A range of isolates has been employed as information on differences in virulence between isolates helps to guide choices for regulatory agencies and researchers involved in monitoring programmes and for the conduct of host range tests.
isolates 93024, 08041, 08049, 08063, 08094 and 08095; Table 1) Miniaturized microarray analysis also identified the likely presence of dihydrofolate reductase (dfrA1, dfrA12, dfrA13), as well as sul1, that mediates resistance to sulmethoprim, in a range of isolates that were resistant to sulphamethoxazole/trimethoprim (Table 1).
In pea, the sbm1 resistance gene is effective against both BYMV [4] and a range of isolates of PSbMV [5] with lines carrying the dominant SBM1 allele being universally susceptible to PSbMV, unless a second unlinked recessive resistance (sbm2) was present [6].
LPS-based serologic assays should use a range of isolates representative of known LPS types.
The majority of sequences are derived from environmental surveys of nifH, although the database also contains sequences obtained from a range of isolates.
Although the majority of sequences are derived from environmental surveys of proteorhodopsin genes, the database also contains sequences obtained from a range of isolates or large genomic DNA fragments bearing a 16S rRNA gene copy.
The vaccine approach is problematic because of the variability of the parasite adhesion ligand PfEMP1, although initial exploratory studies are underway (Refs 163, 164, 165), and some preliminary data do support the possibility that crossreactive antibodies can be active against a range of isolates (Refs 166, 167).
Here we investigated the cefazolin levels in serum, saliva and bronchial secretions postoperatively and compared them with the MIC of a range of bacteria isolated from the oral cavity of the patients.
Spike discrimination on-line was achieved with pairs of voltage time windows and principal component analysis (Abeles & Goldstein, 1977); typically, 5 8 electrodes in the array picked up neuronal activity and 1 3 spikes could be confidently discriminated per electrode, giving a range of 8 15 isolated VPL neurons.
Five sets of novel genus-specific primers were designed and tested in reverse-transcription polymerase chain reaction assays against a range of virus isolates in plant virus diagnostic laboratories in both Australia and New Zealand.
