Directions
Suspend 47g in 1 litre of distilled water. Bring to the boil to dissolve completely. Sterilize by autoclaving at 121°C for 15 minutes. Mix well and pour into sterile Petri dishes. For blood agar, cool to 50°C and enrich with 10% v/v sterile defibrinated blood.

Description
Brain Heart Infusion Agar may be recommended for the cultivation of streptococci, Neisseria and other fastidious organisms. Seth¹ described the use of Oxoid Brain Heart Infusion with agar for the isolation of Neisseria gonorrhoeae. Oxoid Brain Heart Infusion Agar was designed to be equivalent in performance.

The addition of blood and antibiotics makes Brain Heart Infusion Agar suitable for the isolation of the tissue phase of Histoplasma capsulatum and other pathogenic fungi, including Coccidioides immitis^2,3. For the selective isolation of fungi, without blood, cyclohexamide 0.5mg/ml and chloramphenicol 0.05mg/ml of Brain Heart Infusion Agar may be added^4,5.

Quality control

*This organism is available as a Culti-Loop®

Precautions
The medium is tested for compatibility using 7% v/v oxalated horse blood, defibrinated horse blood or defibrinated sheep blood. There should be no evidence of lysis or darkening after incubation at 37°C, 25°C or 4°C for 72 hours.
When using this medium to isolate Histoplasma capsulatum, Coccidioides immitis or other pathogenic fungi which can produce free infective spores, extreme care must be taken to avoid dissemination of infective particles in the laboratory. The cultures should be examined only in a closed, filtered air cabinet.

This medium is unsuitable for the screening of vancomycin resistant enterococci (VRE). More suitable and superior media for the screening of VRE are available; Brilliance VRE PO1226A or Remel BHI with Vancomycin RO1176.
