Bdellovibrio bacteriovorus

The filaments of Bdellovibrio bacteriovorus and Vibrio metchnikovii are sheathed. The core is of similar construction to that of unsheathed fila-... 

Although the cell wall of Spirillum serpens lost much of its rigidity after infection with Bdellovibrio bacteriovorus, the peptidoglycan remained as a discrete cell-wall layer. Comparisons of the abilities of some oligosaccharyl-peptides (obtained from the peptidoglycans of Staph, aureus and Lactobacillus plantarurri) to induce arthritis in rats showed that, at least, one disaccharide unit linked to a peptide is necessary. The presence of teichoic acid did not have any effect.
