacterium in the family Brucellaceae that causes brucellosis in dogs and other canids. B. canis is rod-shaped or a coccus, and is oxidase, catalase, and urease positive. The species was firstly described in United States in 1966 where mass abortions of beagles were documented. The disease is characterized by epididymitis and orchitis in male dogs, endometritis, placentitis, and abortions in females, and often presents as infertility in both sexes. Other symptoms such as inflammation in the eyes and axial and appendicular skeleton; lymphadenopathy and splenomegaly, are less common. Humans can be also infected, but occurrences are rare.

Brucella agar is a form of agar used to culture species of Brucella and Campylobacter jejuni

Brucella ovis is a Gram-negative coccobacillus from the Brucellaceae family. Along with Brucella melitensis, it is responsible for causing ovine brucellosis, which is a notifiable disease. B. ovis can be transmitted by the stable fly. Infection causes severe inflammation of the epididymis, particularly the tail.

Brucella pinnipedialis is a species of bacteria. It causes infections and related diseases primarily in pinnipeds and cetaceans.

Brucella microti is a species of bacteria first isolated from the common vole, Microtus arvalis. Its genome has been sequenced. It is Gram-negative, non-motile, non-spore-forming, and coccoid, with the type strain CCM 4915T. It is pathogenic.

Crabtreella is a genus of bacteria from the family of Brucellaceae. So far, only one species of this genus is known.

Paenochrobactrum is a genus of Gram-negative, oxidase-positive, non-spore-forming, nonmotile bacteria of the family Brucellaceae.

Pseudochrobactrum is a genus of bacteria from the family of Brucellaceae.

Farrell's medium is a selective bacteriological medium for Brucella species which is prepared by the addition of six antibiotics to a basal bacteriological medium such as serum dextrose agar. In order to prepare 1 liter of the Farrell's medium, the following quantities are added to 1 liter of serum dextrose agar: polymyxin B sulfate, bacitracin, natamycin (50 mg), nalidixic acid (5 mg), nystatin, and vancomycin (20 mg). Vancomycin inhibits the growth of gram-positive bacteria on this medium, while nystatin inhibits the growth of fungi. Other antibiotics inhibit the growth of gram-negative bacteria other than Brucella species, thus favoring the exclusive growth of the latter in this medium.

Brucella papionis is a Gram-negative, non-spore-forming and non-motile bacteria from the family of Brucella which has been isolated from baboons.

Brucella vulpis is a Gram-negative, non-spore-forming and non-motile bacteria from the family of Brucella which has been isolated from the mandibular lymph nodes of foxes.

Arsenicitalea is a genus of bacteria from the family of Brucellaceae with one known species.
