The role of transport medium

The role of transport medium

The transport medium is a medium used for the collection, transportation and preservation of pathogenic bacteria or microbial specimens, including liquid and solid types.

Principle of Inspection

Different formulas used in different types of transport media can improve and increase the viability of the corresponding microorganisms in the specimens, so as to facilitate the short-term preservation of the specimens during transportation.

Main ingredients

The main ingredients are formulate with solvents such as sodium chloride,

potassium dihydrogen phosphate, dipotassium hydrogen phosphate, agar, and calcium chloride.

characteristic

  1. Not only can the morphology, structure and number of almost all cells be preserve, but the specimens can be preserve at room temperature for up to 6 months.
  2. The remaining cells can not only directly test for HPV, DNA, and Chlamydia, but also for gonorrhea and immunochemical tissue tests.
  3. Eliminate most germs and microbial activity within 15 minutes. Avoid possible harm to medical staff.

Instructions

  1. Before sampling, mark the relevant sample information on the label of the sampling tube.
  2. Sampling with the corresponding sampling swab.
  3. After sampling, quickly put the swab into the sampling tube.
  4. Break the swab at the breaking point of the swab and discard the tail.
  5. Tighten the tube cover tightly. Then put the sampling tube containing the sample into the biosafety bag and send it for inspection in time.

What is the transmission medium

Transport media are essentially solutions of buffers with carbohydrates, peptones and other nutrients (excluding growth factors)

designed to preserve the viability of bacteria during transport without allowing their multiplication.

The primary objective of the use of the transport medium is to maintain the specimen as near its original state as possible.

The transport medium not only protects the specimen, but also minimizes the overgrowth of bacteria from the collection to the processing of the specimen.

Depending on the type of organisms suspect in the sample, transport media may vary.

However, in general, transport media are classified on the basis of the physical state as semi-solid and liquid and also on the basis of their utility as bacterial or viral transport media.

What does transport media contain?

  • Contains only buffers and salt.
  • Doesn’t contain any nutritional ingredients such as carbon, nitrogen, and organic growth factors so as to prevent microbial multiplication.
  • Addition of antibiotics and other substances like glycerol may be add for transporting specimens for tissue culture.

What samples are collected in transport medium?

All types of samples that may contain pathogens but could not be process immediately requires a transport medium.

It may be Stool, urethral swabs, Nasal and throat swabs and specimens for tissue culture etc.

What does huachenyang produce? I guess you don’t know

Given below are some examples of transport medium with their purpose:

Cary and Blair Medium: semi-solid, white color transport medium for faeces that may contain Salmonella, Shigella, Vibrio or Cam­pylobacter

Amies medium with charcoal:

Charcoal helps eliminate metabolic products of bacterial growth, which may be especially useful in the isolation of fastidious organisms like.

However it is suggested that, some other pathogens like Campylobacter can also survive in such medium.

Amies medium without charcoal:

Are ideal for the isolation of Mycoplasma and Ureaplasma

Stuarts medium:

Commonly used for transporting specimens suspecte of having gonococci.

Also use for transporting Throat, wound and skin swabs that may contain fastidious organisms.

Venkatraman Ramakrishnan (VR) medium:

Use to transport feces from suspecte cholera patients.

Sach’s buffered glycerol saline:

Used to transport faeces from patients suspecte to be suffering from bacillary dysentery.

Viral Transport Medium:

Viral Transport Medium (VTM) is ideal for diagnosis of viral infection.

Ocular, respiratory and tissue swabs can be submit in this medium.

Fluid samples such as tracheal wash specimens or peritoneal fluid should be submit as is, in sterile vials which prevent desiccation.

In the absence of a virus transport medium, not only can the swab be placed in a sterile sealed vial, but also a few drops of saline can be added to prevent drying.

Cotton, plastic, wooden handle, polyester and other synthetic cotton swabs are all acceptable.

However, calcium alginate swabs should be avoided. Bacterial transport media are not suitable for virology.

Anaerobic Transport Medium (ATM):

It is not only a mineral salt semi-solid medium containing reducing agents, but also designed to maintain the activity of anaerobic bacteria.

It contains not only buffer mineral salts, but also sodium mercaptoacetate and cysteine to provide a reducing environment.

Resazurin may also be add as a redox indicator to reveal exposure to oxygen by turning pink.

It provides an environment that can not only maintain the viability of most microorganisms without mass reproduction, but also dilute inhibitors present in clinical materials. Examples include thioglycolate broth

VTM Swab Kit

VTM swab kit can not only be used for collection, transportation and maintenance, but also for long-term cryopreservation of virus,

Such as influenza, including H1N1, chlamydia, mycoplasma and Ureaplasma specimens.

The virus sampling tube swab box of the invention is not only convenient to use, but also can be stored at room temperature.

The kit not only contains a sampling tube for conveying medium, PP, 10ml and 3ml VTM liquid.

There is also a nasal flocking swab or throat swab.

The most important is aseptic blister packaging.
