Spotted fever group rickettsiae transmitted by Dermacentor ticks and determinants of their spread in Europe

Annals of Agricultural and Environmental Medicine, 2020
Rickettsiae from the spotted fever group, i.e. the etiological agents of tick-borne lymphadenopathy/ Dermacentor -borne necrotic erythema and lymphadenopathy (TIBOLA /DEBONEL) syndrome, are associated with ticks, including Dermacentor marginatus and

Human Infections by Multiple Spotted Fever Group Rickettsiae in Tennessee. [PDF]

Am J Trop Med Hyg, 2016
Rocky Mountain spotted fever is the most common tick-borne disease in Tennessee. However, Rickettsia rickettsii has rarely been isolated from endemic ticks, suggesting rickettsioses may be caused by other species. A total of 56 human serum samples that were serologically positive for exposure to Rickettsia were obtained from commercial laboratories in ...

DEET‐cyclodextrin inclusion complexes for mosquito and tick repellency: Extended repellency time and no zebrafish embryotoxicity

Pest Management Science, EarlyView.
Hydroxypropyl‐β‐cyclodextrin (HPβCD)–N,N‐diethyl‐meta‐toluamide (DEET) complex extended tick repellency to 168 h. Full protection against Aedes aegypti for 7 h with HPβCD‐DEET. HPβCD reduced DEET release and skin retention significantly. No embryotoxicity observed below 325 mg L−1 in zebrafish model.

Spotted fever group Rickettsiae in Ticks from Missouri

Ticks and Tick-borne Diseases, 2018
Tick-borne rickettsioses pose a major health threat among vector-borne infections in Missouri but there are some uncertainties regarding the vector competence and range of tick species, as well as the virulence of certain bacterial species. A survey was developed and implemented to assess local healthcare practitioners' awareness of the prevalence and ...

‘Reservoir dogs’: The emerging zoonotic risk associated with European dog imports to the UK

Veterinary Record, EarlyView.
Abstract Background The movement of dogs from continental Europe to the UK poses a growing public health threat due to the associated risk of disease incursions. Current legislation is insufficient to address the risks and pre‐import control measures are focused only on rabies virus and the fox tapeworm Echinococcus multilocularis. Methods We conducted
