egg drop syndrome (eds) is caused by a hemagglutinating adenovirus which has become a major cause of lost egg production and sever economic losses in breeder and layer chicken flocks throughout the world. a pcr assay was optimized for detection of eds virus in inoculated allantoic fluids (afs) of duck and chicken emberyonated eggs. two strains of eds viruses were propagated in allantoic cavity ...

Transplantation of tumor xenografts to fertilized chicken eggs is a promising animal replacement method, which has successfully been used for xenotransplantation of pancreatic ductal adenocarcinoma (PDA) cells. PDA is characterized by a pronounced tumor hypoxia, which mediates aggressive growth, therapy resistance and cancer stem cell (CSC) features. For in vivo experimental evaluation of hypox...

BACKGROUND Hen's egg allergy ranks among the most frequent primary food allergies in children. We aimed to investigate sensitization profiles of egg allergic patients and compare in vitro IgE reactivities of eggs from ancient chicken breeds (Araucana and Maran) with those from conventional laying hen hybrids. METHODOLOGY Egg allergic children (n = 25) were subjected to skin prick test, double...

Salmonella enterica serovar Enteritidis (SE)-induced diarrhea in humans is the typical non-typhoid diarrhea. It develops acutely or subacutely and may be fatal. This SE infectious disease suddenly became a major public health issue worldwide in the 1980s. The main causative food material of SE food poisoning is chicken eggs, and many outbreaks of food poisoning caused by chicken eggs occurred t...

We examined the characteristics of food allergy prevalence and suggested the basis of dietary guidelines for patients with food allergies and atopic dermatitis. A total of 2,417 patients were enrolled in this study. Each subject underwent a skin prick test as well as serum immunoglobulin E (IgE) measurement. A double-blind, placebo-controlled food challenge was conducted using milk, eggs, wheat...

Introduction: Feathers are important body structures that act as surface insulators to reduce maintenance energy requirements and also to protect skin against abrasions and infection. The purpose of this study is to investigate the effects of methionine injection into the yolk sac on development of feather follicle in chicken embryo. Methods: 50 fertilized eggs (weighting 50±0.4 gr) of Ross×...

OBJECTIVE To determine the antimicrobial resistance profile of Escherichia coli (E coli) isolated from the shell membrane and yolk of commercial chicken eggs in Grenada. METHODS A total of 450 eggs were collected from different locations including small (33.3%) and big farms (26.7%), roadside vendors (26.7%) and supermarkets (13.3%). The shell membranes and yolk were cultured separately on bl...

Chicken eggs are one of the most important foods in the human diet all over the world, and the demand for eggs from free range hens has steadily increased. Congener-specific analyses of 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were performed on 6 free range and 12 caged chicken egg samples collected in Taiwan. The mean level of PCDD/Fs in the free range egg samples was 5...

Due to concern about increasing mortality among 7 -day old chicks in a chicken hatchery the management arranged to screen all hatchery staff for salmonella excretion. The hatchery is part of a complex involving all stages of chicken meat production but is physically separate from the broiler units and chicken processing plant. The hatchery also has its own staff, there being no exchange of staf...
