Brain Heart Infusion Agar is used for the cultivation of a wide variety of fastidious organisms and is not intended for use in the diagnosis of disease or other conditions in humans. A general purpose nutritious agar base. This medium was first used for the isolation of dental pathogens. With the addition of 7% defibrinated blood the medium will support the growth of a wide range of fastidious organisms, the phosphate buffer will help neutralize the acids produced from the utilization of glucose and thus maintain viability. The medium is not recommended for the determination of hemolytic reactions because of the glucose content.

Reagent D eliminates DNA from dead cells to prevent false-positive PCR results in food safety testing. This light-sensitive reagent penetrates dead cell membranes and binds to DNA upon light exposure, blocking PCR amplification. Validated for testing: Enterobacteriaceae Cronobacter Salmonella Legionella Vibrio in various food matrices including instant milk formula and dairy products. Compatible with Hygiena's DNA isolation kits, Reagent D ensures accurate detection of viable microorganisms in food safety and environmental monitoring applications.

DNase Agar is used for the differentiation of microorganisms on the basis of deoxyribonuclease activity and is not intended for use in the diagnosis of disease or other conditions in humans. In 1956, Weckman and Catlin showed a correlation between increased DNase activity of Staphylococcus aureus and positive coagulase activity. Their research suggested DNase activity could be used to identify potentially pathogenic staphylococci. DiSalvo confirmed their results by obtaining excellent correlation between coagulase and DNase activity of staphylococci isolated from clinical specimens. Jeffries, Holtman, and Guse incorporated DNA in agar to study DNase production by bacteria and fungi. Polymerized DNA precipitates in the presence of 1N HCl, creating an opaque medium. Organisms that degrade DNA produce a clear zone around an inoculum streak. Fusillo and Weiss studied calcium requirements of staphylococci for DNase production, and concluded additional calcium was unnecessary when a complete nutritive medium was used.
