An evaluation of the relative importance of host and pathogen factors on the survival rate of patients with invasive Streptococcus pyogenes infection found a number of clinical and demographic factors to be associated with risk for death. Some evidence suggested a seasonal pattern to patient survival rate.

Methods: A prospective study involving 16 hospital microbiology laboratories in London and South-East England was undertaken over a 12 week period. Each laboratory submitted up to 100 consecutive cephalosporin-resistant Enterobacteriaceae isolates judged clinically significant by microbiology staff.
Objectives: To describe the current patterns of antimicrobial resistance in the major pathogens of bacteraemia in the UK and Ireland, to highlight any unexpected resistance patterns and to act as a reference baseline for future studies.
Methods: In 2001 and 2002, 5092 blood culture isolates were collected by 29 laboratories distributed across the UK and Ireland. A single central laboratory re-identified the isolates and measured MICs by the BSAC agar dilution method.
Objectives: To assess ciprofloxacin resistance among Escherichia coli isolates from bacteraemia patients in England in relation to age, sex and Region.
Methods: Routine susceptibility data for bacteraemia isolates were collected from over 90% of hospitals in England.
Results: During 1995-2001, the prevalence of ciprofloxacin resistance trebled, from 2.
