Fastidious Anaerobe Agar with 7% Horse Blood, Neomycin (75mg/L) & Aztreonam (2mg/L)

Fastidious Anaerobe Agar is intended as a primary isolation medium capable of supporting most clinically significant anaerobes including fastidious organisms. The formulation is complex and includes detoxification agents (starch & sodium bicarbonate) as well as growth enhancing agents (cysteine, arginine, vitamin K, sodium succinate, glucose and pyrophosphate) as well as haemin to encourage pigment production in Porphyromonas melaninogenicus . Sodium pyruvate is also included to help neutralise hydrogen peroxide. In this instance the medium is made more selective by the inclusion of neomycin and aztreonam to inhibit most enteric organisms and further enriched by the addition of 7% horse blood.
