At K = 2, an East-West cline of cluster assignment was observed in North America, and the predominant cluster in western North America (in green; Fig. 3B) was also found in Eastern Europe, Beijing and the two Australian populations.
PFGE comparison of isolates from a predominant cluster in South Africa with an isolate from the Hajj outbreak showed that they were related (data not shown).
So, each of these (tentative) taxonomy specific or predominant clusters were probed, using PSI_BLAST, in the Uniref90 sequence database which is a comprehensive collection of protein sequences from diverse organisms.
All predominant clusters apart from CAS1 strains were equally distributed in the country suggest a continual transmission of strains.
Then, it performs an N-D clustering on the metadata to search for predominant clusters.
In this analysis, almost all individuals demonstrated membership of multiple clusters, but some populations displayed membership of predominant clusters that corresponded to geographical affiliation.
Also, at the level of microsatellite loci, up to nine different genetic clusters were detected for Fernandina and Isabela, whereas a single predominant cluster is found in populations from most other islands.
We found that the last group (cluster 14) is the predominant cluster and is also displayed in the time range from 4000 to 5000 ps; the cluster 14 also appears most predominant in frame numbers, and the middle structure (4260 ps) of cluster 14 is regarded as representative frame.
The predominant cluster from this analysis is depicted in Figure 7. Briefly, peptidyl-prolyl cis-trans isomerase A (PPIA) and heat shock protein 27 kda (HSPB1) increase the expression of superoxide dismutase-1 (SOD1), which regulates catalase (CAT).
Although the direct wave component has vanished in NLOS cases, similarly, these NLOS paths also show relatively predominant cluster property.
