For selective enrichment, aliquots were transferred to test tubes containing Tetrathionate (Oxoid) and Rappaport Vassiliadis (Oxoid) broths, and the respective tubes incubated at 37[degrees]C for 24h and at 42[degrees]C for 24h.
detection, sample homogenates were enriched using tetrathionate broth and incubated at 35[degrees]C for 24 h before being plated on xylose lysine tergitol-4 agar at 35[degrees]C for 24 h before detection.
Standard bacteriological procedures were performed for bacteria management: samples were transported in 10 ml of Buffered Triptone-Water incubated for 24 h at 37[degrees]C, pre-enriched in Rappaport Vassiliadis Broth and Tetrathionate Broth Base (Difco Laboratories, United States).
After that, 1 ml of the pre enrichment broth was transferred to 10 ml Tetrathionate broth and incubated at 37[degrees]C overnight (18-24 hr).
1 ml of pre-enrichment to 10 ml of Rappaport Vassiliadis (RVS) broth(Oxoid) and 1 ml to 9 ml of tetrathionate of sodium and bright green (MKTTn) broth (Oxoid), followed by incubating of RVS and MKTTn for 24 h at 42[degrees]C and 37[degrees]C respectively.
6 the first anodic peak was pH independent, which is likely to represent oxidation of the electrochemically formed tetrathionate ion [S.
Selective enrichment was performed in tetrathionate (TT) broth and modified Rappaport-Vassiliadis (RV) broth, followed by incubation at 36 [+ or -] 1[degrees]C for 24 h and 42[degrees]C for 24-48 h, respectively.
1 ml of the culture was added to one test tube with 10 ml of tetrathionate broth and to another with selenite, to which were added 2 drops of lugol and 2 drops of green coloring at 0.
No Salmonella species were detected on brilliant green agar (Oxoid Ltd, Hampshire, United Kingdom), even after enrichment in tetrathionate broth.
