BD 221270 - BBL MacConkey II Agar Plate 100mm Culture Medium for Gram-Negative Bacteria Isolation, 100/BX
The BD 221270 BBL MacConkey II Agar Culture Plate is a high-quality, ready-to-use microbiological medium specifically formulated for the selective isolation and differentiation of gram-negative enteric bacteria. Each 100mm sterile petri dish is pre-filled with MacConkey II Agar, a refined version of the classic MacConkey formula enhanced for improved colony differentiation and consistent performance.
This culture medium is lactose-based and incorporates bile salts and crystal violet to inhibit gram-positive organisms, making it ideal for detecting coliforms and enteric pathogens in clinical, pharmaceutical, food, and water testing applications. The BD BBL plates are designed to deliver high performance in both manual and automated incubation systems used in modern laboratories.
Key Benefits:
Selective Isolation of Gram-Negative Bacteria:Inhibits gram-positive flora, allowing for clear, targeted recovery of organisms such asE. coli,Klebsiella,Salmonella, andEnterobacter.
Color Differentiation with Lactose Fermentation:Differentiates lactose fermenters (pink/red colonies) from non-fermenters (colorless colonies), simplifying preliminary identification.
Ready-to-Use and Sterile:Eliminates time-consuming preparation and sterilization, saving laboratory resources and improving workflow efficiency.
Consistent Lot-to-Lot Quality:Manufactured under stringent BD quality controls, ensuring reproducibility across multiple tests and applications.
Compatible with Standard Incubators:Designed for 3537C aerobic incubation protocols in clinical, research, and industrial labs.
Compatibility and Applications:
BD 221270 MacConkey II Agar plates are widely used in:
Clinical microbiology labs for identifying urinary tract and gastrointestinal infections
Pharmaceutical and biotech quality control labs
Food safety testing for pathogens in raw and processed food samples
Environmental monitoring of water sources for fecal contamination
Compatible with:
Manual streaking and colony isolation methods
Automated plate streaking and imaging systems
Standard laboratory incubators and storage equipment
Usage Guidelines:
Store plates in a refrigerator at 28C. Allow to come to room temperature before inoculation.
Using sterile technique, streak the specimen onto the agar surface.
Incubate aerobically at 3537C for 1824 hours or per specific laboratory protocols.
Observe colony morphology and color to preliminarily identify lactose-fermenting versus non-fermenting organisms.
Dispose of used plates in accordance with local biohazard waste regulations.
Always refer to your laboratorys standard operating procedures or BDs product insert for detailed instructions.

Typical scenarios include detection of enteric pathogens in stool samples, screening urine specimens forE. coli, or verifying the microbiological quality of pharmaceutical products.
Best Practices for Use and Maintenance:
Avoid freezing or exposing plates to direct sunlight or excessive moisture.
Do not use plates past the expiration date or if contamination or desiccation is visible.
Label and track batch numbers for quality control documentation.
Use proper aseptic technique to avoid false positives or cross-contamination.
Regularly validate media performance with known control strains such asE. coliATCC 25922 andSalmonella entericaATCC 14028.
Following these practices supports accurate microbial identification and reduces the likelihood of diagnostic errors.
