ABSTRACT The occurrence of 131I-compounds in human faeces was studied after intravenous administration of 131I-thyroxine. The excretion of the radioactivity during 12 days ranged from 7.8 to 32.1 per cent of the dose administered with a mean of 16.0 (± 1.76). The radioactivity in the faeces was derived from free 131I-thyroxine. The total amount of faeces did not seem to influence the total excretion of the dose administered. After administration of 131I-triiodothyronine to rats and humans, triiodothyronine occurred in the bile mainly conjugated with glucuronic acid, but a considerable part of the radioactivity was found in diiodotyrosine. The radioacivity of human faeces after the administration of 131I-triiodothyronine was derived from free triiodothyronine. After injection of 131I-diiodotyrosine only labelled iodide was detected in the bile of rats. In the bile of humans most of the radioactivity was derived from iodide, and a small part of it was found in diiodotyrosine.

© 2017 IUMS. A novel anaerobic pectinolytic bacterium (strain 14T) was isolated from human faeces. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 14T belonged to the family Ruminococcaceae, but was located separately from known clostridial clusters within the taxon. The closest cultured relative of strain 14T was Acetivibrio cellulolyticus (89.7% sequence similarity). Strain 14T shared ~99% sequence similarity with cloned 16S rRNA gene sequences from uncultured bacteria derived from the human gut. Cells were Gram-stain-positive, non-motile cocci approximately 0.6μm in diameter. Strain 14T fermented pectins from citrus peel, apple, and kiwifruit as well as carbohydrates that are constituents of pectins and hemicellulose, such as galacturonic acid, xylose, and arabinose. TEM images of strain 14T, cultured in association with plant tissues, suggested extracellular fibrolytic activity associated with the bacterial cells, forming zones of degradation in the pectin-rich regions of middle lamella. Phylogenetic and phenotypic analysis supported the differentiation of strain 14T as a novel genus in the family Ruminococcaceae. The name Monoglobus pectinilyticus gen. nov., sp. nov. is proposed; the type strain is 14T (JCM 31914T=DSM 104782T).

Gene Sequence Analysis

A bacterial strain isolated from human faeces, M-165T, was characterized in terms of its phenotypic and biochemical features, cellular fatty acid profile, menaquinone profile and phylogenetic position (based on 16S rRNA gene sequence analysis). A 16S rRNA gene sequence analysis showed that the isolate was a member of the genus Parabacteroides. Strain M-165T was closely related to Parabacteroides merdae strains, showing 98 % sequence similarity. The strain was obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative, rod-shaped and was able to grow on media containing 20 % bile. Although the phenotypic characteristics of the strain M-165T were similar to those of P. merdae, the isolate could be differentiated from P. merdae by means of API 20A tests for l-arabinose and l-rhamnose fermentation. DNA–DNA hybridization experiments revealed the genomic distinctiveness of the novel strain with respect to P. merdae JCM 9497T (⩽60 % DNA–DNA relatedness). The DNA G+C content of the strain is 47.6 mol%. On the basis of these data, strain M-165T represents a novel species of the genus Parabacteroides, for which the name Parabacteroides johnsonii sp. nov. is proposed. The type strain is M-165T (=JCM 13406T=DSM 18315T).

An analysis of viscosity data from sets of raw data on the shear rheological properties of fresh human faeces was performed to generate model constants that can be used for the design of faecal treatment processes. The models selected are standard choices in computational fluid dynamics software for shear-thinning fluids. Initial screening for model selection was based on a literature review of similarly viscous materials. Results showed reasonable agreement with Power Law (PL). PL model parameters were proposed for fresh human faeces and correlated against sample properties. A PL model for shear stress as a function of moisture content was proposed.
