Summary: This study investigated the effects of different concentrations of zinc on the growth performance, morphological changes, physiological changes, and gene expression in white shrimp hepatopancreas. The results showed that high concentrations of zinc significantly reduced survival rate and growth performance, and caused structural damage and zinc accumulation in the hepatopancreas. Zinc exposure led to decreased activities of digestive enzymes and total antioxidant capacity, and increased production of reactive oxygen species and malondialdehyde. Transcriptome analysis revealed many differentially expressed genes, and qRT-PCR validation confirmed the accuracy of the results. The study demonstrated that zinc exposure caused severe histopathological changes and altered immune, antioxidant, and detoxifying responses by regulating gene expressions.

Summary: The antibacterial activity of Weissella cibaria KY10 derived from the shrimp digestive tract against Vibrio parahaemolyticus T.11 causing AHPND was investigated. The study found that W. cibaria KY10 completely inhibited the growth of V. parahaemolyticus T.11 and produced antibacterial substances, mainly consisting of higher-pKa acids. In addition, this strain showed strong auto-aggregation, hydrophobicity, and tolerance to gastric juice and bile salt. Importantly, it had no haemolysis or pathogenic effects in vivo. These findings suggest that W. cibaria KY10 has potential as an autochthonous probiotic for controlling V. parahaemolyticus causing AHPND in shrimp aquaculture.

Summary: This study used pineapple waste crude extract (PWCE) to optimize Pacific white shrimp production. The results showed that shrimp fed with PWCE supplementation had higher growth rate, improved feed utilization and yield, and higher protein content. Additionally, PWCE supplementation reduced the variation of endogenous digestive enzymes and decreased the number of microorganisms. It also had positive effects on the microvilli in the hindgut and the F-cells in the hepatopancreas of the shrimp.

Summary: This study investigates the gene expression related to nutritional accumulation in Litopenaeus vannamei during ovarian development using transcriptomic analysis. The study finds that the hepatopancreas is the major exogenous vitellogenesis site for ovarian maturation in L. vannamei, with two distinct vitellogenin genes performing exogenous and endogenous vitellogenesis in the hepatopancreas and ovary, respectively.

Summary: The parasitism of Enterocytospora artemiae resulted in the activation of genes related to DNA replication, transcription, translation, immunity, and metabolism in the hepatopancreas of Palaemonetes sinensis. Upregulation of antioxidant genes and downregulation of other immune-related genes led to a decline in the immune defense ability of P. sinensis. Meanwhile, downregulation of metabolism-related genes affected nutrient absorption and energy supply, resulting in impaired growth of P. sinensis.

Summary: Bacterial viruses are abundant in soil ecosystems, and recent advancements in metagenomics and viromics have identified a diverse range of virus-encoded auxiliary metabolic genes (AMGs) in soils. These AMGs play important roles in transforming carbon, phosphorus, and sulfur, degrading organic pollutants, and resisting antibiotics. Viral AMGs can influence soil biogeochemical processes by interfering with bacterial host metabolism, and they contribute to the adaptation of bacterial hosts in stressed soil environments. This mini-review summarizes the diversity and function of virus-encoded AMGs in the soil environment, with a focus on the evolutionary significance of AMGs involved in virus-host interactions. It also highlights the current gaps and future perspectives for research on viral AMGs in soils.

Summary: This study investigates the occurrence, transport, and risks associated with antibiotic residues, antibiotic resistance genes, and antibiotic resistant Escherichia coli in natural springs in an agroecosystem environment. The results show that tetracycline and sulfonamide residues are the most commonly found, and genes conferring resistance to sulfonamides and tetracyclines are present in most springs. Antibiotic resistant E. coli is also detected, but with poor correlations to the concentrations of antibiotic residues and genes. The occurrence of antibiotics, genes, and bacteria is influenced by seasonal variations, hydrological factors, and reactive transport processes. The risk assessment suggests a low risk for both groundwater environment and human health when spring water is used for direct consumption.

Summary: Antibiotic misuse in livestock poses a significant threat to human health due to the development of antibiotic resistance in bacteria. Through comparative analysis of faecal metagenomes from swine, poultry, cattle, and humans, we found that poultry manure had a higher prevalence of antibiotic resistance genes compared to other species. Clinically relevant resistance genes, including mcr-1 and blaCTX-M, were detected across all species. Poultry manure was identified as a hotspot for multidrug resistance, highlighting the urgent need for action in the livestock industry to combat antibiotic resistance.

Graphene oxide addition enhanced the removal of various pharmaceuticals, including those that are biological degradation persistent. However, high concentrations of graphene oxide partially inhibited methane production. The relative abundance of antibiotic resistance genes was unaffected, but there were significant changes in the microbial community.

Summary: This study investigated the interactions between earthworm intestinal phages and their bacteria under different benzo[a]pyrene (BaP) concentrations using metagenomics and metatranscriptomics. The results showed that low-level BaP stress stimulated microbial metabolism and enhanced the antiphage defense system, while high-level BaP exposure disrupted microbial metabolism and suppressed the antiphage systems. Overall, these findings expand our knowledge of complex phage-bacterium interactions in pollution-stressed worm guts and deepen our understanding of the ecological and evolutionary roles of phages.
