coxiella burnetii pathogenesis: emphasizing the role of the autophagic pathway

coxiella burnetii (c. burnetii), the etiological agent of the q fever disease, ranks among the most sporadic and persistent global public health concerns. ruminants are the principal source of human infections and diseases present in both acute and chronic forms. this bacterium is an intracellular pathogen that can survive and reproduce under acidic (ph 4 to 5) and harsh circumstances that contain coxiella-containing vacuoles. by undermining the autophagy defense system of the host cell, c. burnetii is able to take advantage of the autophagy pathway, which allows it to improve the movement of nutrients and the membrane, thereby extending the vacuole of the reproducing bacteria. for this method to work, it requires the participation of many bacterial effector proteins. in addition, the precise and prompt identification of the causative agent of an acute disease has the potential to delay the onset of its chronic form. moreover, to make accurate and rapid diagnoses, it is necessary to create diagnostic devices. this review summarizes the most recent research on the epidemiology, pathogenesis, and diagnosis approaches of c. burnetii. this study also explored the complicated relationships between c. burnetii and the autophagic pathway, which are essential for intracellular reproduction and survival in host cells for the infection to be effective.
