Identifying infections faster
Current diagnostic techniques
IN THE microbiology laboratory, the identification of bacterial or yeast isolates is currently based on phenotypic characteristics such as growth on selective and non-selective media, colony morphology, Gram stain and various biochemical reactions.
Although the results of Gram staining can be achieved within minutes, complete identification usually takes one or more days. In addition, tests may be difficult to interpret, require specialised staff, or be inconclusive.
Recent molecular methods for microbial identification have been introduced, such as real-time PCR and target DNA sequence analysis; however, these methods do not provide the complete solution to bacterial identification. To optimise care of patients with infectious diseases there is an urgent need for rapid, simple techniques for microbial identification.
