The present study reports the isolation of Trueperella abortisuis from pooled foetal stomach contents of aborted swine foetuses from a single sow in North-East Scotland, United Kingdom. The organism was not isolated in purity; however a diagnosis of fetopathy due to T. abortisuis was made, due to predominant growth of the bacterium in addition to confirmative histopathological findings. As far as the authors are aware, this is the first report of the isolation of T. abortisuis from porcine abortion material in the United Kingdom.

BACKGROUNDTrueperella abortisuis (formerly known as Arcanobacterium abortisuis) was initially described by Azuma et al in 2009, 1 based on isolation of the bacterium from a placenta of a sow following abortion in Japan. Subsequently, the bacterium was isolated from pigs in Germany and the US. [2][3][4][5] Isolation from cats and a dog has also been reported. 6 We report the isolation of T. abortisuis from the stomach contents of aborted swine foetuses in the United Kingdom.
CASE PRESENTATIONA 450-sow breeding herd in North-East Scotland with a weekly batch farrowing system reported four abortions within a 3-week period in April 2019. Replacement gilts were homebred. Routine vaccination of adult breeding stock against E. coli, rotavirus, porcine circovirus type 2 and parvovirus was practised. Service was by AI only, with boars used as teasers. Five pig foetuses were submitted to Scotland's Rural College Veterinary Services Centre at Aberdeen for post-mortem examination and investigation.
