Intended Use

VITEK® 2 Streptococcus Tigecycline is designed for antimicrobial susceptibility testing of Streptococcus species and is intended for use with the VITEK® 2 and VITEK® 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. VITEK® 2 Streptococcus Tigecycline is a qualitative test. Tigecycline has been shown to be active against most strains of the microorganisms listed below, according to the FDA label for this antimicrobial.

(includes S. anginosus, S. intermedius, and S. constellatus) Streptococcus agalactiae Streptococcus pyogenes

Device Story

VITEK 2 AST-ST Tigecycline is an in vitro diagnostic test for determining antimicrobial susceptibility of Streptococcus species. The device uses miniaturized cards containing antimicrobial concentrations equivalent to standard broth microdilution methods. Clinical isolates are diluted in saline, used to rehydrate the card, and processed by VITEK 2 or VITEK 2 Compact systems. The system automatically fills, seals, and incubates the card while monitoring bacterial growth via optical sensors over 18 hours. The system generates a report with MIC values and interpretive categories. Used in clinical laboratories by technicians to guide antibiotic therapy decisions by identifying susceptible bacterial strains, potentially improving patient outcomes through targeted treatment.

Clinical Evidence

Performance evaluated using fresh and stock clinical isolates and challenge strains. Compared against CLSI broth microdilution reference method (20-24 hrs). Demonstrated 99.8% overall category agreement. Reproducibility and quality control results were acceptable.

Technological Characteristics

Test card with 64 micro-wells containing culture media and Tigecycline (0.125, 0.25, 0.5 µg/mL). Sensing principle: optical light transmittance/attenuation to measure bacterial growth. Energy source: electrical (automated system). Connectivity: VITEK 2/VITEK 2 Compact systems. Software: Growth Pattern Analysis (GPA) algorithm.

Indications for Use

Indicated for antimicrobial susceptibility testing of Streptococcus species (S. pneumoniae, S. anginosus group, S. agalactiae, S. pyogenes) using isolated colonies. For professional laboratory use.

Regulatory Classification

Identification

A fully automated short-term incubation cycle antimicrobial susceptibility system is a device that incorporates concentrations of antimicrobial agents into a system for the purpose of determining in vitro susceptibility of bacterial pathogens isolated from clinical specimens. Test results obtained from short-term (less than 16 hours) incubation are used to determine the antimicrobial agent of choice to treat bacterial diseases.

Special Controls

*Classification.* Class II (special controls). The special control for this device is FDA's guidance document entitled “Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA.”

VITEK® 2 Streptococcus Tigecycline is designed for antimicrobial susceptibility testing of Streptococcus species and is intended for use with the VITEK® 2 and VITEK® 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. VITEK® 2 Streptococcus Tigecycline is a qualitative test. Tigecycline has been shown to be active against most strains of the microorganisms listed below, according to the FDA label for this antimicrobial.

Active in vitro and in clinical infections Streptococcus pneumoniae (penicillin-susceptible isolates) Streptococcus anginosus grp. (includes S. anginosus, S. intermedius, and S. constellatus) Streptococcus agalactiae Streptococcus pyogenes

The antimicrobial presented in VITEK® 2 AST-ST Cards is in concentrations equivalent by efficacy to standard method concentrations in mcg/ml. The VITEK® 2 AST Cards are essentially miniaturized versions of the doubling dilution technique for determining the minimum inhibitory concentration (MIC) microdilution methodology.

The isolate to be tested is diluted to a standardized concentration in 0.45 - 0.50% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK® 2 automatically fills, seals and places the card into the incubator/reader. The VITEK® 2 Compact has a manual filling and sealing operation. The VITEK® 2 monitors the growth of each well in the card over a defined period of time (up to 18 hours). At the completion of the incubation cycle, a report is generated that contains the MIC value along with the interpretive category result for each antimicrobial contained on the card.

VITEK® 2 AST-ST Tigecvoline demonstrated substantially equivalent performance when compared with the CLSI broth microdilution reference method, as defined in the FDA Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA. Issued August 28, 2009.

The Premarket Notification (510[k]) presents data in support of VITEK® 2 AST-ST Tigecycline. An external evaluation was conducted with fresh and stock clinical isolates, as well as a set of challenge strains. The external evaluations were designed to confirm the acceptability of VITEK® 2 AST-ST Tigecycline by comparing its performance with the CLSI broth microdilution reference method incubated at 20 - 24 hrs. The data is representative of performance on both the VITEK® 2 and VITEK® 2 Compact instrument platforms. VITEK 2 AST-ST Tigecycline demonstrated acceptable performance of 99.8% overall category agreement with the reference method. Reproducibility and Quality Control demonstrated acceptable results.
