Progressos na imunização contra Anaplasma marginale [PDF]

Pesquisa Veterinária Brasileira, 2003
Até o presente momento, as imunizações contra anaplasmose em rebanhos bovinos utilizam organismos vivos ou mortos. No entanto, esforços têm sido realizados nos últimos anos com o objetivo de desenvolver uma nova geração de vacinas. A membrana externa de Anaplasma marginale é capaz de induzir reposta imune protetora contra desafio homólogo e ...

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.

Acaricidal activity of small molecule antagonists of the tick kinin receptor against Rhipicephalus microplus acaricide‐susceptible and resistant strains

Pest Management Science, Volume 82, Issue 2, Page 1618-1628, February 2026.
Two small molecules, SACC‐0039590 and SACC‐0428788, killed cattle fever tick, R. microplus, susceptible Deutch strain and pyrethroid resistant Arauquita strain larvae. SACC‐0039590 at 1 mM decreased the reproductive parameters of Deutch females. Abstract BACKGROUND Resistance to acaricides underscores the need for tick control alternatives.

Rickettsia Bellii and Anaplasma Marginale

, 2023
Anaplasma marginale is an obligate intracellular gram-negative bacterial pathogen of ruminants. It is the etymological agent of bovine anaplasmosis, which is the most prevalent tick-borne cattle disease in the word. Despite its prevalence and severe economic impacts, few effective control measures exist for A. marginale. Antibiotic treatment, acaricide
