ABSTRACT
Isozyme polymorphism was used for identification of apricot cultivars. 34 cultivars of 38 studied ones had unique genotype profiles for allelic composition of the AAT-1, EST-1, EST-2, SOD-1, LAP-1, PX-2 loci and AMY phenotypes. All regionized and being under State sort testing cultivars of hybridous origin were differentiated. Cultivars of clonal selection were identified regarding cultivars type.

Paper presents the RIHA and EIA data of an annual 3-year survey of populations of two reindeer breeders' settlements in the Nenets Autonomous Okrug of Arkhangelsk Province with the use of intact Echinococcus antigen (RIHA) and fractions of Echinococcus multilocularis antigens (EIA). In 1984-1986, seropositivity has been established by 2 immunoassays for 98 (21.6 +/- 1.9%) out of 454 apparently healthy subjects. The annual Echinococcus invasion rate in population varied within 2.8-3.7%, as estimated by RIHA, and 4.6-4.8%, according to EIA data. The highest invasion rate was observed among the those engaged in reindeer breeding, hunting, animal breeding as well as among the aboriginal populations the Nentsi and the Komi.

The paper presents results of an immunological screening of the population from the Nenets Autonomous Okrug of the Arkhangelsk region for echinococcosis. A high level (8.4 +/- 1.0%) of seropositivity of the population has been found to Echinococcus antigens. Occupational groups, such as reindeer-breeders, domestic servants in the tent of skins, hunters, fur-farmers, furriers) have been identified to be mostly at high risk for Echinococcus infection. Some animal species have been demonstrated to be implicated in the epidemiology of echinococcosis. The most likely source of human granulosus Echinococcus invasion is a dog whose mature Echinococcus infection rate is 5.8 +/- 3.2%, that of multilocularis Echinococcus is a polar fox whose infection rate is 40.3 +/- 4.3%.
