Abstract
Background and Aim:Canine tick-borne diseases are important diseases with a worldwide distribution. In Thailand, the most important canine tick-borne diseases are ehrlichiosis, babesiosis, and hepatozoonosis. This study aimed to determine the serum protein electrophoresis patterns (SPEPs) and C-reactive protein (CRP) levels associated with Ehrlichia canis, Babesia canis, or Hepatozoon canis single infections.Materials and Methods:A total of 650 canine blood samples were collected from animal hospitals and clinics in Bangkok and its vicinity to examine health status and blood parasite infection. Suspected blood parasite infections were examined by buffy coat thin blood smear and confirmed by polymerase chain reaction. Normal dog and positive E. canis, B. canis, and H. canis single infections and serum protein profiles were determined by agarose gel electrophoresis. CRP concentration was measured by fluorescent immunoassay.Results:In dogs infected with E. canis, B. canis, and H. canis single infections, albumin levels and A/G ratios significantly decreased, whereas β2-globulin levels increased (p<0.05). The γ-globulin level significantly increased in E. canis and H. canis infections (p<0.05). A monoclonal gammopathy pattern wasi observed in E. canis and B. canis sngle infections, whereas β-γ bridging patterns and increased β- and γ-globulin fractions were found in H. canis single infections. The CRP level increased in dogs with blood parasite single infections and may be related to the pathogenesis of the infection.Conclusion:SPEPs and CRP levels can be used to monitor health status and blood parasite problems in infected dogs.
Highlights
Canine tick-borne diseases are transmitted by hard tick species, such as the brown dog tick (Rhipicephalus sanguineus), which is common in Thailand [1] and is distributed worldwide [2]

Summary
Canine tick-borne diseases are transmitted by hard tick species, such as the brown dog tick (Rhipicephalus sanguineus), which is common in Thailand [1] and is distributed worldwide [2]. Babesia canis vogeli, and Hepatozoon canis are commonly found in Thailand [4,5]. Ehrlichiosis and babesiosis can develop when a dog is bitten by an infected tick, but hepatozoonosis is caused by its ingestion. B. canis subspecies vogeli is the main species causing canine babesiosis in Thailand [5]. In Thailand, the most important canine tick-borne diseases are ehrlichiosis, babesiosis, and hepatozoonosis. This study aimed to determine the serum protein electrophoresis patterns (SPEPs) and C-reactive protein (CRP) levels associated with Ehrlichia canis, Babesia canis, or Hepatozoon canis single infections
