2018 | الكلمات المفتاحية Embryo lethality assay, Congo red, Haemolysin, Motility, Pathogenic E. coli,
An alternative approach for evaluating the phenotypic virulence factors of pathogenic Escherichia coli
Escherichia coli is a recognized zoonotic food-borne pathogen; however, the use of polymerase chain reaction (PCR) in the underdeveloped countries to differentiate pathogenic from non-pathogenic E. coli is a problematic issue. Our grail was to assess the phenotypic virulence markers motility, hemolysin, congo red agar, embryo lethality assay and serum resistance for pathogenic E. coli (PEC) correlated to PCR tests ... إقراء المزيد

2017 | الكلمات المفتاحية PCR, ETEC, E. coli, Cheese, Milk,
Molecular Detection of Enterotoxigenic E. coli in raw Milk and Milk Products
This study aimed to determine the incidence of E. coli in raw milk and cheese, in addition to isolate and identify Enterotoxigenic E. coli. The existence of heat stable toxin (STh) and heat labile toxin (LT) genes were determined in the isolated strains. This study included 350 samples of raw milk and cheese samples. Different media were used to isolate ... إقراء المزيد

2016 | الكلمات المفتاحية antibiotic resistance genes, resistance in the quinolone, chicken,
Prevalence of the antibiotic resistance genes in coagulase-positive and negative-Staphylococcus in chicken meat retailed to consumers
The use of antibiotics in farm management (growing crops and raising animals) has become a major area of concern. Its implications is the consequent emergence of antibiotic resistant bacteria (ARB) and accordingly their access into the human food chain with passage of antibiotic resistance genes (ARG) to the normal human intestinal microbiota and hence to other pathogenic bacteria causative human ... إقراء المزيد

2016 | الكلمات المفتاحية Listeria species, Buffalo, Cow, Virulence genes, Biofilm formation, Antibiotic resistance,
Determination of virulence and antibiotic resistance pattern of biofilm producing Listeria species isolated from retail raw milk.
Background: One of the foodborne pathogens is Listeria monocytogenes, which causes serious invasive illness in elderly and immunocompromised patients, pregnant women, newborns and infants ranking second after salmonellosis because of its high case fatality rate. Listerial cow mastitis marked by abnormal milk, increased cell counts and reduced production has not been reported. Therefore, apparently healthy cows can be reservoirs of ... إقراء المزيد

2016 | الكلمات المفتاحية Salmonella enterica, Complete Genome Sequences, Retail Ground Turkey,
Complete Genome Sequences of  Salmonella enterica Serovars Anatum and  Anatum var.15+, Isolated from Retail Ground Turkey.
The complete genome sequences of two isolates of Salmonella enterica serovars Anatum and Anatum var. 15 revealed the presence of two plasmids of 112 kb and 3 kb in size in each. The chromosome of Salmonella Anatum (4.83 Mb) was slightly smaller than that of Salmonella Anatum var. 15+ (4.88 Mb). إقراء المزيد

Whole-Genome Sequencing of Salmonella enterica subsp. enterica Serovar Ouakam Isolated from Ground Turkey
In this report, we announce the first whole-genome sequencing of Salmonella enterica subsp. enterica serovar Ouakam strain GNT-01, isolated from ground turkey retail meat. The strain has a chromosome of 5,088,451 bp long, with a G+C content of 52.3%, and a plasmid of 109,715 bp. إقراء المزيد

2016 | الكلمات المفتاحية Mycoplasma bovis; gapA gene, p40 pseudogene; uvrc gene, adhesion.,
Sequence analysis of three genes of Mycoplasma bovis isolated from Egyptian cattle and buffaloes
The present study concerned with phylogentic analysis of three genes (gapA, p 40 pseudogene and uvrC) related to adhesion and virulence of Mycoplasma bovis (M. bovis) in cows and buffaloes. In this study, 625 milk samples were collected from clinical and subclinical mastitis in cows and buffaloes in two Egyptian Governorates Fayoum (south of Cairo Governorate) and Dakahlia (south of ... إقراء المزيد

2015 | الكلمات المفتاحية PCR, Contamination, Tissue Culture, Mycoplasma,
One of the main problems in cell culture unit is mycoplasma contamination. It can extensively affect cell physiology and metabolism. As the applications of cell culture increase in research, industrial production, cell therapy and its importance for diagnostic routine work in selected labs, so more concerns about mycoplasma contamination will arise. In our study, a total of 50 cell cultures ... إقراء المزيد

2015 | الكلمات المفتاحية Sohag, Poultry feed, Contamination, Pathogenic fungi,
The investigation of pathogenic fungi in poultry feed in some selected poultry farms in Sohag Governorate, Egypt
Mould occurrence and growth in poultry farms is one of the major threats to poultry economy and health. The aim of this study was to investigate the mycological contamination of poultry feeds used in poultry farms in Sohag Governorate, Egypt. A total of 160 samples of poultry feed were collected from 10 farms for mycological analysis. The isolated fungi from ... إقراء المزيد
