Dogs are a reservoir for Chagas disease, caused by Trypanosoma cruzi (T. cruzi), and other companion vector-borne diseases, including ehrlichiosis (Ehrlichia canis Ehrlichia ewingii), anaplasmosis (Anaplasma phagocytophilum Anaplasma platys), dirofilariasis (Dirofilaria immitis) Lyme disease (Borrelia burgdorferi). This study has two key objectives: 1) to determine seroreactivity against T. in ...

Canine vector-borne diseases (CVBDs) pose a diagnostic challenge, particularly when a dog is coinfected with more than one pathogen. The purpose of this study was to generate information about the diagnosis of CVBDs in young dogs following their first exposure to flea, tick, sand fly, louse, and mosquito vectors. From March 2008 to May 2009, 10 purpose-bred young naive beagle dogs and a cohort ...

BACKGROUND Although tick-borne diseases are important causes of morbidity and mortality in dogs in tropical areas, there is little information on the agents causing these infections in the Caribbean. METHODOLOGY We used PCRs to test blood from a cross-section of dogs on St Kitts for Ehrlichia (E.) canis, Babesia (B.) spp., Anaplasma (A.) spp. and Hepatozoon (H.) spp. Antibodies against E. can...

The aim of the study was to determine the prevalence of Ehrlichia canis, Anaplasma platys and Babesia spp. in dogs. It describes the practice of veterinarians in detecting tick-borne diseases in Nueva Ecija, Philippines. Seventy blood samples were collected and were subjected to multiplex PCR for the detection of E. canis, Babesia spp. and A. platys. The prevalence of babesiosis is the highest ...

Zoonosis Update T he term ehrlichiosis has been broadly applied to a variety of diseases of humans and animals caused by pathogens formerly classified in the genus Ehrlichia. However, a recently proposed taxonomic reorganization 1 has recommended the reclassifications of some former Ehrlichia species under the genera Anaplasma and Neorickettsia and Cowdria ruminantium under the genus Ehrlichia....

Ehrlichioses are important emerging zoonotic tick-borne diseases that can affect both animals and humans. Clinical manifestations of ehrlichiosis caused by different members of Anaplasmataceae in dogs are similar to each other and to other diseases showing systemic manifestation. The observation of inclusions in white blood cells and in platelets cannot be used to confirm the Anaplasmataceae et...

Worldwide importance of tick born diseases (TBDs) in dogs has been accepted due to its high morbidity and mortality. The disease gets transmitted by the brown dog tick, Rhipicephalus sanguineus, which acts as a vector of several agents such as Anaplasma platys, Babesia canis vogeli, Babesia gibsoni, Ehrlichia canis (E. canis), spotted fever group Rickettsia spp. and Hpatozoone canis (H. canis) ...
