Mycoplasma testing of ATCC VR-1477 by direct method in broth and agar showed positive results. 
FBS used to culture Chlamydia must be prescreened to verify that the serum does not contain antibodies to Chlamydia or other factors that would interfere with growth.
This strain is a tissue culture-adapted version of strain TW-3 (VR-578) which is grown in embryonated chicken eggs.
Before infecting host cells, add 1-mm glass beads and vortex stock material for 45 seconds. Aspirate fluid. Infect shell vial monolayer with 0.2 mL of material.
Centrifuge at 800 x G for 1 hour. Feed with 1.0 mL EMEM (HEPES buffered), 10% FBS (screened for chlamydia antibodies).
