The cattle tick Rhipicephalus (Boophilus) microplus is known to transmit both anaplasmosis and babesiosis, two diseases that have important impacts on animal health. To delimit areas of climatic suita...

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.

Background Kyasanur forest disease virus (KFDV) is a tick-borne flavivirus causing debilitating and potentially fatal disease in people in the Western Ghats region of India. The transmission cycle is ...

Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV) is a deadly tick-borne virus and a growing global health threat. In this study, Petit et al. used a multi-omics approach on SFTSV-infected tic...

Researchers at Hainan University showed that vaccinating rabbits with recombinant Mucin-6 from the tick Rhipicephalus linnaei elicited high antibody titers and significantly reduced tick engorgement

Background The brown dog tick, Rhipicephalus sanguineus sensu lato (Rh. sanguineus s.l.), is an important vector of Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever (RMSF), i...

The study, published in Nature Communications, provides the most detailed picture yet of how cells from the tick species Rhipicephalus microplus respond to infection with severe fever with thrombocytopenia syndrome virus (SFTSV).SFTSV can cause high fever, internal bleeding and death in humans and currently has no licensed treatment or vaccine.

Rhipicephalus microplus is a major ectoparasite of cattle, significantly impacting animal health and livestock productivity in tropical and subtropical regions. This study investigated the current status and predicted the future distribution of R. microplus in northern Vietnam under climate change scenarios. Field surveys were conducted across 25 provinces from 2022 to 2024, collecting data on tick infestation by province, season and host species. Statistical analyses were performed by...

Tick-borne pathogens, transmitted by ticks, infect humans and animals worldwide. The brown dog tick, Rhipicephalus sanguineus sensu lato, is a significant vector of a number of pathogens, including Ehrlichia canis, Rickettsia and Anaplasma species. In Ghana, there is limited information on the pathogens carried by Rh. sanguineus s.l. As such, Rh. sanguineus ticks taken from domestic dogs in Kumasi were screened for tick-borne pathogens, including Coxiella burnetii, Rickettsia, Babesia, Theileria, Anaplasma, Ehrlichia and Hepatozoon species. A total of 204 ticks collected from 56 infested dogs were morphologically identified as Rh. sanguineus s.l. From the 88 pools screened, 36 (40.9%) were positive for pathogen DNA. The pathogens identified were Rickettsia africae (5 pools), Ehrlichia canis (10 pools) and uncultured Anaplasma sp. (21 pools) with maximum likelihood estimates as 2.48% (95% CI: 0.93, 5.38%), 5.22% (95% CI: 2.69, 9.15%) and 11.20% (95% CI: 7.32, 16.29%), respectively. There was no association between the detection of a pathogen and the tick sex or dog breed, age or sex. This study provides important baseline data on the circulation of tick-borne pathogens in Rh. sanguineus s.l. ticks in Kumasi, with implications for both veterinary and human health. The presence of uncultured Anaplasma sp. suggests a wider diversity of tick-borne bacteria with unknown pathogenicity. There is a need for integrated tick control, improved diagnosis and additional epidemiological studies to mitigate the impact of tick-borne diseases in Ghana.
