摘要

Two new miniaturized methods (sandwiched microtiter plate [SMP] and mini‐tube) for recovery of Clostridium sporogenes from food samples were developed and evaluated. One hundred microliter of SFP (Shahidi Ferguson Perfringens) agar and 10 üL of diluted food sample were used in the SMP anaerobic system. The samples were sandwiched between two sterile microtiter plates to create an anaerobic environment. Black colonies in the sandwiched wells were counted as C. sporogenes. In case of mini‐tube system, 1 mL of SFP agar (45C) containing diluted food sample was aspirated into a 1.2 mL sterile pipet and allowed to solidify in place. The two ends are sealed to create an anaerobic environment. Black colonies were counted directly through the plastic tube. C. sporogenes was inoculated into ground beef samples for recovery study. The recovery rates in SFP agar, using the SMP and mini‐tube method were compared with the double‐tube method. Organisms were recovered more in the double‐tube than with SMP method and mini‐tube method after 24–30 h incubation. However, the final counts at 48 h were similar in all methods from the food samples. These new simple methods have potential use for recovery of C
