From: Serological signature of tick-borne pathogens in Scandinavian brown bears over two decades
Anti-Borrelia IgG response of the Scandinavian brown bears differed among age groups and areas in Sweden. The anti-Borrelia IgG antibody response of the bear sera was expressed as a percentage of the mean of the positive controls (mice experimentally infected with B. afzelii). Each combination of age group and area contained serum samples from all years of the study (1995 to 2012). The north and south study areas are shown in grey and white, respectively. Shown are the median (black line), the 25th and 75th percentiles (edges of the box), the minimum and maximum values (whiskers), and the outliers (solid circles)
