Thermo Fisher Scientific and SpeeDx have signed an agreement to develop and submit for FDA clearance the ResistancePlus MG Test for detecting *M. genitalium*, a rapidly growing sexually transmitted infection that has developed significant resistance to first-line antibiotic treatments. Under the terms of the agreement, SpeeDx will submit the test to FDA upon successful validation for use with Applied Biosystems’ 7500 Fast Dx Real-Time PCR System.

  
The test is designed to identify both *M. genitalium* and mutations in the 23S rRNA gene of the bacteria that have been shown to build resistance to azithromycin. The disease can cause symptoms such as urethritis, cervicitis, endometritis and pelvic inflammatory disease, the companies say.
