anaplasma phagocytophilum in danish sheep: confirmation by dna sequencing.the presence of anaplasma phagocytophilum, an ixodes ricinus transmitted bacterium, was investigated in two flocks of danish grazing lambs. direct pcr detection was performed on dna extracted from blood and serum with subsequent confirmation by dna sequencing.200920025738
transmission differentials for multiple pathogens as inferred from their prevalence in larva, nymph and adult of ixodes ricinus (acari: ixodidae).ixodes ricinus serves as vector for a range of microorganisms capable of causing clinical illness in humans. the microorganisms occur in the same vector populations and are generally affected by the same tick-host interactions. still, the instars have different host preferences which should manifest in different transmission patterns for various microorganisms in the tick populations, i.e., most microorganisms increase in prevalence rate from larvae to nymphs because their reservoirs are among s ...201728255923
