Monitoring of helminth fauna in the gastrointestinal tract of domestic reindeer in the Taimyr Dolgan-Nenets municipal district

To study the epizootic situation on the helminth infections of the domestic reindeer gastrointestinal tract we conducted our own examination. As a result, the complete helminthological autopsy revealed 4045 samples of helminthes, and among them there were: Ostertagia gruhneri (the dominant specie) - 85, O. arctica - 14%, O. circumcincta - 1% (100% the extensity of invasion [EI]); for Nematodirus skrjabini and N. longissimespiculata the EI was 86%; for Moniezia rangiferina and M.taymirica EI was 24%. Scatological studies showed age-related dynamics of infestation. In animals with ostertagiosis the EI was: for calves under 1 year - 90%; for 1-3 year’s individuals and from 3 years and older -100%. In case of monieziasis 80% animals under 1 year were infected; at the age of 1-3 years -17,2%; at the age of 3 years and older - 22,72%. In case of nematodirosis the infestation of animals under 1 year was 90%, 1-3 years - 41,%, from the age of 3 years and older - 6,8%. The highest level of infestation Ostertagia and Nematodirella, Nematodirus registered in August-September and amounted to 98.8% and 28.9%. The lowest level of contamination observed in June and July, EI Ostertagia, Nematodirella, Nematodirus and Moniezia respectively 12,2%, 2%, 1,4%. With the view of small study of this issue, further research is needed in this area to increase the productivity of the industry, the development of preventive measures and effective responses to invasive disease.
