Các liệu pháp phòng, trị bệnh mới trong nuôi trồng thủy sản

Can Tho University Journal of Science, Год журнала: 2025, Номер 61(1)

Опубликована: Фев. 18, 2025

Sự mở rộng về quy mô của nghề nuôi trồng thủy sản đã dẫn đến dịch bệnh phát sinh ngày một phức tạp hơn. Trong khi đó, việc lạm dụng thuốc kháng để giải quyết gia tăng tình trạng thuốc, khiến các loại mạnh nhất càng mất hiệu quả. Việc tập trung nghiên cứu pháp thay thế bền vững, sáng tạo trong điều trị sẽ ra giai đoạn mới sức khỏe sản. Bài báo này nhằm mục đích tổng hợp và đánh giá số liệu mới, tiên tiến kiểm soát truyền nhiễm hiện nay. Các như thực khuẩn thể, endolysin, bacteriocin quorum quenching đang chứng minh được quả vượt trội cùng với tính an toàn cao. Bên cạnh peptide khuẩn, thể IgY, hạt nano cũng mang lại những định cho

Supplementation of Rhodotorula paludigena CM33 in Feed as Probiotic Enhances Growth, Immunity, Gene Expression, and Disease Resistance to Aeromonas hydrophila in Red tilapia (Oreochromis niloticus × O. mossambicus)

Research Square (Research Square), Год журнала: 2025, Номер unknown

Dietary supplementation with red yeast (RY) has been proposed to enhance immunity and disease resistance in fish; however, its effects tilapia remain underexplored. This study evaluated the impact of Rhodotorula paludigena CM33 on growth performance, immune responses, liver intestinal histology, gene expression, Aeromonas hydrophila tilapia. A total 300 fish were assigned five dietary groups: RY-0 (control), RY-5 (5 g/kg), RY-10 (10 RY-20 (20 RY-40 (40 g/kg). Growth performance was assessed at weeks 4 8. At week 8, blood serum, liver, samples collected for histological expression analyses. Fish then challenged A. an LD₅₀ dose 10⁵ CFU/fish via intraperitoneal injection. Results showed that R. significantly improved polynomial regression identifying ~ 24 g/kg as optimal, experimental fed 20 achieved highest weight, gain, feed efficiency. Antioxidant responses enhanced, evidenced by increased ABTS radical scavenging activity, superoxide dismutase upregulation immune-related antioxidant genes (IL1, MHC, LBP, GSR, GPX, IGF, HSP70, TNF). Histological analysis revealed enhanced structure hepatocyte integrity, exhibiting elongated villi reduced hepatic vacuolation compared control. Kaplan-Meier survival confirmed greater inclusion level. These findings highlight a promising supplement enhancing growth, function,

Genomic Characterization of Bacillus sp. THPS1: A Hot Spring-Derived Species with Functional Features and Biotechnological Potential

Microorganisms, Год журнала: 2024, Номер 12(12), С. 2476 - 2476

Опубликована: Дек. 2, 2024

Bacillus sp. THPS1 is a novel strain isolated from high-temperature hot spring in Thailand, exhibiting distinctive genomic features that enable adaptation to an extreme environment. This study aimed characterize the and functional attributes of understand its strategies evaluate potential for biotechnological applications. The draft genome 5.38 Mbp with GC content 35.67%, encoding 5606 genes, including those linked stress response sporulation, which are essential survival conditions. Phylogenetic analysis average nucleotide identity (ANI) values confirmed classification as distinct species within genus. Pangenome involving 19 others closely related thermophilic identified 1888 singleton genes associated heat resistance, specialized metabolism, suggesting nutrient-deficient, environments. Genomic revealed 12 biosynthetic gene clusters (BGCs), polyketides non-ribosomal peptides, highlighting synthesizing secondary metabolites may facilitate adaptation. Additionally, presence three Siphoviridae phage regions 96 mobile genetic elements (MGEs) suggests significant plasticity, whereas existence five CRISPR arrays implies advanced defense mechanism against infections, contributing stability. capacities make it promising candidate applications, particularly production heat-stable enzymes development resilient bioformulations.
