Naturally occurring ehrlichiosis in Egyptian dogs

Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes associated with canine ehrlichiosis in Egyptian dogs; microscopic examination failed to provide definitive diagnosis of canine ehrlichiosis. Season did not greatly influence the disease; the type of ticks involved in the disease transmission in Egypt was Rhipicephalus sanguineus.
