Abstract
The present invention provides compositions, methods and kits for bacteria identification and anti-microbial susceptibility testing for the treatment of, for example, acute and chronic infections including infectious disease. The present invention is particularly useful in the identification of bacteria causing mastitis, and to antibiotic susceptibility testing to facilitate in the identification of an appropriate treatment for mastitis.
Claims11
A method for performing an antimicrobial susceptibility test on a biological sample obtained from a human or non-human animal, wherein the human or non-human animal may be infected by, or at risk of infection by, one or more infection causing bacteria, the method comprising,
- (i) providing a reaction mix comprising a biological sample obtained from a human or non-human animal and susceptibility media comprising growth media, an antimicrobial agent, a colour based pH indicator and a stabilizing agent comprising a milk derived protein or milk derived protein extract;
- and
- (ii) determining the susceptibility of the one or more bacteria in the sample to the antimicrobial agent by observing a colour change when the sample is mixed with the susceptibility media,
- wherein, the pH indicator is present in the reaction mix in an amount greater than or equal to 0.0035% and sufficient to inhibit growth of the one or more infection causing bacteria if not for the presence of the stabilizing agent.
