Suppression of Streptococcosis and Modulation of the Gut Bacteriome in Nile Tilapia (Oreochromis niloticus) by the Marine Sediment Bacteria Bacillus haynesii and Advenella mimigardefordensis

Abstract

Nile tilapia ( Oreochromis niloticus ) is one of the most economically important cultured fish species throughout the world. Streptococcosis is a significant threat to global Nile tilapia farming. Enterococcus faecalis has recently emerged as an important pathogen of streptococcosis in Asia and Africa.

Biological activities and metabolic profile of endophyticBacillus haynesiifromMomordica charantia

“…In contrast, cis-9-hexadecenal is reported for antifungal activity against Aspergillus fumigatus [66]. Several studies report the antimicrobial activity of B. haynesii strains isolated from variety of sources such as plants and marine soil [35, 67]. These results indicate a possibility of utilizing the endophyte for the production of such antimicrobial compounds.…”

Novel Sources of Biodiversity and Biomolecules from Bacteria Isolated from a High Middle Ages Soil Sample in Palermo (Sicily, Italy)

“…In this regard, recent examples of the successful isolation from soil of bacteria producing interesting and promising biomolecules (e.g., compounds with antibacterial, antifungal, antiviral, anti-inflammatory, and anticancer activities) are available in literature ( 17 – 22 ). For instance, such bacteria have been shown to inhibit growth of human and animal pathogenic microorganisms ( 23 – 26 ). Notably, most of the isolated producer bacteria belong to the phylum Actinomycetota , in particular to the genus Streptomyces ( 27 , 28 ).…”
