[Characteristics of acquired resistance of lambs to mature ticks Hyalomma asiaticum asiaticum (experimental studies)].
A new method was employed for studies of parasite-host relationships between ixodid ticks and their hosts. It has been established that ixodid ticks are able to desensibilize the reactive sensibility of the host and to satiate themselves without unhibiting the latter. Every day and long parasitism of the ticks on cattle (in nature) and increasing doses of secretion of the ticks' saliva (sensibilizer) lead apparently to the weakening of the host's organism (desensitization). However, under laboratory conditions in hosts a resistence to bites of ixodid ticks can appear.
