Thermo Scientific™ Colistin Disk

Description

• Confirm Gram-stain reaction of anaerobes and presumptively identify anaerobic, Gram-negative bacilli with Thermo Scientific™ Remel™ Colistin Disk
• In 1971 Sutter and Finegold 1 recommended a method to identify anaerobic, Gram-negative bacilli based on the difference in response to an antibiotic
• Accordingly, organisms can be grouped based on their characteristic inhibitory patterns with erythromycin, rifampin, colistin, penicillin, kanamycin and vancomycin 2,3
• Confirm Gram-stain reactions of anaerobes and presumptively identify anaerobic, Gram-negative bacilli with Colistin Disks
• Ready to use : Colistin-impregnated disk
• Easy to interpret: Sensitive organisms exhibit an inhibitory zone greater than 10 mm around the antibiotic disk while resistant organism exhibit no inhibitory zone i.e., a zone that is less than 10 mm around the disk
• Colistin Disk contains 10 μg colistin
• Disks impregnated with erythromycin, rifampin, colistin, penicillin, kanamycin and vancomycin can be used to identify anaerobic, Gram-negative bacilli based on the zone of inhibition they exhibit
• Colistin and vancomycin confirm the Gram-stain reaction, which is helpful with Clostridia that stain Gram-negative
• Penicillin, rifampin and kanamycin separate Bacteroides and Fusobacterium .
