Directions
Label the ready to use LQ525IXB bottle. Inoculate 50-100 cfu sample and Incubate at specified temperature and time.
Principle And Interpretation
T.A.T. Broth is prepared according to the formula recommended by United States Food and Drug Administration (1) for enrichment and further isolation and cultivation of gram-negative bacteria in cosmetics, tropical drugs and in the sterility testing of viscous or gelatinous substances. It is especially adapted for the testing of cosmetics.
Cosmetics and pharmaceutical products are subject to contamination during manufacturing and subsequent use by consumers (4). Preservatives are used in aqueous products to make them self-sterilizing for vegetative bacteria, yeasts and moulds, and bacteriostatic or bactericidal for spores (4). Tryptone provides the nitrogen, vitamins, amino acids and carbon in T.A.T. Broth Base. Azolectin and polysorbate 20 neutralize preservatives in the cosmetics or pharmaceutical products, allowing bacteria to grow.
Type of specimen
Pharmaceutical and Cosmetics samples for sterility testing.
Specimen Collection and Handling
Prepare decimal dilutions of the sample to be tested from 10-1 to 10-6. Inoculate 1 gram (1 ml) sample and 1 ml of each dilution into 40 ml of T.A.T. Broth (5). After incubation, subculture the growth on MacConkey Agar (MP081) and TSI Agar (M021). 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 :
- 1. Further biochemical and serological tests must be carried out for further identification.
