Sanjeet asked about a "Fite control" - I suppose Mycobacterium leprae infected tissue for the Fite-Faraco modification of the visible-light acid-fast stain.
It actually is necessary to use Myco. leprae (which of course is unculturable) rather than Myco. tuberculosis when staining for lepra bacilli. I've asked this question several times over the years and never got the faintest reply, but - the North American armadillo (Dasypus novemcinctus) is easily infected with human leprosy, and in fact is naturally infected in Louisiana. One lepradillo could I think provide control material for the entire planet. Has such material ever become available? Two more questions: Can you perform the fluorescent (auramine O) acid-fast stain with the Fite modification? And - do you also need a different control for Mycobacterium avium-intracellulare (MAI)?
