本研究主要利用Gompertz模式分別配適Listeria monocytogenes 及 Yersiniaenterocolitica 於不同溫度貯存 (4-34 ℃ ) 之熟雞肉系統中， 以純菌或混菌接種後之生長曲線， 再由生長曲線所獲得比生長速率之參數值， 並與病原菌模式程式 (PathogensModeling Program； PMP) 系統所得比生長速率之參數值，利用 Zwietering 模式描述其比生長速率與溫度之關連性， 並利用殘均方 (MSE)、 迴歸係數 (R ?? )、 偏估因子 (biasfactor) 及準確因子 (accuracy factor) 驗證模式的適用性。 研究結果顯示， 利用Zwietering 模式可適當描述 L. monocytogenes 及 Y. enterocolitica 於雞肉系統中以純菌、混菌接種及 PMP 系統中其比生長速率與溫度之關連性。比兩種病原菌藉 PMP 所得比生長速率之預測值皆高於接種於純菌或混菌之雞肉系統中之預測值。 L. monocytogenes 於 4℃貯存之雞肉中幾乎沒有生長，而於 10-34 ℃貯存之混菌雞肉系統中，Y. enterocolitica則會抑制 L. monocytogenes 之生長，致使 L. monocytogenes 的最大菌量較於純菌系統時為低。

　　　　　In this study, growth rate models of the Listeria monocytogenes andYersinia enterocolitica were compared in cooked chicken meat. The chicken meatwas inoculated with the pure culture or mixed cultures of these pathogens andstored at 4-34 ℃. After the growth curves of these two pathogens were obtained,the modified Gompertz function was then fitted to the experimental curves. Theparameter of specific growth rate was described by the Zwietering model. Themodels predicting the growth the these pathogens in chicken meat and parametersgenerated by pathogens modeling program (PMP) were then compared using themathematical and statistical parameters such as mean square error (MSE),regression coefficient (R ?? ), bias factor, and accuracy factor. The Zwieteringmodel was found to be suitable for predicting the specific growth rate of L.monocytogenes and Y. enterocolitica in the chicken meat and parameters generatedby PMP. In addition, the predicted value for the pathogens in the PMP was higherthan that in the chicken meat. No growth was observed when L. monocytogenes wsinoculated in chicken meat and stored at 4 ℃. In the presence of Y.enterocolitica, the growth of L. monocytogenes was competitively inhibited inchicken meat at the temperatures ranging from 10-34 ℃.
