BIODIVERSITY OF THE PARASITE FAUNA IN THE NORTHERN REGIONS OF ARMENIA AND THE LAKE SEVAN BASIN

Abstract

The variety of parasite species, infection of domesticated animals (including cattle,
 sheep, goats, rabbits, poultry, dogs and pigs), natural infection of biohelminths'
 intermediate hosts (including terrestrial and freshwater mollusks, soil oribatid mites)
 with helminth larvae, and the species composition of tick vectors of blood protozoan
 diseases have been studied. The studies found the infection of the above animals with
 the following helminth species: 4 trematode species Fasciola hepatica, F. gigantica,
 Dicrocoelium lanceatum, Paramphistomum sp., 13 nematode species Ascaris suum, A.
 galli, Syngamus trachea, Capillaria caudinflata, Trichuris ovis, Tr. suis, Metastrongylus
 elongatus, Chabertia sp., Haemonchus sp., Protostrongylus spp., Muellerius capillaris,
 Dictyocaulus filaria, Cystocaulus nigrescens, 2 cestode species Moniezia expansa, M.
 benedeni; 9 eimeria species Eimeria arloingi, E. intricata, E. stidae, E. magna, E.
 perforans, E. tenella, E. acervulina, and E. exigua; 3 Haemosporidia species Babesia
 bigeminum, B. ovis, and B. canis; and 1 Leishmania species Leishmania tropica.
 There were also detected 17 species of ticks, vectors of blood protozoan diseases of
 animals, and intermediate hosts of moniezia were isolated. Two species of terrestrial
 and 3 species of freshwater mollusks being as intermediate hosts of helminths were
 recorded.
