Littman Bile HiVegâ„¢ Broth Base ( Formerly Littman Oxgall HiVegâ„¢ Broth Base) is used for selective enrichment and cultivation of pathogenic fungi. 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. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
