Situação atual da resistência do carrapato-do-boi Rhipicephalus (Boophilus) microplus aos acaricidas no Brasil. [PDF]

, 2011
Rhipicephalus microplus é o principal ectoparasita hematófago dos bovinos, presente nas diversas regiões do país. É causador de enormes perdas econômicas pela espoliação que causa ao hospedeiro, além de ser transmissor da tristeza parasitária bovina.

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

Entomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 285-295, March 2026.
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.

Expression profile of Rhipicephalus microplus vitellogenin receptor during oogenesis

Ticks and Tick-borne Diseases, 2018
The vitellogenin receptor (VgR), which belongs to the low-density lipoprotein receptors (LDLR) family, regulates the absorption of yolk protein accumulated in developing oocytes during oogenesis. In the present study, the full sequence of Rhipicephalus microplus VgR (RmVgR) and the partial sequence of Rhipicephalus appendiculatus VgR (RaVgR) ORF were ...

Functional and Immunological Relevance of Anaplasma marginale Major Surface Protein 1a Sequence and Structural Analysis. [PDF]

, 2013
Bovine anaplasmosis is caused by cattle infection with the tick-borne bacterium, Anaplasma marginale. The major surface protein 1a (MSP1a) has been used as a genetic marker for identifying A.

Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune‐Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis

Parasite Immunology, Volume 48, Issue 3, March 2026.
ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.
