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?
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.
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 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

used the disposable sampling swabs to extract secretions from natural cavities such as oral cavity and nasopharynx，
The nasopharyngeal swab consists of nylon short fiber wool and medical ABS plastic rod.
The role of nylon short fibers is similar to a soft brush,Not only can effectively improve the collection of cell materials，
The capillary movement between the fibers creates a powerful hydraulic pressure and can also absorb liquid samples.
At the same time, the sample is close to the surface of the swab and is easily eluted for easy inspection.
Enough cervical epithelial exfoliated cells can be collected and used in detection methods such as human papillomavirus (HPV) nucleic acid detection,
thereby assisting clinical judgments on the risk and type of the subject.
③. Virus and bacteria sampling swab
Nylon flocking swabs have a better collection and transportation effect for the collection of viruses and bacteria,
especially for those specimens that cannot be submitted for inspection in time and placed for too long.
By wiping blood, epidermis and other tissues, it not only effectively contacts the samples that need to be collected for DNA testing,
and makes the DNA test results more accurate, but also effectively avoids the mixing of other magazines and affects the test results.
⑤. Sterile swabs for cell sampling
The fluffy texture can not only collect more target analytes, but also has no sample residue,
which can speed up the sample processing speed.
The fluffy texture can not only collect more target analytes, but also has no sample residue.
