[occurrence of the protozoa, entamoeba gingivalis and trichomonas tenax in the mouths of children and adolescents with hyperplastic gingivitis caused by phenytoin].	the oral protozoa entamoeba gingivalis and trichomonas tenax do not occur in small children and are rarely found in older ones. in adolescents their occurrence rate keeps increasing with age. they parasitize in an oral cavity changed by inflammation, yet also in a healthy mouth. their highest occurrence rate has been recorded in adults with periodontosis and atrophy of the periodontium, a somewhat lower one in adults with gingivitis. the authors addressed the question whether the presumed low oc ...	1992	1525687
cloning and characterization of a repetitive dna sequence specific for trichomonas vaginalis.	a family of 650-bp-long repeats from the trichomonas vaginalis genome, designated the tv-e650 family, was cloned and sequenced. the nucleotide sequence is a+t-rich (73.3% a+t in the consensus sequence) and highly conserved among the 8 molecular clones analyzed. the differences among the clones are single-nucleotide and 2-nucleotide substitutions and insertions or deletions. the sequence uniformity of the clones as well as the presence of identical mutations in different clones suggest that effic ...	1992	1435862

[a study of the frequency of protozoa and yeasts isolated from the parodontium of 509 subjects (author's transl)].	the protozoa entamoeba gingivalis and trichomonas tenax together with yeasts of the genus candida were investigated in the mouth (gums or neck of tooth) of 509 healthy or diabetic subjects. a study of the possible correlation between presence of these parasites and various local or general factors, showed that neither the sex, maxillo-facial anomalies nor smoking had any influence on parasite incidence. entamoeba gingivalis was encountered in 85 per cent of subjects free from parodontopathy. num ...	1979	395489
[oral protozoans and diabetes: study in 117 patients].	a study on the presence of oral entamoeba gingivalis and trichomonas tenax has been carried out on calculus or dental plaque from 117 diabetic subjects. statistical analysis of results shows no correlation between diabetes and protozoa. the same frequency was found between diabetic and normal subjects. nevertheless, a significant relation has been found between the diabetes and the yeasts.	1979	372177
[study of an oral protozoan trichomonas tenax using scanning and transmission electron microscopy].	the study with scanning and transmission electron microscopy of trichomonas tenax gave morphological information on this protozoon. the oval-shaped cell body showed at the anterior pole four free flagella and a trailing flagellum which had an undulating membrane. the axostyle which consisted of microtubules and produced the cellular rigidity emerged at the posterior pole. an ovoid nucleus and a well-developed golgi apparatus were located at the anterior pole. at the latter, a pelta consisting of ...	1979	287668
cultivation of trichomonas gallinarum and trichomonas tenax on a trimed medium.	studied was the possibility to isolate and culture tr. gallinarum and tr. tenax on a medium trimed, proposed by the authors for the isolation and cultivation of tr. vaginalis. the growth and development of the two trichomonas species were followed up at various temperatures -- 38 degrees, 36 degrees, and 32 degrees c, in order to establish the most appropriate temperature for continuous cultivation at longer intervals of reseeding as well as the temperature optimum for the fast deposition of gre ...	1975	843
