See the Differences At A Glance

Time and accuracy are important for managing disease outbreaks and hospital acquired infections (HAI) to make decisions that can stop the spread of disease. OpGen’s Whole Genome Maps discriminate between closely related strains, providing accurate and actionable information. Unlike traditional technologies, Whole Genome Maps can be directly correlated to sequence data—so markers for increased virulence and drug resistance can be detected early and used to characterize infections.

Pulsed Field Gel Electrophoresis Example

Traditional technologies (PFGE, ribotyping, & Rep-PCR) provide limited information and can present challenges for distinguishing closely related isolates.

Whole Genome Mapping provides high information content with the precision to discriminate closely related strains & accurately detail the genomic differences (areas in white) between isolates.

Because the maps survey thousands of locations distributed across the entire genome, more accurate structural detail is available for each strain. Whole Genome Maps are also better in capturing the insertions and genomic rearrangements that result from horizontal gene transfers; changes that are more likely to differentiate strains. And unlike pulsed-field gel electrophoresis (PFGE), Whole Genome Maps are fast, highly reproducible and relate directly to the sequence. Analyze and compare Whole Genome Maps in 24 hours to provide actionable results in an ongoing outbreak.

Map-based similarity clustering

Map-based similarity clustering accurately distinguishes strains and describes relatedness between isolates.

ALIGN: Quickly and easily track microbial contaminants and characterize outbreak strains—generate a Whole Genome Map on the reference strain and align with maps from field isolates, even with previously unsequenced or unculturable organisms.

COMPARE: With a Whole Genome Map, strain typing is fast and accurate—differences between microbial strains are easy to see, enabling health professionals to launch a rapid and confident response.

CONFIRM: OpGen’s Whole Genome Maps enable researchers to link microbial contaminants to their source and confirm outbreak strains.

 

Whole Genome Maps

Whole Genome Maps compare related Klebsiella pneumoniae isolates to quickly reveal differences (white) and similarities (blue).

“Physical map and genetic map still should be emphasized as an important parts of a reference genome. Recent progress in technologies, such as the whole genome mapping high-throughput platform offered by OpGen, now provide the tools for efficient physical map construction. This independent technology provides not only the validation of the genome sequencing, but also provides the large-scale chromosome structure information that cannot be detected by sequencing. We applied this technology as an assistant tool of the NGS to assemble bacterial, plant and large mammalian genome with reliable accuracy and generate the sub-chromosome graded assembly. The experience in these genome assembly projects shows that the physical map should be the standard for any reference genome to be assembled in further.”

“Our research focuses on a wide variety of projects from viruses and microbes to crop plants and mammals. Many of our projects are de novo assembly projects, where, without a closely related genome sequence, it can be difficult to critically assess the results. We often combine different sequencing technologies, and we are finding that regardless of the sequencing platform, error correction, or assembler used, OpGen’s Whole Genome Mapping identifies misassemblies and provides the highest quality de novo assembly for further research.”

“We adopted OpGen’s Argus System as the most advanced way of adding Whole Genome Mapping to improve whole genome sequences. We combined Whole Genome Maps with sequence assemblies to correct errors and misassemblies in bacterial genome sequences as part of our program in the Human Microbiome Project. We are now moving the technology into larger genome projects.”

“Certain things you just have a tough time answering with de novo sequencing. And assembly doesn’t always work out as sweetly as you would like. So definitely for any whole genome de novo project that people are insistent on closing we would do a Whole Genome Map optically as well as de novo assembly. And the amount of money you would save is in the thousands of dollars in finishing.”
