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. [PDF]

Parasite Immunol
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.

In Vitro Acaricidal Activity of <i>Croton macrostachyus</i> Leaf and <i>Ricinus communis</i> Seed Extracts Against Cattle-Infesting Ticks (<i>Rhipicephalus</i> spp. and <i>Amblyomma</i> spp.). [PDF]

Vet Med Int
Ticks are major ectoparasites of cattle and vectors of zoonotic and livestock diseases. Reliance on synthetic acaricides like diazinon has led to environmental concerns and rising resistance, prompting the search for ecofriendly alternatives. This in vitro study evaluated the acaricidal activity of Croton macrostachyus, Ricinus communis, and their ...
