Enteritidis, , and are among the most common foodborne pathogens worldwide, and poultry products are strongly associated with foodborne pathogen outbreaks. These pathogens are capable of producing biofilms on several surfaces used in the food processing industry, including polyethylene and stainless steel. However, studies on multi-species biofilms are rare. Therefore, this study aimed to develop predictive mathematical models to simulate the adhesion and removal of multispecies biofilms. All combinations of microorganisms resulted in biofilm formation with differences in bacterial counts. showed the greatest ability to adhere to both surfaces, followed by Enteritidis and . The incubation time and temperature did not influence adhesion. Biofilm removal was effective with citric acid and benzalkonium chloride but not with rhamnolipid. Among the generated models, 46 presented a significant coefficient of determination (R), with the highest R being 0.88. These results provide support for the poultry industry in creating biofilm control and eradication programs to avoid the risk of contamination of poultry meat.
肠炎沙门氏菌、[此处原文缺失部分内容]和[此处原文缺失部分内容]是全球最常见的食源性病原体，禽肉产品与食源性病原体爆发密切相关。这些病原体能够在食品加工业中使用的多种表面上形成生物膜，包括聚乙烯和不锈钢。然而，关于多物种生物膜的研究很少。因此，本研究旨在开发预测数学模型，以模拟多物种生物膜的粘附和去除。所有微生物组合均导致生物膜形成，细菌数量存在差异。[此处原文缺失部分内容]表现出在两种表面上最强的粘附能力，其次是肠炎沙门氏菌和[此处原文缺失部分内容]。孵育时间和温度不影响粘附。柠檬酸和苯扎氯铵对生物膜去除有效，但鼠李糖脂无效。在生成的模型中，46个模型具有显著的决定系数（R），最高R值为0.88。这些结果为家禽行业制定生物膜控制和根除计划提供了支持，以避免禽肉污染风险。
