We are writing to comment on the article by Arraga-Alvarado and others in the September 2014 issue of The American Journal of Tropical Medicine and Hygiene. 1 To provide some necessary background information about the early recognition of ehrlichiosis and anaplasmosis in Venezuela, we would like to bring to the attention of the manuscript's authors and readers an article published by de Tamí an...

The efficacy of doxycycline treatment (10 mg/kg of body weight every 24 h for 42 days) in eliminating Ehrlichia canis from four subclinically infected dogs was evaluated. One dog remained PCR positive, suggesting that 6 weeks of doxycycline treatment may not be sufficient to clear E. canis parasites from all subclinically infected dogs. Serology (indirect immunofluorescent antibody assay) was s...

Three dogs which were carriers of Babesia canis were infected with Ehrlichia canis. These animals developed clinical signs and haematological evidence of ehrlichiosis and made an uneventful recovery, despite the fact that they were subsequently treated with doxycycline only. Three control dogs which were also carriers of B. canis were clinically normal, despite the fact that they showed a disti...

Canine monocytic ehrlichiosis (CME) is a potentially fatal tick-borne disease caused by the rickettsia Ehrlichia canis (16). The etiologic agent was first recognized in Algeria in 1935 (8). Since then, it has been reported worldwide, causing extensive morbidity and mortality among domestic dogs and other canids (11, 28, 51). The principal vector of CME is Rhipicephalus sanguineus (11). Recently...

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....

The present study was conducted to explore the prevalence of canine monocytic ehrlichiosis (CME) in dogs and around Meerut district for its better clinical management. A total 366 dog’s blood samples were collected from Department Veterinary Clinical Complex, SVPUAT, nearby private Clinics with history tick infestation characteristic findings CME screened on basis smear examination, followed by...
