Microbiological samples - these are specimens collected for the purpose of
studying microorganisms. They are collected in specific containers hence
ensures accurate testing and analysis.
Role: clinical diagnostics, food safety, environmental monitoring, and
research.
Examples: serum, virology, biopsy tissue, CSF and urine samples.
3. 1) Viral transport media
Used for transporting samples containing viruses (e.g., SARS-CoV-2).
VTM maintains virus viability during transit.
Typically contains buffers, proteins, and antimicrobial agents.
Ensures accurate diagnostic testing.
4. 2) Bacterial transport media
Preserves bacterial viability without allowing multiplication.
Commonly used for swabs, urine, and fecal samples.
Examples include Amies transport medium and Stuart’s transport medium.
5. 4) Fecal transport systems
Designed for stool samples.
Keep anaerobic and aerobic bacteria stable.
Cary-Blair medium is commonly used.
6. Urine transport systems
Maintain urine sample integrity.
Prevent bacterial overgrowth.
Examples include boric acid tubes.
7. 5) Saliva collection kits
Used for collecting saliva samples.
Stabilize nucleic acids (DNA, RNA) for molecular testing.
Essential for diagnostics, including SARS-CoV-2 testing.
