A Coxiella mutualist symbiont is essential to the development of Rhipicephalus microplus [PDF]

Scientific Reports, 2017
AbstractThe cattle tickRhipicephalus microplusis a hematophagous ectoparasite that causes important economic losses in livestock. Different species of ticks harbor a symbiont bacterium of the genusCoxiella. It was showed that aCoxiellaendosymbiont fromR.microplus(CERM) is a vertically transmitted mutualist symbiont, comprising 98% of the 16S rRNA ...

A revision of two distinct species of Rhipicephalus: R. microplus and R. australis

Ciência Rural, 2016
: Rhipicephalus ( Boophilus ) species are monoxenous ticks with seasonal distribution in tropical and subtropical regions. For many years, Rhipicephalus microplus was considered as a single species; however, further analysis split these ticks into two ...

Evaluation in vitro of the infection times of engorged females of Rhipicephalus (Boophilus) microplus by the entomopathogenic nematode Steinernema glaseri CCA strain Avaliação in vitro dos tempos de infecção de fêmeas ingurgitadas de Rhipicephalus (Boophilus) microplus pelo nematoide entomopatogênico Steinernema glaseri estirpe CCA

Ciência Rural, 2010
Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes

Effects of destruxin A on Rhipicephalus (Boophilus) microplus ticks (Acari: Ixodidae) Efeitos da destruxina A no carrapato Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)

Revista Brasileira de Parasitologia Veterinária, 2011
This study evaluated the effects of destruxin A on Rhipicephalus (Boophilus) microplus females, since this toxin is one of the likely causes of high mortality induced by the entomopathogenic fungus Metarhizium anisopliae in arthropods.

Immunoprotective potential of a Rhipicephalus (Boophilus) microplus metalloprotease

Veterinary Parasitology, 2015
Ticks have serious impacts on animal and human health, causing significant economic losses in cattle breeding. Besides damage due to the hematophagous behavior, they transmit several pathogens. Low cost and environmental safety have made vaccines a promising alternative control method against tick infestation.
