  • A classification framework for Bacillus anthracis defined by global genomic structure 
    Bruce, Spencer A; Schiraldi, Nicholas J; Kamath, Pauline L.; Easterday, William Ryan; Turner, Wendy C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Bacillus anthracis , the causative agent of anthrax, is a considerable global health threat affecting wildlife, livestock, and the general public. In this study, whole‐genome sequence analysis of over 350 B. anthracis ...
  • Coalescence modeling of intrainfection Bacillus anthracis populations allows estimation of infection parameters in wild populations 
    Easterday, William Ryan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Bacillus anthracis, the etiological agent of anthrax, is a well-established model organism. For B. anthracis and most other infectious diseases, knowledge regarding transmission and infection parameters in natural systems, ...
  • Contrasting emergence of Lyme disease across ecosystems 
    Mysterud, Atle; Easterday, William Ryan; Stigum, Vetle Malmer; Aas, Anders Bjørnsgard; Meisingset, Erling L.; Viljugrein, Hildegunn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Global environmental changes are causing Lyme disease to emerge in Europe. The life cycle of Ixodes ricinus, the tick vector of Lyme disease, involves an ontogenetic niche shift, from the larval and nymphal stages utilizing ...
  • Evolutionary selection of biofilm-mediated extended phenotypes in Yersinia pestis in response to a fluctuating environment 
    Cui, Yujun; Schmid, Boris Valentijn; Cao, Hanli; Dai, Xiang; Du, Zhongmin; Easterday, William Ryan; Fang, Haihong; Guo, Chenying; Huang, Shanqian; Liu, Wanbing; Qi, Zhizhen; Song, Yajun; Tian, Huaiyu; Wang, Min; Wu, Yarong; Xu, Bing; Yang, Chao; Yang, Jing; Yang, Xianwei; Zhang, Qingwen; Jakobsen, Kjetill Sigurd; Zhang, Yujiang; Stenseth, Nils Christian; Yang, Ruifu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Yersinia pestis is transmitted from fleas to rodents when the bacterium develops an extensive biofilm in the foregut of a flea, starving it into a feeding frenzy, or, alternatively, during a brief period directly after ...
  • Individual heterogeneity in ixodid tick infestation and prevalence of Borrelia burgdorferi sensu lato in a northern community of small mammalian hosts 
    Lindsø, Lars; Anders, Jason Lee; Viljugrein, Hildegunn; Herland, Anders; Stigum, Vetle Malmer; Easterday, William Ryan; Mysterud, Atle (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Heterogeneous aggregation of parasites between individual hosts is common and regarded as an important factor in understanding transmission dynamics of vector-borne diseases. Lyme disease is vectored by generalist ...
  • Spatial and seasonal variation in the prevalence of Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato in questing Ixodes ricinus ticks in Norway 
    Mysterud, Atle; Easterday, William Ryan; Qviller, Lars; Viljugrein, Hildegunn; Ytrehus, Bjørnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Background. Understanding the variation in prevalence of Borrelia burgdorferi sensu lato (Lyme Borreliosis Spirochaetes, LBS) and Anaplasma phagocytophilum (causing tick-borne fever in ruminants and human granulocytic ...
  • The Genome of the Great Gerbil Reveals Species-Specific Duplication of an MHCII Gene 
    Nilsson, Pernille; Solbakken, Monica Hongrø; Schmid, Boris Valentijn; Orr, Russell; Lv, Ruichen; Cui, Yujun; Song, Yajun; Zhang, Yujiang; Baalsrud, Helle Tessand; Tørresen, Ole K.; Stenseth, Nils Christian; Yang, Ruifu; Jakobsen, Kjetill Sigurd; Easterday, William Ryan; Jentoft, Sissel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract The great gerbil (Rhombomys opimus) is a social rodent living in permanent, complex burrow systems distributed throughout Central Asia, where it serves as the main host of several important vector-borne ...
