Additions and Modifications

S. M Bell

A technical note entitled ‘Additions and Modifications to the Range of Antibiotics Tested by the CDS Method of Sensitivity Testing’, published by “Pathology” (1988, 20, 303‑304).

 Update of the CDS Sensitivity Test

 The Microbiology Clinical Update Program edited by Nerissa Lee published an Update of the CDS Sensitivity Test in 1984. In this publication we undertook a major revision of the test and extended the method to test those antibiotics which had been developed since the original modification was published.
