transport medium

transport 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.

Transport medium aims to preserve a specimen and minimize bacterial overgrowth from the time of collection to the processing of the specimen. Depending on the type of organisms suspected 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 added 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 processed immediately requires a transport medium. It may be Stool, urethral swabs, Nasal and throat swabs and specimens for tissue culture etc.

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

Cary and Blair Medium: semi-solid, white colored 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 suspected of having gonococci. Also used for transporting Throat, wound and skin swabs that may contain fastidious organisms.
Venkatraman Ramakrishnan (VR) medium: Used to transport feces from suspected cholera patients.
Sach’s buffered glycerol saline: Used to transport faeces from patients suspected 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 submitted in this medium. Fluid samples such as tracheal wash specimens or peritoneal fluid should be submitted as is, in sterile vials which prevent desiccation. In the absence of viral transport medium, submit swabs in sterile, sealed vials with several drops of saline added, to prevent desiccation. Cotton, plastic, wood-handled, and Dacron and other synthetic swabs are all acceptable. Calcium alginate swabs should be avoided. Bacterial transport media are not appropriate for virology.
Anaerobic Transport Medium (ATM): is a mineral salt base semi-solid media with reducing agents designed as a holding medium for maintaining the viability of anaerobic bacteria It contains buffered mineral salts in a semi-solid media with sodium thioglycolate and cysteine added to provide a reduced environment. Resazurin may also be added as a redox indicator to reveal exposure to oxygen by turning pink. It provides an environment, which maintains the viability of most microorganisms without significant multiplication and allows for dilution of inhibitors present in clinical material. Examples include thioglycolate broth

What’s the use of disposable sampling swabs

What’s the use of disposable sampling swabs

Disposable sampling swabs are suitable for the collection of microorganisms.

They are not only helpful for the detection of viruses or research of virus samples in hospitals or laboratories,but also can be used for biological samples of human or animal natural cavities,

such as throat, nasal cavity, oral cavity, vagina and other parts.

It can also be used for the detection of human oral or nasal diseases.

It is necessary to collect oral epidermal cells or nasal virus samples with a sampling swab,

and save the cells or samples in the collection tube, and then transfer them to the laboratory for detection.

Here is an example of nasal swab sampling

Nasal swab operation cases:

① Ask the patient’s head to keep still and remove the secretion from the surface of the anterior nostril;

② Gently and slowly insert the swab into the nasopharynx through the nasal cavity;

③ When encountering resistance, they arrive at the posterior nasopharynx and stay for several seconds to absorb secretions;

④ Take out the swab gently and put it in the transport medium;

⑤ For the swab used for virological test,

immerse the head of the swab into the virus carrier solution,

discard the tail, and tighten the tube cover;

⑥ Return the swab to the sampling device or suitable transfer device

The characteristics of Hua Chenyang disposable swabs were as follows

① It is made of non inhibitory DNA amplification material,

which can be verified by direct PCR amplification, and the extraction step is omitted.

② .In order to keep the swab clean and free from contamination, we use the monomer independent packaging

③ No DNA enzyme and human DNA can be amplified.

④ The tube body is transparent and the inspection material is visible.

⑤ The unique casing design ensures the air circulation in the casing,

prevents the inspection materials from mildew due to the humid sealing environment,

and avoids the magazine pollution in the external air, thus affecting the inspection quality.

Advantages of flocking cotton swabs


Flocked nylon swabs: excellent sample collection / release capacity, release rate > 80%

Routine fiber swabs: 1

The sample will be intercepted in the gap of fiber mass, that is, the sample permeates, dilutes and intercepts in the fiber. Slow acquisition, slower release.

The sampling time of flocking swab is 3-5 seconds, while that of cotton swab is 15-120 seconds or even longer, which causes pressure on the staff during the diagnosis process. Only faster sample extraction can complete the collection and analysis more efficiently.

Effects of huachenyang flocking swabs and composite nano cotton swabs on DNA extraction from microbial samples:

① Methods three kinds of carriers (glass, slotting knife and drawer handle) were selected for disinfection, and the trace DNA samples on the carrier surface were simulated.

