[show abstract][hide abstract] ABSTRACT: ABSTRACT: After publication of this work Hansen MGB, Christoffersen M, Thuesen LR, Petersen MR, Bojesen AM: Seroprevalence of Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum in Danish horses it has come to our attention that one of the references used in the article Butler CM, et al Anaplasma phagocytophilum infection in horses in the Netherlands, has been incorrectly cited. The sentence "The seroprevalence of A. phagocytophilum in Europe varies from 83.3% in Holland" in the second paragraph of the Background section of the article is incorrectly written and should state "The PCR detection of A. phagocytophilum in Europe varies from 9.8% in Holland" instead. The authors apologise for any confusion caused.

However, the extend to which Danish horses are infected and seroconvert due to these two bacteria is unknown. The aim of the present study was to evaluate the seroprevalence of B. burgdorferi sensu lato and A. phagocytophilum in Danish horses.
A total of 390 blood samples collected from all major regions of Denmark and with a geographical distribution corresponding to the density of the Danish horse population were analyzed. All samples were examined for the presence of antibodies against B. burgdorferi sensu lato and A. phagocytophilum by the use of the SNAP 4DX ELISA test.
Overall, 29.0% of the horses were seropositive for B. burgdorferi sensu lato whereas 22.3% were seropositive for A. phagocytophilum.
Antibodies against B burgdorferi sensu lato and A. phagocytophilum are commonly found among Danish horses thus showing that Danish horses are frequently infected by these organisms.
