Real-World Testing: Putting BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA) to the Test

First Use Experience

My testing ground was the aforementioned rural clinic, where rapid and accurate strep testing is essential for timely patient care. I implemented the plates alongside the clinic’s existing rapid antigen tests to provide a more definitive diagnostic confirmation. Swabs from patients presenting with suspected strep throat were streaked onto the BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA).

The plates were incubated at 35-37°C in a CO2 incubator for 24-48 hours. Reading the plates was straightforward; the selective agents effectively inhibited most non-Group A strep organisms, making identification easier. After the first set of cultures, I noted several instances where the rapid antigen test returned a negative result, but the BD BBL Group A Selective Strep Agar showed clear beta-hemolytic colonies characteristic of Streptococcus pyogenes.

Extended Use & Reliability

After several weeks of continuous use, the BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA) proved remarkably consistent. The rate of false negatives compared to rapid antigen tests dropped significantly, improving diagnostic accuracy. The plates exhibited minimal signs of degradation, even when stored at the higher end of the recommended 2-8°C range.

Maintenance was minimal, primarily involving proper storage and disposal after use according to the clinic’s biohazard protocols. Compared to my previous experience with manually prepared agar plates, the BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA) are a clear winner in terms of convenience and reliability. They consistently outperformed the rapid antigen tests in identifying true positives, instilling confidence in the diagnostic process.

Breaking Down the Features of BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA)

Specifications

The BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA) is designed for the selective isolation of Group A Streptococcus from clinical specimens. Each plate contains a selective medium enriched with 5% sheep blood. The plates measure 100x15mm and are pre-poured and ready for immediate use, reducing preparation time and minimizing contamination risk.

The key ingredients include a basal medium, sheep blood, and selective agents like crystal violet and colistin. These agents inhibit the growth of most Gram-negative bacteria and many Gram-positive bacteria, allowing for the preferential growth of Group A strep. The 5% sheep blood facilitates the visualization of hemolysis patterns, particularly beta-hemolysis, which is characteristic of Streptococcus pyogenes. These specifications are crucial because they directly influence the accuracy and reliability of strep throat diagnoses.

Performance & Functionality

The BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA) excels in its primary function: selectively isolating and identifying Group A Streptococcus.
