The Colibri™ is an automated in vitro diagnostic specimen preparation system for use with WASPLab® to prepare MALDI-TOF targets for the bioMérieux VITEK® MS or Bruker MALDI Biotyper® CA mass spectrometry systems for qualitative identification and microbial suspension for the bioMérieux VITEK® 2 Antimicrobial Susceptibility Testing (AST) system for qualitative testing of isolated colonies of gram-negative and gram-positive bacterial species grown on solid culture media. The Colibri™ is an automated pre-analytical processor that nicks isolated colonies designated by the operator and uses a pipetting system to prepare MALDI-TOF MS (Matrix-Assisted Laser Desorption/lonization-Time of Flight Mass Spectrometry) target slides for bacterial identification and microbial suspension at known concentration for Antimicrobial Susceptibility Testing and purity assessment. The Collori™ software records the identity of each sample and its position on the target slide and communicates this information electronically to the MALDI-TOF MS analyzers. Bacterial suspensions for AST and purity plates are identified by barcode label. The Colibri™ is intended for use by trained healthcare professionals in clinical laboratories in conjunction with other clinical and laboratory findings, including Gram staining, to aid in the diagnosis of bacterial infections. The Colibri™ has not been validated for use in the identification or processing of yeast species, or mycobacteria.

The Colibrí is an instrument which automates the picking of selected colonies from plated media and prepares MALDI target slides for the bioMérieux VITEK MS or the Bruker MALDI Biotyper CA System that are used in clinical laboratories for identification and differentiation of organisms grown on plated media by Matrix-Assisted Laser Desorption/Tonization Time-of Flight Mass Spectrometry (MALDI-TOF MS). The Colibrí automates the preparation of microbial suspensions at known concentration for bioMérieux VITEK 2 System that is used in clinical laboratories for AST analyses. Moreover, the Colibrí is used for Purity Plates preparation for purity assessments. The Colibrí includes the following components: - . Colibrí instrument and software with on-board pipetting system and nephelometer - Colibrí Primary Tubes ● - . Colibrí Spreader - Colibrí Daily Verification kit. ● Colibri is designed to be used in conjunction with the WASPLab device for culture plate incubation and image analysis. After appropriate plate incubation, the operator selects the colonies from a digital image of culture media plate streaked with microbiological human specimen, available through WebApp software, the WASPLab User Interface. The operator assigns the automatic ID or AST tasks to the isolated colonies to be processed. Then, the operator loads the plates in the Colibri where colonies are automatically picked, spotted on the target slide and overlayed with the matrix or suspended into the dedicated solution for the preparation of the microbial suspension for AST purposes (Secondary Tube). When used in conjunction with the bioMérieux VITEK MS, the Colibrí can prepare the 48-spot target slides by performing the direct spotting of colonies. The calibrator used for quality control is manually applied by the operator at the end of the automated colony spotting. When used in conjunction with the Bruker MALDI Biotyper CA System, the Colibri can prepare either reusable 48-spot or disposable 96-spot targets by performing the Direct Transfer Sample Procedure. The BTS used for quality control is manually applied by the operator at the end of the automated colony spotting. When used in conjunction with the bioMérieux VITEK 2, the Colibrí can prepare the microbial suspension at the proper concentration by direct colony suspension method. The onboard nephelometer allows the preparation of Secondary Tubes (AST suspensions) at the correct concentration and the Colibrí Spreader is used for Purity Plates preparation. The Colibrí software records the identity of each sample and its position on the target slide and communicates this information electronically to the MALDI-TOF MS analyzers. The traceability of prepared Secondary Tube and Purity Plates is maintained by dedicated labels applications. Colibrí requires four different calibrations, one on the nephelometer, three on the cameras. None of these calibration activities require user intervention if not in terms of periodical cleaning of the mechanical component as described in the dedicated section of the User Manual. The Set-up calibration of nephelometer and camera units are performed during the device initial setup. Autocalibration is performed at the end of the initial set-up and periodically during the preventive maintenance to check that all the mechanical references can be found inside the positioning tolerances, that the I/Os are responsive. Run-time calibration is performed during the normal usage to automatically check the proper functioning of the Colibrí. Colibrí requires a daily nephelometer verification to check the proper reading of suspensions at different turbidity values.
