Plain-English summary
A group of dogs in Recife, Brazil, were tested for tick-borne infections, and nearly half were found to have Anaplasma platys or Ehrlichia canis, which can cause symptoms like fever and lethargy. The study showed that 23.9% of the dogs had infections from two or more of these pathogens at the same time. This is significant because it highlights the prevalence of these infections in the area, and it’s the first report of some of these pathogens in dogs from Pernambuco. Treatment typically involves antibiotics, and many dogs can recover well with prompt veterinary care.

Abstract
To identify DNA of the main tick-borne pathogens in dogs from Recife (Brazil), polymerase chain reactions were carried out on blood samples of dogs treated at the Veterinary Hospital of the Universidade Federal Rural de Pernambuco from March 2007 to June 2008. The detection of DNA was performed using specific primers. Amplicons were analyzed through electrophoresis and sequencing. A phylogenetic tree was constructed using the UPGMA method, revealing that the sequences were closely related to those of strains from other geographic regions. Among the 205 blood samples analyzed, 48.78% was positive for Anaplasma platys; 38.04% was positive for Ehrlichia canis; 7.31% was positive for Babesia canis vogeli; and 0.49% was positive for Hepatozoon canis and Mycoplasma haemocanis. Coinfection of two or three pathogens was found in 23.9% (49/205) of the dogs. The subspecies B. canis vogeli was identified. Infection by H. canis and M. haemocanis is reported for the first time in dogs in the state of Pernambuco (Brazil). The data indicate that the main tick-borne pathogens in dogs in this region are E. canis and/or A. platys, followed by B. canis vogeli.
