In this study, samples from the nests of seabirds and surrounding soil were collected to investigate Ornithodoros spp. from 9 uninhabited islands in the western, eastern, and southern parts of Korea from April 2017 to October 2018. The islands are known as the breeding places of migratory and resident birds. Ticks were collected from soil and nest material of seabirds using a Tullgren funnel and identified using 16S rRNA and the cytochrome c oxidase 1 gene (COI), and host animals of soft ticks were identified using the mitochondrial DNA cytochrome b gene by a polymerase chain reaction. In the sequence identity of the 16S r...

Martins, Marcelo B. LabrunaAbstractA new argasid (Argasidae) tick is herein described based on morphology and molecular data obtained from larvae parasitizing Octodon degus and from ticks collected inside burrows in northern Chile. Unfed laboratory-reared larvae were mounted in slides for morphometrical and morphological analyses. Larvae of Ornithodoros octodontus n. sp. share morphological tr...

The I. apronophorus sequences demonstrated the highest nucleotide and haplotype diversity for both m...

The objective of this study was to elucidate the biology of O. fonsecai from Nobres, and to report autogeny in this tick population. Along three laboratory generations was observed molting of first nymphal instar to the second instar without feeding, a typical behavior of species included in the subgenus Alectorobius. The first generation (F1) presented five nymphal instars (N1 to N5), and most of adults emerged through molting of N5. The last nymphal instar of second generation (F2) was N4, but most of adults emerged from N3. In the third generation (F3) the last nymphal instar was N5, with most of the adults emerging fro...

This report is the first to describe CytB marker sequences of the studied species, and the first to describe COX1 marker sequences of H. aegyptium, H. excavatum, H. impeltatum and H. turanicum. The information obtained in this study may therefore be useful for future combined morphological-molecular Hyalomma characterization.

Conclusion The African continent is home to diverse populations of livestock breeds that possess extremely valuable genetic materials but which are not utilized effectively to support economic development or to meet up with increasing demand. Owing to the rich genetic resources and availability of advanced breeding technologies, genomic breeding can be used to speedup livestock development on the continent of Africa. However, the promise and usefulness of genomic tools (especially genomic selection), which have supported livestock gains in many Western countries are yet to be implemented in most of Africa; the major const...

SabetiBabesia microti is tick-borne disease that is an emerging threat to public health due to increasing prevalence and expanding geographic range. Detection and constant surveillance of babesiosis is imperative for predicting pathogen expansion. Leveraging our whole genome sequence (WGS) analyses ofB.microti, we developed a single nucleotide polymorphism (SNP)-based high resolution melt (HRM) surveillance tool. We developed our HRM assay using available sequence data and identified 775 SNPs. From these candidate SNPs, we develo...

Publication date: Available online 26 February 2019Source: Ticks and Tick-borne DiseasesAuthor(s): Delaney Burnard, Renfu ShaoAbstractTicks rank second in the world as vectors of disease so it is paramount we understand their biology in order to advance disease control. Mitochondrial genome sequences of tick species have been used increasingly to resolve relationships of closely related species, correct taxonomic discrepancies and to understand intraspecific variation. Despite this, our understanding and advances in tick biology are obstructed by the lack of complete mitochondrial genomes available for most species, partic...
