Seroprevalence of Ehrlichia canis, Ehrlichia chaffeensis and Ehrlichia ewingii in dogs in North America [PDF]

Parasites & Vectors, 2012
This study evaluated the exposure of dogs to three different Ehrlichia spp. in the south and central regions of the United States where vector-borne disease prevalence has been previously difficult to ascertain, particularly beyond the metropolitan areas.Dog blood samples (n = 8,662) were submitted from 14 veterinary colleges, 6 private veterinary ...

Ehrlichia spp. close to Ehrlichia ruminantium, Ehrlichia canis, and “Candidatus Ehrlichia regneryi” linked to heartwater-like disease in Kenyan camels (Camelus dromedarius)

Tropical Animal Health and Production, 2021
We present findings from an outbreak of a heartwater-like disease in camels that killed at least 2000 adult animals in Kenya in 2016. Clinical signs included excitability, head pressing, aimless wandering, recumbency, and fast breathing followed by death after about 4 days. The observed morbidity in one herd was 40% with an average mortality of 7.5% in

Ehrlichia and Anaplasma

EDIS, 2021
Ehrlichia and Anaplasma are bacteria that cause diseases, known as ehrlichiosis and anaplasmosis, in humans and other animals. Ehrlichia and Anaplasma are primarily transmitted through the bites of infected hard ticks, such as the lone star tick, the blacklegged tick, and the American dog tick.

Molecular and serological detection of Ehrlichia spp. in cats on São Luís Island, Maranhão, Brazil Detecção molecular e sorológica de Ehrlichia spp. em gatos da ilha de São Luís, Maranhão, Brasil

Revista Brasileira de Parasitologia Veterinária, 2012
Ehrlichiosis is a tick-borne disease that affects both humans and animals. The few existing reports on ehrlichiosis in Brazilian cats have been based on observation of morulae in leukocytes and, more recently, on molecular detection of Ehrlichia sp.

Molecular characterization of novel Ehrlichia genotypes in Ixodes auritulus from Uruguay

Current Research in Parasitology and Vector-Borne Diseases, 2021
Ehrlichia are small intracellular Gram-negative bacteria transmitted by ticks. These microorganisms cause ehrlichiosis, a complex of life-threatening emerging zoonoses and diseases of global veterinary relevance.

Ehrlichia Infection in Italy [PDF]

Emerging Infectious Diseases, 1998
Immunoglobulin M seroconversion to Ehrlichia chaffeensis was documented in U.S. citizens bitten by ticks in Sardinia. Seven cases of suspected ehrlichiosis in local residents were not confirmed by laboratory tests. In Alpine areas antibodies to E. phagocytophila were detected in persons at high risk, i.e., foresters (8.6%) and hunters (5.5%), and in ...

Molecular detection of Ehrlichia spp. in ticks parasitizing wild lagomorphs from Spain: characterization of a novel Ehrlichia species

Parasites & Vectors, 2022
Background Several species belonging to the genus Ehrlichia are considered pathogenic for animals and humans. Although wildlife are known to play an important role in the epidemiology of these bacteria, information on the role of wild lagomorphs in their

Sequential Evaluation of Dogs Naturally Infected withEhrlichia canis,Ehrlichia chaffeensis,Ehrlichia equi,Ehrlichia ewingii, orBartonella vinsonii [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACTHistorically, disease manifestations in dogs seroreactive toEhrlichia canisantigens by indirect immunofluorescent antibody testing have been attributed to infection with eitherE. canisorEhrlichia ewingii. A 1996 study by Dawson and colleagues provided PCR evidence that healthy dogs from southeastern Virginia could be naturally infected ...
