The two most common species of tick: the Ixodes Ricinus – the common tick which does not have eyes is mainly found in Turkey-oak forests. It lives in bushy, damp places. It falls off the back of leaves or climbs onto the host from the height of a maximum of 1.5 m. It serves as the vector of Lyme-disease: the Borrelia burgdorferi causes disease in humans and dogs that have the same name. The Dermacentor reticultus – the dog tick has eyes. It likes living in lawns and climbs on the host from the grass. When it bites, it spreads the pathogen of the Babesiosois with its saliva. Dogs can have a number of symptoms: losing weight, the loss of appetite, swollen lymphatic glands and swollen joints. The transfer of the pathogens takes 24 hours. The meningitis – tick encephalitis is a pathogen that may cause infections in humans. Dogs are less susceptible for the virus.
Apart from ticks, mosquitoes may also spread pathogens with their saliva!!!
