Advancing Enteric Pathogen Identification with TSI Agar

Accurate differentiation of Gram-negative enteric bacteria remains a cornerstone of modern microbiology and food safety testing. Triple Sugar Iron Agar (TSI Agar) continues to be one of the most widely used differential media for identifying enteric bacilli based on carbohydrate fermentation patterns and hydrogen sulfide (H₂S) production.

BABIO’s Triple Sugar Iron Agar is formulated to support reliable identification of clinically and industrially significant organisms, including Salmonella spp., Escherichia coli, Shigella, and other Enterobacteriaceae. By combining glucose, lactose, and sucrose fermentation with iron salt indicators, TSI Agar enables laboratories to rapidly interpret acid/gas production and sulfur reduction in a single test medium.

Produced in powder and granule forms, BABIO TSI Agar offers excellent stability, long shelf life, and consistent performance across routine microbiological workflows. It is widely applied in food factories, pharmaceutical manufacturing, public health laboratories, and research institutions, where standardized pathogen screening and quality control are essential.

As a well-recognized Chinese manufacturer, BABIO (Babio Biotechnology) supplies a comprehensive portfolio of microbiological culture media—covering more than 2,000 product types—to global markets. Manufactured under ISO 9001–certified quality systems, BABIO’s TSI Agar meets the expectations of laboratories across Europe and North America for accuracy, reproducibility, and regulatory compliance.
