РOTENTIAL RISK FACTORS FOR BLASTOCYSTIS HOMINIS INVASION

Abstract

The findings of a study conducted to assess household and biological risk factors for Blastocystis spp. infection through clinical and epidemiological methods are presented. In order to achieve the goal, 1720 examinations were conducted in 2016-2018 in the Department of Epidemiology of AMU to determine the level of prevalence of blastocyst infection. The incidence of blastocyst invasion and the prevalence level in 2018 was higher compared to other years. Among all risk factors for blastocyst invasion, skin diseases can be mentioned as a significant factor (OR = 5.68, CI 95% 1.12-29.01) p<0.05. A high risk of infection was also identified for the presence of viral hepatitis and the use of untreated tap water. In patients suffering from skin diseases and with B. Hominis infestation, against the background of dysbiotic changes, an increase in the quantitative indicators of conditionally pathogenic microorganisms - Klebsiella, Staphylococcus, Candida, and a decrease in the number of obligate microflora, especially Lactobacillus, Bifidobacterium, was observe.
