My name is Sverre Skeidsvoll, 31 year old bio-engineer (student) in Norway.
It's the first time to visit this newsgroup. Great site !!
My problem is as follows:
We have used same enterococci to grow against trimethoprim in two different media.
Media nr.1 was from Mueller-hinten and showed enterococci sensitiv to trimethoprim !
Media nr.2 was from Gibco and showed the same enterococci resistant to trimethoprim !
I cannot understand why this same bacteria is sensitiv and then resistant in two media
that should be the same. Different agar ?
Please help me !
