Charismatic Bacteria

Urea/PDA Disks

Hardy’s Rapid Urea/PDA Disks will help you to quickly rule out harmless non-lactose fermentors when screening stool specimens for Salmonella and Shigella.

This test is useful in differentiating Proteus, Providencia, and Morganella species from most other members of the Enterobacteriaceae. HardyDisk™ Urea/PDA Disks are used to determine an organism’s ability to hydrolyze urea to ammonia, and to deaminate phenylalanine to phenylpyruvic acid.

This is a rapid two hour test that is useful in screening out lactose negative stool flora (on MacConkey, HE, XLD, or EMB) that is not pathogenic (Proteus, Providentia, Morganella) from true pathogens (Shigella or Salmonella). This rapid and inexpensive test prevents the waste of expensive Vitek cards and other ID systems.

  • Why is it that when you’re driving and looking for an address, you turn down the volume on the radio?
  • Why is it so hard to remember how to spell ‘mnemonic’?
  • If someone invented instant water, what would they mix it with?
