| yersiniophage phir1-37 is a tailed bacteriophage having a 270 kb dna genome with thymidine replaced by deoxyuridine. | bacteriophage pir1-37 was isolated based on its ability to infect strain yeo3-r1, a virulence-plasmid-cured o antigen-negative derivative of yersinia enterocolitica serotype o : 3. in this study, the phage receptor was found to be a structure in the outer core hexasaccharide of y. enterocolitica o : 3 lps. the phage receptor was present in the outer core of strains of many other y. enterocolitica serotypes, but also in some yersinia intermedia strains. surprisingly, the receptor structure reside ... | 2005 | 16339954 |
| characterization of the six glycosyltransferases involved in the biosynthesis of yersinia enterocolitica serotype o:3 lipopolysaccharide outer core. | yersinia enterocolitica (ye) is a gram-negative bacterium; ye serotype o:3 expresses lipopolysaccharide (lps) with a hexasaccharide branch known as the outer core (oc). the oc is important for the resistance of the bacterium to cationic antimicrobial peptides and also functions as a receptor for bacteriophage phir1-37 and enterocoliticin. the biosynthesis of the oc hexasaccharide is directed by the oc gene cluster that contains nine genes (wzx, wbcklmnopq, and gne). in this study, we inactivated ... | 2010 | 20595390 |
| Identification of distinct lipopolysaccharide patterns among Yersinia enterocolitica and Y. enterocolitica-like bacteria. | The lipopolysaccharide (LPS) of strains representing various serotypes of Yersinia enterocolitica and Y. enterocolitica-like bacteria was studied by deoxycholate-PAGE and silver staining analysis. Four main types of LPS were detected based on the O-polysaccharide (O-PS): (i) LPS with homopolymeric O-PS, (ii) LPS with ladder-forming heteropolymeric O-PS, (iii) LPS with single-length O-PS, and (iv) semi-rough LPS without O-PS. Within the first three types, several subvariants were detected. Select ... | 2011 | 21999544 |
