Brucella Agar
Use and description: The medium is recommended for the cultivation of Brucella spp. and other fastidious organisms. The medium’s nutritive value is high due to its peptone, yeast extract and glucose content. Yeast extract is a source of vitamin B complex. The medium is supplemented with vitamin K1 (10 mg/l) and haemin (10 mg/l) to favour the growth of anaerobic bacteria. It can be supplemented with 5% blood to cultivate particularly fastidious aerobic and anaerobic bacteria and for the isolation of Campylobacter in microaerophil circumstances. To overcome the problem of slow growth of Brucella spp., the following antibiotics can be added to increase selectivity and suppress the growth of contaminant organisms: polymixin, vancomycin, bacitracin and cycloheximide and nystatin.
