Four distinctive plasmid profile types have been identified in strains of Salmonella gold-coast isolated in Britain. Strains of one type, designated plasmid profile type 4, caused an extensive outbreak of food-poisoning in 1984, and it has been confirmed that the vehicle of infection was imported French pâté.
We compared the gating, ion conduction, and pharmacology of large-conductance Ca(2+)-activated K+ channels (BK channels) from canine colon in artificial lipid bilayers and in excised patches. Both protocols identified 270-pS K(+)-selective channels activated by depolarization and Ca2+ (approximately 130-mV shift of half-activation voltage per 10-fold change(More)
AIMS To report the incidence of nontyphoidal salmonellas in England and Wales and identified in the Division of Enteric Pathogens, London between 1981 and 1990. METHODS Strains were serotyped and phage typed for Salmonella typhimurium, S enteritidis, and S virchow, using established methods. RESULTS Overall, less than 2% of nontyphoidal salmonellas(More)
In March 1988, there was an outbreak of infection by a strain of Salmonella saint-paul with a distinctive antigenic marker. A total of 143 reports were received between 1 March and 7 June. Preliminary investigations suggested that raw beansprouts were a possible source of infection and a case-control study confirmed the association. S. saint-paul of the(More)
A national outbreak of salmonellosis caused by a rare serotype occurred between July and November 1989. A total of 40 cases of Salmonella manchester infection were identified by the PHLS Division of Enteric Pathogens with a further 7 cases reported from Scotland. The median age of those affected was one year. All strains from the outbreak carried a 70mDal(More)
Our preliminary indentation experiments showed that the equilibrium elastic modulus of murine tibial cartilage increased with decreasing indenter size: flat-ended 60 deg conical tips with end diameters of 15 microm and 90 microm gave 1.50+/-0.82 MPa (mean+/-standard deviation) and 0.55+/-0.11 MPa, respectively (p<0.01). The goal of this paper is to(More)
Current management of chronic heart failure involves reducing the personal and economic burden through controlling symptoms, reducing hospital admissions, and slowing the progression of ventricular dysfunction. As healthcare providers struggle to control the rising costs of health and illness care while reducing morbidity and mortality rates associated with(More)
