Several agents can cause hemoparasitic diseases in dogs, and blood-sucking arthropods transmit these diseases. These agents can cause several clinical manifestations and, in some cases, can kill the host. Because these agents are essential in animal health, this study aims to detect the frequency of Ehrl...
As doenças transmitidas por carrapatos são afecções de grande importância na clínica médica de pequenos animais, devido à alta casuística e ampla distribuição vetorial no território brasileiro. Os principais agentes responsáveis pelas infecções em cães são Babesia sp., Ehrlichia canis e ...

Abstract Ehrlichia canis is the main etiological agent of canine monocytic ehrlichiosis (CME), a globally canine infectious disease. In Brazil, CME is considered to be endemic, and its prevalence can reach 65% in some states. The diagnosis of ehrlichiosis is important for treatment and epidemiological pu...

Ehrlichia infections in cattle are frequent in Africa but have also been reported in Brazil and North America. This paper reports natural infection by Ehrlichia sp. associated with Babesia bigemina and Anaplasma marginale in a calf in the municipality of Campo Grande, state of Mato Grosso do Sul, Brazil,...
Resumen La ehrlichiosis es una enfermedad transmitida por la picadura de garrapatas que afecta a perros y humanos, causada por las especies Ehrlichia canis y E. chaffeensis, respectivamente. Estas bacterias son gramnegativas, intracelulares obligadas, de aspecto cocoide a pleomorfo, que infectan los mono...
Canine monocytic ehrlichiosis (CME) is an infectious disease caused by the bacterium Ehrlichia canis and transmitted by Rhipicephalus sanguineus sensu lato, a tick with worldwide distribution. When not diagnosed and treated early, disease can be severe. Currently, the disease is confirmed by serological ...
Abstract Ehrlichiosis is caused by agents belonging to Ehrlichia genus. Despite the frequent reports on the serological and molecular detection of E. canis in dogs in Brazil, there is scant data on ehrlichiosis in brazilian cats. This study aimed at investigating the occurrence of Ehrlichia spp. in dome...
Abstract Occurrence of infection or exposure to Ehrlichia canis, Hepatozoon canis and Rickettsia spp. was detected in feral cats living in two fragments from Atlantic rainforest, in Natal, RN, Brazil, and in dogs living around the parks. While serum samples were collected from 155 animals (53 cats livin...

Abstract Arthropod-borne pathogens are medically important because of their ability to cause diseases in their hosts. The purpose of this study was to detect the occurrence of Ehrlichia spp., piroplasmids and Hepatozoon spp. in dogs with anemia and thrombocytopenia in southern Brazil. EDTA-whole blood w...

Abstract INTRODUCTION Peripheral blood of 400 dogs infected with Leishmania and Ehrlichia were analyzed using polymerase chain reaction (PCR), and clinical signs were characterized. METHODS PCR and parasitological tests were conducted. RESULTS PCR was positive for Leishmania in 84.75%, and parasito...
