乳腺炎是奶牛的常见病,通常需要抗生素治疗,因此不可避免地造成牛奶中的抗生素残留。由于免疫传感器是将高灵敏的传感器技术与抗原、抗体特异性反应相结合的一种检测方法,易于实现抗生素残留检测仪器的便携化、微型化和自动化,因而成为近年来研究的热点。本文介绍免疫生物传感器的基本原理、组成与分类,重点介绍国内外应用免疫传感器检测牛奶中抗生素残留的研究进展,并分析未来免疫生物传感器的发展趋势。 相似文献

In this study, we developed a microbiological inhibition method for the rapid screening of antibiotics in milk with Geobacillus stearothermophilus ATCC12980 as an indicator bacterium and an easy sample pretreatment. We observed that the limits of detection of the kit for 34 common antibiotic residues in milk, including β-lactams (13), aminoglycosides (6), tetracyclines (4), sulfonamides (6), macrolides (4), lincosamides (1), were lower than or close to the maximum residue limits formulated by the European Union and China. Moreover, the false-positive rate was 1% and the false-negative rates were less than 5%. The ruggedness of the method (the reproducibility of detection capability of different batches of medium) met requirements at determined levels and residual limits. The shelf life of the kit was more than 6 mo at 4°C. Additionally, we observed good correlations between the kit results and ultra-high-performance liquid chromatography-tandem mass spectrometry results for incurred milk (samples taken from animals treated with antibiotics according to the pre-slaughter medication data), which indicated that the kit was reliable for screening antibiotics in incurred samples. In conclusion, the kit has a broad application potential with high sensitivity, specificity, and reproducibility, stability, and reliability, combined with simple operation, low cost, and high-throughput capacity. 相似文献

目的建立一种简单、准确的检测牛乳中抗生素残留的方法-乳酸菌发酵法。方法以接种量和温度为变量,优化发酵条件;以青霉素为目标抗生素,建立检测方法;以发酵4 h未凝乳的样品中抗生素最低浓度为检测限,测定本方法对20种抗生素的检测限;对比本方法和GB/T 4789.27方法检测111个商品乳样品中抗生素残留检出率,验证本方法的准确性。结果建立了乳酸菌发酵法检测乳中抗生素残留的具体方法;确定了本方法对8类20种抗生素的检测限,其中4类12种抗生素的检测限低于其在牛乳中的最大残留限量(MRL);本方法和GB/T 4789.27方法检测111个商品乳样品抗生素残留检出率分别为9.0%和11.7%。结论本方法操作简单,结果准确,适合企业及基层检测单位作为初筛方法检测牛乳中的抗生素残留。 相似文献

In the present study, 199 raw milk samples were analysed for beta-lactams, tetracyclines, sulfonamides and quinolones. They were obtained from collection tanks of milk routes in 10 provinces of China. The occurrence and concentration range of the four antibiotics were investigated by competitive enzyme-linked immunosorbent assay methods. At the detectable level, 0.5%, 47.2% and 20.1% of samples were positive for beta-lactams, quinolones and sulfonamides, respectively. No sample was positive for tetracyclines. Beta-lactams were positive only in Beijing while quinolones and sulfonamides were positive in all provinces. One (0.5%) sample for beta-lactams was above the maximum residue limits (MRLs, regulated by EU, CAC and China). The maximum concentrations for sulfonamides and quinolones were 16.28?µg?kg–1 and 23.25?µg?kg–1 which were under their maximum residue limits. More precaution should be taken on antibiotic controls because of the high detection rate of some antibiotics. 相似文献

乳及乳制品的抗生素和其他兽药残留问题 总被引:3,自引:1,他引:3
对我国牛乳抗生素及其他兽药残留问题进行了文献调查和初步现场调查。“无抗乳”风波无疑为我国众多乳品企业敲响了警钟,“无抗”和“限抗”业已成为食品国际市场进入准则,也必将在国内成为市场准入规则;我国相关政府部门也加紧了完善法规、标准及管理的工作,提出了近期乳业发展规划,重点也是保证和提高乳及乳制品的品质和安全性:总之,虽然目前在我国不能完全实现“无抗乳”,但乳品企业、养殖业及其管理部门都应该引起足够的重视,因为在不远的将来,“无抗”和“限抗”势在必行。 相似文献
