Gingipains do not affect the colonization and survival of P. gingivalis in infected lungs. a The survival of P. gingivalis was assessed by counting the number of CFU in lung homogenates collected every 24 h for 3 days (n = 24). b Infection was monitored for up to 10 days by examining lung homogenates. For P. gingivalis persistence in the infected lungs of 8-week-old mice, see online supplementary figure S3.
