Loss of Very-Long O-Antigen Chains Optimizes Capsule-Mediated Immune Evasion by Salmonella enterica Serovar Typhi

mBio, 2013
Expression of capsular polysaccharides is a variable trait often associated with more-virulent forms of a bacterial species. For example, typhoid fever is caused by the capsulated Salmonella enterica serovar Typhi, while nontyphoidal Salmonella serovars ...

Population-based analysis of invasive nontypeable pneumococci reveals that most have defective capsule synthesis genes. [PDF]

PLoS ONE, 2014
Since nasopharyngeal carriage of pneumococcus precedes invasive pneumococcal disease, characteristics of carriage isolates could be incorrectly assumed to reflect those of invasive isolates.

Novel Acinetobacter baumannii Myovirus TaPaz Encoding Two Tailspike Depolymerases: Characterization and Host-Recognition Strategy

Viruses, 2021
Acinetobacter baumannii, one of the most significant nosocomial pathogens, is capable of producing structurally diverse capsular polysaccharides (CPSs) which are the primary receptors for A.

Determination of the binding affinities of Neisseria meningitidis serogroup W capsule polymerase with two nucleotide sugar substrates

BMC Research Notes, 2018
Objective Meningococcal meningitis is a public health burden. Immunization strategies have reduced global incidence of the disease. Glycoconjugate vaccines are the most effective type of vaccine to combat most causes of meningococcal meningitis.

IMMUNOCHEMISTRY OF THE CAPSULAR POLYSACCHARIDE OF AN Acinetobacter [PDF]

Proceedings of the National Academy of Sciences, 1969
The capsular polysaccharide of a strain, BD4, of Acinetobacter calco-aceticus (A.c-a), composed of L-rhamnose and D-glucose, 4:1, precipitates all streptococcal group B antisera tested, as well as streptococcal group G antisera and antipneumococcal (Pn) type XXIII serum.

ATP-Binding Cassette (ABC) Transporters and Antibiotic Resistance: Specialized Systems for Capsular Polysaccharide Export in Gram-Negative Pathogens

Polysaccharides
ABC transporters are a large family of proteins that mediate the export or import of a variety of molecules, including capsular polysaccharides. The capsules are an important virulence factor that protect bacteria from host immune system attacks ...

Two variants among Haemophilus influenzae serotype b strains with distinct bcs4, hcsA and hcsB genes display differences in expression of the polysaccharide capsule

BMC Microbiology, 2008
Background Despite nearly complete vaccine coverage, a small number of fully vaccinated children in the Netherlands have experienced invasive disease caused by Haemophilus influenzae serotype b (Hib).

Capsular Polysaccharide of Group AStreptococcus [PDF]

Microbiology Spectrum, 2014
ABSTRACTMost clinical isolates ofStreptococcus pyogeneselaborate a capsular polysaccharide, which is composed of hyaluronic acid, a high-molecular-mass polymer of alternating residues ofN-acetyl glucosamine and glucuronic acid. Certain strains, particularly those of the M18 serotype, produce abundant amounts of capsule, resulting in formation of large,

Screening of bacterial molecules with antagonistic or adjuvant activity [PDF]

, 2010
The Lipopolysaccharides (LPSs) are the major constituents of the outer membrane of Gram-negative bacteria and the interest in their chemical characterization is motivated by the close correlation existing between the structure and the biological activity
