Abstract
The detection of residues of antibacterials such as antibiotics and sulpha compounds in liquids such as milk, water, meat juice, serum or urine is disclosed. A test unit comprises an agar medium inoculated with a suitable test organism and two or more redox indicators.
Claims23
A method for detecting antibacterials in a test sample which comprises
- a) bringing a test organism and at least two redox indicators into an agar medium,
- b) allowing the test sample to come into contact with the agar medium such that antibacterials in the test sample inhibit the test organism in the agar medium,
- and c) observing the contacted test sample for the presence or absence of a color change in the visible part of the spectrum which is indicative of the presence or absence of antibacterials.
The method according to any one of the preceding claims wherein the sensitivity of the test organism to antibacterial compounds is adjustable.
A composition for detecting antibacterials which comprises an agar medium comprising a test organism, optionally a separate nutrient source and two or more redox indicators which each can be present in the agar medium or the separate nutrient source.
