Immunity against Brucella abortus depends on the recognition of pathogen-associated molecular patterns (PAMPs) by pattern recognition receptors (PRRs). Signaling pathways triggered by Brucella DNA involves TLR9, AIM2 and possibly STING and MAVS. Herein, we review the advances in B. abortus DNA sensing by host innate immune receptors and the progress in this field.
