Occurrence of Francicella tularensis subsp. holarctica in haematophagous arthropods in the Breclav district in 2022

Original language description

Tularemia is a zoonosis caused by Francisella tularensis, a gram-negative aerobic bacterium belonging to the class of Gammaproteobacteria and the family Francisellaceae. Despite its undeniable importance for human health, there is little data on the current distribution of F. tularensis in various hematophagous arthropods. The aim of this study was to perform a mass molecular screening of different possible hematophagous vectors: ticks (4348 ticks of the species Ixodes ricinus, Dermacentor reticulatus, and Haemaphysalis concinna), mosquitoes (4100 specimens of Aedes vexans), and blackflies (6900 specimens of the Simulium spp.) for the presence of F. tularensis in the Břeclav district in 2022. Only two specimens were positive for the specific DNA of Francisella tularensis subsp. holarctica. Both samples originated from D. reticulatus, one collected from infested roe deer and the other included in a pooled sample (n = 10). Both positive samples were sequenced, and the presence of F. tularensis subsp. holarctica was confirmed. In addition, the absence of F. tularensis in mosquitoes and black flies was documented.
