Dalynn - Model DD10-25 - Microbiology Disks Brochure

Our 0129 Disks are used for the differentiation of vibrios from other gram-negative bacteria. Shewan and Hodgkiss recognized the sensitivity of vibrios to the vibrio-static agent 0129 (2,4-diamino-6.7-di-isopropyl-pteridine phosphate) in 1954. 0129 was found to be useful in the differentiation of vibrios from other gram-negative bacteria especially aeromonads. which are characteristically resistant to 0129. Among the genera, different species of vibrios show different sensitivities to 0129; this can be used as a diagnostic feature as antimicrobial disks of different concentrations can be used to determine their degree of sensitivity.
