Obligate intraerythrocytic apicomplex protozoan
In Europe: Babesia canis, Babesia vogeli
Theileria annae (Babesia microti-like), Babesia gibsoni
In Europe it can be transmitted only by ticks: Dermacentor reticulatus (in cooler regions) or Rhipicephalus sanguineus (in warmer regions)

In many European countries this protozoan infection is the most common and most serious tick-transmitted infectious disease affecting dogs. Cases of autochthonous babesiosis have already been reported in several countries such France, Germany, Hungary, Italy and the Netherlands.
It is a seasonal disease (spring and autumn) but this may, however, change drastically if Rhipicephalus sanguineus is involved, an endophillic tick which infests kennels and can be active all year round.
Haemolytic anaemia and hypotensive shock leading to fever, anaemia, thrombopaenia, eosinopaenia, lymphopaenia and haemolysis.
Changes in the colour of the urine (from yellow to orange and sometimes almost black) constant urinary bilirubin.
Epidemiological elements + Clinical signs
Anaemia, leukocytosis, thrombocytopenia and morphological elements can be observed with a microscope in the red blood cells after blood smears
Immunodetection such an indirect fluorescent antibody.
Other causes of anaemia: intoxication with raticides, canine monocytic ehrlichiosis, immuno-anaemia, other causes of fever, dejection, anorexia etc.
- Imidocarb dipropionate injection administered according to variable protocoles.
- Possible recovery with no after-effects, even with no treatment, due to effective, natural resistance of animal.
Symptomatic treatment must be associated with the specific treatment of the exposed animals.
- Ixodicides and protecting the dog against ticks.
- Vaccination is possible in some countries (antigens obtained from a culture of B. canis)
Most cases of babesiosis are detected in South Africa where the infection is caused by Babesia felis.
Babesia cati or Cytauxzoon felis are detected in the US but rarely found in Europe.
