Ticks and tick‐borne bacterial pathogens found on hard ticks (Acari: Ixodidae) on cattle in the Central River region of The Gambia

Medical and Veterinary Entomology, Volume 40, Issue 1, Page 91-100, March 2026.
First detection of Ehrlichia minasensis, Anaplasma marginale and hemotropic Mycoplasma spp. in cattle in The Gambia. Identification of four tick species, with Hyalomma marginatum being the most common. 15.6% of ticks tested positive for tick‐borne pathogens, including Ehrlichia spp., A. marginale and hemotropic Mycoplasma spp.

Ehrlichia chaffeensis replication sites in adult Drosophila melanogaster [PDF]

International Journal of Medical Microbiology, 2013
Ehrlichia chaffeensis is a Gram-negative, obligate intracellular bacterium which causes the tick-borne disease human monocytic ehrlichiosis. In vertebrates, E. chaffeensis replicates in monocytes and macrophages. However, no clear cell or tissue tropism has been defined in arthropods. Our group identified two host genes that control E.

Estrategia de Ehrlichia Chaffeensis para Evitar el Mecanismo de Defensa Celular en Ehrlichiosis Monocítica Humana

, 2023
Introduction. There are different vectors in the transmission of diseases in animals and humans; After mosquitoes, ticks are the second vector, which are of concern for public health, due to their morbidity and mortality in humans around the world.

Novel Magnetic Resonance Imaging Findings of Bilaterally Symmetrical Lesions in a Dog With Concomitant Granulomatous Meningoencephalitis and Necrotizing Encephalitis

Veterinary Radiology &Ultrasound, Volume 67, Issue 1, January 2026.
ABSTRACT A 3‐year‐old, female neutered Bichon Frise was presented with a 2‐day history of behavioral changes and ataxia. The neurological examination was consistent with diffuse forebrain involvement, with left lateralization. An MRI study identified bilaterally symmetrical T2W/T2 fluid‐attenuated inversion recovery (T2‐FLAIR) hyperintense, T1W ...

Natural Infection of Domestic Goats withEhrlichia chaffeensis [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACTThirty-eight domestic goats from an area ofEhrlichia chaffeensisendemicity were tested for antibodies reactive toE. chaffeensisand forE. chaffeensis-specific 16S rRNA gene fragments by an indirect fluorescent antibody test and a nested PCR assay, respectively. Twenty-eight of 38 (73.7%) goats had antibodies reactive toE.

New insights into molecular Ehrlichia chaffeensis-host interactions [PDF]

Microbes and Infection, 2010
Ehrlichia chaffeensis is an obligately intracellular bacterium that exhibits tropism for mononuclear phagocytes and survives by reprogramming the host cell. Here we review new information regarding the newly characterized effector molecules and the complex network of molecular host-pathogen interactions that the organism exploits enabling it to thrive ...
