Directions
Using the capped swab, provided along with the media containing tube, collect the sample to be transported. Discard the cap of the tube and insert the capped swab with the sample till the bottom of the medium. Tighten the cap firmly. The specimen will be preserved during transportation and also the viability of the organisms will be maintained but it will diminish over the time. Some growth of contaminants may occur during longer period of transport. After the transportation, the specimen should be inoculated in proper medium as soon as possible. The cultures on transport swabs must not be kept at room temperature for more than 24 hours.
Principle And Interpretation
Effective recovery of microorganisms and its identification is dependent on a number of factors such as collection and transportation to the laboratory under conditions which allow maintenance of viability. Amies transport medium w/ charcoal is a modification of Stuarts Transport Medium (1,2,3,4). The medium gives improved recovery of Neisseria gonorrhoeae due to presence of charcoal in the medium. Charcoal neutralizes the toxic effects of material that may hamper growth of pathogens. Addition of inorganic phosphate buffer and sodium chloride make this medium different from stuarts transport medium. Calcium and magnesium salts control the permeability of bacterial cells. Presence of sodium thioglycollate and small amounts of agar provide a reduced environment. Sterile cotton swabs allow absorption of specimen material while polylpropylene shaft allows semiflexibility to the swab stick, aiding in collection.
Type of specimen
Clinical samples - Throat, Vaginal secretions, Wound swabs, etc.
Specimen Collection and Handling
For clinical samples follow appropriate techniques for handling specimens as per established guidelines (5,6).
After use, contaminated materials must be sterilized by autoclaving before discarding.
Warning and Precautions
In Vitro diagnostic Use only. For professional use only. Read the label before opening the container. Wear protective gloves/protective clothing/eye protection/ face protection. Follow good microbiological lab practices while handling specimens and culture. Standard precautions as per established guidelines should be followed while handling clinical specimens. Safety guidelines may be referred in individual safety data sheets.
Limitations
- Further recovery from this enriched medium onto selective media is required.
- The medium should be kept cool but do not freeze.
- Further biochemical identification is necessary for confirmation.
