Test ID: IDENT Organism Referred for Identification, Aerobic Bacteria

Infectious

Reporting Name

Organism Refer for ID, Aerobic Bact

Useful For

Identification of pure isolates of aerobic bacteria

 

Differentiation of members of the Staphylococcus aureus complex (S aureus, S argenteus, S schweitzeri)

Clinical Information

Organisms are referred to confirm identification or when the identity is unknown. This may provide helpful information regarding the significance of the organism, its role in the disease process, and its possible origin.

 

Techniques employed may include conventional biochemical analysis, commercial identification strips or panels, matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry or sequencing nucleic acid of the 16S ribosomal RNA (rRNA) gene.

Interpretation

Genus and species are reported on aerobic bacterial isolates, whenever possible.

 

Bacillus species will be reported out as "Large spore-forming aerobic gram-positive Bacillus, not Bacillus cereus or Bacillus anthracis," unless species identification is specifically requested on the request form.

Report Available

5 to 10 days

Day(s) Performed

Monday through Sunday

Method Name

Dependent on organism submitted, 1 or more of the following methods will be used: conventional biochemical testing, commercial identification strips or panels, Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) mass spectrometry, and 16S RNA gene sequencing.

Ordering Guidance


If susceptibility testing is needed; also order ZMMLS Antimicrobial Susceptibility, Aerobic Bacteria, MIC. If susceptibilities are not appropriate and will not be performed, ZMMLS will be canceled at report time.

Testing Algorithm

When this test is ordered, the reflex tests may be performed and charged. All aerobically growing bacteria submitted will be identified and billed as appropriate.

Note: Mayo Clinic Laboratories recommends referring suspect select agent isolates (eg, Bacillus anthracis, Brucella species, Burkholderia mallei, Burkholderia pseudomallei, Francisella tularensis, or Yersinia pestis) to your state health department or the CDC for identification confirmation or exclusion.
