Antibody Seroprevalence to Spotted Fever Group Rickettsiae in Miraflores, Colombia: A Cross-Sectional Study in Humans and Dogs
Am J Trop Med Hyg. 2024 Apr 9:tpmd230593. doi: 10.4269/ajtmh.23-0593. Online ahead of print.ABSTRACTTick-borne disease burdens are increasing globally, impacting mostly rural and vulnerable communities. Among the most important emerging tick-borne pathogens are the Rickettsia species within the spotted fever group (SFGR) because of their genetic diversity and high lethality rate. Colombia is highly affected by SFGR despite not being reportable diseases; thus, research and clinical management are neglected. Although some departments have demonstrated high seroprevalence rates, in others, such as Boyacá Department, seroprev...

Viruses, Vol. 16, Pages 576: High-Throughput Sequencing Reveals Three Rhabdoviruses Persisting in the IRE/CTVM19 Cell Line
lina G. Karganova
Cell cultures derived from ticks have become a commonly used tool for the isolation and study of tick-borne pathogens and tick biology. The IRE/CTVM19 cell line, originating from embryos of Ixodes ricinus, is one such line. Previously, reovirus-like particles, as well as sequences with similarity to rhabdoviruses and iflaviruses, were detected in the IRE/CTVM19 cell line, suggesting the presence of multiple persisting viruses. Subsequently, the full genome of an IRE/CTVM19-associated rhabdovirus was recovered from a cell culture during the isolation of the Alongshan virus. In the current work, we used...

A Case of Tick-borne Yezo Virus Infection: Concurrent Detection in the Patient and Tick
The Yezo virus (YEZV) is a new nairovirus species identified in two presumed cases of tick-borne disease in Hokkaido, Japan, in 2019 and 2020 [1]. A retrospective examination of serum samples from 248 patients with suspected tick-borne disease in Hokkaido since 2014 identified YEZV RNA in five individuals [1]. Furthermore, a recent study involving 402 patients with tick bites in Northeastern China detected YEZV RNA in a single patient [2]. Infections attributable to tick-borne nairoviruses can cause severe symptoms in humans and are emerging as a global public health concern. (Source: International Journal of Infectious Diseases)

Cervids as Sentinels for Rickettsia spp. in Portugal
Acta Trop. 2024 Mar 31;254:107202. doi: 10.1016/j.actatropica.2024.107202. Online ahead of print.ABSTRACTCervids are highly exposed to ticks, however, their role in the life cycle of these rickettsiae has not been fully elucidated. Given the expanding distribution and growing population of deer species in Portugal, coupled with their direct and indirect interactions with humans during hunting, it becomes crucial to explore their role as sentinels and potential reservoirs of Rickettsia. The present investigation aimed to detect and evaluate exposure to Rickettsia in free-living deer from Portugal. Blood samples (n = 77) wer...

Detection of Anaplasma spp. and Ehrlichia spp. in dogs from a veterinary teaching hospital in Italy: a retrospective study 2012 –2020
AbstractAnaplasma phagocytophilum,Anaplasma platys andEhrlichia canis, responsible of diseases in dogs, are tick-borne pathogens with a proven or potential zoonotic role that have shown increasing prevalence worldwide. The aims of this retrospective study were to assess the frequency ofAnaplasma spp. andEhrlichia spp. exposure in dogs tested in a veterinary teaching hospital in Italy over a 9-year period, to compare the performance of the diagnostic tests used, to evaluate correlations with clinical data, and to genetically analyse the identified bacteria. During the study period, 1322 dogs tested by at least one of the ra...
