Journal ArticleDOI
Development and validation of direct dry loop mediated isothermal amplification for diagnosis of Trypanosoma evansi
Bashir Salim,Bashir Salim,Kyoko Hayashida,Ehab Mossaad,Ryo Nakao,Junya Yamagishi,Chihiro Sugimoto +6 more
TL;DR: This novel dry-LAMP method is more sensitive than conventional PCR, direct (without DNA extraction step), is user friendly and does not require cold chain or highly trained personnel.
Journal ArticleDOI
Genetic diversity among Trypanosoma (Duttonella) vivax strains from Zambia and Ghana, based on cathepsin L-like gene.
Jesca Nakayima,Ryo Nakao,Andy Alhassan,Kyoko Hayashida,Boniface Namangala,Charles Mahama,Kofi Afakye,Chihiro Sugimoto +7 more
TL;DR: This study suggests existence of distinct genetic diversity between T. vivax genotypes from West Africa and Zambia as per their geographical origins.
Journal ArticleDOI
Molecular Detection of Rickettsia africae in Amblyomma variegatum Collected from Sudan
TL;DR: The results demonstrated the wide distribution of Rickettsia africae and/or closely related species across Sudan and highlighted the need for careful consideration of rickettsial infections in patients with nonmalarial febrile illness in this country.
Journal ArticleDOI
Listeria monocytogenes serotype 4b strains replicate in monocytes/macrophages more than the other serotypes
Rie Hasebe,Ryo Nakao,Aiko Ohnuma,Takeshi Yamasaki,Hirofumi Sawa,Shinji Takai,Motohiro Horiuchi +6 more
TL;DR: Histopathological analyses suggest that the NS4b strain replicated more in monocytes/macrophages than the other serotypes, and this may be involved in the pathogenicity of serotype 4b strains, particularly in the dissemination of L. monocytogenes through the host body.
Journal ArticleDOI
Molecular and Serological Evidence of Leishmania Infection in Stray Dogs from Visceral Leishmaniasis-Endemic Areas of Bangladesh.
TL;DR: The hypothesis that stray dogs are an animal reservoir for L. donovani in VL-endemic areas of Bangladesh is supported, as serological and molecular evidence of Leishmania infection is screened and anti-Leishmania antibodies are detected in dog serum samples.
