乳房炎源生鲜乳中病原微生物的污染现状及防控措施

主要介绍了乳房炎患病牛乳中病原微生物污染情况、耐药情况及防控措施。总结出乳房炎患病牛乳中的病原微生物种类较多, 主要有大肠杆菌、金黄色葡萄球菌、链球菌和克雷伯菌, 不同地区乳房炎乳样中的病原微生物不同, 产生的耐药性和耐药基因存在差异。旨在为减少因滥用和乱用抗生素导致药物残留和耐药性产生、降低乳房炎患病牛乳中病原微生物的污染以及科学、合理用药提供参考。

Pathogenic Microorganisms Associated Contamination in Raw Milk of Dairy Cows with Mastitis and Corresponding Control Measures

In this paper, the status of contamination associated with pathogenic microorganisms in raw milk of dairy cows with mastitis is introduced, the prevalence of antimicrobial resistant pathogenic microorganisms causing dairy cows mastitis is expounded, and the corresponding control measures on pathogenic microorganisms associated contamination in raw dairy milk are proposed. Many species of pathogenic microorganisms such as Escherichia coli, Staphylococcus aureus, Streptococcus spp. and Klebsiella spp. are observed in raw milk of dairy cows with mastitis. The presence of pathogenic microorganisms in mastitis milk samples are varied in different regions, and the pattern of antimicrobial resistance as well as the distribution of antimicrobial resistant determinants of the mastitis associated pathogenic microorganisms are also different. This review provides a reference for reducing drug residues and drug resistance due to abuse of antibiotics, controlling the contamination associated with pathogenic microorganisms in raw milk of dairy cows with mastitis, and improving the prudent and rational use of antibiotics.
