Published: September 2007

Three 7-wk-old Bobwhite quail were submitted for necropsy to the Douglas branch of the Georgia Poultry Laboratory Network. Grossly, one bird had multiple white foci in the liver and a mild airsacculitis. In this quail there were multiple hepatic granulomas that contained mats of filamentous bacteria easily seen in hematoxylin- and eosin-stained histologic sections. These bacteria were negative with period acid-Schiff and were not acid fast. Bacteria were gram-positive but were most evident on Warthin-Starry silver-stained sections. The appearance and histochemical characteristics of these bacteria are most consistent with Eubacterium tortuosum.

A Gram-positive, non-motile, rod-shaped facultative anaerobic bacterial strain SG502 was isolated from healthy human fecal samples in Brookings, SD, USA. The comparison of the 16S rRNA gene placed the strain within the family . Within this family, ATCC 14501, strain PG-426-CC-2, DSM 3991 and DSM 3987(=ATCC 25548) were its closest taxa with 95.

Effects of fermented feeds and ginseng polysaccharides on the intestinal morphology and microbiota composition of Xuefeng black-bone chicken.

Fermented feeds contain abundant organic acids, amino acids, and small peptides, which improve the nutritional status as well as the morphology and microbiota composition of the intestine. Ginseng polysaccharides exhibit several biological activities and contribute to improving intestinal development. Here, Xuefeng black-bone chickens were fed a basal diet fermented by Bacillus subtilis, Saccharomyces cerevisiae, Lactobacillus plantarum, and Enterococcus faecium, with or without ginseng polysaccharides.

Article Synopsis
  • Four new strains of anaerobic, Gram-positive bacteria were isolated from healthy Japanese humans' fecal samples.
  • Genetic analysis revealed that these strains form a close group with a high sequence similarity to existing strains, indicating they belong to the same species.
  • Based on genome relatedness, one strain (9CBEGH2) is proposed as a new species under a novel genus name, due to significant DNA differences from related taxa.

Gram-positive, straight or slightly curved rod-shaped bacteria, designated as strains N6H1-5 and N6H1-3, were isolated from fecal samples of old dog. The analysis of 16S rRNA gene sequences indicated that the isolates belonged to the Clostridium cluster XVI and were closely related to Eubacterium dolichum KCTC 5832, Eubacterium tortuosum DSM 3987, Clostridium innocuum KCTC 5183, Allobaculum stecoricanis DSM 13633, Eubacterium limosum KCTC 3266, and Clostridium butyricum KCTC 1871, with 94.0%, 93.
