Journal ArticleDOI
Revisiting the taxonomy and evolution of pathogenicity of the genus Leptospira through the prism of genomics
Antony T. Vincent,Olivier Schiettekatte,Olivier Schiettekatte,Cyrille Goarant,Vasantha Kumari Neela,Eve Bernet,Eve Bernet,Roman Thibeaux,Nabilah Ismail,Mohd Khairul Nizam Mohd Khalid,Fairuz Amran,Toshiyuki Masuzawa,Ryo Nakao,Anissa Amara Korba,Pascale Bourhy,Frédéric J. Veyrier,Mathieu Picardeau +16 more
TL;DR: A massive species diversity is uncovered and a novel subclade in environmental samples collected worldwide is revealed and the classification of species in the genus Leptospira is redefined.
Journal ArticleDOI
Potential Spatial Distribution of the Newly Introduced Long-horned Tick, Haemaphysalis longicornis in North America
Ram K. Raghavan,Stephen C. Barker,Marlon E. Cobos,Dayana Barker,Ernest J.M. Teo,Desmond H. Foley,Ryo Nakao,Kevin Lawrence,Allen C. G. Heath,A. T. Peterson +9 more
TL;DR: The North American distributional potential of the recently invaded tick, Haemaphysalis longicornis, was estimated using occurrence data from its geographic range in other parts of the world and relevant climatic data sets to indicate a broad potential distribution, but restricted to three sectors.
Journal ArticleDOI
Microbial population analysis of the salivary glands of ticks; a possible strategy for the surveillance of bacterial pathogens.
TL;DR: The microbial populations in tick salivary glands were different between tick species, indicating that host specificities may play an important role in determining the microbial complement.
Journal ArticleDOI
A novel approach, based on BLSOMs (Batch Learning Self-Organizing Maps), to the microbiome analysis of ticks
Ryo Nakao,Takashi Abe,Takashi Abe,Ard M. Nijhof,Seigo Yamamoto,Frans Jongejan,Frans Jongejan,Toshimichi Ikemura,Chihiro Sugimoto +8 more
TL;DR: Efforts to construct a database of tick microbes may lead to the ability to predict emerging tick-borne diseases, and a comprehensive understanding of tick microbiomes will be useful for understanding tick biology, including vector competency and interactions with pathogens and symbionts.
Journal ArticleDOI
Development of Loop-Mediated Isothermal Amplification (LAMP) Assays for Rapid Detection of Ehrlichia ruminantium
Ryo Nakao,Ellen Y. Stromdahl,Joseph W Magona,Bonto Faburay,Boniface Namangala,Imna I. Malele,Noboru Inoue,Dirk Geysen,Kiichi Kajino,Frans Jongejan,Frans Jongejan,Chihiro Sugimoto +11 more
TL;DR: Due to its simplicity and specificity, LAMP has the potential for use in resource-poor settings and also for active screening of E. ruminantium in both heartwater-endemic areas and regions that are at risk of contracting the disease.
