The authors analyze the individual variability of the agent of scabies in populations on individual patients and in foci of the disease. They define an elementary micropopulation and a focal population notions. A total of 763 females, collected from the hands of 100 patients with scabies were examined. The findings evidence that the degree of the chetoid covering joining in the mite females, assessed in grades, may be regarded as an indicator of the population status in the pathologic process. Grades II and III females predominate in the mite population on the patients during the initial period of the disease (up to a month), whereas in the course of a full-bloom process (over a month) Grades I and 0 females prevail. The attendant exo- and endogenous factors shift the grade composition of the females towards the higher grades whatever the length of the disease. A great variety of the females in focal populations evidences reinfection and continuity of the process.
作者分析了疥疮病原体在个体患者群体和疾病病灶中的个体变异性。他们定义了基本微种群和病灶种群的概念。共检查了从100名疥疮患者手上采集的763只雌性螨虫。研究结果表明，以等级评估的雌螨螯肢覆盖连接程度可被视为病理过程中种群状态的一个指标。在疾病初期（长达一个月），患者身上的螨种群中II级和III级雌螨占主导，而在疾病全盛期（超过一个月），I级和0级雌螨占优势。无论病程长短，伴随的外源性和内源性因素都会使雌螨的等级组成向更高等级转变。病灶种群中雌螨种类繁多，表明存在再感染和疾病过程的连续性。
