Brucella

 [broo-sel´ah]
a genus of gram-negative, aerobic, nonmotile cocci or rod-shaped bacteria, the etiologic agent of brucellosis. B. abor´tus, which causes infectious abortion in cattle, is the most common cause of infection in humans; other species pathogenic for humans are B. meliten´sis, found in goats and sheep, and B. su´is, found in swine.

brucella

 [broo-sel´ah]
any member of the genus Brucella. adj., adj brucel´lar.

Brucella

(brū-sel'lă),
A genus of encapsulated, nonmotile bacteria (family Brucellaceae) containing short, rod-shaped to coccoid, gram-negative cells. These organisms do not produce gas from carbohydrates and are parasitic. They invade all animal tissues and infect the genital organs, the mammary gland, and the respiratory and intestinal tracts; are pathogenic for humans and various species of domestic animals. The type species is Brucella melitensis.

Brucella

/Bru·cel·la/ (broo-sel´ah) a genus of schizomycetes (family Brucellaceae). B. abor´tus causes infectious abortion in cattle and is the most common cause of brucellosis in humans. B. bronchisep´tica is another name for Bordetella bronchiseptica. B. su´is usually infects swine, but can also cause severe disease in humans.

brucella

(bro͞o-sĕl′ə)
n. pl. bru·cellae (-sĕl′ē) or bru·cellas
Any of various aerobic, short, rod-shaped bacteria of the genus Brucella that are pathogenic to humans and domestic animals.

Brucella

A genus of gram-negative, nonmotile, non-encapsulated coccobacilli of unresolved taxonomy, which grows slowly on blood and chocolate agars. It is a facultative intracellular pathogen and causes brucellosis.

Accepted species
B melitensis, B abortus, B suis, B ovis, B neotomae, B canis, B ceti, B pinnipedialis, B microti, B inopinata.

Bru·cel·la

(brū-sel'lă)
A genus of encapsulated, nonmotile bacteria containing short, rod-shaped to coccoid, gram-negative cells. These organisms are parasitic, invading all animal tissues and causing infection of the genital organs, the mammary gland, and the respiratory and intestinal tracts, and are pathogenic for humans and various species of domestic animals.

Brucella

a genus of gram-negative rods in seven species and several biotypes. The cause of many serious diseases in animals, including brucellosis.

Brucella abortus
a short rod or coccobacillus which causes brucellosis in cattle and horses, and is a serious zoonosis. Two strains of reduced virulence and used for vaccination in cattle are Strain 19 and Strain 45/20.
Brucella canis
a similar organism to the other brucellae except that it is inhibited in growth by a 10% concentration of CO2, a cultural enhancement for the other species. Causes brucellosis in dogs.
Brucella melitensis
a rod so short that it is easily mistaken for a coccus with the same characteristics as the other brucellae. Causes brucellosis in goats and Malta fever in humans, a serious zoonosis. Rev1 strains are used for vaccination but have zoonotic risk.
Brucella neotomae
found only in the desert wood rat in the USA.
Brucella ovis
has staining and cultural characteristics similar to the other brucellae. Causes brucellosis in rams.
Brucella suis
a typical brucella in morphology and cultural and staining characteristics. Causes brucellosis in pigs and is a significant zoonosis.
