// Of course not, Danny//
dry your eyes, all of you
You are not vetinerary pathologists - ( cries and sobs of what dat den?)
interspersed - interpunctutated even with those stifled sobs young children emit
A tuberculin test ( which ws used ) will show positive once there has been an infection - so all of us ( TB or BCG ( or both, (me)) would react positive
er Llamas dont get BCG so a positive result is past infection
which may or may not be active ( there now - silently killing....)
The results have been sent off for culture and that is a 6-week suck. You use a medium in old speak called Lowenstein Jensen which just about kills everything else so that TB can grow. You do it by adding copper ions
and classify the colonies as ruff tuff or buff - colour chromogen
and grow in dark, or light ( phoophile I think) and stain ( AFB of course)
and yes by that time everyone has lost interest or is dead.
since you anticipate a negative test, you cant do all the whizzy modern things which are quick quick quick but tend to miss cases
