Abstract

Abstract The objective of this work was to evaluate the antimicrobial activity of four new potassium monopersulfate-based products on bacterial biofilms associated with avian infections, in order to disinfect drinking fountains in poultry farms. Initially, tests were performed in planktonic bacterial cells, to verify the antimicrobial activity and the minimum inhibitory concentration of the products, named PA, PB, PC, and PD. These products were tested on mature biofilms of the avian pathogens Escherichia coli, Salmonella enterica subsp. enterica serovar Enteritidis, and Listeria monocytogenes, grown on specimens preserved in acrylic blocks, by counting colony-forming units, scanning electron microscopy, and confocal fluorescence microscopy. All products were effective against the evaluated bacterial species. The PA and PB products inhibited the bacterial growth at ≤ 0.13% concentrations, and PC and PD showed the same effect at ≤ 0.25% concentrations. Furthermore, the PA product was able to eliminate mature biofilms of S. enterica subsp. enterica serovar Enteritidis and L. monocytogenes. The evaluated monopersulfate-based products, notably PA, are effective against bacterial biofilms associated with avian infections and show potential as sanitizers and disinfectants for drinking fountains in poultry farms.

过硫酸钾产品对禽类感染相关细菌的抑菌活性研究
摘要本研究旨在评价四种新型单过硫酸钾基产品对禽类感染相关细菌生物膜的抑菌活性,以期对家禽养殖场饮水机进行消毒。最初,实验在浮游细菌细胞中进行,以验证抗菌活性和产品的最低抑制浓度,命名为PA, PB, PC和PD。这些产品在禽致病菌大肠杆菌、肠沙门氏菌亚种的成熟生物膜上进行了检测。通过计数菌落形成单位,扫描电子显微镜和共聚焦荧光显微镜,在丙烯酸块保存的标本上生长的血清型肠炎肠杆菌和单核增生李斯特菌。所有产品对所评价的细菌种类均有效。PA和PB产物在≤0.13%的浓度下抑制细菌生长,PC和PD在≤0.25%的浓度下抑制效果相同。此外,PA产物还能消除肠链球菌的成熟生物膜。血清型肠炎和单核增生乳杆菌。所评估的以过硫酸盐为基础的产品,特别是PA,对与禽类感染有关的细菌生物膜有效,并显示出作为家禽养殖场饮水机消毒剂的潜力。
