Middlebrook Agar – Composition, Principle, Preparation, Results, Uses
Over the years, many media have been developed for mycobacteria cultivation. Early ones included egg-based formulations such as Lowenstein-Jensen Medium or Petragnani Medium. Later, Dubos, Middlebrook and Middlebrook created a variety of formulations that contained oleic and albumin as key components. These ingredients protect Mycobacterium against toxic agents and allow for the growth and development of tubercle bacteriailli. Cohn and Middlebrook improved the formulations of oleic acids-albumin agar to achieve a faster and more luxurious growth of Mycobacterium strains.
