Salmonella enterica is one of the most common causes foodborne illness worldwide. Contaminated poultry products, especially meat and eggs are main sources human salmonellosis. Thus, aim present study was to determine prevalence, antimicrobial resistance profiles, virulence, genes Enteritidis (S. enteritidis) Typhimurium Typhimurium) isolated from laying hens, table eggs, humans, in Sharkia Governorate, Egypt. The activity Biosynthesized Silver Nanoparticles (AgNPs) also evaluated. spp. were...
Listeria monocytogenes (L. monocytogenes) is a foodborne pathogen that poses significant risks to public health and food safety. The present study aimed identify the presence of spp. in various samples, including pasteurized milk, chicken fillets, stool samples from pregnant women Sharkia Governorate, Egypt. Additionally, identified serotypes, virulence-associated genes, antimicrobial resistance patterns, biofilm formation L. isolates. Moreover, antibacterial anti-biofilm activity...
The objective of the present study was to estimate seroprevalence Brucella spp. in humans and cattle at Sharkia Governorate, Egypt. In addition, identification milk samples by PCR culture with evaluation risk factors associated were carried out. Overall, antibodies examined 23.8%, while human participants it 21%. examination 205 using revealed that 6.3% positive for B. abortus biovar 1 results confirmed methods. Multivariate logistic regression consumption unpasteurized dairy products,...
Aflatoxins (AFs) are toxic and carcinogenic metabolites produced by a variety of fungi. Aflatoxin M1 (AFM1) is the major type frequently found in milk dairy products, thus posing significant impact on human health. The current study was undertaken to examine some products for contamination with AFM1 local markets, Sharkia Governorate, Egypt, as well effect manufacture. A total 75 samples (15, each) raw milk, pasteurized yoghurt, processed cheese Domiati were randomly collected. detected 27...
Background: Bacillus cereus and Yersinia enterocolitica are implicated in foodborne diseases (FBD) which have major effects on human health, therefore it is considered as universal public-health disorders. Essential oils essential Nano emulsions a sufficient antibacterial performance against variety of bacteria especially multi-drug resistant bacteria. Probiotics showed several health benefits via moderating the GIT microbiota their metabolites. Aim: The study was designed for evaluating...
Residual content of lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) in the retailed meat dairy products Egypt was estimated. Calculation estimated weekly intake (EWI) health risks followed. Results revealed detection tested metals all samples at variable concentrations with higher Pb Cd than maximum permissible limits. However, calculated EWI did not exceed provisional tolerable established by World Health Organization. Furthermore, calculation hazard ratio index for mixed metal...
Background: Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus) are well defined as food poisoning pathogens which highly resistant need continuous studies. Aim: The purpose of the work was to examine phenotypic genotypic characters both P. S. aureus, treatment trial with medicinal plant. Methods: Samples were examined for isolation on selective media followed by biochemical confirmation, biofilm formation, genes detection, expression pslA gene performed qRT-PCR...
Breast milk is considered the best food for infants, however in some cases infant must stay away from his mother and be supplied with milk by other means. In this case we have choice between expressed breast rehydrated formula so, applied work to assess microbiological status of both. The findings achieved our study revealed that 27 (54%) out examined samples were contaminated different microbes a mean count 6.8×10 3 ± 2×10 2 CFU/ml. samples, 78% an average 3.3×10 5 CFU/ml. Stapylococcus...
This study was carried out during the period from February 2016 to 2017 on 100 Friesian dairy cows aged (3-7 years old) of different parities belonged private farm which locate at Hehia city Sharkiya governorate. The aim present investigate effect age their ingestive behaviour, suckling disorders, productive performance, milk constituents and serum cortisol level cows. results were revealed that, 4th old highest significant (P
A C TDairy products such as raw milk, Kariesh cheese, and yoghurt are considered is health food that supports part of the human needs protein, minerals, vitamins.This study was taken to investigate mold contamination in retailed Zagazig city, Egypt.In addition, isolation identification different genera were further conducted.Besides, total aflatoxins (AFTs) estimated examined samples, their daily intakes risk assessment calculated.An experimental trial conducted antifungal activities three...
Cheese is regarded as an essential dairy product that cover part of the human needs with vitamins and minerals.However, cheese also implicated in many food poisonings outbreaks worldwide.This study conducted to estimate coliforms E. coli, investigate occurrence shigatoxigenic coli four types mostly consumed Zagazig city, Egypt.In addition, detection coding genes for shiga toxins (stx1, stx2) was further screened using PCR.Besides, antimicrobial susceptibility isolated examined.The obtained...
Cheese is considered as a healthy and complete nutrient that supports part of the human needs with protein, minerals, vitamins.This study was conducted to examine mold growth in four cheese types including Kariesh, Feta, Domiati, Rumy retailed Zagazig city, Egypt.In addition, isolation identification different genera further screened.Furthermore, proteolytic lipolytic abilities identified molds were screened.Rumy samples followed by Kariesh showed highest total count.The prevalent...
