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

Reorganization of genera in the families Rickettsiaceae and Anaplasmataceae in the order Rickettsiales: unification of some species of Ehrlichia with Anaplasma, Cowdria with Ehrlichia and Ehrlichia with Neorickettsia, descriptions of six new species combinations and designation of Ehrlichia equi and [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2001
The genera Anaplasma, Ehrlichia, Cowdria, Neorickettsia and Wolbachia encompass a group of obligate intracellular bacteria that reside in vacuoles of eukaryotic cells and were previously placed in taxa based upon morphological, ecological, epidemiological and clinical characteristics.

Prevalence and Sequence Analysis of Vector‐Borne Zoonotic Diseases in Stray Cats in Istanbul [PDF]

Vet Med Sci
Istanbul, the largest metropolis in Türkiye, is home to a notable population of stray cats. While cats enrich the city's culture, they can also transmit various diseases, posing diagnostic challenges for clinicians. This study aimed to detect infections in stray cats using PCR and sequencing to identify Ehrlichia, Anaplasma, Bartonella, Hepatozoon ...

Prevalence of vector-borne pathogens Ehrlichia canis, Babesia spp. and Dirofilaria immitis in dogs in Townsville, far north Queensland. [PDF]

Aust Vet J
Ehrlichia canis, Babesia spp. and Dirofilaria immitis are blood‐borne pathogens transmitted to dogs by arthropods. The aim of the current study was to investigate the prevalence of E. canis, Babesia spp. and D. immitis in domestic dogs, aged 6 months or older, in Townsville, in far north Queensland, Australia.

Current Distribution of Selected Vector‐borne Diseases in Domestic Dogs From Bucharest, Romania [PDF]

Vet Med Sci
Serological testing of 317 dogs in Bucharest (2020‐2024) revealed an overall Canine vector‐borne diseases (CVBD) seroprevalence of 8.8%, with Dirofilaria immitis (12.62%) being the most common. Shelter and older dogs had higher infection rates. Climate change and vector expansion may influence pathogen spread, underscoring the need for enhanced ...

Host-parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati). [PDF]

Med Vet Entomol
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Novel Anaplasmataceae agents Candidatus Ehrlichia hydrochoerus and Anaplasma spp. Infecting Capybaras, Brazil

Emerging Infectious Diseases, 2022
We amplified Ehrlichia and Anaplasma DNA from Amblyomma dubitatum tick–infested capybaras (Hydrochoerus hydrochaeris) in southern Brazil. Sequencing of 16S rRNA, sodB, and groEL indicated a novel Ehrlichia species, and sequencing of 16S rRNA from 2 ...
