    Trichomonas hominis
    Opis:
    The flagellate Trichomonas hominis is often identified in human diarrheic stools. Because of the fecal-oral transmission rout, infection with 7. hominis is more frequently reported in children than in adults. Although infections with the trichomonads in some world regions are as often as with Giardia, no prevention and optimal treatment are defined. The purpose of our in vitro studies was to examine susceptibility of T. hominis to a newly synthesized imidazole derivative — 1-metylo-2-(2,4-dinitrobenzylotio)-1H-imidazol — P27; in order to make a comparison between this new and previously known compounds, chlorhexidine and metronidazole were used. The protozoans derived from the diarrheic stool of adult patient were grown on the liquid Pahm medium and subcultured twice a week. Assays of trichomonad cultures were incubated with one of the following substances: chlorhexidine, metronidazole or P27. For each compound, two different concentrations were applied. After 24h exposition, an antitrichomonal effect of the above substances was assessed, namely a quantity of the surviving trichomonads was microscopically determined and compared with that observed in control cultures. The protozoans showed different susceptibility, depending on kind and concentration of tested compound. In comparison to the control cultures, the reduction in number of surviving protozoans appeared in the assays with metronidazole, chlorhexidine and P27 (to 63%, 52% and 8.7%, respectively). The highest in vitro susceptibility of 7. hominis was revealed to a new imidazole derivative P27. The obtained results allow us to suppose that the further studies in this field will be very helpful for explaining the mechanisms of the antitrichomonal activity of the tested compounds as well as for assessment of the influence of various abiotic factors.

    Opis:
    In this research, a comparative analysis of results of investigations involving different human populations, in terms of a relation between the oral cavity health and the species composition of mouth microbiota is reported. The purpose of this analysis was to identify and assess microorganisms that could cause health complications in patients with neoplasm requiring dental problem-related surgical management. The patients with the oral cancer surgically treated and those without neoplasm were assessed for their oral health: status of teeth, gingiva, periodontium, and occurrence of inflammatory processes. From each patient, microorganisms isolated of periodontium, dental plaque, and dental pocket swabs were identified in wet and stained microscopic preparations; standard microbiology in vitro techniques were also applied to determine the fungal and bacterial strains. The comparative analysis of results of direct microscopic examinations and in vitro cultures assessment indicated significant differences in prevalences of fungi, parasitic oral protozoans and bacteriae in particular patient’s groups. Yeast-like fungi belonging to Candida genus, mostly of C. albicans group, were identified in 93.75% patients with the oral cancer, while in 25% of individuals assessed without neoplasm. E. gingivalis amoebae were only found in 12.5% patients with the serious disease; no trichomonads were detected in all patients analyzed. Among bacteria species, potentially pathogenic Enterobacteriaceae were found in the patients with oral cancer. The pronounced shift in the microbiota species composition in the patients who needed prolonged treatment due to oral cavity cancer, compared to other generally healthy persons has been showed in this analysis.

    Opis:
    The retrospective analysis of data on oral cavity clinical status in relation to microbiota species composition is presented. The research regards patients of different age, with and without congenital malformation, pretreatment assessed for occurrence of pathological changes in the masticatory system. Samples of the swabs collected from each patient (from dental plaque, periodontium and dental pockets) were used for identification of oral protozoans in wet slides and stained preparations; additionally, transmission electron microscope examination was performed. The material was used for in vitro cultures to identify bacteria strains. Clinically, intensity of tissue deteriorations was higher in patients with a congenital disease. Alive Trichomonas tenax and Entamoeba gingivalis, species with confirmed pathogenic impact on oral cavity and neighboring structures, were detected with higher prevalence in older patients. Enterococci, Staphylococcus aureus, various Enterobacteriaceae were more frequently detected in patients with somatic and mental retardations; in mouths of those patients, Klebsiella pneumonia and Pseudomonas aeruginosa opportunistic strains occurred. Masticatory system abnormalities favor colonization of oral cavity by exogenous species and dissemination of infections, especially dangerous for patients with congenital diseases. Oral microbiota assessment and preventive measures may be helpful to avoid subsequent peri-surgery complications.
