November 2024
Article Synopsis
- Tularemia, caused by the bacterium Francisella tularensis, poses a significant threat to human health but lacks extensive data on its distribution in blood-feeding arthropods.
- A study conducted in the Břeclav district in 2022 screened various hematophagous vectors, including ticks, mosquitoes, and blackflies, to check for the presence of this bacterium.
- The results revealed only two positive samples for F. tularensis subsp. holarctica, both from the tick species Dermacentor reticulatus, while no presence was found in mosquitoes or blackflies.
Brucella microti and Rodent-Borne Brucellosis: A Neglected Public Health Threat.
Zoonoses Public Health
October 2024
Brucellosis is one of the most important zoonoses worldwide, primarily affecting livestock but also posing a serious threat to public health. The major Brucella species are known to cause a feverish disease in humans with various clinical signs. These classical Brucella species are (re-)emerging, but also novel strains and species, some of them transmitted from rodents, can be associated with human infections.

- The Cimicidae family consists of blood-feeding ectoparasites that primarily target warm-blooded animals, particularly swallow birds and their nestlings.
- Oeciacus hirundinis, a type of house martin bug, has not been known to transmit zoonotic pathogens, but its potential involvement in the spread of arboviruses in Europe is uncertain.
- In a study conducted in southern Moravia, Czech Republic, researchers detected Usutu virus (USUV) RNA in O. hirundinis, suggesting it might play a role in the virus's overwintering in Europe despite the absence of swallows during winter.
Article Synopsis
- * It presents a detailed clinical description and laboratory findings that support the diagnosis, including the link between the infection and a bite from an infected rodent.
- * Lastly, the authors emphasize the need for monitoring wildlife for not just known diseases but also emerging bacterial pathogens like the one discussed.
Ťahyňa virus-A widespread, but neglected mosquito-borne virus in Europe.
Zoonoses Public Health
August 2023
Ťahyňa virus (TAHV) is an orthobunyavirus and was the first arbovirus isolated from mosquitoes in Europe and is associated with floodplain areas as a characteristic biotope, hares as reservoir hosts and the mammal-feeding mosquitoes Aedes vexans as the main vector. The disease caused by TAHV ("Valtice fever") was detected in people with acute flu-like illness in the 1960s, and later the medical significance of TAHV became the subject of many studies. Although TAHV infections are widespread, the prevalence and number of actual cases, clinical manifestations in humans and animals and the ecology of transmission by mosquitoes and their vertebrate hosts are rarely reported.
