Subpopulation characteristics of egg-contaminating salmonella enterica serovar enteritidis as defined by the lipopolysaccharide O chain

Article Abstract:

Characterization of Almonella entercia serovar Enteritidis is refined by incorporating new data from isolates obtained from avian sources, from the spleens of naturally infected mice and from the United Kingdom into an existing lipopolysaccharide (LPS) O-chain compositional database. Results suggest that diet environment and other factors that alter cecal physiological needs to be investigated as a means to reduce egg contamination.

Use of a quartz crystal microbalance to investigate the antiadhesive potential of N-acetyl-L-cysteine

Article Abstract:

A report that N-acetyl-cysteine (NAC)-coated stainless steel and polystyrene surfaces affect both the initial adhesion of Bacillus cereus and Bacillus subtilis and the viscoelastic properties of the interaction between the adhered bacteria and the surface, are presented. The results suggest that exponentially grown cells gave rise to a positive frequency shift as long, as their cell surface hydrophobicity was zero.
