[Parasitic diseases in domestic dogs and cats in the megalopolis of Moscow].

In Moscow, 7 species of helminths and 5 species of protozoa were found in domestic dogs and 6 species of helminths and 6 species of protozoa were detected in domestic cats. Such a great variety in pararistic diseases is distinguished for a low, but steady-state extensity of invasion. The change in socioeconomic relations accompanied by a gradual rise in the number of domestic and stray dogs in the megalopolis may create prerequisites for not only the spread, but also occurrence of parasitic diseases that have not been earlier notified in the city.
