Description:
Tryptic Soy Agar (TSA) is a nutrient-rich, general-purpose medium designed to support the growth of a wide variety of microorganisms. The inclusion of amphotericin B at 4 µg/mL transforms TSA into a selective medium, effectively suppressing fungal and yeast contamination while permitting bacterial growth. Amphotericin B, a polyene antifungal, binds to ergosterol in fungal cell membranes, disrupting their integrity and preventing overgrowth in mixed samples.
TSA’s balanced formulation-enriched with tryptone, soy peptone, and glucose-provides essential nutrients for robust bacterial proliferation, making it ideal for isolating and cultivating both fastidious and non-fastidious species. The medium’s clarity and stability ensure reliable results in diverse applications, from clinical diagnostics to environmental testing.
Applications:
- Selective isolation of bacteria from samples prone to fungal contamination (e.g., food, soil, clinical specimens).
- Routine cultivation of Salmonella, Listeria, Neisseria, Brucella, and other bacteria in clinical, industrial, or research settings.
- Environmental and food safety testing to monitor microbial quality while suppressing fungal interference.
- Teaching and research in microbiology, particularly for studying bacterial-fungal interactions or antibiotic susceptibility.
Key Benefits
- Antifungal Selectivity: Amphotericin B inhibits fungi/yeasts without affecting bacterial morphology or viability at 4 µg/mL.
- Versatile Nutrition: TSA supports diverse bacteria, including fastidious species, due to its rich peptone and carbohydrate content.
- Stability and Clarity: Light yellow, transparent agar facilitates easy colony observation and enumeration.
- Standardized Use: Complies with protocols for selective media in clinical and industrial microbiology (e.g., replacing cycloheximide in Campylobacter isolation).
Amphotericin B (4 µg/mL) Tryptic Soy Agar Plates are essential for laboratories requiring reliable bacterial isolation in the presence of fungal contaminants. Their combination of broad nutritional support and targeted antifungal action ensures accurate, reproducible results across microbiology workflows.
