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:
“Love and work are viewed and experienced as totally separate activities motivated by separate needs. Yet, when we think about it, our common sense tells us that our most inspired, creative acts are deeply tied to our need to love and that, when we lack love, we find it difficult to work creatively; that work without love is dead, mechanical, sheer competence without vitality, that love without work grows boring, monotonous, lacks depth and passion.”
—Marta Zahaykevich, Ucranian born-U.S. psychitrist. “Critical Perspectives on Adult Women’s Development,” (1980)