② The DNA on the carrier was extracted with the flocking swab and the composite nano cotton swab respectively.

③ The number of STR genotypes, the number of alleles lost and the area of peak height were used as the comparison indexes of extraction effect.


*Five microdna samples were successfully detected in huachenyang flocking swab group, and 4 samples were detected effectively;

*Nine microdna samples were detected effectively in the composite nanocotton swab group;

*The number of allele loss in the cotton swab extraction group was significantly more than that in huachenyang Elaine group, and the peak height area was significantly lower than that in huachenyang group.


*In this study, the effect of Zhonghua Chenyang flocking swab on DNA extraction of fingerprints on glass surface, exfoliated cells on cutting surface and cells on drawer handle surface was significantly better than that of composite nano cotton swabs.

Characteristics of huachenyang flocking swabs

Huachenyang medical uses the technology of spray dense planting nylon fiber

According to the analysis items, there are soft or brush like swabs, which have reached the maximum collection

The world’s only disposable sterile injection swab with breaking point

The technology of flocking cotton swab can improve the adsorption / release amount and the sensitivity of analysis.

No sample rejection indicates faster and less specimen transfer

The upright nylon fiber is like a soft brush, which can collect more cell samples. The capillary interaction between nylon fibers enhances the loading capacity of water-based samples, and the samples are concentrated on the surface of the swab, which is easier to elute. Nylon nasopharyngeal swab can absorb and release more samples.

Why Flocked Swabs Provide Superior Specimen Collection

Why Flocked Swabs Provide Superior Specimen Collection

Flocked swabs mark the newest evolution of single-use specimen collection devices.

Flocking refers to the multi length fiber (called flocking);

For adhesive coating surface;

To enhance the sample collection process.

All flocked swabs have definite advantages for many applications. Flocked Swabs Provide Optimum Sampling
Flocked swabs are an excellent choice for use with rapid diagnostic tests because of their ability to better collect cells or organisms at the collection site and rapid release of entire cells.

iClean® flocked swabs have been patented for their unique manufacturing process which allows for much higher sample yield.

Enhanced Diagnostic Sensitivity

Patented flocking technology turns every fiber into a velvet brush;

So as to create hundreds of thousands of contact points;

In order to better collect and release samples.

The increased number of target cells (compared to non-flocked swabs) help to improve sensitivity of rapid diagnostic tests.

Rapid Elution

HUACHENYANG’s iClean® flocked swabs are fully integrated with the handle (meaning they contain no inner fabric or other inner core to absorb the specimen), a larger amount of specimen is collected and retained. Not only does this provide for better sample yield, it also allows a more rapid and complete release of the sample into liquid media.

Proprietary Multi-Length Flock Fibers

Puritan isn’t the only medical products supplier to offer flocked swabs. But we are the only company that makes iClean® swabs with proprietary multi-length flock fibers. Puritan’s proprietary multi-length flock fibers create a web-like structure that collects and retains more specimen than traditional cotton, polyester or rayon swabs.

Convenient Handling and Transport

Our PurFlock iClean® flocked swabs are available with pre-molded breakpoints, with printed indicators, so you can easily break the handle before attaching the cap to the vial. Sterile iClean® swabs are available in dry transport tubes and medium filled transport tubes. After sampling, simply replace the top portion of the tube for trouble-free transport.

What are Flocked Swabs?

iClean’s flocked swabs comprise of a solid molded plastic applicator shaft with a tip that can vary in size and shape. The tip of the applicator is coated with short Nylon fibers that are arranged in a perpendicular fashion. This perpendicular arrangement results from a process called flocking, where the fibers are sprayed onto the tip of the swab, while it is held in an electrostatic field. The process creates a highly absorbent thin layer with an open structure. 

Features of throat swab products:

1. A release rate of more than 90% for the collected samples;

2. It can be operated with one hand to avoid pollution and is convenient to use;

3. Ethylene oxide sterilization, independent packaging;

4. Unique technology, increase the comfort of the collected person;

5. Under normal temperature conditions, samples can be stored for 12 months;

6. Throat swab The swab set is a combination of swab and preservation solution, which cooperates with one time/person to collect swab samples.
