Bacterial burden in wild-type CYL11481 (WT) and its isogenic mgrA mutant (MT) in rat cardiac vegetations. Homogenized heart vegetation (100 µL) from each time point of the WT and mgrA mutant strains were quantitatively cultured onto tryptic soy agar plate and incubated at 37°C for 24 hours. Data represent colony-forming units (CFU) log10/g of tissue from 5 to 9 rats per time-point with P value. Statistical significance was analyzed by Student t test. ***Highly significant; **Significant.
