Strains identified in ovine cheese and bryndza by matrix-assisted laser desorption/ionization time-of-flight analysis belonged to ten species of non-enterococcal lactic acid bacteria and included Lactobacillus casei/Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus helveticus, Lactobacillus delbrueckii, Lactobacillus fermentum, Lactobacillus brevis, Lactococcus lactis, Pediococcus pentosaceus and Pediococcus acidilactici. The susceptibility toward antibiotics was determined in lactobacilli, lactococci and pediococci and also in Escherichia coli for comparison. Analysis of L. fermentum and pediococci revealed the presence of non-wild-type epidemiological cut-offs in streptomycin, clindamycin or gentamicin. E. coli were resistant to ampicillin, tetracycline, enrofloxacin and florfenicol. No extended spectrum β-lactamases were detected.
通过基质辅助激光解吸/电离飞行时间分析鉴定的绵羊奶酪和白奶酪中的菌株属于十种非肠球菌乳酸菌，包括干酪乳杆菌/副干酪乳杆菌、植物乳杆菌、鼠李糖乳杆菌、德氏乳杆菌、乳双歧杆菌、发酵乳杆菌、短乳杆菌、乳链球菌、戊糖片球菌和乳酸片球菌。比较了抗生素的敏感性，测定了乳酸菌、乳球菌和肠球菌以及大肠杆菌的敏感性。对发酵乳杆菌和肠球菌的分析显示，链霉素、克林霉素或庆大霉素存在非野生型流行切割值。大肠杆菌对氨苄西林、四环素、恩诺沙星和氟苯尼考具有抗性。未检测到扩展谱β-内酰胺酶。
