STEC PCR 171 5. Washing buffer: buffer 1 with 0.3% Tween ® 20 (Sigma). 6. Blocking stock solution (10X): 10% solution of blocking reagent (Roche Diagnostics) in buffer 1. 7. Buffer 2 blocking solution: 1:10 dilution of blocking stock solution in buffer 1 (final concentration 1%). 8. Buffer 3 (detection buffer): 0.1 M Tris (15.76 g/L), 0.1 M NaCl (5.85 g/L). 9. TE buffer: 100 mM Tris (12.1 g/L), 1 mM EDTA-Na 2 (0.377 g/L). 10. Anti-digoxigenin-AP-conjugate: dilute reagent (Roche Diagnostics) 1:5,000 in buffer 2. (Centrifuge vessel containing the stock solution at 13,000g for 15 min to sediment agglomerates. These could react later and give false positive results on the membrane disc. The diluted AP-conjugate is only stable for 12 h at 4°C.) 11. Color substrate solution: pipet 45 µL of 4-nitroblue tetrazolium chloride (NBT) solution as supplied ready to use from Roche Diagnostics (75 mg/mL in 70% dimethyl formamide), and 35 µL of 5-bromo-4-chloro-3-indolyl-phosphate (BCIP or X-phosphate) from the same source (50 mg/mL in dimethylformamide) into a plastic tube. Make up to 10 mL with buffer 3. 12. Phosphate-buffered saline (PBS) pH 7.5: 8.5 g NaCl, 1.14 g disodium hydrogen phosphate (Na 2HPO 4 × 12 H 20), 0.5 g potassium dihydrogen phosphate (KH 2 PO 4), make up to 1000 mL with distilled water. (Dissolve all salts in approx 900 mL of distilled water and adjust to pH 7.5 with 2 N NaOH. Store at 4°C and use the solution for no longer than 4 wk. 2.4. Characterization of Isolates Reagents for characterization of STEC/EHEC isolates (stx subtyping, detection of virulence factors, eae subtyping ) are given in Tables 1–4. 3. Methods The general course of operation is given in Fig. 2. 3.1. Bacterial Enrichment for Examination of Different Sample Matrixes for STEC / EHEC 3.1.1. Foods 1. Mix 25 mL (e.g., raw milk) or 25 g (e.g., ground beef, soft cheese, raw sausage containing beef) and 225 mL of mTSB containing Novobiocin in a stomacher and cultivate with agitation (frequency: 100/min) at 37°C for 5 to 6 h. 2. Mix 1 mL of the pre-enriched culture and 4 mL of mTSB and cultivate with agitation frequency: 180/min) at 37°C for 18 h. 3.1.2. Sewage 1. Mix 50 mL sewage and 75 mL mTSB and cultivate at 37°C with agitation (frequency: 100/min) for 18 h.
