Additional file 2: Figure S1. of Epidemiology, genetic variants and clinical course of natural infections with Anaplasma phagocytophilum in a dairy cattle herd

Overview of the herd seroprevalence during one season (based on the data shown in Table 2). First samples were taken in May shortly before the animals went to pasture. Despite two animals with a titre of 1:50 (dark asterisk), no measurable antibody titres were detected. This changed over the following months (x- axis). The left y-axis shows the percentage of seropositive animals (blue, cows; green, heifers). Logarithmic titres are given on the right y-axis. Boxplots in gray display the median titre (black bars), upper and lower quartile and the upper wisker. Outliers (asterisks) were found in May and January. In January only two heifers had antibody titres of 1:100 and 1:200, while 10 further animals had a remaining antibody titre of 1:50 (darker asterisk). (TIFF 54 kb)
