Gut Bacteriome Modulation in Rhipicephalus microplus Under Biotic Stress From Metarhizium anisopliae and Anaplasma marginale. [PDF]

Environ Microbiol Rep
(A) Ticks exposed to Metarhizium anisopliae and Anaplasma marginale showed enriched SCFA‐producing bacteria, restructured microbial networks and greater robustness under combined stress. Co‐exposure increased functional profiles and KEGG orthologl abundance, with A. marginale exerting a dominant influence. (C) In silico removal of the pathogen revealed

Copy Number Variation-Based Molecular Sexing of <i>Ixodes scapularis</i> and <i>Rhipicephalus microplus</i> Immature Stages Using qPCR and ddPCR Approaches. [PDF]

Ecol Evol
We developed and validated a copy number variation (CNV)‐based molecular method to accurately determine the sex of immature ticks, Ixodes scapularis and Rhipicephalus microplus, which lack morphological sexual dimorphism. Using qPCR and ddPCR assays targeting female‐enriched genes, sex was reliably identified from DNA extracted non‐destructively from a

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region. [PDF]

Pest Manag Sci
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

The Rhipicephalus (Boophilus) microplus Bm86 gene plays a critical role in the fitness of ticks fed on cattle during acute Babesia bovis infection

Parasites & Vectors, 2010
Background Rhipicephalus (Boophilus) microplus is an economically important tick of cattle involved in the transmission of Babesia bovis, the etiological agent of bovine babesiosis. Commercial anti-tick vaccines based on the R.

Silencing of a putative immunophilin gene in the cattle tick Rhipicephalus (Boophilus) microplus increases the infection rate of Babesia bovis in larval progeny

Parasites & Vectors, 2009
Background The cattle tick Rhipicephalus (Boophilus) microplus is involved in the transmission of the protozoan Babesia bovis, the etiological agent of bovine babesiosis. Interactions between ticks and protozoa are poorly understood and the investigation
