Little is known about the environmental conditions that allow Francisella noatunensis subsp. orientalis, a worldwide emergent bacterial fish pathogen, to colonize and infect wild and cultured fish. We evaluated the effect of temperature and salinity on the infectivity of F. noatunensis subsp. orientalis in Nile tilapia Oreochromis niloticus (L). Immersion challenges of tilapia with F. noatunens...

Glyphosate-based herbicides are widely used in agricultural fields and are commonly applied in fish ponds to control algae and plant growth. Nile tilapia, Oreochromis niloticus L., fingerlings exposed to the highest sublethal concentrations of glyphosate alone experienced an increase in cortisol levels that was similar to the value found in the stressed group. In contrast, fingerlings exposed t...

Tilapia tilapinevirus or tilapia lake virus (TiLV) is an emerging that inflicts significant mortality on farmed globally. Previous studies reported detection of the in multiple organs infected fish; however, little known about in-depth localization central nervous system. Herein, we determined distribution TiLV entire brain experimentally Nile tilapia. In situ hybridization (ISH) using TiLV-spe...

Tilapia lake virus (TiLV) is the main tilapia-infecting worldwide, causing serious economic losses to tilapia aquaculture. However, there no vaccine for this viral disease. Here, TiLV ORF10 (TiLV-ORF10) encoding a protein with abundant epitopes was cloned into eukaryotic expression vector pcDNA3.1 as candidate, and then used evaluate protective effects against in Nile (Oreochromis niloticus). R...

The demand for new materials and technologies that are able to minimize the environmental impact generated by disposal of from fossil sources has increased significantly in past y...

The objective of this research was to evaluate the effect increasing levels associated glutamine and glutamic acid on growth performance intestinal development Nile tilapia, Oreochromis niloticus, fingerlings. Five isoproteic (~344.70 g kg−1 crude protein) isocaloric diets (~3,925 kcal gross energy) were developed containing 0, 5, 10, 15, or 20 in extruded diets. Fish (n = 2,000, mean body weig...
