This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.Staphylococcus aureus (S. aureus) subsp. aureus, transposon mutant NE1345 was derived from S. aureus subsp. aureus, strain JE2. Mutagenesis occurred through the use of the mariner-based transposon bursa aurealis resulting in an erythromycin-resistant deletion strain of JE2. S. aureus subsp. aureus, transposon mutant NE1345 was created by disruption of
menD, which encodes for a 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylic
acid synthase/2-oxoglutarate decarboxylase that catalyzes the first dedicated step of menaquinone (vitamin K
2)
biosynthesis. Loss or mutation of this enzyme increases resistance to aminoglycosides. S. aureus subsp. aureus, strain JE2 is a plasmid-cured derivative of strain LAC that was isolated in 2002 from a skin and soft tissue infection of an inmate in the Los Angeles County Jail in California, USA. Strain JE2 is a methicillin-resistant S. aureus (MRSA) strain and is a USA300 isolate. USA300 isolates have the same MLST profile (ST 8), SCCmec (subtype IV), agr group (I) and spa motif (MBQBLO) and typically carry the Panton-Valentine leukocidin (PVL) toxin genes and the arginine catabolic mobile element (ACME). USA300 is the most common cause of community-associated MRSA infection and an increasing cause of hospital-acquired infections.Each vial contains approximately 0.5 mL of bacterial culture in Tryptic Soy broth containing 5 ?g/mL erythromycin supplemented with 10% glycerol.The Nebraska Transposon Mutant Library (NTML) was constructed in the laboratories of Dr. Ken Bayles and Dr. Paul Fey at the University of Nebraska Medical Center.

NTML website.
