Classification Chlamydiaceae, Chlamydophila
Deposited As Chlamydia pneumoniae Grayston et al.
Agent Chlamydophila pneumoniae
Strain TWAR strain 2023
Applications
Respiratory research
Biosafety Level 2

nasopharynx of human patient with pneumonia
Product Format frozen
Storage Conditions -70°C or colder
Comments
This preparation has tested positive for Mycoplasma contamination.
Note that activities with high potential for aerosol production require BSL 3 facilities and practices.
Forms intracellular inclusions which react with specific anti-C. pneumoniae monoclonal antibodies and monoclonal antibodies directed against the chlamydia LPS.
Inclusions will not stain with iodine or monoclonal antibodies against the MOMP of C. trachomatis. Infection is enhanced by centrifugation and use of cycloheximide (1 to 2 mcg/ml) in medium.
Suggested protocol for propagation: Add glass beads and vortex preparation to disrupt cells. Infect monolayer with disrupted material. Centrifuge at 3000 x rpm (750 x g) for 1 hour.
Feed with fresh growth medium containing FBS prescreened for Chlamydia antibodies and 1-2 ug/mL cycloheximide. Incubate at 37°C for 72 hours.
