Area of Science:
- Microbiology
- Genomics
- Infectious Diseases
Background:
- Shigella flexneri is a significant pathogen causing shigellosis, a severe diarrheal disease.
- Shigellosis represents a substantial public health concern, accounting for 18% of cases in the United States.
- Understanding the genetic makeup of reference strains is crucial for accurate diagnostics and therapeutic development.
Purpose of the Study:
- To provide a high-quality genome assembly of the Shigella flexneri ATCC 12022 strain.
- To establish a genomic resource for the S. flexneri reference strain.
- To support research into the pathogenesis and control of shigellosis.
Main Methods:
- Whole-genome sequencing of Shigella flexneri ATCC 12022.
- Bioinformatic analysis for genome assembly.
- Scaffold-based genome construction.
Main Results:
- A comprehensive genome assembly of 4.51 Mbp was generated.
- The genome was resolved into 10 distinct scaffolds.
- This represents a significant advancement in the genomic characterization of this reference strain.
Conclusions:
- The genome assembly of S. flexneri ATCC 12022 provides a valuable resource for the scientific community.
- This genomic data will facilitate further studies on S. flexneri virulence and antimicrobial resistance.

Genome Annotation and Assembly
16.5K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Bacterial Gastroenteritis
74
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Oligosaccharide Assembly
2.6K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
