Esta amostra de E. Cienc Rural ; 38 3: The study included a non-probabilistic sample of domiciled adult dogs aged one year or older. The dog owners who participated in the study completed an epidemiological questionnaire, from which was acquired information about factors that could act as risk factors for infection, such as the erlichisoe of ticks, contact with other dogs, habitat, age, and gender.

Rev Bras Cien Vetv. Services on Demand Journal. Prevalence of Ehrlichia canis Rickettsiales: October 02, ; Accepted: This finding may be explained by the fact that diagnosis by IFA is more effective in the advanced stages of the disease, with reduced sensitivity in csnina initial phase of infection leading to false negatives.

Molecular detection of tick-borne bacterial agents in Brazilian and exotic captive carnivores. Molecular and serological detection of spp. Canis familiares Ensaios e Cienc ; 12 2: Ticks Tick Borne Dis ; 3 4: The negative and positive controls used for the dogs were canine sera on which serology had been performed in a prior study CARLOS et al.

The nested-PCR test identified 43 positive animals that did not have detectable levels of anti- E. Ehrlichia J Wildl Dis ; 46 3: Dean AG, Arner T. Ticks Tick Borne Dis ; 5 5: Veterinary Recordv. Discussion This study found that The transmission of ehrlichiosis relichiose the tick vector requires the presence of an infected dog, so increased contact between dogs increases the chances of exposure to a tick vector infected with E. Furthermore, this study identified factors associated with exposure to the agent in dogs in this locality.


However, it was lower than the values found by Nakaghi et al.

Of the dogs evaluated, 16 had positive results with all of the diagnostic techniques, and had negative results in all of them. Risk factors and clinical disorders of canine ehrlichiosis in the South of Bahia, Brazil.

In addition to the above mentioned points, because serological caniba identifies only antibodies, a positive case on serology may appear negative on PCR testing because of eradication of the Ehrlichia organisms by the immune system.

Results were compared between diagnostic techniques. Infections with Babesia canis and Ehrlichia canis in dogs in Zimbabwe.

Collection of biological samples After the dogs were physically restrained, 8 mL of canine venous blood was collected by puncture of the jugular or cephalic vein. Recent advances in canine infectious disease. J Clin Microbiolv.

The aims of this study were to detect the presence of Ehrlichia spp. The risk factors associated with exposure to the agent in this study were corroborated by Azevedo et al. Therefore, young dogs may be protected from infection because older animals have greater contact time with the bacteria over the course of their lives AZEVEDO et al. Dogs that had any contact with other dogs residents or not and those that were parasitized by the ticks of R.

In the initial phase, when there is elichiose higher parasitemia, there are more chances of finding infected leukocytes in the blood smear; however, in the subclinical and chronic phases of the disease, the chances of finding infected leukocytes decrease, which can result in false-negative results.

The dog owners were older than 18 years of age and, at the time of the visit, were responsible for the household. Comparison of nested PCR with immunofluorescent-antibody assay for detection of Ehrlichia canis infection in the dogs treated with doxycicline. Rev Infect Dis ; 10 Suppl 4: Subsequently, to identify the species E.

Serological diagnosis of canine monocytic ehrlichiosis with Brazilian antigen of Ehrlichia canis

Ehrlichia canis J Clin Microbiol ; 36 1: The cell culture showed to be infected by Ehrlichia on day 27 by PCR and on day 28 by cytological staining. The first study was conducted using blood samples of pet dogs treated at the Veterinary Hospital of the State University of North Fluminense Darcy Ribeiro. However, false positives can also occur, because other structures may be mistaken for the morulae or inclusions of Ehrlichia spp.
