From: Serological signature of tick-borne pathogens in Scandinavian brown bears over two decades
Anti-Borrelia IgG response of the Scandinavian brown bears over time differed between areas. The anti-Borrelia IgG response in the bear sera is shown for the entire study (year 1 = 1995 and year 18 = 2012). The anti-Borrelia IgG antibody response of the bear sera (optical density) 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 contains serum samples from all age classes. 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)
