Brucellosis in humans is a zoonosis of greatly varied clinical image. It occurs on all inhabited continents. The course of the disease may be acute, sub-acute or chronic. The etiologic factors of brucellosis are small, aerobic Gram-negative rods of the genus Brucella, which currently contains ten species: B. abortus, B. suis, B. ovis, B. melitensis, B. canis, B. neotomae, B. pinnipedialis, B. c...

A series of 27 strains of six species of Brucella was tested for susceptibility in vitro to a representative cross section of antibiotics in current use. The activity against each species was plotted, with the cumulative per cent of strains inhibited indicated for each concentration. As a class, the tetracycline antibiotics were the most effective. Erythromycin, gentamicin, streptomycin, and ka...

Brucellosis presents with many clinical manifestation that make its diagnosis a difficult task. Ever since the report of the first serologic test for brucellosis, a definitive diagnostic technique has been actively pursued. The most widely used methods of diagnosis are based on serology, which measures the ability of the serum (antibody) to agglutinate a standardised amount of killed Brucella a...

La brucelosis canina es causa de falla reproductiva y la detección temprana en los perros infectados sigue siendo un desafío. El objetivo del presente estudio fue probar dos antígenos para ser utilizados diferentes inmunoensayos, infección por Brucella canis perros: uno a partir antígeno crudo sonicado RM6/66 (CA-iELISA) otro utilizando proteína inmunodominante GroEL (GroEL-iELISA). Se determin...
