Brucellosis is a zoonotic disease caused by Brucella. Brucella can replicate within various host cells and evade the host immune system, which underpins its pathogenicity. Rough Brucella strains, characterized by the absence or inadequacy of the O-antigen chain, exhibit incomplete lipopolysaccharide structures, precluding the production of anti-lipopolysaccharide antibodies. This distinguishing feature facilitates differential diagnosis and has attracted considerable attention. Rough Brucella can invade and manipulate the host immune system via low endotoxin activity, lysosomal escape, and resistance to complement attacks. Nevertheless, comprehensive investigations into the host immune responses, rough Brucella-host interaction mechanisms, and virulence gene functions of rough Brucella remain scarce. This article elucidates the intracellular parasitism process of rough Brucella and the molecular mechanisms underlying their interactions with hosts, with the aim of offering insights for the development of effective vaccines against rough Brucella.
