Serum susceptibility of Lyme borreliae exposed to bird serum samples. a Each genospecies and the respective avian species was independently challenged with serum samples from three individual birds, except for the sera of Eurasian blackbirds (Turdus merula, n = 2). b Percentage of viable spirochetes after 6 h of incubation with avian sera. The data represents three independent experiments for each Borrelia genospecies/bird species combination
