Formation of Biodiversity of Parasite Fauna in Conditions of Foothills Ecosystem of Razdan-Marmarik Region of Armenia
The fauna of parasites of domestic animals (cows, sheep, rabbits, hens), ixodes ticks, as well as paths of circulation of some biohelminths in conditions of foothills ecosystem of Razdan-Marmarik region of Armenia have been studied. It's been found that fauna of animal parasites in the region consists of 33 species, including 17 species of helminths: 2 trematodes (Dicrocoelim lanceatum, Fasciola hepatica); 4 cestodes (Moniezia expansa, M. benedeni, Echinococcusgranulosus larvae, Cysticercus taenicollis); 11 nematodes (Chabertia ovina, Haemonchus contortus, Nematodirus spathiger, Trichocephalus ovis, Dictyocaulusfilaria, Cystocaulus nigrescens, Muellerius capillaries, Protostrongylus sp., Ascaridia galli, Heterakis gallinarum, Passalurus ambigus); 3 species of blood parasites (Piroplasma bigeminum, P. ovis and Theileria ovis); 8 species of Protistae (Eimeria tenella, E. maxima, E. acervulina, E. irresidua, E. media, E. magna, E. perforans and E. exigua) and 4 species of ticks (Hyalomma sp., Rhipicephalus bursa, Boophilus calcaratus, Dermacentor marginatum). Fauna of land mollusks is able to be intermediate hosts of Dicrocoelim and Protostrongylus helminths includes the single species Napaeopsis hohenackeri while freshwater mollusks include Lymmnaea truncatula and Planorbis planorbis, with L. truncatula able to be an intermediate host of trematode Fasciola hepatica.
