Molecular evidence confirms occurrence of Rhipicephalus microplus Clade A in Kenya and sub-Saharan Africa

Parasites & Vectors, 2020
The tick vector Rhipicephalus microplus which transmits Babesia spp. and rickettsial pathogens has not been reported in Kenya since 1998. More recently, the pathogenic Babesia bovis has been detected in cattle blood DNA. The status of R.

A new mutation in the octopamine receptor associated with amitraz resistance in Varroa destructor

Pest Management Science, Volume 81, Issue 1, Page 308-315, January 2025.
A new mutation (F290L) in the octopamine β2 receptor of Varroa destructor mites from Spanish apiaries has been identified. The L290 allele frequency increased with repeated amitraz treatments. Mutant mites showed lower susceptibility to amitraz. Abstract BACKGROUND The acaricide amitraz is now used intensively in many regions to control the honey bee ...

First Molecular Typing of Tick‐Derived Coxiella burnetii From Wildlife in South Korea: Surveillance and Genetic Characterization

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Q fever, caused by Coxiella burnetii, is a widespread zoonosis characterized by environmental persistence and a broad host range. Wildlife and their associated ticks are increasingly recognized as crucial elements in the ecology of this pathogen; however, molecular data from these reservoirs in South Korea remain scarce.

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

Molecular Profiling of Ticks and Associated Pathogens: First Report of Rickettsia sibirica, Rickettsia slovaca, and Babesia microti in Ticks From Pakistan

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Global distribution of ticks and their associated tick‐borne pathogens (TBPs) presents substantial health concerns for both humans and animals. The present study aimed to investigate the distribution, morpho‐molecular identification, and associated TBPs of diverse tick species collected from Khyber Pakhtunkhwa and Punjab provinces of Pakistan ...

Target‐based discovery of antagonists of the tick (Rhipicephalus microplus) kinin receptor identifies small molecules that inhibit midgut contractions

Pest Management Science, Volume 80, Issue 10, Page 5168-5179, October 2024.
The screen of small molecule analogs identifies new non‐cytotoxic antagonists of the tick kinin receptor with inhibitory myotropic activity on the midgut. Abstract BACKGROUND A GPCR (G protein‐coupled receptor) target‐based approach was applied to identify antagonists of the arthropod‐specific tick kinin receptor. These small molecules were expected to
