For the first time lipopolysaccharides (LPS) of 6 Budvicia aquatica strains--representatives of new Enterobacteriaceae species have been isolated. It was shown that the yield of LPS ranged from 0.9 to 7.0 % of cells dry weight. On the basis of monosaccharide composition LPS of tested strains may be referred to 3 groups. The serological studies indicated the immunochemical heterogeneity of B. aquatica species: LPS interacted only in homological system and showed no cross-reactivity with heterological antisera.

Article Synopsis
- * E. coli 126 LPS demonstrated higher toxicity compared to other E. coli strains and related bacteria, while being less pyrogenic than pyrogenal, with a bimodal distribution seen in SDS-PAGE.
- * Immunological tests revealed that E. coli 126 LPS had unique antigenic properties, and its O-specific polysaccharide structure matched that of E. coli serogroup O15, indicating distinct characteristics that differentiate it from other E. coli strains.
A lipopolysaccharide (LPS) from Budvicia aquatica DRL 20186 was isolated, studied, and chemically identified. It was shown to be lowly toxic, but highly pyrogenic. Its fatty acid composition was similar to that of the LPS from other Enterobacteriaceae, with predominance of tetradecanoic (32.

The following structure of the O-specific polysaccharide (O-antigen) of Budvicia aquatica 20186 was elucidated by sugar analysis along with 1D and 2D (1)H and (13)C NMR spectroscopy: →4)-α-L-Rhap-(1→3)-α-D-Galp-(1→2)-α-Yerp-(1→3)-β-D-GalpNAc-(1→ where Yer stands for 3,6-dideoxy-4-C-[(S)-1-hydroxyethyl]-D-xylo-hexose (yersiniose A).

A Gram-negative, rod-shaped, weakly motile, non-spore-forming bacterium (D9(T)) was isolated from the gut of Cylindroiulus fulviceps (Diplopoda) on 1/3-strength nutrient agar plates. On the basis of 16S rRNA gene sequence similarity, strain D9(T) was shown to be phylogenetically closely related to the type strain of Budvicia aquatica, the sole species of the genus Budvicia, family Enterobacteriaceae. The similarity of the 16S rRNA gene sequences of strain D9(T) and B.
