Automatic Microbial Identification System (VITEK) ¾

rapid and fully automated identification and susceptibility system

¾

automatically scanned by the photometric sensors under controlled chamber once every hour

¾

detecting the change in color and turbidity for identification of groups of bacteria

Automatic Microbial Identification System (VITEK) Testing: ¾ Gram-negative bacteria (GNI+) ¾ Gram-positive bacteria (GPI) ¾ Gram-negative non-fermenting bacteria (NFC) ¾ Anaerobic bacteria (ANI) ¾ Yeast (YBC) ¾ Bacillus species (BAC) ¾ Neisseria and Haemophilus species (NHI) ¾ Bioburden (BIO) ¾ Susceptibility tests of Gram-negative bacteria (GNS) ¾ Susceptibility tests of Gram-positive bacteria (GPS)

Accredited Fish Farm Scheme Primary Drug Residues Screening: Premi ® Test ¾

Bacillus stearothermophilus – very sensitive to many antibiotics & sulphonamide residues

¾

Meat fluid is added to Premi®Test and incubated at 64°C. If antimicrobials residues are present in sufficient amount, no growth of Bacillus stearothermophilus. This will be visible by no color change.

¾

Advantage: screen a broad spectrum of antibiotic at very short time.

Accredited Fish Farm Scheme Drug residues detected by Premi ® Test : β-lactam ¾ Amoxicillin ¾ Ampicillin ¾ Penicillin Tetracyclines ¾ Chlortetracycline ¾ Oxytetracycline ¾ Tetracycline ¾ doxycycline Macrolides ¾ Tylosin ¾ Lincomycin ¾ Spiramycin ¾ Erythromycin

Sulphonamides ¾ Sulfapyridine ¾ Sulfamethoxypyridine ¾ Sulfathiazole ¾ Sulfadiazine ¾ Sulfamerazine ¾ Sulfaquinaxaline ¾ Sulfamethoxy-pyridine ¾ Sulfaquinaxaline
