RESUMO
The southern region is marked by a high incidence of parasitic diseases and a significant contamination of environmental objects with the eggs and cysts of their pathogens. Background examinations revealed the greatest soil contamination with helminthic eggs in the Temryuksky District of the Krasnodar Territory and in the towns of Vladikavkaz and Digora of the Republic of North Ossetia (Alania). The least contamination was found in Rostov-on-Don and the towns of the south-western area of the Krasnodar Territory. The eggs of Toxocara and astamination. There is an increase in the proportion of soil positive tests from 26.6 to 50.0, with the high (up to 82.0-100.0%) viability of eggs and a rise in the intensive index of their content per kg of soil (from 2.7 to 4.7-11.0). Toxocara eggs were mainly detected. The established high proportion of seropositive persons (10.7-18.0%) among the local population is an additional verification of the wide circulation of Toxocara eggs in nature. By the helminthic egg contamination index, the soils of localities of the south of Russia are qualified as those of moderate epidemic hazard. The floods accompanied by the increased helminthological contamination of the upper soil layer may lead to a higher human risk for contamination with helminthic diseases.

A hundred and fourteen cases of subcutaneous dirofilariasis caused by Dirofilaria repens were described in the CIS in 1915-1996. The mean age of the patients was 38.4 years (from 3 to 70 years). Dirofilaria was found in the eye in 45.9% of cases, in the head and neck in 17.5%, in the arms and hands in 11.7%, in the legs in 8.1%, in the viscera in 2 cases, and in the genitalia in 2 cases, they being prevalent in the body's right part. The north boundary of local infection cases was in latitude 53-54 degrees North. The maximum cases were detected in January and June. Dirofilariasis clinically appeared as a migrating subcutaneous tumor occasionally complicated by secondary abscess. The tumor generally contained an immature female, an immature male was found in one case. The sole treatment was surgical helminthic excision. There was a trend of subcutaneous dirofilariasis cases to increase in the RF in the past decades.
