Changes in the cell densities of M. aeruginosa cultures infected with Ma-LMM01 at various MOIs. Exponentially growing cultures of M. aeruginosa were inoculated with Ma-LMM01 at MOIs of 10−1 (○), 10−3 (▵), 10−5 (□), 10−7 (◊), and 10−9 (▿). As a control, an M. aeruginosa culture was inoculated with an autoclaved phage suspension (•).
