Ehrlichia ruminantium infects Rhipicephalus microplus in West Africa [PDF]

Parasites & Vectors, 2016
The invasion of West Africa by Rhipicephalus microplus during the past decade has changed the ecological situation of the agent of heartwater Ehrlichia ruminantium in this area. Before, its local vector, Amblyomma variegatum, was the most abundant tick species found on livestock. Today, the abundance of the R.

In silico analysis for identification of tick phagotopes selected by phage-displayed libraries Análises in sílico na identificação de fagotopos de carrapatos selecionados por bibliotecas de phage display

Revista Brasileira de Parasitologia Veterinária, 2009
Phage display techniques have been widely employed to map epitope structures which have served as the basis for developing molecular vaccines. We have applied this technique to map specific epitopes of Rhipicephalus (Boophilus) microplus.

Propagation de parasites transportés avec leurs hôtes : cas exemplaires de deux espèces de tiques du bétail [PDF]

, 2010
Les tiques, comme tous les parasites, peuvent facilement être disséminées avec leurs hôtes. Parasites obligatoires de vertébrés auxquels elles sont fixées pendant une période plus ou moins longue, elles sont bien adaptées à ce mode de transport. Une fois

Gonadulin and Insulin‐Like Growth Factor Involved in Rhipicephalus microplus Reproduction

Entomologia Experimentalis et Applicata, EarlyView.
Insulin‐like growth factor (IGF2) in ovaries of Rhipicephalus microplus partially engorged females. Ovaries from females at different feeding stages were used to detect IGF2. ABSTRACT Gonadulin and insulin‐like growth factor (IGF) are neuropeptides synthesized by the central nervous system (CNS) of arthropods.

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, EarlyView.
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.

Identification and distribution of Rhipicephalus microplus in selected high-cattle density districts in Uganda: signaling future demand for novel tick control approaches

BMC Veterinary Research
Background Rhipicephalus (Boophilus) microplus (Canestrini, 1888), the Asian blue tick, is a highly invasive and adaptable ectoparasite. This tick species has successfully established itself in most regions of the world, with movement of cattle being a ...

Prevalence, Species Diversity, and Risk Factors of Tick Infestation in Cattle From District Peshawar, Pakistan

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
This study documents the prevalence and risk factors of cattle tick infestation in District Peshawar using morphological and molecular identification. Ecological diversity indices reveal moderate tick diversity, while risk factor analysis highlights breed, age, and sex as significant predictors of infestation.

An update on distribution models for Rhipicephalus microplus in West Africa

Geospatial health, 2013
The cattle tick, Rhipicephalus microplus, which reached the West African region approximately 8 years ago, has established viable populations in Côte d'Ivoire and Benin and spread rapidly from the assumed points of introduction. However, existing maps of its distribution range do not agree on the areas at risk, most probably due to suboptimal modelling

Immunoregulation of bovine macrophages by factors in the salivary glands of Rhipicephalus microplus [PDF]

Parasites & Vectors, 2012
Alternative strategies are required to control the southern cattle tick, Rhipicephalus microplus, due to evolving resistance to commercially available acaricides. This invasive ectoparasite is a vector of economically important diseases of cattle such as bovine babesiosis and anaplasmosis.
