Directions
Suspend 35.01 grams in 1000 ml purified / distilled water. Heat, if necessary, to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Cool to 45-50°C and aseptically add sterile Streptomycin to a final concentration of 30 mcg/ml of medium. Mix well and dispense as desired.
Principle And Interpretation
Littman Oxgall Broth Base was formulated by Littman (1,2). Littman Bile HiVeg™ Broth Base is used for selective enrichment of pathogenic skin fungi (dermatophytes) and saprophytic fungi from various clinical specimens. It provides effective enrichment even when the test samples are heavily contaminated with bacterial flora. Littman Oxgall media are also used for the enumeration of fungal populations of air, soil, foodstuffs and other materials of sanitary significance (3).
Littman Bile HiVeg™ Broth Base is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks. Crystal violet and Streptomycin has inhibitory effect on most of the bacteria. Synthetic detergent No. II restricts spreading of fungal colonies. The neutral pH favours the growth of many pathogenic fungi.
For inoculation, skin or nail scraping or infected hair is directly placed on the surface of Littman Bile HiVeg™ Agar Base (MV373) while sputum, faeces etc. are spread over the surface with sterile swab or the specimen are first enriched in broth and then cultured on agar medium. Whenever Nocardia asteroides, Streptomyces or any Streptomycin sensitive microorganisms are to be cultured, use the medium without Streptomycin (3).
