Objectives:
Determination of causes, trends, and
antibiotic resistance in reports of bacterial pathogens isolated from
blood in England and Wales from 1990 to 1998.
Design:
Description of bacterial isolates from blood, judged to be clinically significant by microbiology staff, reported to
the Communicable Disease Surveillance Centre.
Setting:
Microbiology laboratories in England and Wales.
Subjects:
Patients yielding clinically significant
isolates from blood.
Main outcome measures:
Frequency and Poisson
regression analyses for trend of reported causes of bacteraemia and
proportions of antibiotic resistant isolates.
Results:
There was an upward trend in total numbers of
reports of bacteraemia. The five most cited organisms accounted for
over 60% of reports each year. There was a substantial increase in the
proportion of reports of Staphylococcus aureus resistant to methicillin, Streptococcus pneumoniae resistance to
penicillin and erythromycin, and Enterococcus faecalis
and Enterococcus faecium resistance to vancomycin. No
increase was seen in resistance of Escherichia coli to gentamicin.
Conclusions:
Reports from laboratories provide
valuable information on trends and antibiotic resistance in bacteraemia and show a worrying increase in resistance to important antibiotics.
