ABSTRACT
The aim of this work was to study clinical changes and microorganisms in mouths of three patient groups: with congenital disorders (Cd), dialyzed (D) and control (C). Fifty five patients, 20 to 62 years old were assessed. Swabs and samples of periodontal tissue were used for microscopical study to detect of protozoans and for bacterial and fungal cultures. E. gingivalis and T. tenax were found in all groups. Three out of Cd patients were infected with Acanthamoeba sp.. Fecal bacteria were more often found in D than Cd. In all 30-40 years old D patients, fecal bacteria and various strains of C. albicans occurred. We found that systemic diseases favour instabilities in mouths changing interrelations between protozoa, bacteria and fungi. It may increase risk of clinical complications.

Crowded infrapopulations of H. diminuta obtained from the WMS il1 inbred line resembled those of the potentially non-inbred WMS strain in not showing either the abrupt reductions in the numbers of worms or the destrobilation described by other autors. Denser populations of both types of tapeworm have a greather abundance of 4 - testis proglottids of the 1p3a type (having 1 testis on the poral side and three on the aporal), and fewer of type 0p3a. Changes in the positioning of genital ducts and pores show a marked positive correlation with the abundance of type 2pla proglottids. Strobilae of H. diminuta WMS il1 contain a relatively greather number of type 0p3a proglottids and fewer of type 1p3a, than those of the WMS "strain"; something which is probably linked with the respective selection of the maternal tapeworms.
