- Abstract
Background Ashworthius sidemi, a blood-sucking nematode, is a primary parasite of Asiatic cervides, primarily sika deer (Cervus nippon). As A. sidemi infections are common in bison, red and roe deer, and gastrointestinal nematodes are often exchanged between animals, it is possible that other farm animals such as cows and sheep that may use the same pastures can be infected. Hence, histopathological changes observed in the walls of the abomasa and duodena of infected wildlife caused by a strong parasite presence may become an important health problem also for farm animals. Methods In the present study, a simple PCR test for the detection of A. sidemi infection in European bison based on DNA from third stage infective larvae (L3) has been optimized. Results The species-specific primers generated a 406 bp fragment, and A. sidemi DNA could be detected at concentrations of 0.1 pg/íl. The specificity of PCR was confirmed by the use of the genomic DNA of adult Ostertagia circumcincta, Haemonchus contortus, Cooperia spp. as negative controls. Conclusion It is possible to detect A. sidemi infection in European bison using DNA from L3. If this nematode infection is transmitted to cows this method may be effective to diagnose invasion in breeding animals in vivo.
