Affected population The affected horse was born in May 2008 and kept in the holding concerned since November 2014. On 26 November 2014 a blood sample has been taken for export purposes to a Third country with respect to glanders. The horse showed no clinical signs and has been kept separately from other horses during the pre-export quarantine. The complement fixation test showed a positive result (Land Laboratory); the Friedrich-Loeffler Institute (FLI) (National Reference Laboratory for Glanders) confirmed the result and revealed also a positive result with the immunoblot method. A second blood sample was taken and the results of this investigation confirmed the first results. As there was no epidemiological evidence for the infection, the affected horse has been culled for diagnostic purposes on 13 December 2014. The bacteriological investigations of the organs showed negative results for Burkholderia mallei. The investigation of skin samples with immunohistological methods showed doubtful results. Further investigation of scabs of skin samples (fixed in formalin) with PCR showed positive results. The infection with Burkholderia mallei was confirmed on 27 January 2015.

Epidemiological comments The affected holding has been put immediately under restriction following the first serological positive test (1 December 2014). All other equines of the affected holding have been investigated three times every two weeks with negative results. The affected equine has been culled for diagnostic purposes. Cleansing and disinfection of the affected holding has been carried out and finished on 27 January 2015. The infection with B. mallei has been resolved from 27 January 2015. Epidemiological investigations have started with the help of Friedrich-Loeffler Institute . It is known that the affected animal had never been moved outside of Germany. There might have been indirect contacts to South America. The source of infection is still unknown.
