The dry summer also promotes the spread of tropical ticks here. Researchers warn: the parasites can transmit dangerous diseases.
The discovery of several specimens of a tropical species sign in Germany alerted experts. Experts from the University of Hohenheim and the Institute for Microbiology of the German Armed Forces reported seven copies of the Hyalomma genus this year and are now worried that the leeches might settle in this country, as the University of Hohenheim announced.

Carrier of the Crimean Congo fever
The sign was found on cattle, on horses and on a sheep. One specimen had a dangerous bacterium, a known tick-borne fever. Hyalomma species are considered to be important carriers of, among other things, the Crimean Congo fever, which so far does not occur in Germany.
Until now there were only two separate finds from the tropical drawing species in the years 2015 to 2017. The relatively large animals with the strikingly striped legs appeared this year in the area around Hannover, in Osnabrück and in the Wetterau and were probably introduced by birds. The adult ticks suck blood, especially in large animals. Man is also a potential host.
Dry summer: ticks spread
The scientists attribute the occurrence of hyalommatics in Germany to the hot, dry summer. This tropical species of ticks prefers lower humidity than the ticks commonly found in this country.
This development is not surprising for the experts. Due to global warming, more and more heat-loving signs are to be expected in Germany. Ixodes inopinatus from the Mediterranean, for example, is now distributed to Denmark.
