Ordering Guidance

If susceptibility testing is needed; order MMLSA / Antimicrobial Susceptibility, Anaerobic Bacteria, MIC also. If susceptibilities are not appropriate, MMLSA will be canceled at report time.

Shipping Instructions

1. See Infectious Specimen Shipping Guidelines in Special Instructions for shipping information.

2. Place specimen in a large infectious container (T146) and label as an etiologic agent/infectious substance, if appropriate.

Necessary Information

1. Specimen source is required.

2. Isolate description is required: Gram stain reaction, morphology, tests performed.

Method Description

Appropriately transported organisms are inoculated onto blood agar plates and into thioglycollate broth tubes. After 48 hours of incubation at 35° C in an anaerobic atmosphere, colonies are identified using one or a combination of the following techniques: Gram stain, use of various differential media, aero tolerance testing, conventional biochemical tests, MALDI-TOF mass spectrometry, or 16S ribosomal RNA gene sequencing.(Koneman EW: The anaerobic bacteria. In Color Atlas and Textbook of Diagnostic Microbiology, Sixth edition. Philadelphia, Lippincott, Williams and Wilke, 2006, pp 877-944)

Report Available

8 to 14 days

Reject Due To

Method Name

Dependent on organism submitted, 1 or more of the following methods will be used: media, aero tolerance testing, conventional biochemical tests (MALDI-TOF) mass spectrometry or 16S RNA gene sequencing
