1. To study the distribution and species composition of ixodid ticks in the steppe, semi-desert and desert zones of West Kazakhstan region. Ticks found on cattle will be identified to species. The distribution of ticks in various natural zones of West Kazakhstan region has been determined, which is necessary for the development of preventive measures.

2. To determine seasonal dynamics of tick infestation in cattle in various natural zones of West Kazakhstan region. To determine infestation of ixodids by piroplasmids using the PCR method. Seasonal dynamics, the index of tick abundance in cattle and the infestation of ixodids by piroplasmids, necessary for the development of preventive measures, will be determined.

3. To determine the age dynamics of ixodidae infestation in cattle in various natural zones of WK region and their distribution on the body of animals, taking into account the age structure (larva – nymph – imago).

4. To study epizootic situation regarding piroplasmosis in cattle in various natural zones of WK region. The extent of invasion of cattle by piroplasmids and their type will be determined by studying blood smears and PCR, necessary for the development of preventive measures.

5. To determine the nature of the course and symptoms of piroplasmosis in cattle in various zones of WK region. The nature of the course and symptoms of the disease necessary for the development of preventive measures will be determined.

6. To determine seasonal and age-related dynamics of piroplasmosis in cattle in various zones of WK region using the PCR method. Seasonal and age dynamics of piroplasmosis in cattle will be determined, which are necessary for the development of preventive measures.

7. To determine medication effectiveness against piroplasmosis. The effectiveness of anti-pyroplasmidose medication will be determined using PCR, a complex for pathogenetic therapy of cattle will be compiled, necessary for the development of preventive measures..

8. To study the effectiveness of acaricides used against ixodids. The effectiveness of acaricides will be determined by invitro and invivo methods, necessary for the development of preventive measures.

The seasonal dynamics of infection of cattle with ticks was determined by quarterly (winter, spring, summer and autumn) animal studies, and age-based studies of various age groups: under one year, 1-3 years, 4-5 years, 6 years and older. The collection of ticks from vegetation was carried out on the “flag”. The collection of ticks from cattle was carried out with tweezers in cans with a capacity of 100 mm3. In the steppe, semi-desert and desert zones of the West Kazakhstan region, cattle are infected with ticks of the Ixodidae family, belonging to five genera and ten species of ticks. The highest infection rate was observed in spring and summer and ranged from 100 to 90%. The greatest animal infestation was recorded in the steppe zone, and the lowest in the desert zone. Index of occurrence is averaged 55%, the highest index of abundance was determined in H. detritum – 59.3±12.1, and the lowest in I. ricinus – 3.5±1.0 ex/head. Young animals under the age of one year and from 1 to 3 years old were most affected, and the index of abundance was 216.2 – 252.4 ex/head, respectively.

Novelty: the development of a rational scheme for the treatment and prevention of pyroplasmidosis, and ways to control ticks.

1. Distribution and species composition of ixodid ticks in cattle in the steppe, semi-desert and desert zones of West Kazakhstan region will be determined.

2. Seasonal dynamics, tick abundance index in cattle and ixodid piroplasmid infestation will be determined using the PCR method.

3. Age dynamics of ixodid infestation in cattle, the distribution of ixodids on the body of animals, taking into account age structure (larva – nymph – imago) and the total stock of ixodids in various natural zones of West Kazakhstan region will be determined.

4. The extent of invasion of cattle by piroplasmids and their type will be determined by studying blood smears and PCR in various natural zones of West Kazakhstan region.

5. The nature of the course and symptoms of piroplasmosis in cattle in various zones of West Kazakhstan region will be determined.

6. Seasonal and age-related dynamics of piroplasmosis in cattle will be determined in various zones of West Kazakhstan region using the PCR method.

7. Comparative assessment of the effectiveness of the medication used against bovine piroplasmosis using PCR in the steppe, semi-desert and desert zones of West Kazakhstan region will be given.

8. Effectiveness of acaricides used against ixodid ticks using invitro and invivo methods will be determined.

9. Rational scheme will be developed and recommendations will be prepared for the prevention of piroplasmosis and ixodidosis in cattle in West Kazakhstan region.
