Abstract

  • Hippobosciadae, as bloodsucking arthropods, represent a potential vector of bacterial pathogens like Bartonella spp. These bacteria are able tocause dermatitis and febrile diseases in their hosts. The aim of the study was to investigate wheter the ruminant-related Hippoboscidae Hippobosca equina, Lipoptena cervi, Lipotena fortisetosa and Melophagus ovinus in Saxony are positive on this causative agent. In this study 107 adult Hippoboscidae flies (11 Hippobosca equina, 22 Lipoptena cervi, 62 Lipoptena fortisetosa, 12 Melophagus ovinus) and 11 pupae of Melophagus ovinus were analyzed by PCR targeting the citrate synthase gene gltA. 47% of the flies were positive of Bartonella spp., whereby the distribution within the species was as follows: H. equine 82%, L. cervi 59%, L. fortisetosa 26%, M. ovinus 100%. Also the pupae of M. ovinus proved positive. The results show that the Hippoboscidae in Saxony are positive tested for Bartonella spp. but the presence vary among the species. The positiv results of the pupae of Melophagus ovinus confirm the vertical transmission within these species. Whether Melophagus ovinus trnsmits Bartonella spp. to the hos has to be examined by futher investigations of the invested sheep. The same applies to the other louse flies of mammals. For better specification of pathological incidents it is of great importance to know which Bartonella species occur in the examined Hippoboscidae. Moreover it is the aim to investigate louse flies of birds with a wide host range and additionally louse flies of common swift and swallows because of the close proximity to people and farm animals for Bartonella spp and other pathogens which are significant for human and veterinary medicine.
