Variation in Small Mammal Species Composition and the Occurrence of Parasitic Mites in Two Landscapes in a Scrub Typhus Endemic Region of Western Yunnan Province, China

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Yunnan Province, the most serious scrub typhus endemic areas in China, provides abundant ecological resources that sustain parasite and host populations. The distribution of vector‐borne diseases is driven by interactions between hosts, vectors and the environment, revealing critical ecological dynamics.

tRNA signatures reveal polyphyletic origins of streamlined SAR11 genomes among the alphaproteobacteria [PDF]

open access: yes, 2013
Phylogenomic analyses are subject to bias from compositional convergence and noise from horizontal gene transfer (HGT). Compositional convergence is a likely cause of controversy regarding phylogeny of the SAR11 group of Alphaproteobacteria that have ...

The Endosymbiont Consortia of Two Cixiidae Planthoppers Reveal an Ancient Symbiosis With ‘Candidatus Mirabilia Symbiotica’

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Many insects harbour ancient beneficial endosymbionts that produce essential nutrients. Two planthopper species from the Cixiidae family harbour different tripartite endosymbiont consortia, including a previously unknown and likely ancient Gammaproteobacterium in addition to Karelsulcia and Vidania.

Current and Future Projection of Scrub Typhus Risk Related to Land Use Change in China

open access: yesGeoHealth, Volume 9, Issue 9, September 2025.
Abstract The widespread concern surrounding the enhanced spillover risk of infectious diseases due to dramatic global land use changes has sparked significant discussion. However, the specific implications of these changes on scrub typhus, a vector‐borne infectious disease facing increasing incidence and substantial expansion, remain unclear.

Analysis of Prevalent Orientia tsutsugamushi in Aichi Prefecture

open access: yesJournal of the Japanese Association for Infectious Diseases, 1999
Orientia tsutsugamushi was isolated from one of 8 patients' sera in Aichi Prefecture, and was identified to have the same antigenicity with the KN-2 strain (KN-2 like) based on the reactivity with 13 types of strain-specific or cross-reactive monoclonal antibodies to Karp, Gilliam, and Kato strains.
