is a zoonotic emerging food and waterborne pathogen widely distributed in nature. It is present in food processing environments and can easily be spread through the food industry because of its ability to form biofilm. The aim of this work was to determine the ability of strains isolated in Costa Rica from different food matrixes of animal origin to form biofilm. Thirty-eight strains previously isolated and identified from animal origin products were analyzed using the method described by Stepmovic (2000), in three culture broths, brain heart infusion broth, Boer broth and Houf broth. Results showed that 67% of poultry origin strains, 62.5% of meat origin strains and just 8% of milk origin strains showed ability to form biofilm. The findings of this study confirm the adherence ability of to form biofilm, a characteristic that can promote dispersion and cross contamination along food industry processing lines.
是一种人畜共患的新兴食源性病原体和水源性病原体,在自然界中广泛分布。它存在于食品加工环境中,由于其形成生物膜的能力,很容易在食品工业中传播。这项工作的目的是确定在哥斯达黎加从不同动物源食品基质中分离出的菌株形成生物膜的能力。使用Stepmovic(2000年)描述的方法,在三种培养基(脑心浸液肉汤、布尔肉汤和胡夫肉汤)中对先前从动物源产品中分离和鉴定的38株菌株进行了分析。结果表明,67%的家禽源菌株、62.5%的肉类源菌株和仅8%的牛奶源菌株显示出形成生物膜的能力。本研究结果证实了形成生物膜的黏附能力,这一特性可促进食品工业加工生产线中的扩散和交叉污染。
