“…L. acidophilus are commonly used in aquaculture as a biological control to protect various shrimp species from Vibrio spp. Lactobacillus acidophilus 04 was observed to significantly reduce the CMR% of shrimp in water bath experiments with Vibrio harveyi, Vibrio vulnificus or Vibrio europaeus 20 . In a previous study, the addition of Mushroomella pentospora BD6 (10 10 CFU/kg diet) to the diet for 60 consecutive days significantly increased the immune indices, i.e., PO and lysozyme activity (LYZ) in Vanamey carp.The expression of the Propoxygenase I (proPO I) gene was also significantly increased 21 .…”

In this study, Penaeus monodon were gave basic feed supplemented with three levels of Enterococcus faecium. Then, the expression of non-specific immunity-related genes, and the activities of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), malondialdehyde (MDA), acid phosphatase (ACP), alkaline phosphatase (AKP), phenol oxidase (PO) were evaluated. Meanwhile, the disease resistance test and intestinal flora determination were conducted. The results showed that the MDA levels of 2% and 5% E. faecium groups were significantly lower than that of the control group (P < 0.05). While the SOD and T-AOC and ACP and AKP of experimental groups were significantly higher (P < 0.05), the PO of experimental groups were significantly lower than that of the control group (P < 0.05). In addition, the expressions of immunity-related genes (tlr22, dorsal, lysozyme, crustin, imd, and relish) in the 2% and 5% E. faecalis groups were significantly greater than those in the control group (P < 0.05). After P. monodon was challenged with Vibrio parahaemolyticus for 7 days, the average cumulative mortality of P. monodon in the 2% and 5% groups were significantly lower than that in the 0% group (P < 0.05). With the increase of feeding time, the number of effective OTUs in each group showed a downward trend. At the 14th d, Proteobacteria, Bacteroidetes and Firmicutes, the dominant flora in the intestinal tract of P. monodon. In summary, supplied with E. faecium could increase the expression of non-specific immunity-related genes, enhance the immune capacity of P. monodon.

Shrimp aquaculture is the rapidly growing sector of fish culture producing sectors in the world due to its rising demand in developed countries. Moreover, the intensive and extensive shrimp culture systems are affected mainly by infection diseases caused by several pathogenic agents and resulting in high economic losses. Nowadays, controlling and preventive infection diseases are the major concern to develop this sector. Besides, the highly extensive usage of chemotherapeutics and antibiotics induced numerous drawbacks in shrimp farming, developed antibiotic resistance bacterial strains, and threatens the aquatic life. Recently, improving the immunity status and controlling infectious diseases using biological methods have become beneficial, environment friendly, and risk-free options in aquaculture. Probiotics have gained much attention as immunostimulants in aquaculture owing to their inhibitory properties on pathogenic microorganisms via creation of an unfriendly atmosphere to cease their growth. Lactobacillus species as probiotics was used in shrimp aquaculture to prevent viral infections due to their positive promoting effects on survival and health. Additionally, Lactobacillus species possesses sturdy antimicrobial activity against various pathogenic microorganisms such as Photobacterium and Vibrio infections. This review threw the light on the applications of Lactobacillus sp. as probiotics in cultured shrimp which could be of great impact from a sustainable, intensive, and ecofriendly aquaculture opinion.
