A 16-week feeding trial was conducted to examine the effects of dietary exogenous bile acids (BAs) on growth performance, digestive enzyme activities, biochemical indices, antioxidant capacity, non-specific immune response, gene expression of proinflammatory cytokines, and liver and intestinal morphology in Nile tilapia (initial weight, 5.10 ± 0.22 g) reared in earthen ponds over an extended period. Two isonitrogenous (31.65%...

Despite the beneficial therapeutic effects of tamoxifen (TAMX) against breast cancer, long-term treatment with TAMX enhances the development of metabolic dysfunction-associated steatotic liver disease (MASLD), including steatohepatitis. Bempedoic acid (BA) is a recently approved lipid-lowering drug for dyslipidemia. Our study aimed to examine the potential impact of BA against TAMX-induced steatohepatitis in rats and underline...

Improving sperm quality is essential for enhancing the reproductive efficiency of Oreochromis niloticus . This study evaluated the effect of three dietary antioxidant supplements, kaolinite-doped zinc oxide (ZnO-K), citrus essential oil (CEO), and pumpkin seed oil (PSO), on sperm quality parameters. A suite of integrative assessments, including Computer-Assisted Semen Analysis (CASA) parameters, spermatozoa DNA integrity, anti...

Identifying novel natural sources from the marine environment with unique immunomodulatory and antioxidant efficacies is of interest in intensive fish farming. In this sense, marine sponge extract derived from Smenospongia (SS-extract) was tested for its potential anti-inflammatory, antioxidant and antimicrobial activities during the concurrent infection with Trichodina sp. and Flavobacterium columnare in Nile tilapia. A total...

This study investigated the genotype classification and pathogenicity of infectious bursal disease virus (IBDV) circulating in vaccinated broiler chicken farms in Egypt. A total of 150 samples were collected from 30 vaccinated commercial broiler chicken farms and pooled into 30 working samples. IBDV was tested using reverse transcriptase polymerase chain reaction (RT-PCR) amplification of the hypervariable region of the viral...

In the current study, nano-silica oxide (nano-SiO 2 ) was fabricated via the sol-gel technique. Then, the prepared nano-SiO 2 was characterized using X-ray diffractometer (XRD), transmission electron microscopy (TEM) coupled with energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) specific surface area analysis. Furthermo...

Listeria monocytogenes ( L. monocytogenes ) is frequently detected in ruminants, especially dairy cattle, and associated with the sporadic and epidemic outbreak of listeriosis in farms. In this epidemiological study, the prevalence, virulence, antibiotic resistance profiles, and genetic diversity of L. monocytogenes in three Egyptian dairy cattle farms were investigated. The risk factors associated with the fecal shedding of L...

Continue to hypothesize that honey is a storehouse of beneficial bacteria, and the majority of these isolates are levansucrase producers. Accordingly, ten bacterial strains were isolated from different honey sources. Four honey isolates that had the highest levansucrase production and levan yield were identified by the partial sequencing of the 16S rRNA gene as Achromobacter sp. (10A), Bacillus paralicheniformis (2M), Bacillus...
