We use a lymph-node with M. avium intercellulare as control. 

Two questions about Fite's (actually we perform Wade's) stain:

1. what kind of mycobacteria are only Wade/Fite positive and Ziehl-Neelsen
negative or do atypical mycobacteria (like M.murinum) stain also with an
ordinary Ziehl-Neelsen? I'm not aware of any article regarding this topic.

2. as it's not easy to find groundnut-oil (at least here in Europe), is it
possible to use other "brands" like olive-oil?
