Bacteraemias caused by gram negative rods are now the most common type seen in NHS hospitals, and their incidence is increasing. The major proportion of these infections is accounted for by Escherichia coli bacteraemias. However Klebsiella pneumoniae and Pseudomonas aeruginosa are becoming increasingly significant also.
Gram negative rods look identical under the light microscope after gram staining and further identification to species by culture methods can take 24-48 hours. Compared to enterobacteria such as E.coli, P. aeruginosa is relatively resistant to many antibiotics, so positive species identification is needed to make an informed treatment decision.
Gram-Negative QuickFISH allows clinicians to rapidly ensure early, appropriate therapy for patients with Pseudomonas bacteraemia, while minimising the unnecessary use of aggressive and broad spectrum antibiotics.
