16S rRNA and Mip Gene Sequencing<<Return to Search Results
*Accredited by the Standards Council of Canada to Laboratory no. 594 - CAN-P-4E (ISO/IEC 17025)
16S rRNA gene PCR*, sequencing, and phylogenetic analysis. Mip gene sequencing and phylogenetic analysis is used complementarily with 16S gene sequencing and is dependent on the 16S gene sequencing results.
Pure cultures of isolate implicated in clinical illness or environmental isolates.
Slants or plates of any suitable media and swabs in transport media are all acceptable.
Store and ship samples at room temperature.
Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.

Clinical illness with symptoms suggestive of bacterial infection.
Completed Special Bacteriology requisition form detailing all patient information and relevant clinical information. If possible, attach lab results that have already been done at local or provincial laboratories.
All patient and strain history must be included. Please note that multiple samples isolated from the same source and patient, and identified as the same organism by the sender, will need an explanation in order for testing to be done on all the samples. Acceptance and/or rejection of the additional samples is at the discretion of the Special Bacteriology lab. Contact lab for further information. Please refer to the Guide to Services for test services offered by the NML.
16S and mip gene (if applicable) sequencing results are compared against publically-available databases (GenBank) and known type strains.
15 calendar days for the 16S/secondary gene target final report. Report may be delayed in cases where staff or resources are limited, or for poor or slow growing organisms. In cases where further testing is required, the final report may be delayed and status of request will be forwarded in a preliminary report. Final report is sent once all testing is complete.
