The present study aimed to address the capability of the probiotic bacterium Lactobacillus rhamnosus IMC 501^® to survive in seawater and the ability of Artemia metanauplii to incorporate it, as well as to analyse the potential effect of the probiotic as a control agent for potentially pathogenic Vibrionaceae bacteria in Artemia. The results demonstrate the ability of L. rhamnosus IMC 501^® to survive in seawater for up to 30 h. They also advocate their capability to be efficiently incorporated into Artemia metanauplii at concentrations of 10⁴ CFU per Artemia after 30 min of suspension in probiotic solution, thereby promoting a 1-log reduction in Vibrionaceae levels after 3 h. These low levels of Vibrio bacteria were maintained for about 30 min after transfer into clear seawater, a sufficient time for Artemia to be ingested by aquatic organisms. These results contribute to broaden the knowledge on the suitability of probiotics as sustainable alternatives for the prevention/reduction of diseases in aquaculture facilities.

使用益生菌鼠李糖乳杆菌 IMC 501 作为控制卤虫丰年虾中弧菌的策略

本研究旨在解决益生菌鼠李糖乳杆菌IMC 501 ^®在海水中存活的能力以及卤虫吸收它的能力，并分析益生菌作为潜在致病弧菌科控制剂的潜在影响卤虫中的细菌。结果证明了鼠李糖乳杆菌IMC 501 ^®在海水中存活长达 30 小时的能力。他们还主张其能够以10 ^{4 的}浓度有效地并入卤虫 在益生菌溶液中悬浮 30 分钟后每个卤虫的 CFU，从而促进 3 小时后弧菌科水平降低 1-log。这些低水平的弧菌细菌在转移到清澈的海水中后会维持约 30 分钟，这足以让卤虫被水生生物摄取。这些结果有助于拓宽关于益生菌作为预防/减少水产养殖设施疾病的可持续替代品的适用性的知识。
