The diagnosis and vector potential of Ornithonyssus bacoti tropical rat mites in northern Europe.

The mesostigmatid tropical rat mite, Ornithonyssus bacoti, is an important cause of disease in small rodents, and of gamasoidosis in humans when they come into contact with infestations. Most reports of O. bacoti infestations are from warmer parts of the Americas, southern Europe and Asia; and infection has only rarely been recorded in northern Europe.

Annual number of generations and biology of non-parasitic phase of Rhipicephalus microplus in irrigated and non-irrigated pasture in a tropical region.

This study aimed to verify the number of R. microplus annual generations in irrigated and non-irrigated pastures compared to the constant ideal environment. It also sought to evaluate the biology of the non-parasitic phase of this tick for each generation in these different areas of pasture; assess the larvae population dynamics in the pasture of each tick generation, and evaluate the R.

Ticks parasitizing cold-blooded animals from three different Brazilian biomes; with note for males of Amblyomma rotundatum.

Ticks parasitize a wide variety of wild animals, including amphibians and reptiles. In addition to the possibility of microorganism transmission to these hosts, ticks can also cause severe bleeding, and high parasitism can lead to death. Therefore, knowing the diversity of ticks parasitizing amphibians and reptiles is important for conservation and preservation measures for these vertebrates.

Brazil's battle against Rhipicephalus (Boophilus) microplus ticks: current strategies and future directions.

Ticks are parasitic arthropods that cause significant economic losses to livestock production worldwide. Although Rhipicephalus (Boophilus) microplus, the cattle tick, occurs throughout the Brazilian territory, there is no official program to control this tick, which is the vector of tick fever pathogens. We address the situation of R.

and Assessment of Dimeric Flavonoids (Brachydins) on Glutathione S-transferase.

Introduction: , an important cattle ectoparasite, is responsible for a substantial negative impact on the economy due to productivity loss. The emergence of resistance to widely used commercial acaricides has sparked efforts to explore alternative products for tick control.

Methods: To address this challenge, innovative solutions targeting essential tick enzymes, like glutathione S-transferase (GST), have gained attention.
