Identification of Helminths of Domestic Carnivores in Azerbaijan and the Role of Intermediate Hosts in Their Spread

In the formation of helminth fauna, the formation of a high diversity of species, in the circulation of helminths between humans and ruminant domestic animals in nature and in their infection, in the completion of the development stages of biohelminths and their invasion and in the transfer of dangerous helminths from one area to another, their intermediate hosts have a great role. When determining the role of intermediate hosts in the spread of helminths of domestic carnivores, it was found that the intermediate hosts of 12 species of helminths are insects, 7 species are ruminants, 16 species are rodents, 5 species are reptiles and 3 species are earthworms. During the study, it was found that rodents were infected with cysticercoids of the mentioned helminths in 49.3%, reptiles with cysticercoids, procercoids and plerocercoids in 34.7%, snails in 24.7% and insects in 37.3%. Among the intermediate hosts, rodents prevail over other intermediate hosts with 16 species and infection rate of 49.3%. It comes from the ethology of rodents. The scientific-research work carried out in this direction has important theoretical and practical importance. The main direction in the fight against intermediate hosts is to break the chain between transmissible diseases and the agent that transmits them.
