Plain-English summary
LYFO-DISK Enterococcus faecalis derived from ATCC 51299 is an in vitro diagnostic control product manufactured by Microbiologics Inc. It is used as a reference standard in laboratory testing.
This product is being recalled because specific lots failed quality testing. When tested on the Vitek 2 AST-GP67 card, the High Level Gentamicin Synergy value was out of specification (sensitive). These same lots also failed the disk diffusion method used for product release testing. As a result, these controls may return incorrect susceptible results.
A total of 183 units have been distributed worldwide, including throughout the United States (including Puerto Rico and Guam), Australia, and many other countries.
Laboratories that have used the affected lots should review any susceptibility test results that relied on these controls for validation. The affected lot numbers are 959-94-1, 959-94-4, 959-95-3, 959-96-2, and 959-97-3, with expiration dates ranging from April 30, 2020 to March 31, 2021.
