Table 2 Infection rates of A. phagocytophilum in questing I. ricinus , divided by life stage

From: Circulation of four Anaplasma phagocytophilum ecotypes in Europe

Stage Tested (n) Positive (n) Infection rate (CI)
Larvae 386 5 1.3% (0.4-3.0%)
Nymph 3090 68 2.2% (1.7-2.8%)
Adult 306 18 5.9% (3.5-9.1%)
Female 113 5 4.4% (1.5-10.2%)
Male 193 13 6.7% (3.6-11.2%)
  1. The 95%-confidence intervals, which were calculated using Fisher's exact test, are between brackets. The infection rate of adults is significantly higher than larvae or nymphs (p < 0.05).
