Biological diversity of Protostrongylidae lung nematodes in small ruminants (sheep, goat, mouflon, bezoar goat) of Armenia has been established. It consists of 6 species: Muellerius capillaris, Cystocaulus nigrescens, Protostrongylus kochi, P. hobmaieri, P. muraschkinzewi, P. davtiani. Mean degree of infection (mainly concomitant) in various age groups is 20,0-44,0%.

There are 44 mollusk species which can be infected Protostrongylidae by larvae recorded in Armenia. Natural infection of mollusks at pastures with Protostrongylidae is most common for the following 9 species: Helicella derbentina, Napaeopsis hohenackeri, Helix lucorum, Chondrula tridens, Hesseola solidior, Succinea putris, Pupilla muscorum, Vitrinoides monticola armeniaca and Deroceras caucasicum. Infection rates vary 0,4 to 12,8% with parasite load 1 to 63 larvae per mollusk. The most effective anthelmintics against Protostrongylidae appear to be albendazole 300, albendazole 600, alben and atozole forte 300.
