Directions
Suspend 42.3 grams in 900 ml purified/distilled water. Mix well to dissolve the medium completely. Sterilize by filtration and aseptically add 100 ml sterile Horse Serum (RM1239) and 1,000,000 units Penicillin and 0.25 gram Thallium acetate. Mix well and dispense into sterile tubes or flasks as desired.
Principle And Interpretation
Genus Mycoplasma belongs to the class Mollicutes characterized by absence of cell wall, small genome and low G + C content, and were first recognized from a case of pleropneumonia in a cow (1). The organism was designated “pleuropneumonia-like organism”, or PPLO.
For the cultivation of Mycoplasma the medium ingredients and all the supplements should be free of any toxic substances even in small amounts. Mycoplasma Synoviae HiVeg™ Medium Base is prepared by completely replacing animal based peptone with vegetable peptones to avoid BSE/TSE risks associate with animal peptones. HiVeg™ special infusion, HiVeg™ infusion and HiVeg™ peptone No. 3 provide nitrogen, vitamins, amino acids and carbon sources. Sodium chloride maintains the osmotic balance. Many Mycoplasma require serum for their good growth and also presence of antibiotic is necessary to prevent the growth of contaminating organisms. Mostly the Mycoplasma species are aerobic or facultatively anaerobic but some are microaerophilic. Few are anaerobic saprophytic Mycoplasma which grow best at 22-35°C while pathogenic strains grow at 35°C. Mycoplasma Synoviae HiVeg™ Medium Base contains yeast autolysate which is a rich source of Nicotinamide Adenine Dinucleotide (NAD) required by Mycoplasma synoviae. HiVeg™ special infusion and HiVeg™ infusion along with the HiVeg™ peptone No. 3 provide organic nitrogen, carbon, sulphur, vitamins and trace elements. Tris buffer and disodium phosphate buffers the medium. Horse serum provides growth factors including lipid compounds to Mycoplasma. TTC helps to identify TTC reducing Mycoplasmas (2). Penicillin and thallium acetate are added to the medium to inhibit bacterial growth.
Type of specimen
Please add specimens.
Specimen Collection and Handling:
After use, contaminated materials must be sterilized by autoclaving before discarding.
Warning and Precautions :
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 specimens. Safety guidelines may be referred in individual safety data sheets.
Limitations :
- Since Mycoplasma species are aerobic or facultatively anaerobic but some are microaerophilic, proper incubation should be carried out for optimal recovery.
- Few are anaerobic saprophytic Mycoplasma which grow best at 22-35°C while pathogenic strains grow at 35°C, hence growth conditions must be maintained.
- Since the medium is highly enriched care must be taken during innoculation to avoid contamination.

Storage and Shelf Life
Store between 10-30°C in a tightly closed container and the prepared medium at 20-30°C. Use before expiry date on the label. On opening, product should be properly stored dry, after tightly capping the bottle in order to prevent lump formation due to the hygroscopic nature of the product. Improper storage of the product may lead to lump formation. Store in dry ventilated area protected from extremes of temperature and sources of ignition. Seal the container tightly after use. Product performance is best if used within stated expiry period.
Disposal
User must ensure safe disposal by autoclaving and/or incineration of used or unusable preparations of this product. Follow established laboratory procedures in disposing of infectious materials and material that comes into contact with sample must be decontaminated and disposed of in accordance with current laboratory techniques (3,4).
