Serious infections were defined as any event in the Medical Dictionary for Regulatory Activities System-Organ Class "Infections and Infestations" that met the standard criteria for a SAE, including any infection reported as "serious" by the investigator and any infection that required hospitalization.
A fuzzy logic program was created using 155 randomly selected patients' data with four input (demographic variables) and four output classes (infections with "staphylococci", "streptococci", "Escherichia coli" or "non-E. coli gram negative rods (non-E.coli GNR)").
All infections from the System Organ Class (SOC) "Infections and Infestations" and infections reported in other SOCs identified through a manual search were defined as cases.
In order to elucidate the role of each RNR class during infection, S. Typhimurium single and double RNR mutants (as well as Fur and NrdR mutants) were used in infection assays with macrophage and epithelial cell lines.
This population is reduced through vaccination (moving to class V ), infection (moving to class I) and by natural death or emigration.
The Fraser estimator was extended by Nishiura [ 63] to allow the estimation of the reproduction number for a specific age class given infection by another age class.
The purpose of this study was to monitor the prevalence of Bd over time and to determine whether season and stage class influenced infection levels.
The trusts were nominated by each Strategic Health Authority on the basis of having excelled in either turnaround or 'best in class' concerning infection prevention performance in the fiscal year 2008/2009.
The five classes had varying numbers of members; the first class 'general infection' (n = 1,252, 12.5%) had a high probability of all infectious symptoms and specifically a high probability of breathlessness and wheeze symptoms compared to the other classes.
The epidemiologic characteristics were assumed to be measles-like, with a basic reproductive ratio, R0, of approximately 20, a 6-day exposed class following infection in which individuals were not infectious, and an 8-day infectious period (10).
