The number of colonies present on the plates are then counted and the results are calculated. It is estimated that more than 131 million Americans 66% of all adults in the country use prescription drugs, making the pharmaceutical industry one of the most consequential businesses in the nation and around the globe.1 According to industry statistics, the pharmaceutical drug market has experienced significant growth over the past two decades; pharma revenues in the U.S. topped $490 billion in 2019, while the global pharmaceutical market was valued at $1.25 trillion (USD).2 With industry titans, like Johnson & Johnson, Pfizer, Lilly, Abbott Laboratories and Roche, setting the pace, the global pharmaceutical market fueled by projected sales growth in Brazil, Russia, India, China, and other emerging marketplaces is expected to reach $1.5 trillion (USD) by 2023.2The ongoing and sustained growth of the U.S. pharmaceutical drug industry is being driven by a number of factors, including 3,4. You can find brief descriptions for each of the bioburden testing methods mentioned below. At the end of the incubation period, the plates are removed and the colony forming units are counted. For samples with a high bioburden, the dilution which represents 30 300 colonies are counted. FOCUS plates all dilutions in duplicate, so the average of the two plates is calculated, and the count is multiplied by the dilution factor. In other words, if an average of 72 colonies was counted on duplicate 10-2 plates, a count of 7200 cfu/gm of product would be reported for that plate count. All this for $30! USP 61 covers sample preparation, controls, and tests to quantify mesophilic bacteria and fungi. Many of the changes are designed to harmonize with the European Pharmacopeia methods.
