Abstract Climate change has emerged as a major pressing global issue with far-reaching implications for human health, such the emerging and spread of food-borne pathogens. Food-borne pathogens are microorganisms that can cause illness in humans, from mild discomfort to life-threatening diseases, through consumption contaminated food or water. The impact climate on is multifaceted includes changes environment, agriculture, behavior. This review article examines effect pathogens, explores...
This study investigated how enzymatically modified lysozyme added to yogurt can improve its antioxidant activity and quality properties during cold storage. For this purpose, hen egg white native (LZ) was hydrolyzed with trypsin, creating a functional tryptic hydrolysate peptide (LZT). The obtained exhibited the highest compared Lysozyme. LZ LZT were in 0.4% concentration made (YLZ YLZT, respectively). treated control groups stored at 4 °C for 28 days, their activity, sensory,...
Background and Aim: The majority of animal-derived food safety studies have focused on foodborne zoonotic agents; however, members the opportunistic Enterobacteriaceae (Ops) family are increasingly implicated in public health crises due to their robust evolution acquiring antimicrobial resistance biofilms, consequently require thorough characterization, particularly Egyptian sector. Therefore, this study aimed determine distribution prevalence foods, as well important antimicrobials...
Pseudomonas spp are considered a common milk-associated psychotropic bacteria, leading to milk deterioration during storage; therefore, our study aimed the distribution of aeruginosa in raw and its associated products then studying growth behavior P. after employing chitosan nanoparticles (CsNPs 50, 25, 15 mg/100ml) selenium (SeNPs 0.5, 0.3 0.1 as trial control bacterial five days cooling storage. Our relies on ion gelation method green synthesis for conversion nanosized particles...
The primary goals of this cross-sectional study were to screen various food/water, and human samples for the presence Salmonella species, assess phenotypic genetic relationship between resistances found in food isolates critically important antibiotics. Between November 2019 May 2021, 501 randomly collected isolation identification using standard culturing methods, biochemical, matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF MS) PCR techniques....
Abstract Foodborne illnesses and microbial food contamination are crucial concerns still issues of great worldwide concern. Additionally, the serious health hazards associated with use chemical preservatives in technology. Lysozyme (Lz) is an active protein against Gram-positive bacterial cell wall through its muramidase lytic activity; however, several authors could identify some antimicrobial peptides derived from Lz that have exaggerated broad-spectrum antibacterial activity. Therefore, a...
Pseudomonas species are mainly associated with spoilage of dairy products due to their proteolytic activity . Therefore, the goal present study was isolate pseudomonas spp and then identify virulence factors that have a bad impact on milk qulity One hundred samples from ( raw ,Karish cheese , youghrt Ice cream) divided 25 each one were collected examined found using PCR technique ps. aeuroginosa in 20 ,16 ,8 8 %in karish ,youghrt ice cream respectively while ,ps. Fluorescence 28, 20,12 8%...
Milk preservation is closely related with its microbiological quality. The spoilage may occur at any stages from production till consumption and during milk processing. Many potent antimicrobials discovered recently but, it important to test their efficacy against undesirable bacteria inside the food materials that help improve safety validity. Our research was focused on comparative antibacterial activities between chitosan, lysozyme different mixtures bacterial strains by agar well...
This research investigated the antioxidant activities and quality characteristics of functional yogurt supplemented with naturally derived protein, specifically lysozyme (LZ), as well its thermally modified variants PLZ treated at 63°C for 30 minutes (hold type pasteurization method) BLZ 100°C 10 (using boiling temperature). Among these variants, best capacity was reported PLZ, followed by LZ. Subsequently, different samples (YCtrl, YLZ, YPLZ, YBLZ) were prepared. Through weekly assessments,...
Background and Aim: Artemisia annua (AA), used as a growth promoter in poultry, lowers feed costs enhances economic efficiency. This study aimed to assess the impact of varying AA concentrations on broiler chicken growth, gene expression, profitability. Materials Methods: Two hundred 1-day-old male Cobb chicks were randomly allocated into four treatment groups, each containing five replicates 10 birds. The experimental groups consisted G1 (basal diet), G2 diet with 0.3% AA), G3 0.6% G4 0.9%...
Abstract Pseudomonas spp are considered the most common milk-associated psychotropic bacteria, leading to milk deterioration during storage so, our study aimed growth behavior of aeruginosa in after employing chitosan nanoparticles (CsNP 50, 25 and15 mg/100ml) and selenium (SeNP 0.5, 0.3 0.1mg/100ml) as a trial control bacterial five days cooling storage. Our relies on using ion gelation method green synthesis for conversion nanosized particles, respectively, we subsequently confirmed their...
Abstract Fasciola gigantica is one of the worldwide parasites that cause livestock and human illnesses. Chemotherapy now primary therapeutic option for its treatment. Drug abuse has led to emergence drug-resistant strains. As a result, there an urgent need discover natural efficient anthelmintics against spp. The study aims evaluate ovicidal activities camel milk fractions on F. eggs. In in vitro assay eggs were submitted different concentrations (0.5% 1%) fractions; Camel Milk Whey (CMW),...
Abstract Food-borne illnesses and microbial food contamination are crucial concerns still issues of major worldwide concern. Lysozyme (Lz) is an active protein against Gram-positive bacteria through its muramidase lytic activity, however, several authors could identify some antimicrobial peptides derived from native Lz that have exaggerated broad-spectrum antibacterial activity. Therefore, a lysozyme preparation (LzP) developed in order to broaden the spectrum. In this work, we investigated...
