New Positive Validation Data for DNA Extraction Kit Announced

The UK genomic tools developer, RevoluGen Ltd, has announced new data validating the performance of its high-molecular weight (HMW) DNA extraction kit, Fire Monkey. Scientists at the UK’s Quadram Institute together with collaborators in Pakistan have published positive results from Illumina whole genome sequencing (WGS) for extensively drug-resistant (XDR) Salmonella Typhi characterisation in Pakistan, using Fire Monkey.

Salmonella Typhi are bacteria which infect the intestinal tract and the blood, causing typhoid fever. In 2016, an outbreak of a strain of the bacteria resistant to many of the usual antibiotics used to treat the disease (XDR S. Typhi) was reported in the Sindh province of Pakistan. Further spread of the outbreak is of serious concern due to the limited options for treatment. The research involving scientists at the Quadram Institute identified 27 XDR S. Typhi isolates from patients at Jinnah Hospital in Lahore, the capital of the Pakistani province of Punjab, between January and April 2019. All isolates were of the same genotypic background as the outbreak strain from Sindh province, as confirmed by Illumina whole genome sequencing. Importantly the first emergence of XDR S. Typhi in Punjab province was confirmed by this whole genome sequencing and analysis.

“We have found Fire Monkey to be very quick and easy to work with. We are now keen to take advantage of its step-change in length of DNA fragments, thus enabling multiplexed long-read sequencing. We look forward to continuing our relationship with RevoluGen to explore the role of its technology in metagenomic analysis and to explore automation” commented Dr Gemma Langridge, Group Leader, Quadram Institute.

Pieter Haitsma Mulier, CEO of RevoluGen commented: “Microbial sequencing is now becoming routine and provides an important tool for disease surveillance, accurate and rapid diagnosis, as well as for monitoring and profiling antibiotic resistance. This publication from the Quadram Institute provides key validation of Fire Monkey/ Fire Flower for use in this field.”
