Vector Competence
For hard (Ixodid) ticks it is virtually impossible for mechanical transmission to occur on its own (i.e. without some replication), as they tend to not take multiple blood meals from different hosts in the one stage. Passing an organism between tick stages (trans-stadial transmission) seemingly requires that an organism can also replicate within the tick.

Famous quotes containing the word competence:
“Such is the confidence that we have through Christ toward God. Not that we are competent of ourselves to claim anything as coming from us; our competence is from God, who has made us competent to be ministers of a new covenant, not of letter but of spirit; for the letter kills, but the Spirit gives life.”
—Bible: New Testament, 2 Corinthians 3:4-6.
