Molecular prevalence and haemato-biochemical profile of canine monocytic ehrlichiosis in dogs in and around Hisar, Haryana, India

AbstractThe present study was planned to investigate the molecular prevalence of canine monocytic ehrlichiosis (CME) in dogs in and around Hisar and to evaluate the haemato-biochemical profile for its better management. A total of 60 dogs presented to Medicine Section, TVCC, LUVAS, Hisar with the history of naturally acquired tick infestation and clinical signs consistent with CME were screened on the basis of blood smear examination, followed by molecular detection by nested PCR assay targeting a portion of 16S rRNA gene ofEhrlichia canis. Nested PCR detected 18 cases positive forE. canis with estimated 30% percent positivity as compared to 8.33% (5 out of 60) by blood smear examination. These 18 dogs confirmed for CME by nested PCR were assessed for clinical and haemato-biochemical profile. Breed-wise prevalence indicated maximum number of cases in Labrador retriever, followed by Pug, Rottweiler and German shepherd dog with more number of cases in male dogs. Age-wise prevalence revealed highest number of cases in more than 1  year age group, followed by 6 months to 1 year age group and least in less than 6 months aged dogs. Pyrexia, anorexia and pale to congested mucous membranes were the main clinical signs observed, followed by lethargy, vomiting. Less common clinical signs were epistaxis, lymphadenomegaly, hind l imb weakness, malena, ocular discharge, followed by haematuria, corneal opacity, nasal discharge and coughing, icterus, dermal petechiae and ecchymoses.
