GcoGSA-BA: a global core genome SNP analysis for Bacillus anthracis
Health Security
|March 28, 2015
Summary
This study introduces GcoGSA-BA, a bioinformatics pipeline for identifying Bacillus anthracis origins from sequencing data. It distinguishes bioterrorism agents from environmental contamination and detects anthrax toxins without advanced genomics expertise.
Area of Science:
- Bioinformatics
- Genomics
- Microbiology
- Biosecurity
Background:
- Distinguishing between bioterrorism agents and environmental contamination is crucial for biosecurity.
- Accurate identification of Bacillus anthracis origins is essential for public health and safety.
Purpose of the Study:
- To develop an accessible analytical pipeline for inferring the phylogenetic position of Bacillus cereus group species, including B. anthracis.
- To enable detection of the anthrax plasmid pXO1 and its associated toxins.
- To facilitate the identification of suspected anthrax isolates within the B. cereus group.
Main Methods:
- Development of the GcoGSA-BA analytical pipeline.
- Utilizing next-generation sequencing reads for phylogenetic analysis.
- Incorporating detection of the anthrax plasmid pXO1 and toxin genes (lethal factor, edema factor, protective antigen).
Main Results:
- The GcoGSA-BA pipeline successfully infers the phylogenetic position of Bacillus cereus group species.
- The pipeline accurately detects the presence of the anthrax plasmid pXO1.
- It can identify isolates carrying anthrax toxins within the B. cereus group.
Conclusions:
- GcoGSA-BA provides a user-friendly tool for phylogenetic analysis of Bacillus cereus group species.
- This pipeline aids in distinguishing between bioterrorism agents and environmental contamination.
- It enhances biosecurity by enabling rapid detection of Bacillus anthracis and associated toxins.

Genome-wide Association Studies-GWAS
17.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains.

Genomic DNA in Prokaryotes
51.2K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Genomic DNA in Eukaryotes
54.5K
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Evolution of Microbial Genome
60
Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.

Single Nucleotide Polymorphisms-SNPs
20.2K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
