Plain-English summary
A group of 200 dogs in Brazil were tested for canine ehrlichiosis, a tick-borne disease that can cause symptoms like anemia and low platelet counts. The study found that 36% of the dogs tested positive for the disease, with risk factors including living in urban areas and having ticks. Some dogs showed signs of illness, and blood tests confirmed the presence of the Ehrlichia canis bacteria. Treatment typically involves antibiotics, which can help improve the dogs' health if they are diagnosed early.

Abstract
The aim of this work was to study the clinical disorders and risk factors of canine ehrlichiosis in Ilhéus and Itabuna, Bahia, and compare different diagnostic methods. Blood samples were collected from 200 dogs. Each dog was clinically examined. A questionnaire was used to evaluate the risk factors. The blood samples were analyzed using the Dot-ELISA test; hematometry, platelet counts and searches for morulae on blood smears were performed. Nested PCR was carried out on 50 serologically positive samples and 50 negative samples. Three positive PCRs were sequenced. Thirty-six percent were serologically positivity and 5.5% from blood smears. The animals were anemic and thrombocytopenic. Presence of ticks and living in areas on the urban periphery were considered to be risk factors (p < 0.05). Nested PCR identified 11 positive dogs of which nine were serologically positive and two were negative. The DNA sequencing was consistent with the presence of Ehrlichia canis.
