PATHOGENICITY. Brucella spp are facultative intracellular bacteria that have the ability to avoid the killing mechanism and proliferate within the macrophages, similar to other intracellular pathogens. To be a successful infectious agent, Brucella requires four steps: adherence, invasion, establishment, and dissemination within the host Opsonised and non opsonised Brucella can infect macrophages.
Brucellosis is an infectious disease caused by bacteria termed Brucella; the disease is found mainly in animals (zoonotic infection), but humans can be infected with these bacteria.; Brucellosis has been described as long as 2,000 years ago, and the organisms finally were identified in 1887; the disease is worldwide and usually confined to animals.

Brucellosis is a global zoonosis caused by Gram-negative, facultative intracellular bacteria of the genus Brucella (B.). Proteomics has been used to investigate a few B. melitensis and B. abortus strains, but data for other species and biovars are limited. Hence, a comprehensive analysis of proteomes will significantly contribute to understanding the enigmatic biology of brucellae.
Abstract. Mice vaccinated with living or killed BCG become resistant to infection with Brucella abortus, as evidenced by a lower bacterial count in the spleen and liver as compared to controls.Some of the observed resistance is attributed to the ability of the treated mice to mobilize quickly a large number of macrophages in the abdominal cavity, since these macrophages could phagocytose and.
Brucellosis in humans occurs when a person comes into contact with an animal or animal product infected with the Brucella bacteria. Very rarely, the bacteria may spread from person to person.
Brucella spp. are facultative intracellular pathogens that have the ability to survive and multiply in professional and non-professional phagocytes, and cause abortion in domestic animals and undulant fever in humans.Several species are recognized within the genus Brucella and this classification is mainly based on the difference in pathogenicity and in host preference.
