In a context of antibiotic reduction in feed, there is a need for natural, profitable and proven solutions for poultry production. Probiotic bacteria which exert a positive effect on the digestive microflora balance and gut development can help improve laying performance. The lactic acid bacteria Pediococcus acidilactici MA 18/5M, producing a high level of lactic acid, is one of the most studied probiotic bacteria with more than 40 scientific publications in monogastric feeding. Its modes of action are well-documented.

In this study, we investigated the risk associated with suspension of probiotics administration in tilapia. Tilapias were fed for 14 days using a probiotics-supplemented diet, followed by a three-day suspension of probiotics treatment and a subsequent challenge by Aeromonas hydrophila. Unexpectedly, the suspension of a probiotic strain Lactobacillus plantarum JCM1149 significantly triggered susceptibility of the host to A. hydrophila.
