Abstract: | A 1.3 kb Brucella-specific DNA fragment produced through the use of arbitrarily primed polymerase chain reaction (AP-PCR) was tested for its specificity by DNA–DNA hybridization to Brucella and non-Brucella bacteria. The digoxigenin (DIG)-labelled 1.3 kb DNA fragment hybridized with Brucella abortus and Brucella melitensis but did not hybridize with other non-Brucella bacteria tested. The sensitivity of the reaction was determined; as little as 150 fg DNA or 30 Brucella cells could be detected. The specificity and sensitivity of the 1.3 kb DNA fragment combined with the simplicity and speed of the technique suggest the potential of this fragment as a DNA probe for the quick and reliable detection of Brucella organisms. |
