Mycoplasma detection by culture isolation

Often regarded as the gold standard method for mycoplasma detection, the culture isolation detection method uses a combination of selective growth media and incubation conditions to positively enrich for any mycoplasma present in a sample. Most mycoplasma contaminants can be detected by growth on standardised agar, with the exception of certain strains of M.hyorhinis.

Colonies of mycoplasma exhibit a distinctive "fried egg" morphology (see image) when viewed under a plate microscope. The assay requires a 28 day test interval before a definitive result can be obtained.

We offer the culture isolation method which meets FDA points to consider in characterisation of cell lines to produce biologicals (1993) as a service.
