Mueller Hinton Agar Plate with 5% Sheep Blood is a ready-to-use, pre-poured culture medium specifically designed for antimicrobial susceptibility testing (AST) of fastidious organisms, particularly Streptococcus species, Haemophilus species, and Neisseria species. The addition of 5% defibrinated sheep blood enriches the medium to support the growth of organisms that do not grow adequately on plain Mueller Hinton Agar, enabling accurate disc diffusion testing as per the Kirby-Bauer method.
