Vector-borne pathogens in ticks and EDTA-blood samples collected from client-owned dogs, Kiev, Ukraine

Due to the availability of adequate habitats in urban environments, e.g. city parks and recreational green areas, ticks from such settings may also carry pathogens of veterinary and public health concern. Thus, tick-borne infections may readily be identified in companion animals residing in urbanised areas. To investigate the presence of vector-borne pathogens in Kiev, Ukraine, 52 engorged adult ticks, 33 Dermacentor reticulatus and 19 Ixodes ricinus, were collected from 15 dogs in the spring of 2010, and further 23 canine EDTA-blood samples were obtained in the spring of 2011 from client-owned patients presented in a veterinary clinic in Kiev. DNA of 9 pathogens was detected by PCR in ticks and canine EDTA-blood samples: Babesia canis canis, Anaplasma phagocytophilum, Rickettsia helvetica, Ri. monacensis, Ri. raoultii, and Dirofilaria repens (by proxy) were identified in engorged ticks and B. c. canis, Hepatozoon canis, Di. immitis, Di. repens, and Mycoplasma haemocanis in canine EDTA-blood samples. This is the first description of Ri. raoultii in the Ukraine. This study adds information on the occurrence of vector-borne pathogens of veterinary and public health importance in Kiev, Ukraine.
