The resulting devastation to the site's output and schedules, as well as to its staff's peace of mind, makes it urgent to avoid any repetition of the experience," says Dennis Champagne, author of the white paper and Director of Lab Services at Microtest Laboratories, a leader in biopharmaceutical and mycoplasma tests and services.
"Whereas the traditional direct cultivation method takes 28 days to provide results, modern real-time PCR mycoplasma tests and analysis in an experienced testing laboratory may be accomplished in an actual testing duration of only 24 hours, plus the time needed for sample collection, shipment, preparation, and handling," he said.

They carry in invasive organisms on themselves -as well as on the equipment and materials they bring into the environment," says Dennis Champagne, author of the white paper and Director of Lab Services at Microtest Laboratories.
With more than 13 years' experience in regulatory microbiology and contract laboratory operations, Champagne leads Microtest's microbiology, contract analytical chemistry, laboratory support, and virology departments.
He holds a B.S. degree in microbiology from Iowa State University, and is a nationally-registered microbiologist.
"Fast action is vital.
To get the cleanroom back up and running as quickly as possible, the extent and location of areas affected must be determined, and the exact organism responsible identified," Champagne said.
The white paper identifies the shortcomings of traditional identification methods, such as only identifying bacteria or yeast only; requiring live, isolated colonies; demanding colonies grown in specific media to match library; delivering subjective results; requiring matches against appropriate library for accurate ID; providing library IDs based on multiple strains/species for each entry; and long turnaround times.
As opposed to traditional methods, DNA sequencing for microbial identification has proven highly accurate and is ideal for testing applications, Champagne explains in the white paper.
