Rhem et al. (41) and Elasri et al. (42) stated the role of the Cna protein in the osteomyelitis due to S. aureus, but according to the study of Elasri et al. (42), this protein does not have any important contribution in human skeletal muscle infections, though it contributes to human S. aureus keratitis. The gene discussed is PPP3CA; the disease is osteomyelitis.
