Microbial community structure reveals instability of nutritional symbiosis during the evolutionary radiation of Amblyomma ticks

Molecular Ecology, 2020
Mutualistic interactions with microbes have facilitated the adaptation of major eukaryotic lineages to restricted diet niches. Hence, ticks with their strictly blood‐feeding lifestyle are associated with intracellular bacterial symbionts through an ...

Experimental Infection of Amblyomma americanum (Acari: Ixodidae) With Bourbon Virus (Orthomyxoviridae: Thogotovirus).

Journal of medical entomology, 2020
Following the recent discovery of Bourbon virus (BRBV) as a human pathogen, and the isolation of the virus from Amblyomma americanum (L.) collected near the location of a fatal human case, we undertook a series of experiments to assess the laboratory ...

Notas de Ixodologia: IV - considerações sôbre a nomeclatura de algumas espécies do gênero Amblyomma do Brasil e países limítrofes (Acari: Ixodidae)

Memorias do Instituto Oswaldo Cruz, 1952
An attempt is made to clear the nomenclature of some netropical species of the genus Amblyomma. Amblyomma myrmecophagium Schulze, 1933 and Amblyomma brasiliense guyanense Floch et Abonnenc, 1933, are synonyms of Amblyoma scalpturatum Neumann, 1906 ...

Novel Ehrlichia Strain Infecting Cattle Tick Amblyomma neumanni, Argentina, 2018

Emerging Infectious Diseases, 2020
In 2018, we detected a novel Ehrlichia strain infecting Amblyomma neumanni ticks in Argentina. The novel strain is phylogenetically related to the ruminant pathogen E. ruminantium and represents a potential risk for veterinary and public health because A.

Sympatry of Amblyomma eburneum and Amblyomma variegatum on African buffaloes and prevalence of pathogens in ticks

Ticks and Tick-Borne Diseases, 2023
The Amblyomma genus is represented on the African continent by 24 species, out of which 17 are known to occur in different ecological niches of southern Africa. Amblyomma, known for their aggressive hunting behaviour and aptitude as pathogen vectors, are

Characterization of the complete mitochondrial genome of Amblyomma ovale, comparative analyses and phylogenetic considerations

Experimental & applied acarology, 2020
In this study, we sequenced two complete mitochondrial genomes of Amblyomma ovale, a tick of public health importance. Sequencing two distinct individuals, the resulting mitochondrial genomes were 14,756 and 14,760 bp in length and maintained the same ...
