Functional changes of cattle in ixodiasis disease.

Ixodic ticks are temporary parasites. They are on the host during bloodsucking only. The female tick needs from 6 to 8 days for full saturation, while the body size increases up to 120 times. One female tick drinks up to 4 ml of blood. The article describes the functional disorders of the body of cattle with experimentally modeled Ixodiasis by Dermacentor reticulatus ticks. The tick-borne Ixodiasis or Toxicosis of cattle is isolated into a separate nosological group. Young animals are especially vulnerable to the mass attack of ixodic ticks. During the summer season animals can lose up to 5 liters of blood in strong attack areas and the average daily loss of milk reaches 4.8 – 10 G per 1 kg body weight. The results of functional changes (body temperature, pulse, number of heart contractions, respiratory movements) were protocoled. In 87% of cases the strong inflammatory reactions were not found at the attachment sites of ixodic ticks, however, 13% of animals showed signs of inflammation: slight swelling at the bite sites, redness and discharge of blood and lymph droplets, which drying out formed crusts. Based on the experiment conducted it was found that a mass attack (50 female ixodic ticks and more) on cattle causes Ixodiasis disease, that manifests itself by significant functional changes during all days of observation.
