Chlamydial inclusion trafficking and fusion is dynein dependent. Cos7 cells were infected with C. trachomatis serovar L2 following micro-injection with anti-dynein antibodies. Uninjected cells were infected in parallel. Twenty-four hours postinfection, cells were fixed and stained with human sera (red) and the appropriate secondary for the anti-dynein antibody (green). Representative picture of anti-dynein injected cells at 6 and 24 hpi (A and B, respectively). Inclusions per infected cell were enumerated for injected and uninjected cells at 24 hpi, P < 0.0001 (C).
