Abstract

Canine babesiosis is a tickborne, protozoal, haemoparasitic disease. Babesia organisms are frequently classified as either large (B. canis) or small (B. gibsoni). The aim of this study was an attempt to detect B. gibsoni DNA in blood samples taken from dogs suspected of suffering from tick-borne diseases. 216 samples were tested using PCR, of which, in 99 of them B. canis DNA was detected, whereas in 3 of them B. gibsoni was detected. Positive PCR results for B. gibsoni were confirmed using a Qube MDx real-time analyzer. The results indicate that infections with this B. gibsoni should be taken into account and included in the differential diagnosis of vector-borne diseases in dogs in Poland, and that the accurate identification of the species of parasite causing the infection is crucial for developing the correct treatment regimen and prognosis.

Abstract

Borreliosis is the most frequently diagnosed tick-borne disease caused by spirochete bacteria belonging to the genus Borreliae - Borrelia burgdorferi sensu stricto (s.s.), Borrelia afzelii and Borrelia garinii. Clinical manifestations in dogs include fever, lameness, polyarthritis and glomerulonephritis. Diagnosis is mainly serological and is based on an immunoenzymatic test followed by a Western blot confirmatory test. Early treatment with antibiotics such as doxycycline or amoxicillin, for four weeks, usually reduces the risk of chronic disease. Tick control, including tick repellents, is highly reliable in preventing transmission. Vaccines are available to reduce transmission and the clinical manifestations of infection in dogs. Bernese Mountain Dogs are a breed that often test positive for antibodies against B. burgdorferi without showing any clinical symptoms of the disease. Quantitative determination of the immunoglobulin level for spirochetes has indicated that Bernese Mountain Dogs may have an increased susceptibility to Borrelia spp. infections of a hereditary nature.

Abstract

The aim of this study was to analyze cases of granulocytic anaplosmosis diagnosed in 53 hunting dogs in Poland. Medical records of dogs naturally infected with Anaplasma phagocytophilum were retrospectively evaluated with regard to clinical signs and laboratory abnormalities at the time of presentation, therapy and course of disease. The most common clinical signs in A. phagocytophilum-positive dogs included in the study were lethargy (100%), inappetence (94%) and fever (92.5%). Thrombocytopenia was the most common laboratory abnormality (100%), followed by a drop in haematocrit level (79.3%) and increased AST activity (75.5%).
Of the 53 infected dogs, 51 (96%) recovered and two dogs (with neurological symptoms) died.
Analysis of these cases indicates that A. phagocytophilum infection must be considered in differential diagnosis in dogs living in Poland, especially in hunting dogs with thrombocyto- penia and Ixodes ricinus tick invasions.

Abstract

Canine hepatozoonosis is a tick-borne protozoal disease. Two species of Hepatozoon may infect dogs: Hepatozoon americanum and H. canis. The aim of the paper was to attempt to detect the genetic material of H. canis in blood samples collected from dogs suspected to suffer from tick-borne diseases. 107 samples were tested with the use of the real-time PCR technique (Vcheck M Bionote analyser), of which 99 were collected from dogs which never left Polish territory (group 1) and 8 from dogs which spent the holidays with their owners in Turkey (group 2). DNA of H. canis was detected in 1 dog in group 1 (with Ixodes ricinus infestation), and in 2 dogs in group 2 (with Ripicephalus sanguineus infestation). The results obtained indicate that infections with H. canis should be taken into account and included in the differential diagnosis of vector-borne diseases in dogs in Poland, and the accurate identification of the infection agent is crucial for developing the correct treatment regimen and prognosis.
