Scientists develop new ways to detect E. coli

Scientists develop new ways to detect E. coliScientists from Shenzhen have created and released a third version of a assembled genome of a deadly new E. coli strain and diagnostics kits to quickly identify a highly infectious bacterium. The Beijing Genomic Institute Shenzhen and researchers from the University Medical Center Hamburg develop the new genome.

The university provided a more complete genome map and corrected any assembly errors that were found in the previous versions of the strain. The new version is completely de novo assembly while the previous versions that were used by the institute was using a reference based assembly method in obtaining a sequence.

The new assembly will continue to support the finding of infectious strains that carries the disease causing genes from two different types of pathogenic E. coli namely enteroaggregative E. coli and the enterohemorrahagic E coli. The institute and the Beijing institute of microbiology have developed a PCR diagnostic protocol for identifying the strain. Results then can be obtained in two or three hours after receiving the samples.
