Canine Spotted Fever Group Rickettsial Seroprevalence as an Indicator for Human Rocky Mountain Spotted Fever Case Rates in Arizona, USA

Zoonoses and Public Health, Volume 72, Issue 8, Page 697-705, December 2025.
ABSTRACT Introduction Rocky Mountain spotted fever (RMSF), a rapidly progressing febrile disease caused by the bacterium Rickettsia rickettsii, is the deadliest tick‐borne disease in the world. Human infection initially results in non‐specific symptoms and, if untreated, can result in death in up to 35% of cases.

Harnessing 50 years of tick population genetics: Choosing the right molecular tool for contemporary research

Journal of Animal Ecology, Volume 94, Issue 11, Page 2159-2177, November 2025.
Population genetics reveals how ticks interact with hosts, microbiomes and environments. This review guides researchers in choosing the best tool for the job, weighing cost, resolution, reproducibility and throughput to study tick population structure. Abstract Ticks are ectoparasites of major medical, veterinary and ecological importance, transmitting

CD8+ T cells against extracellular pathogens: more than just a cytotoxic cell

Immunology &Cell Biology, Volume 103, Issue 10, Page 957-965, November-December 2025.
CD8+ T cells can induce immunopathology or disease tolerance and resistance in infections caused by extracellular pathogens. The secretion of IFNγ by CD8+ T cells can collaborate with IL‐17 for the elimination of extracellular pathogens. In addition, CD8+ T cells can restrict immunopathology through the elimination of APCs.
