[The effects of intestinal parasites on enteric bacterial flora]

Intestinal parasites, can cause malabsorption syndromes and shifts in intestinal bacterial flora. In this study 200 cases with parasitic infestations were examined in regard to their intestinal flora. The series included 96 giardiasis. 58 Ascariasis, 20 Oxyuriasis and 17 H. nana 14 T. trichiura, 8 Tenia cases. The stool cultures yielded mainly E. coli, Strep. faecalis and other gram negative enteric bacteria, yeasts along with uncommon species as B. subtilis, Herellea, Shigella at low frequencies. The control group of 50 patients without parasitic infestations had the same distribution ratio for the same species. The observed frequencies of the isolated bacterial species showed no significant differences between the parasite positive and control cases.
