We are excited to unveil PERFECTO Duo®, a brand-new and innovative solution designed to transform the detection and enumeration of Clostridium species. This unique technology offers rapid, simultaneous enumeration of Clostridium spp. and Clostridium perfringens — all on a single plate and in just 18 hours.
Scientific Background: Understanding Clostridium
The genus Clostridium comprises a diverse group of Gram-positive, spore-forming, obligate anaerobic bacteria commonly present in soil, water, the gastrointestinal tract of humans and animals, and various environmental reservoirs.
Many Clostridium species are harmless; however, several have significant relevance in food safety, public health, and industrial microbiology due to their ability to form heat-resistant spores and survive harsh processing conditions.
Clostridium perfringens: A Key Indicator Organism
Among the species of concern, Clostridium perfringens is widely monitored as:
· A major cause of foodborne illness
· An indicator of faecal contamination
· A relevant target organism in hygiene and environmental controls
Its rapid growth rate and toxin-producing capabilities make timely detection essential to ensure compliance with microbiological criteria and preventive safety measures.
Given these challenges, laboratories require fast, accurate, and practical methods for both detection and confirmation—needs that PERFECTO Duo® directly addresses.
A Powerful Method for Multiple Sample Types
PERFECTO Duo® brings unmatched efficiency to microbiological testing across a variety of industries, making it ideal for:
· Human food products
· Animal feed
· Environmental samples
Its versatile design ensures reliable, reproducible results regardless of sample type, while optimizing both speed and ease of use.
Easy to Use, Easy to Read
One of the key strengths of the PERFECTO Duo® method is its intuitive workflow and clear visual differentiation. The medium is specially formulated to allow users to distinguish C. perfringens from other Clostridium species at a glance, supporting accurate enumeration and interpretation.
Rapid Confirmation in Just 15 Minutes
To further streamline the process, the method integrates seamlessly with CONFIRM’ C. perfringens – a fast, non-toxic confirmation test. This tool enables direct confirmation of C. perfringens in only 15 minutes, with no purification step required, significantly reducing hands-on time and overall workflow duration.
A Reliable Alternative to ISO Standards
PERFECTO Duo® is officially recognized as an alternative method to:
· NF EN ISO 15213-1 (2023)
· NF EN ISO 15213-2 (2023)
This ensures compliance with current analytical standards while providing laboratories with a more efficient testing solution.
A New Era of Clostridium Detection
With its speed, simplicity, and precision, PERFECTO Duo® represents a major advance in microbiological analysis. Whether your work involves food safety, feed production, or
environmental monitoring, this innovative method delivers the reliability and efficiency required for modern laboratory testing.
