The tip of the wire should be seen in the citrate compartment. Indicate each positive test interpretatioh by circling the number appearing below the appropriate compartment on the Results Pad Figure 6. To make this website work, we log user data and share it with processors.

Any degree of yellow should be interpreted as Gas production wax not lifted wax lifted a positive reaction; orange should be considered negative. Nahaisi Abstract This study was conducted to investigate the More information. If the database without VP is chosen, it may be necessary to perform the VP reaction as a supplemental test for selected organisms. Lighter shades gkide the same basic color should also be considered positive.


Media, incubation, and aseptic technique Objectives 1. This test detects those organisms which are capable of utilizing citrate, in the form of its sodium salt, as the sole source of carbon. Information on the appearance of positive and negative reactions is provided in Table 1.


The hydrogen sulfide yuide with the iron salts also present in the medium to form a black precipitate of ferric sulfide usually along the line of inoculation. Add circled numbers in the bracketed section and enter the sum in the space provided below the arrow Figure 6. It may be decided by the user if the databases with or without VP are used.
