| a new pcr assay for the detection and differentiation of babesia canis and babesia vogeli. | babesia spp. are globally distributed tick-borne protozoan parasites that infect the red blood cells of a wide range of vertebrate hosts, including humans. diagnosis of babesiosis is often impeded by the transient presence of the parasites in peripheral blood, as well as by their pleomorphic nature. given the reports of an expanding and, in some cases, sympatric geographical distribution of babesia canis and babesia vogeli in dogs and associated vectors, in europe, the development of time-effici ... | 2017 | 28739301 |
| canine tick-borne diseases in pet dogs from romania. | tick-borne diseases are of substantial concern worldwide for animals as well as humans. dogs have been a human companion for millennia, and their significant impact on human life renders disease in dogs to be of great concern. tick-borne diseases in dogs represent a substantial diagnostic challenge for veterinarians in that clinical signs are often diffuse and overlapping. in addition, co-infections with two or more pathogens enhance this problem further. molecular methods are useful to disentan ... | 2017 | 28335825 |
