Table 3. Results of biochemical tests on Salmonella Enteritidis (n = 27).

Type of test	Result		Informationc
	Positive (+)a	Negative (-)b
Indole	0	27	The surface of the media is yellow; no pink ring is formed after the Kovac’s reagent was added
MRd	27	0	The methyl red indicator diffuses with the MR-VP media so that the color of the media is red
VPe	0	27	There is no red color on MR-VP media after alpha naphtol, and KOH were added
Lysine	27	0	The LDBf media returns to purple
Citrate	27	0	The development of Salmonella colonies shown with changes in the color of the media from green to blue
