Effect of silver nanoparticles and REP-PCR typing of Staphylococcus aureus isolated from various sources.

This is the primary study at Matrouh Governorate to unveil antibiotic resistance, biofilm formation, silver nanoparticles (Ag-NPs) effect using electron microscopy, and REP-PCR analysis of Staphylococcus aureus strains isolated from COVID-19 patients, contaminated food, and Morel's diseased sheep and goats. A total of 15 S. aureus strains were isolated; five from each of the COVID-19 patients, Morel's diseased sheep and goats, and contaminated food.

Sudden death due to enterotoxemia among Arabian camels () and associated risk factors.

Background: Sudden death is defined as an unexpected death occurring with no observed antecedent clinical signs.

Aim: The current study was performed to notice the tangible causes of sudden death among 51 out of 340 she-camels on a private farm in the eastern region of El Khafgi, Saudi Arabia.

Methods: A retrospective cohort study design was conducted to investigate the sudden death of camels through microscopic examination of fecal matter to identify the gastrointestinal parasites, analysis of whole blood thin films to diagnose blood parasites, blood culturing to recognize bacterial infection as , and macroscopic postmortem examination to identify the gastrointestinal adult worm.

Estimating the Prevalence of Foodborne Pathogen in Chicken and Its Control via Sorghum Extracts.

is a Gram-negative bacterium which is considered as the most reported cause of foodborne infection, especially for poultry species. The object of this work is to evaluate the occurrence of in chicken meat as well its control via three types of sorghum extracts (white sorghum (WS), yellow sorghum (YS), and red sorghum (RS)); antibacterial activity, antioxidant power, and cytotoxicity of sorghum extracts were also assessed. It was found that is very abundant in chicken meat, especially breast and thigh.

Detection of in Some Egyptian Fish Products, Its Control In Vitro Using Leaves Extracts, and Applicability of Leaf Extract in Tuna.

This study aims to detect and its control using natural leaf extracts of , , and in Egyptian fish products, e.g., canned tuna, canned sardine, canned mackerel, fesikh, moloha, and renga, as well the application of in tuna.

Isolation and Molecular Characterization of : Association with Proinflammatory Cytokines in Caseous Lymphadenitis Pyogranulomas.

is a causative agent of numerous chronic diseases, including caseous lymphadenitis (CLA) in sheep and goats, which has a zoonotic potential in humans in addition to a poor therapeutic response. In this study, out of 120 collected samples, only 12 (10%) were positive for by PCR and by intraperitoneal injection of male Guinea pigs and then characterized for antimicrobial susceptibility and its genetic-relatedness by enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR), which showed 2-4 bands ranging from 100 to 3000 bp that can be clustered into four clusters (C1-C4). Despite the serotype biovar 1 only infecting sheep and goats, ERIC-PCR reveals intra-subtyping variation.

Evaluation of the Prevalence of in Chicken Fillets and Its Bio-Control Using Different Seaweed Extracts.

This study aims to assess the occurrence of Staphylococcus aureus in chicken fillets and to control its growth using various lyophilized seaweed extracts (i.e., Halimeda opuntia (HO), Actinotrichia fragilis, and Turbinaria turbinata) by an agar disk diffusion assay in vitro.

Silver nanoparticle effect on Salmonella enterica isolated from Northern West Egypt food, poultry, and calves.

A total no. of 65 Salmonella enterica isolates recovered from food samples, feces of diarrheic calves, poultry, and hospital patient in large five cities at Northern West Egypt were obtained from the Department of Microbiology, Faculty of Veterinary Medicine, Alexandria University, Alexandria, Egypt. The 65 Salmonella enterica isolates had the invA gene were grouped into 11 Salmonella enterica serovars with dominance of S.
