Chlamydia are isolated by :
Isolation of chlamydiae can done by :
Inoculationinto yolk sac/embryonated eggs of 6-8 day old chick embryo which may be pretreated by streptomycin or polymyxin
Inculation into experimental animals (mice)
Tissue/cell culture :
Preferred mode
Commonly used cell lines are McCoy and HeLa cells.
Cell cultures are pretreated by irradiation or chemicals such as 5-iodo – 2 deoxyuridic or cycloheximide to enhance replication and detection of inclusion bodies.
Pretreatment with DEAE dextrax or centrifugation after inoculation, promotes contact between chlamydiae particles and cell monolayer.
Enzyme immune assay
Yolk sac inoculation
Direct immunofluorescence
Micro immunofluorescence
