Surviving inside a macrophage: the many ways of Brucella

Abstract

Bacteria of the genus Brucella are intracellular pathogens capable of survival and replication within macrophages of mammalian hosts. Recent advances have shed light on virulence factors and host functions involved at various stages of the Brucella intracellular life cycle. This review focuses on how this pathogen uses multiple strategies to circumvent macrophage defense mechanisms and generate an organelle permissive for replication.
