Giant tick transmits for the first time spotted fever in Germany

For the first time, to have contracted the disease in Germany, a man by the sting of a tropical giant tick of spotted fever. In the tick that had stung the man that has been proven, the relevant pathogens, the University of Hohenheim in Stuttgart.

A horse-holder from the area of Siegen (North Rhine-Westphalia) is at the end of July by a Hyalomma tick with the disease. He was successfully treated with antibiotics.

The number increased significantly

Hyalomma ticks are from the arid and semi – arid Africa and Asia regions. However, in southern Europe it is native and has spread from Spain to Italy to Turkey. Of the local ticks, such as the Common wood tick, one can distinguish them easily: they are up to two centimeters in length to be much larger and have a striking striped legs.

The number of found Hyalomma-increased ticks in Germany in the past few months, and in comparison to the previous year. “In 2019, we have found up to now 50 copies in Germany. Last year there were a total of 35,” said Ute Mackenstedt, Parasitology login at the University of Hohenheim. Of the 2019 found copies of each of the second is according to the Mackenstedt almost the typhus-causing organisms. For the first time tick after the evaluation of the experts in this year Hyalomma-in Germany the winter.

Cause of tick spotted fever, the bacterium Rickettsia aeschlimannii, the a fever infection with headache and muscle aches, and extreme joint pain is leads. Infected feel often as if they would burn. Typical of the disease the rash of the spotted fever the name is. According to the Robert Koch-Institute spotted fever in Germany ticks is very rare. In the past few years, there have been only isolated cases, all the victims have been taken abroad.

“We now know not only ensure that the Hyalomma-stings tick people,” said Mackenstedt. “Now it is clear that a Transmission of tick Typhus by the animals is possible.” Contagion, however, is only possible if the animals have previously sucked at one with the pathogens in the infected organism the blood.

The case of the horse holder from the Sauerland will officially be treated as a suspected case, because it was not possible, the excitation directly on the patient to prove. “The treatment was just standing in the first place,” said Gerhard Dobler, a physician at the Institute for Microbiology of the Bundeswehr in Munich. “But the immediately preceding tick bite, typical symptoms, and especially the detection of the pathogen in the tick to leave no other conclusion, than that it was in the case of ticks-spotted fever.”

“You know when you run around them”

The Hyalomma ticks can also transmit dangerous pathogens, including the Virus that causes the Crimean Congo fever, which may be associated with severe bleeding. In the past year, a total of 18 specimens of Hyalomma were sent-tick from eight Federal States (Bavaria, Baden-Württemberg, Hesse, Rhineland-Palatinate, North Rhine-Westphalia, Brandenburg, Berlin and Schleswig-Holstein) and examined a further 17 ticks had been seen on the basis of images clearly identified as Hyalomma ticks to. None of the tested ticks carried the causative agent of Crimean-Congo Hemorrhagic fever in itself.

But also in Germany, domestic common wood tick is harmless. The transmitted pathogens can cause Lyme disease and TBE (tick-borne encephalitis). While the horned implantation often unnoticed on the body, is to feel the attack of the Hyalomma tick: clear, says expert Mackenstedt: “it is much larger. The notice you when running on them.”
