In regions of temperate and tropical climates, ticks are the most important transmitters of causes of diseases of all Arthropoda. They have an important role in human and veterinary medicine both through direct effects, and by transmitting the cause of the disease from animals to humans. Among the causes of diseases transmitted by ticks are viruses, bacteria, fungi and Protozoa. Ticks were also found to carry helminths in some cases. The direct effects of ticks are manifested as mechanical damage, anaemia, paralysis and toxicosis. These effects can be united with secundary infections by bacteria or fungi, or the occurrence of myasis. Many diseases transmitted by ticks are characterized by a high degree of endemic stability. The stability can be disrupted by the introduction of suspect unadapted hosts, which is followed by an increase in the number of diseases primarily in newly-arrived animals, with a resulting change in the epidemiological situation.
