Overview

The primary purpose of bacterial genome de novo assembly and annotation is to obtain a complete and accurate genetic blueprint of a bacterial isolate. This is essential for: 1) Identifying the exact species and strain of bacteria, especially in cases where conventional methods are inconclusive. 2) Detecting antimicrobial resistance genes, guiding effective antibiotic therapy. 3) Understanding virulence factors and pathogenic mechanisms. 4) Conducting epidemiological surveillance and outbreak tracking. 5) Supporting research in bacterial evolution and comparative genomics. 6) Facilitating the development of novel diagnostics, vaccines, and therapeutics. By providing a comprehensive genomic map, this test empowers clinicians and researchers with actionable insights for improved patient outcomes and public health interventions.

How to Prepare

  • For culture isolates: Use a sterile loop to transfer 1-2 colonies into a sterile tube containing transport medium.
  • For clinical specimens: Collect in a sterile container as per standard protocols (e.g., blood in EDTA tube, sputum in sterile cup).
  • Label the sample with patient name, ID, and date of collection.
  • Maintain cold chain if transport time exceeds 2 hours.

Understanding Your Results

The results of bacterial genome de novo assembly and annotation provide a comprehensive genetic profile of the bacterial isolate. Interpretation should be performed by a qualified geneticist or infectious disease specialist in the context of clinical findings and other laboratory data.
📊

High N50 and low contig count indicate a high-quality assembly, suitable for downstream analysis. Poor assembly may require resequencing.

📊

Presence of resistance genes suggests potential resistance to corresponding antibiotics. This should be correlated with phenotypic susceptibility testing.

📊

Detection of virulence genes indicates pathogenic potential. The specific genes present can inform on the severity of infection and clinical management.

📊

The assigned sequence type helps in epidemiological tracking and outbreak investigations. Certain STs may be associated with high-risk clones.

⚠️ When to Consult a Doctor:

If you have symptoms of a bacterial infection (fever, pain, swelling, etc.) or if you have been advised this test by a healthcare provider, consult your physician for proper clinical correlation and management. Do not self-interpret results.

Limitations

  • De novo assembly may not resolve repetitive regions or plasmids completely
  • Annotation accuracy depends on existing databases and may miss novel genes
  • Results are for research and clinical guidance; not a standalone diagnostic test
  • Requires a pure bacterial culture for optimal results; direct clinical specimens may have lower sensitivity

Risks & Considerations

  • No significant risks are associated with this test as it is performed on a sample collected by standard procedures.
  • If a blood sample is taken, there is a minimal risk of bruising or infection at the puncture site.

Interfering Factors

  • Contamination of the bacterial culture with other organisms
  • Insufficient quantity or poor quality of DNA
  • Presence of PCR inhibitors in the sample
  • Mixed bacterial populations
  • Incomplete sequencing coverage due to technical issues

Frequently Asked Questions

What is bacterial genome de novo assembly and annotation?
It is a process that determines the complete DNA sequence of a bacterium and identifies all its functional elements, such as genes, regulatory regions, and resistance markers. This is done by sequencing the DNA, assembling the reads into a complete genome, and annotating the genome to locate genes and other features.
What is the cost of this test at DNA Labs India?
The test costs Rs 18000, which includes DNA extraction, library preparation, Illumina sequencing, de novo assembly, annotation, and a detailed report. Free home sample collection is available for online bookings.
What is the turnaround time for results?
Reports are typically delivered within 4 weeks from the date of sample receipt.
What sample is required for this test?
A pure bacterial culture isolate (1-2 colonies) or a clinical specimen such as blood, sputum, or urine, as advised by your physician. The sample should be collected in a sterile container.
Is fasting required before the test?
No, fasting is not required for this test.
Can this test detect antimicrobial resistance?
Yes, the annotation identifies genes associated with antimicrobial resistance, which can guide treatment decisions. However, results should be correlated with phenotypic susceptibility testing.
Is home sample collection available?
Yes, we offer free home sample collection for online bookings across major cities in India, including Mumbai, Delhi, Bangalore, Hyderabad, and many more.
How should the sample be transported?
The sample should be transported to the lab as soon as possible. For culture isolates, keep at 2-8°C. For clinical specimens, maintain cold chain if transport exceeds 2 hours.
What is the difference between de novo assembly and reference-based assembly?
De novo assembly builds a genome from scratch without a reference, making it ideal for novel organisms. Reference-based assembly maps reads to a known reference genome, which is faster but may miss novel sequences.
Can this test be used for outbreak investigations?
Yes, the high-resolution genomic data can be used for epidemiological tracking, identifying transmission routes, and understanding outbreak dynamics.
Are there any risks associated with this test?
No significant risks are associated with this test. If a blood sample is taken, there is a minimal risk of bruising or infection at the puncture site.
How should I interpret the results?
Results should be interpreted by a qualified healthcare professional. The report includes information on genome quality, gene content, resistance genes, and virulence factors, which can be used for clinical and research purposes.
