Vaccines (lect 4) Flashcards
How is the source of infection genotyped?
Multilocus sequence typing.
Attribution experiment.
What is MLST?
Reveals interspecies hybrids
What is bottom-up and top-down?
Bottom-up:
Start with DNA and test effects on the phenotype
Top-down:
Start with phenotype and associates it with particular genomic elements
What is Genome Wide association study? (GWAS)
Looking at similarities of the biochemistry of different strains
How many people die of infectious and parasitic diseases every year?
10million
What is horizontal gene transfer?
The transfer of genes between DIFFERENT genomes. Can occur between prokaryote and eukaryote species.
