Let’s Dive into BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA)
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 a pre-prepared culture medium designed for the isolation and identification of Group A Streptococcus bacteria. Manufactured by BD Diagnostics, these stacker plates offer a convenient and reliable solution for clinical and research laboratories focused on microbiology. The inclusion of 5% Sheep Blood enhances the differentiation of hemolytic patterns, a crucial step in identifying Streptococcus pyogenes.
My journey to this product stemmed from a need for consistent and reliable strep testing in a remote field clinic setting. Transporting and preparing agar plates in less-than-ideal conditions often led to contamination and unreliable results. The pre-prepared, stackable format promised to address these challenges head-on.
Upon unboxing, I was immediately impressed by the professional packaging and the uniformity of the plates. The agar surface appeared smooth and consistent, free from any visible imperfections or contamination. The stackable design felt secure, promising minimal risk of spillage or damage during transportation.
Compared to preparing our own agar plates, or even using other brands’ pre-poured plates, the BD Diagnostics product stood out due to its reputation for quality control and consistency. I had experienced inconsistencies in the past with self-poured plates, and other brands’ pre-poured products didn’t always deliver the same level of confidence. The BD BBL name carries weight in the medical field for a reason.
Initially, I was cautiously optimistic. The promise of reduced prep time and enhanced reliability was exciting, but I also knew that the proof would be in the pudding. I was eager to put these plates to the test in the field and see if they lived up to the hype.
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
The BD BBL Prepared Media Stacker PlatesA7 Agar to Pseudosel Agar, BD Diagnostics 221780 Group A Selective Strep Agar, With 5% Sheep Blood (ssA) were tested in a mobile medical clinic operating in a humid, subtropical environment. Swab samples were collected from patients presenting with suspected streptococcal infections. The plates were inoculated immediately and incubated at a controlled temperature in a portable incubator.
Despite the high humidity, the agar surface remained consistent and free from excessive condensation. The ssA formulation effectively inhibited the growth of many non-streptococcal organisms, aiding in clear and accurate identification of Group A strep colonies based on their characteristic hemolytic patterns around colonies. The ease of use was a significant advantage, drastically reducing prep time in a busy clinical environment.
There were no immediate issues after the initial use. The results appeared consistent with those we would expect from our standard lab setting, a pleasant surprise given that we were operating in less-than-ideal conditions.
Extended Use & Reliability
After several weeks of consistent 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) continued to perform reliably. We observed no significant degradation in the agar quality or consistency across multiple batches. The shelf life, when stored properly, was accurately reflected in the product performance.
The plates exhibited no signs of premature drying or cracking, even with repeated handling during daily testing. Maintaining the BD BBL plates was minimal, consisting solely of proper storage at the recommended temperature (2 to 8°C / 36 to 46°F). This is a massive time saver in a field lab setting.
Compared to previous experiences with other pre-poured agar plates, the BD Diagnostics product consistently delivered more accurate and reliable results. This reduced the need for repeat testing and minimized the risk of false negatives, greatly improving patient outcomes in the field.
