Liofilchem® Furazolidone FR, Antimicrobial Susceptibility Discs, 50 µg

Liofilchem® Furazolidone FR Antimicrobial Susceptibility Discs are standardized antibiotic-impregnated paper discs used for the in vitro determination of bacterial susceptibility to Furazolidone by the disk diffusion method.

Furazolidone is a nitrofuran antimicrobial agent historically used against a range of Gram-negative and Gram-positive bacteria, particularly in enteric infections. These discs are intended for routine clinical microbiology testing, epidemiological surveillance, research, and teaching applications.

Each disc is manufactured under strict quality-controlled conditions, ensuring accurate antibiotic content, reproducible diffusion characteristics, and reliable zone diameter results.

Intended Use

• In vitro antimicrobial susceptibility testing (AST)
• Determination of bacterial susceptibility or resistance to Furazolidone
• Support of clinical diagnosis, alongside clinical and laboratory findings
• Research and teaching in microbiology laboratories

Principle of the Test

The disk diffusion method involves placing a Furazolidone-impregnated disc onto the surface of an agar plate (typically Mueller–Hinton Agar) previously inoculated with a standardized bacterial suspension.

• Furazolidone diffuses radially into the agar
• Susceptible organisms show inhibition of growth, forming a clear zone
• The diameter of the inhibition zone is measured and interpreted using accepted interpretive criteria, where available
