Brucella broth base

Brucella Broth Base is anutrient-rich culture medium formulated to support luxuriant growth of avariety of fastidious bacteria, including Brucella species, Streptococci,Pneumococci, Listeria, Neisseria meningitidis, and Haemophilus influenzae. The medium contains peptic digest of animal tissue and casein enzymic hydrolysate as sources of organic nitrogen. Yeast extract provides essential vitamin B complex, while dextrose serves as the carbohydrate source. Sodium chloride maintains osmotic balance, and sodium bisulfite is included toenhance bacterial growth.

Brucella Broth Base is widelyused in clinical microbiology and research laboratories for cultivating andisolating fastidious pathogenic bacteria such as Brucella and otherrelated organisms. It is suitable for diagnostic purposes, antimicrobialsusceptibility testing, and research requiring robust growth of these bacteriaunder controlled lab conditions in clinical microbiology, food and beverageindustries.

Suspend 14.05 g of Brucella Broth Base in 500 ml of distilled water. Heat to boiling 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 5% v/v heat inactivated (H1138) horse serum. Add polymyxin B (2,500 IU, Cat. No. 81334), bacitracin (12,500 IU, Cat. No. 11702), nystatin (50,000 IU, Cat. No. 74721), cycloheximide (50mg, Cat. No. 01810), nalidixic acid (2.5mg, Cat. No. 70162) and vancomycin (10mg, Cat. No. 94747) to make the medium selective. Mix well before pouring into sterile petri plates or tubes.
For isolation of the Campylobacter species add the rehydrated contents of one vial of Campylobacter Growth Supplement (Cat. No. C2847) and 5-7% defibrinated sheep blood to 500 ml of medium base. 500 ml of medium base. The Campylobacter Growth Supplement can also be made by mixing 125 mg sodium pyruvate (Cat. No. 15990), 125 mg sodium metabisulfite (Cat. No. 71928 )and 125 mg ferrous sulfate (Cat. No. 44970) in 2 ml of distilled water and filtering the solution through a sterile 0.4 mm filter to sterilize.
