Molecular detection of Babesia vogeli, Ehrlichia canis and Anaplasma platys in a hospital population of dogs clinically diagnosed with hemoparasitosis
| Resumo: | There is an increase in tick-borne diseases in dogs in urban and rural areas in Brazil and some of these are of public health importance. Rhipicephalus sanguineus-transmitted hemoparasitoses are the main causes of mortality in dogs. The present study investigated the molecular occurrence of Ehrlichia canis, Babesia vogeli and Anaplasma platys in dogs with clinical sings and hematological abnormalities suggestive of tick-borne diseases. These dogs were seen at a Veterinary Hospital of a Public University between January 2014 and December 2016, and were evaluated through anamnesis, clinical examination and complementary exams. The polymerase chain reaction technique was used to detect the presence of hemoparasites DNA. From the 461 dogs that were tested for B. vogeli, 10.6% (49/461) were positive, the associated variable was age. Regarding the 730 animals screened for E. canis, 15.1% (110/730) were positive, and the infection was associated with hematocrit and number of platelets. Relative to the 86 samples evaluated for A. platys, 15.1% (13/86) were positive, and no variable presented statistical significance. From the animals positive for B. vogeli, no of these showed positivity by qPCR for Rangelia vitalii. It is concluded that the occurrence of hemoparasitosis in dogs from the Londrina region is common. Therefore, it is emphasized that molecular techniques should be used as an auxiliary tool for the differential diagnosis of the different etiological agents causing hemoparasitosis. Additionally, these molecular tools are essential for better investigation and preventive assertiveness because it allows to detect parasite DNA. |
