“…Conversely, the bacterial balance in shrimp intestines is disrupted by challenge with pathogenic Vibrio harveyi (Rungrassamee et al 2016). In particular, the deviations in intestinal bacterial communities are closely correlated with disease severity in shrimp (Xiong et al 2015b), whereas a recovery of the intestinal bacterial composition (Rungrassamee et al 2016). Collectively, these previous findings illustrate that intestinal bacterial assemblages are indicative of shrimp health status, mirroring what has been observed in human (Clemente et al 2012;Round and Mazmanian 2009).…”

“…Recent works have shown that shrimp diseases are induced by an imbalance between increasing potential pathogens and decreasing candidate probiotics (Rungrassamee et al 2016;Xiong et al 2014b). There is a strong indication that bacterioplankton abundance and composition play direct roles in numerous shrimp diseases (Lucas et al 2010;Xiong et al 2014b).…”

“…For example, increased Helicobacter pylori abundance indicates a high potential for gastric adenocarcinomas (Lathrop et al 2011), while a decreased Firmicutes/Bacteroidetes ratio can indicate inflammatory bowel disease (Spor et al 2011). By contrast, comparable integration between intestinal bacterial assemblages and shrimp health is only in its infancy with the recent advances in metagenomic technologies (Rungrassamee et al 2016;Xiong et al 2015b). Given that the shrimp intestinal community is dominated by Proteobacteria (Rungrassamee et al 2014;Xiong et al 2015b), as opposed to mammalian intestines that are dominated by Bacteroidetes and Firmicutes (Clemente et al 2012;Lozupone et al 2012), we might expect the relationship between intestinal microbiota with its host to differ from that in the mammalian systems, upon which most attention has been focused.…”

“…Furthermore, the application of probiotics significantly decreased Vibrio abundance and simulated immune response in shrimp (Li et al 2007). Conversely, the bacterial balance in shrimp intestines is disrupted by challenge with pathogenic Vibrio harveyi (Rungrassamee et al 2016). In particular, the deviations in intestinal bacterial communities are closely correlated with disease severity in shrimp (Xiong et al 2015b), whereas a recovery of the intestinal bacterial composition (Rungrassamee et al 2016).…”

“…If any, the magnitude of deviation from normal composition might indicate the incidence (Xiong et al 2014b) and severity (Xiong et al 2015b) of shrimp disease. Although the causal relationship between community dynamics and invisibility is uncertain, recent studies have repeatedly shown that the disruption of the intestinal community is closely associated with shrimp disease severity (Rungrassamee et al 2016;Xiong et al 2015b). In particular, the intestinal microbiota of zebrafish is stage specific (Roeselers et al 2011;Stephens et al 2016).…”

High-density aquaculture has led to increasing occurrences of diseases in shrimp. Thus, it is imperative to establish effective and quantitative strategies for preventing and predicting these diseases. Water quality indices and investigations of specific pathogen abundance provide only a qualitative evaluation of the risk of shrimp disease and can be inaccurate. To address these shortcomings, we introduced intestinal indicative assemblages as independent variables with which to quantitatively predict incidences of shrimp disease. Given the ignorance regarding the niches differences in the shrimp intestine throughout its developmental stages, the use of probiotics in aquaculture has had limited success. Therefore, we propose the exploration of effective probiotic bacteria from shrimp intestinal flora and the establishment of therapeutic strategies dependent on shrimp age. Following ecological selection principles, we hypothesize that the larval stage provides the best opportunity to establish a desired gut microbiota through preemptive colonization of the treated rearing water with known probiotics. To employ this strategy, however, substantial barriers must be overcome.

Nitrite stress disrupts the structural integrity and induces oxidative stress response in the intestines of Pacific white shrimp Litopenaeus vannamei

et al. 2018

The acute toxicity of nitrite on the mucosal morphology and oxidative stress response was investigated in the intestines of Litopenaeus vannamei after the exposure of 20 mg/L nitrite for 72 hr. The duration of nitrite stress influenced the shrimp survival, and the cumulative mortality rate was 36.7% at 72 hr. Hematoxylin and eosin (HE) stain showed that nitrite stress damaged the intestine connective and epithelium tissue. Specifically, nitrite stress increased the content of reactive oxygen species (ROS) production (O generation capacity), lipid peroxidation (LPO), and malondialdehyde (MDA). Meanwhile, the activities of antioxidant enzymes including superoxide dismutase (SOD) increased first, then catalase (CAT) and glutathione peroxidase (GPx) increased to the highest at 24 and 12 hr, respectively. The relative expression level of antioxidant genes including heat shock protein 70 (HSP70), ferritin, and thioredoxin (Trx) increased to the highest at 6, 12, and 48 hr respectively. After exposure to nitrite stress for 72 hr, the levels of antioxidant enzymes activity and genes expression all decreased. These results revealed that nitrite stress harmed the intestine barrier of L. vannamei by damaging the mucosal structure, inducing the oxidative stress, and confusing the antioxidant status.

This study assessed the intestinal microbiota of juveniles of the White shrimp Litopenaus vannamei, whose feed was enriched with three probiotic formulations: Streptomyces sp. RL8 (RL8); a mix of Lactobacillus graminis and Streptomyces spp. RL8 and N7 (Lac‐Strep); and a mix of Bacillus spp. and Streptomyces spp. RL8 and N7 (Bac‐Strep). The analysis was performed by sequencing the V3 region of the 16S rRNA gene of treated animals and the control group before and after Vibrio parahaemolyticus challenge. After challenge, the highest Shannon diversity indexes corresponded to RL8 and Bac‐Strep (3.94 ± 0.11 and 3.39 ± 0.3, respectively) and the lowest to the control group (2.58 ± 0.26). The most abundant phyla before and after challenge were Proteobacteria, Actinobacteria, and Bacteroidetes. The principal component analysis and Statistical Analysis of Metagenomic Profiles (STAMP) showed that the gut microbiota of the groups RL8 and Bac‐Strep after challenge was different from the other experimental groups, which was characterized by a higher bacterial diversity, as well as a significant stimulation of the Bacteriovorax population and other antimicrobial producing genera that protected shrimp from infection.
