Ray of Acolyte shines against disease

Ten years of research at Porton Down has enabled Acolyte Biomedica to develop an automated system to diagnose bacterial infections such as pneumonia and meningitis and explore their drug susceptibility in record time.

Acolyte is a joint venture between Dstl and international technology group ANGLE Technology, with finance from BioProjects International.

Development house Cambridge Consultants Limited (CCL) has been involved too, designing a high throughput testing machine that uses a combination of three Dstl technologies:

  • advanced bioluminescent detection technology – the key to the rapid diagnosis
  • immuno magnetic separation (IMS) technology
  • antibiotic susceptibility testing (AST).

Speedier diagnosis and treatment means:

  • better patient recovery as suitable antibiotics are prescribed earlier
  • reduced risk of the infection spreading
  • less potential for multi-drug resistant bacteria such as MSRA to thrive since the test quickly pinpoints the most effective antibiotics.

Dr Bill Mullen, Acolyte’s business development director predicts that the Acolyte instrument will slash health care costs through targeted treatment, ending the current ‘hit and hope’ approach.

“There will also be an impact on the emergence of multi-drug resistant strains of bacteria – the right drug for the right bug,” he says.

Hugh Ballantine Dykes, biotechnology marketing manager for Dstl, said: “Dstl has a wealth of first-rate scientific knowledge, which has benefits far beyond the military field. Acolyte demonstrates that Dstl’s expertise in biotechnology can be combined with technology management and finance to provide a winning formula with great benefits to the health service.”

Chris Hammond, head of CCL’s healthcare engineering added: “Automation of microbiological testing is overdue. By combining Acolyte’s technology and CCL’s rapid product development expertise, ultra-rapid microbiological detection will soon be a reality and bring all the associated benefits.”

Getting technical
Advanced bioluminescent detection technology

This ultra-sensitive technology developed by Dstl can detect bacterial cells in minutes, compared to current methods requiring 18 to 36 hours to identify target bacteria.

Immuno Magnetic Separation

A technique in which a positive sample is mixed with antibody-coated magnetic beads to extract the target bacteria.

Antibiotic Sensitivity Testing

The advanced bioluminescent technology can speed detection of bacteria susceptibility to various antibiotics, allowing the right treatment to be prescribed first time.
