Hela cells were infected with C. trachomatis serovars L2 or D, C. muridarum Mouse pneumonitis (MoPn), C. caviae (GPIC), or C. pneumoniae AR-39 (Cpn). At various times post infection (C. trachomatis L2, C. caviae = 24 hrs; C. trachomatis serovar D, C. muridarum = 36hrs; C. pneumoniae = 72hrs) cells were fixed, permeabilized and labeled with an species-appropriate anti-EB (green) and anti-active kinase (Tyr419) (red) antibodies. Images were acquired on a Zeiss LSM 510 Meta confocal microscope. Active kinase is recruited to the C. trachomatis and C. pneumoniae inclusions, but not to C. muridarum or C. caviae. Scale bar = 10 μm.
