Culture-Based Bulk, Swab or Teftex Wipe Samples

This test uses conventional culture and microscopical techniques to provide a species-level identification of a purified fungal culture. While this approach is successful in many cases in assigning robust species identifications, many groups of fungi contain species that cannot be differentiated by this approach and require additional analytical methods such as DNA sequencing. Occasionally, a […]

This test measures total culturable molds and yeasts contained in a sample of pharmaceutical product, personal care product, medical device, or other similar material by culturing a measured amount of the sample on Sabouraud Dextrose Agar and incubating at 20-25°C for a minimum of 5 days prior to analysis. At the end of the incubation […]

This test measures total culturable bacteria contained in a sample of pharmaceutical product, personal care product, medical device, or other similar material by culturing a measured amount of the sample on Tryptic Soy Agar and incubating at 30-35°C for a minimum of 3 days prior to analysis. At the end of the incubation period, bacterial […]

Background The Gram negative bacterium Pseudomonas aeruginosa is commonly found in soil, water, and other natural environments. It is an opportunistic pathogen that can cause infections in humans, particularly in individuals with weakened immune systems, such as those with cystic fibrosis or hospitalized patients. P. aeruginosa is known for its ability to form biofilms, which […]

Coliform bacteria are common environmental bacteria, typically associated with the mammalian digestive tract. Although not generally pathogenic themselves, coliforms are a well-known marker of fecal contamination, and their presence is interpreted to suggest that potentially pathogenic bacteria may be present. This test detects both E. coli and coliform bacteria in bulk water samples or from […]
