Pathogenicity of Rickettsia helvetica is relatively unknown. We isolated a spotted fever group rickettsial organism from a patient with subacute meningitis. Nucleotide sequences of the 16S rRNA, ompB, and 17kDa genes identified the isolate as R. helvetica. This organism may be associated with serious infections such as central nervous system disorders.

Article Synopsis
  • Migratory birds can carry ticks and be reservoirs for tick-borne pathogens (TBPs) based on a study conducted on Ixodes ricinus ticks from specific bird species in Poland.
  • A high-throughput microfluidic real-time PCR method was used to detect TBPs in ticks, revealing that 47.41% of the specimens were infected with at least one TBP, with differences in prevalence among the bird species studied.
  • Phylogenetic analysis indicated the circulation of specific haplotypes of TBPs, suggesting that the ticks are widely distributed across various hosts in Central Europe.

Vector-borne diseases pose a significant threat to human and animal health worldwide, with arthropods, including fleas and lice, acting as key vectors for transmitting various pathogens. In Uzbekistan, where millions of domestic dogs coexist with humans, the diversity of vector-borne pathogens carried by ectoparasites remains largely unexplored. This study aimed to investigate the diversity and prevalence of lice and pathogens carried by fleas and lice collected from domestic dogs in Uzbekistan.

Ixodes ricinus is the most important tick vector in central and western Europe and one of the most researched parasites. However, in the published literature on the tick and the pathogens it transmits, conjecture about specific transmission cycles and the clinical significance of certain microbes is not always clearly separated from confirmed facts. This article aims to present up-to-date, evidence-based information about the well-researched human pathogens tick-borne encephalitis virus, louping-ill virus, Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato and several Babesia species, with a focus on their development in the tick, transmission dynamics and the reservoir hosts that support their circulation in the environment.

An infection with the tick-borne has been associated with a broad spectrum of clinical manifestations in humans, but patients are only seldomly reported. Understanding its disease etiology necessitates well-stablished infection models, improving to recognize and diagnose patients with infection and facilitating the development of effective control strategies. In this study, we used C3H/HeN mice as a model to establish infection, achieving a high infection prevalence (89-100 %).
