Figure 2. . . Mean reservoir competence of 14 host species (10 mammals and 4 birds) for Anaplasma phagocytophilum, southeastern New York, USA, 2008–2010. Error bars indicate SE. Reservoir competence is defined as the mean percentage of ticks infected by any individual host of a given species. For inclusion, sample sizes for a species had to be >4 in >2 years. No species showed significant variation in reservoir competence across years (p>0.10, by 2-way analysis of variance or Kruskal-Wallis test as appropriate, for all species tested). Single-letter abbreviations for genera along the left indicate Blarina, Didelphis, Peromyscus, Procyon, Sciurus, Tamias, Catharus, and Turdus, respectively.
