causing anemia, with the example of ehrlichiosis are thoroughly investigated. But in Brazil
there are no studies to estimate the incidence of anemia in different species and so little,
studies that assess the extent and causes related to the problem. Thus, it was developed this
study to diagnose and assess the rates of anemia in male and female dogs of different breeds,
ages and various conditions of health and nutritional management, but no clinical signs of
anemia, and to evaluate the metabolic profile of these animals. We evaluated 148 dogs with
anemia that was identified in 40% of the animals, most of then was normochromic normocitic
(NNA) in type. It was concluded from the analyzed data that anemia is a significant
occurrence, even in asymptomatic dogs. The nutritional deficiency especially of copper and
iron, parasites and liver failure were not related to the occurrence of anemia among the
animals studied. In this study we highlight the chronic infection with Ehrlichia canis and
Anaplasma platys, and periodontal disease (PD) as chronic infectious/inflammatory diseases
as likely causes of the NNA between the animals studied. The treatment of PD and evaluation
of inflammatory markers would be useful for elucidation of the causes of anemia in the herd
studied. === Instituto de Veterin?ria, Universidade
Federal Rural do Rio de Janeiro, Serop?dica, RJ, 2009. Em c?es diversas enfermidades que
cursam com anemia a exemplo da erliquiose s?o exaustivamente estudadas. Contudo, n?o
existem no Brasil estudos para estimar a incid?ncia de anemia em diferentes esp?cies e, t?o
pouco, estudos que avaliem a dimens?o e as causas relacionadas ao problema. Assim,
desenvolveu-se o presente estudo visando diagnosticar e avaliar os ?ndices de anemia em c?es
machos e f?meas, de diferentes ra?as, idades e condi??es diversas de manejo nutricional e
sanit?rio, mas sem sinais cl?nicos de anemia, bem como avaliar o perfil metab?lico desses
animais. Foram avaliados 148 c?es, sendo que anemia foi identificada em 40% dos animais, a
maioria do tipo normoc?tica normocr?mica (ANN). Conclui-se pelos dados analisados que
anemia tem ocorr?ncia significativa, mesmo em c?es assintom?ticos. A defici?ncia nutricional,
especialmente de cobre e ferro, as parasitoses e insufici?ncia hep?tica n?o estiveram
relacionadas ? ocorr?ncia de anemia entre os animais estudados. Neste estudo destacam-se as
infec??es cr?nicas por Ehrlichia canis e/ou Anaplasma platys e a doen?a periodontal (DP),
como enfermidades infecciosas /inflamat?rias cr?nicas causadoras prov?veis da ANN entre os
animais estudados. O tratamento da DP e a avalia??o de indicadores inflamat?rios seriam ?teis
para elucida??o das causas da anemia no rebanho estudado.
