Flow cytometry was used to determine: (A) – percentage of pneumococci positive for bound C3; (B) – mean fluorescent intensity of pneumococci with bound C3; and (C) – deposition index calculated by multiplying the percentage of pneumococci positive for C3 by their fluorescent intensity. Both the mean fluorescent intensity (*: = 0.04) and deposition index (**: = 0.01) were significantly lower for organisms recovered from the lungs of cirrhotic vs. control rats.
