MAVS and infection: Most previous studies have focused on hVISA and VISA strains isolated from blood [2]–[6], whereas we found in the present study that hVISA and VISA strains were identified from diverse infection sites, and the predominant source of hVISA and VISA isolates was sputum (56.3%, p<0.001), followed by pus (18.8%), blood (8.8%), secretions 6.3%), drainage (3.8%), and other (6.3%).
