[Histonet] Pneumocystis carnii staining

From:"Karen Harmon"

We use a GMS stain to demonstrate pneuomcyctis with successful results about 50% of the time.   We have taken this procedure apart step by step, solution by solution and are at our wits end to determine the cause for failure.  I can assure you that over the past 3 weeks, there is no variable that we have not tried.    The ironic part is we never have a problem  demonstrating fungi with the GMS, in fact, we never had any problems at all with other silver procedures.

Can anyone help with our hit and miss problem with pneumocystis?
