S-Layered Aneurinibacillus and Bacillus spp. Are Susceptible to the Lytic Action of Pseudomonas aeruginosa Membrane Vesicles

Kadurugamuwa, J. L., Mayer, A., Messner, P., Sára, M., Sleytr, U. B., Beveridge, T. J.

When S-layered strains of Bacillus stearothermophilus and Aneurinibacillus thermoaerophilus, possessing S-layers of different lattice type and lattice constant as well as S-(glyco)protein chemistry,...

Influence of cephalosporins and iron on surface protein antigens of Klebsiella pneumoniae in vivo.

Kadurugamuwa, J L, Anwar, H, Brown, M R, Hengstler, B, Kunz, S, Zak, O

The outer membrane protein (OMP) profiles of Klebsiella pneumoniae grown in a rabbit peritonitis model in the presence or absence of cephalosporins were investigated. Six high-molecular-weight OMPs...

Effect of subinhibitory concentrations of cephalosporins on surface properties and siderophore production in iron-depleted Klebsiella pneumoniae.

Kadurugamuwa, J L, Anwar, H, Brown, M R, Zak, O

Subinhibitory MICs (sub-MICs) of several cephalosporins significantly reduced the enterochelin production of Klebsiella pneumoniae 327 grown under iron-depleted conditions and also reduced capsule...

Virulence factors are released from Pseudomonas aeruginosa in association with membrane vesicles during normal growth and exposure to gentamicin: a novel mechanism of enzyme secretion.

Kadurugamuwa, J L, Beveridge, T J

Pseudomonas aeruginosa blebs-off membrane vesicles (MVs) into culture medium during normal growth. Release of these vesicles increased approximately threefold after exposure of the organism to four...

Bacteriolytic effect of membrane vesicles from Pseudomonas aeruginosa on other bacteria including pathogens: conceptually new antibiotics.

Kadurugamuwa, J L, Beveridge, T J

Pseudomonas aeruginosa releases membrane vesicles (MVs) filled with periplasmic components during normal growth, and the quantity of these vesicles can be increased by brief exposure to gentamicin....

Protein antigens of encapsulated Klebsiella pneumoniae surface exposed after growth in the presence of subinhibitory concentrations of cephalosporins.

Kadurugamuwa, J L, Anwar, H, Brown, M R, Zak, O

It recently has been reported by us that cephalosporins, at a concentration below that influencing growth rate, reduced the production of enterochelin and capsule formation of iron-depleted...

Interaction of gentamicin with the A band and B band lipopolysaccharides of Pseudomonas aeruginosa and its possible lethal effect.

Kadurugamuwa, J L, Lam, J S, Beveridge, T J

The lipopolysaccharide (LPS) of Pseudomonas aeruginosa PAO1 possesses two distinct types of O polysaccharide, A and B band LPSs, but the majority of clinical isolates from cystic fibrosis patients...

Surface action of gentamicin on Pseudomonas aeruginosa.

Kadurugamuwa, J L, Clarke, A J, Beveridge, T J

The mode of action of gentamicin has traditionally been considered to be at the 30S ribosomal level. However, the inhibition of bacterial protein synthesis alone appears to be insufficient to...

Intercellular spread of Shigella flexneri through a monolayer mediated by membranous protrusions and associated with reorganization of the cytoskeletal protein vinculin.

Kadurugamuwa, J L, Rohde, M, Wehland, J, Timmis, K N

The spread of Shigella flexneri in a monolayer of infected Henle and HeLa cells was studied by using immunofluorescence and electron microscopy. Infected cells produced numerous bacterium-containing...

Media for study of growth kinetics and envelope properties of iron-deprived bacteria.

Kadurugamuwa, J L, Anwar, H, Brown, M R, Shand, G H, Ward, K H

Ion-exchange chromatography was used to remove iron from complex and chemically defined laboratory media. The kinetics of metal cation removal from the media was investigated by using atomic...
