Probiotics are increasingly documented to confer health and performance benefits across farmed animals. The aim of this study was to assess the effect of a constant daily intake of the single-strain probiotic MA18/5M (4 × 10 CFU.day.

After 30 days of rearing, juvenile shrimps were exposed to H2O2 stress at a concentration of 30 ppm during 6 h. The oxidative stress caused by H2O2 was examined in the digestive glands of the shrimp, in which antioxidant enzyme (AOE) and antimicrobial peptide (AMP) gene expression were analysed by quantitative real-time PCR.

- The study investigated how the blue shrimp Litopenaeus stylirostris responds to infection from the bacteria Vibrio nigripulchritudo by examining oxidative stress and antioxidant defenses over a 72-hour period.
- Findings showed that infection peaked in the shrimp’s blood at 24 hours post-infection, leading to increased tissue damage and significant drops in antioxidant defenses from this point onward.
- Shrimps fed a probiotic diet (Pediococcus acidilactici) exhibited lower infection and mortality rates and maintained better antioxidant levels compared to control shrimps, highlighting the probiotic's protective effects against oxidative stress.
