The present study proposed to evaluate the breadth of antibiotic resistance among psychrotrophic bacteria spoiling raw milks in Finland. A core of 60 isolates, retrieved from farms, trucks, and silos, phenotypically characterized, were analysed with ATB PSE strips, composed of a panel of 17 beta-lactams and non-beta-lactams antibiotics, representatives of five classes. Surprisingly, 60% of the psychrotrophs harboured multiresistant traits. We observed an increase of this feature along the cold chain of raw milk transportation.
本研究旨在评估芬兰生鲜牛奶中嗜冷菌的抗生素耐药广度。从农场、卡车和筒仓中收集了60株菌株作为核心样本，对其进行了表型特征分析，并用ATB PSE试纸条进行分析，该试纸条由17种β-内酰胺类和非β-内酰胺类抗生素组成，代表了五类抗生素。令人惊讶的是，60%的嗜冷菌具有多重耐药特性。我们观察到这种特性在生鲜牛奶运输冷链中有所增加。
