Molecular characterization and immunopathological investigation of Avian reticuloendotheliosis virus in breeder flocks in Egypt.

Background: Reticuloendotheliosis virus (REV) is an oncogenic immunosuppressive retrovirus that infects different kinds of avian species; posing significant economic losses to the poultry industry worldwide.

Methods: In Egypt, there is an unidentified disease associated with the runting-stunting syndrome with neoplasia, suspected to be REV, that has been continuously monitored in several breeder flocks. To diagnose and analyze REV by cell cultures, enzyme-linked immunosorbent assay (ELISA), histopathological investigation, the polymerase chain reaction (PCR) test, and sequencing analysis, 200 blood samples, and 50 tissue specimens were collected.

Involvement of Goose Parvovirus in Induction of Angel Wing Syndrome in Muscovy Ducks.

Dietary, environmental, and hereditary causes were reported as causative agents of angel wing syndrome in waterfowl. Since 2017, several Muscovy duck flocks at Behira governorate were found to exhibit this syndrome associated with the clinical symptoms of goose parvovirus (GPV) infection. Four strains of goose parvovirus named HS1-HS4 were isolated and identified from diseased ducks at some of these flocks.

Molecular and genetic detection of infectious laryngeotrachitis disease virus in broiler farms after a disease outbreak in Egypt.

Infectious laryngotracheitis (ILT) is a viral respiratory illness in poultry that causes massive financial losses. This research aimed to isolate and identify the ILT virus in suspected outbreaks of broiler flocks in Egypt during 2020-2021, besides investigating its genetic link with other circulating strains. Real-time-PCR was used to test 57 samples taken from unvaccinated broiler farms.

Effect of Nigella sativa, atorvastatin, or L-Carnitine on high fat diet-induced obesity in adult male Albino rats.

Obesity is increasing rapidly across the globe. It is widely accepted that natural products with a long safety background may modulate obesity. The current work aimed to investigate the effect of Nigella sativa, atorvastatin, or L-Carnitine on high-fat diet-induced obesity in white male albino rats.

The ameliorative effect of atorvastatin on serum testosterone and testicular oxidant/antioxidant system of HFD-fed male albino rats.

: There is a mutual effect between central obesity and low total serum testosterone. Moreover, oxidative stress acts as a bridge between obesity and its complications. Taken together, we aimed to evaluate whether atorvastatin (AS), a cholesterol-lowering drug, has protective potential against high fat diet (HFD)-induced low fertility, which was exemplified in serum testosterone determination.

Role of identified bacterial consortium in treatment of Quhafa Wastewater Treatment Plant influent in Fayuom, Egypt.

This study was aimed to biologically treat domestic wastewater using identified bacterial consortium for chemical pollutants removal by treating/passing it through sand biofilters. The identification, toxicity test, and the optimum dose of the investigated bacterial consortium were carried out using Microtox analyzer and Batch biological treatment, respectively. Furthermore, application of sedimentation followed by gravel and sand biofilters for wastewater treatment was evaluated.
