[Intestinal protozoa in children of child day care centers and orphanages of Moscow].

On the basis of an analysis of the contamination with intestinal protozoa in 373 Moscow children and comparison of the data of a randomized protozoological study of matched groups of 543 children from three towns of the Russian Federation in the past 15 years, the authors revealed profound changes in the pattern of intestinal parasitocenosis in the examinees: preponderance of B. hominis recently reclassified as a protozoan in all groups of examinees; a reduction in the detectable protozoan types up to a single type both among parasitic amoebas (E. coli) and flagellates (L. intestinalis). The incidence of giardiasis among the children's collective bodies averaged 3.5% and that in the kindergartens was 0.5%.
