CONTAMINATION AND ERADICATION


We have encountered M. hyorhinis contamination in cell-cultures issued as mycoplasma-free (1997 & 1999). An example of mycoplasma isolation from a vaccine seed is also shown below.

Cell culture isolations from other laboratories may be submitted for attempted identification against our bank of antisera to common contaminants.

Where a unique cell-culture is found to be contaminated we can offer eradication based upon antibiotic plus specific antiserum treatment inclusive of in process and final mycoplasma testing coincident with storage of mycoplasma-free stocks.
