Susceptibility testing of Mtb complex isolates by phenotypic methods requires a minimum of 14 days from a primary specimen.
Generally, typeability and accuracy of bovine CNS identification are higher for genotypic methods than for phenotypic methods.
Ribotyping shows a quite good correlation with phenotypic methods, although it has been possible to identify 15 different clusters.
Current phenotypic methods are not suitable to accurately distinguish all the species belonging to the C. albicans complex.
In the majority of healthcare facilities, the routine detection of ESBL production by Enterobacteriaceae is actually carried out by phenotypic methods (Pitout and Laupland 2008).
After cultivation, a varied set of isolates were detected using both phenotypic methods and PCR analysis of 16S rRNA (Randazzo et al. 2002).
This applies also to the study of Helicobacter pylori where current genotypic (molecular) methods are important complements or alternatives to phenotypic methods.
The phenotypic methods for identification of antifungal resistance are reliable procedures, and MIC determination by reference techniques is the gold standard to detect resistant clinical isolates.
Standard phenotypic methods for antiviral resistance testing are labor and time-intense and molecular resistance determinants are insufficiently understood for routine diagnostic use of genotypic resistance testing.
Identification is confirmed by traditional phenotypic methods (4 ).
Phenotypic methods are therefore favored by many practitioners.
