Uncommon pathogens involved in bacteraemia: England, Wales and Northern Ireland: 2003-2007

This review covers bacteraemia reports from laboratories in England, Wales and Northern Ireland identified from blood samples from 2003-2007. The reports were made to HPA under the voluntary reporting scheme which covers both community-acquired and hospital-acquired bacteraemias. For the purposes of this report 'uncommon pathogens involved in bacteraemia' means organisms from genera with fewer than 50 bacteraemia reports in each year.

Due to the small number of reports of uncommon pathogens, details such as a recent travel history, use of an intravascular line or a history of recent surgery are not examined further here.

In 2007, a total of 3,405 reports were made of uncommon pathogens in 116 genera. Organisms from Bacteroides spp, Clostridium spp and Streptococcus spp. were the most frequently reported. A full list of all organisms with fewer than 50 reports per year is given in table 1.

For some organisms it was apparent that serum samples for antibody and antigen detection had been recorded as blood samples. All organisms that had a 'parent specimen type' of blood that were identified by antibody or antigen detection alone were removed from this report.

Discussion

The purpose of this review is to cover the unusual bacterial genera that have not been discussed in the other bacteraemia reports in the HPR this year. Although these bacteria only account for approximately 3.1-3.5% of the total bacteraemia reports between 2003-2007, they can be associated with important clinical consequences. For example, some genera, such as Cardiobacterium spp., Eikenella spp. and Kingella spp. can be associated with endocarditis [1].

These reports should reflect clinically significant disease. It can be difficult, however, to distinguish true clinical bacteraemias and contamination of cultures can lead to the diagnosis of a pseudobacteraemia [2, 3]. For example, Ralstonia picketii is a rare bacteraemia [4], and this organism has previously been identified as a source of pseudobacteraemias, suggesting further investigation may be recommended if R. picketii is identified in blood culture [5]. In 2003 there were 11 reports of bacteraemias due to R. picketii which increased by a small margin in subsequent years. Molecular tools have improved the detection of the more unusual bacteria from blood and such methods have allowed the identification of new agents of severe disease such as endocarditis, however the nature of these methods requires that great care must be taken to avoid reporting contaminants [1, 5, 6].

As noted above, a number of reports for certain organisms referred to antibody detection, rather than blood culture. This is of concern as it may lead to an exaggeration of the number of bacteraemia reports. Reports of bacteraemias based on antibody- or antigen detection have been removed from this report.

These uncommon organisms have been reported in previous analyses available on the HPA website [7] and feedback is welcome. If confirmation of unusual bacterial pathogens is required, isolates can be sent to the Laboratory of Healthcare Associated Hospital Infection, Specialist and Reference Microbiology Division, HPA Colindale, London.

Acknowledgments

These reports would not be possible without the enduring weekly contributions from microbiology colleagues in laboratories across England, Wales and Northern Ireland, without which there would be no surveillance data. Please send any comments/feedback to hcai.amrdivision@hpa.org.uk. In addition, the support from colleagues within the HPA Centre for Infections, is valued in the preparation of the reports. These contributions are greatly appreciated.
