We have had similar difficulty with both sensitivity disks of a single
concentration and with the E test.  This is probably why NCCLS does not
have a policy on using the disks for anaerobic culture sensitivities. 
They can't recommend the E test for anaerobes OR aerobes because it is
available only from a single manufacturer and is a unique product.
