Intended Use

The Sensititre MIC and Breakpoint Susceptibility system is an in vitro diagnostic product for clinical susceptibility testing of non-fastidious Gram negative isolates, comprising of Enterobacteriaceae, Pseudomonas aeruginosa, and other non-Enterobacteriaceae and of non-fastidious Gram positive isolates, comprising of Staphylococcus spp., Enterococcus spp., and Beta haemolytic Streptococci other than S. pneumoniae.

Device Story

Sensititre 18-24 hour MIC system; multi-well plastic micro-titer plates containing dried, stabilized antimicrobials; micro-version of broth dilution method. Clinical lab use; requires Sensititre AIM autoinoculator for sample preparation; plates incubated 18-24 hours. Growth detection via VIZION digital viewing device (video camera/touch screen) or OptiRead automated reader (fluorescence technology). OptiRead detects bacterial growth by monitoring surface enzyme activity; fluorogenic substrate cleavage releases fluorescence proportional to growth. Output: Minimum Inhibitory Concentration (MIC) and interpretive criteria (S, I, R). Healthcare providers use MIC results to guide antimicrobial therapy decisions for non-fastidious Gram-positive infections.

Clinical Evidence

Bench testing only. Performance was evaluated by comparing the Sensititre system's MIC results for Delafloxacin against a reference broth microdilution method. Testing included clinical isolates of Staphylococcus aureus, Staphylococcus haemolyticus, Staphylococcus lugdunensis, and Enterococcus faecalis. Results demonstrated essential agreement and categorical agreement within acceptable FDA criteria for antimicrobial susceptibility testing devices.

Technological Characteristics

Microbroth dilution susceptibility testing system. Consists of multi-well plates containing dehydrated antimicrobial agent (Delafloxacin) in 0.0005-8 ug/ml range. Operates via visual or automated growth detection after 18-24 hour incubation. Designed for non-fastidious Gram-positive organisms. Standardized laboratory equipment.

Indications for Use

Indicated for in vitro clinical susceptibility testing of non-fastidious Gram-positive organisms, specifically Staphylococcus aureus (MRSA/MSSA), Staphylococcus haemolyticus, Staphylococcus lugdunensis, and Enterococcus faecalis, using Delafloxacin in the 0.0005-8 ug/ml range.

Regulatory Classification

Identification

An antimicrobial susceptibility test powder is a device that consists of an antimicrobial drug powder packaged in vials in specified amounts and intended for use in clinical laboratories for determining in vitro susceptibility of bacterial pathogens to these therapeutic agents. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.
