Journal ArticleDOI
Chitosan disrupts the barrier properties of the outer membrane of gram-negative bacteria.
TL;DR: Electron microscopy showed that chitosan caused extensive cell surface alterations and covered the OM with vesicular structures, explaining the loss of the barrier function of the outer membrane, which makes chitOSan a potentially useful indirect antimicrobial for food protection.
Journal ArticleDOI
Antimicrobial Actions of Degraded and Native Chitosan against Spoilage Organisms in Laboratory Media and Foods
Jonathan Rhoades,Sibel Roller +1 more
TL;DR: It is concluded that native chitosan has potential for use as a preservative in certain types of food but that the increase in antimicrobial activity that occurs following partial hydrolysis is too small to justify the extra processing involved.
Journal ArticleDOI
Prevalence and concentration of verocytotoxigenic Escherichia coli, Salmonella enterica and Listeria monocytogenes in the beef production chain: a review.
TL;DR: Seasonal variation was evident in many surveys, faecal prevalences of E. coli O157 and Salmonella generally being higher in the warmer months, and the significance of non-O157 serotypes of VTEC and their detection and classification are discussed.
Journal ArticleDOI
Microbiological quality of retail cheeses made from raw, thermized or pasteurized milk in the UK
Christine L. Little,Jonathan Rhoades,S. K. Sagoo,John P. Harris,M. Greenwood,V Mithani,Kathie Grant,Jim McLauchlin +7 more
TL;DR: Cheeses were of unsatisfactory quality more frequently when sampled from premises rated as having little or no confidence in management and control systems, and stored/displayed at above 8 degrees C.
Journal ArticleDOI
Inhibition of the adhesion of enteropathogenic Escherichia coli strains to HT-29 cells in culture by chito-oligosaccharides
TL;DR: The ability of chito-oligosaccharides (COS) to inhibit selected intestinal bacteria was investigated and dose–response curves were constructed to further characterise the inhibition of EPEC strains to HT29 cells.
