Proteins are essential constituents of all organisms; both egg white proteins and egg yolk are source of protein. The aim of this study was conducted to perform preliminary studies to analyses and compare egg white proteins and yolk proteins from different avian species (guineafowl, dwarf hens, local hen, Shami, turkey, duck, geese, partridge and quail) via or with SDS-PAGE (Sodium Dodecyl Sulfate–Polyacrylamide Gel Electrophoresis ). 18 Fresh eggs of different poultry species (guineafowl, dwarf hens, local hen, Shami, turkey, duck, geese, partridge and quail) were collected from various farms in the Sulaimani province. Data on egg proteins were analyzed using Statistical Xlstate used for dendrogram construction and PCA. The main egg white proteins were Ovomicin, Ovotransferrin, Ovalbumin, Flavoprotein, α- chymotrypsinogen, and Trypsin inhibitor. The main lipoproteins were Apovitellenin VI, Apovitellenin Vb, Apovitellenin V, Apovitellenin IIIa, Apovitellenin III, Apovitellin 7, B-Livetin, Apovitellenin IIa, Apovitellenin II, and Apovitellenin I. All these lipoproteins were observed in the nine birds species. The egg white proteins and yolk lipoproteins for nine species were examined. It can be concluded the large differences were found in a mount of egg white proteins and yolk lipoproteins of the nine species of birds.

Quantitative Changes

Water-soluble proteins, mainly livetins (α-, β-, γ-), are present in hen egg yolk (Martin, Vandegaer & Cook, 1957). They represent 5% of fresh yolk solids (Saito, Martin & Cook, 1965). During the later stages of incubation the watersoluble proteins (water-soluble fraction, WSF) undergo a marked increase in relative proportion; after 15 days of incubation they form over 15% and at 18 days over 40% of yolk-residual solids (Saito et al. 1965). This proportional increase of the WSF is tentatively explained by the passage of egg-white proteins into yolk (Mclndoe, 1960; Saito et al. 1965). Indeed some egg-white proteins (ovalbumin, conalbumin and lysozyme) have been found in the yolk from 14 to 15 days of incubation (Saito & Martin, 1966; Carinci, Wegelin & Manzoli-Guidotti, 1966). At these stages ovalbumin is present in the yolk in such a great quantity that it is difficult to detect qualitative and quantitative changes of other proteins without resorting to further fractionations.

Aim: to study the association of food and inhalation sensitization with the severity of atopic dermatitis (AtD) in order to improve its treatment and prevention methods. Patients and Methods: the study included 50 patients with AtD from 2 to 44 years old. The study included clinical and laboratory research methods. The survey analyzed the history and anamnesis vitae, estimated the age at the AtD onset, determined the nature of concomitant pathology, the possible causes of cutaneous exacerbation, the allergic severity in the family history, the severity score on the SCORAD (Scoring of Atopic Dermatitis) scale and the efficacy of previous therapy. The immunological examination consisted of the quantitative determination of specific IgE and IgG antibodies in the blood serum to inhaled and food allergens by immunochemiluminescence assay on an IMMULITE 2000 XPi analyzer. Results: according to the detection frequency of IgE to food allergens in patients with AtD: the leading positions were taken by the chicken egg (egg white in 26% of cases, egg yolk in 20%); IgE to banana was detected in 17% of cases; in 12% — to cow’s milk, more common — to the β-lactoglobulin fraction. When studying the activity of inhaled allergens, respiratory sensitization to the cat epithelium was detected in 26% of cases, and to black birch — in 24%. Hypersensitivity to herbs (wormwood, herbal mixture) and house dust allergens (8%, respectively) was found much less common. In severe AtD, IgE to respiratory allergens prevailed: at n=38, the IgE concentration to cat epithelium and black birch was 12.4±1.4 IU/mL each. Besides, there was a significant sensitization to food allergens, namely, the IgE concentration to egg white — 5.4±0.9 IU/mL. Conclusion: the study revealed the sensitization of patients with AtD to food (mainly egg white, egg yolk, banana and cow’s milk) and respiratory (mainly cat epithelium, black birch) allergens. Determination of the IgE concentration in the blood serum of patients showed that there was a significant concentration increase to egg white, cat and black birch in severe AtD. Therefore, it is advisable to test for specific allergens in all patients with moderate to severe AtD.

Whole Egg

As part of a whole egg, egg white proteins are embedded in a lipid matrix that could modify their presentation to the immune system and their allergenic properties. The present study examines the impact of the main egg lipid components, triacylglycerides and phospholipids, in the early events of sensitization to egg. To this end, BALB/c mice were exposed intragastrically to egg lipids and egg lipid fractions, alone and in mixtures with egg white proteins, and Th2-promoting and proinflammatory effects were investigated. Our results highlight that the egg lipid fraction is responsible for Th2 adjuvant effects and point at a different influence of triacylglycerides and phospholipids on the bioavailability and immunomodulating properties of egg white proteins. While triacylglycerides promote type 2 responses at the small intestine level, phospholipids reduce the solubility of EW proteins and induce Th2 skewing in lymphoid intestinal tissues, which may have a direct impact on the development of egg allergy.

The present paper describes a simple and efficient electrophoretic method to identify the species provenience of edible eggs in food products. The proteic pattern of egg yolk and egg white was described using polyacryl amide gel electrophoresis under denaturating conditions (PAGE-SDS) separately for the egg yolk and for the egg white proteins from five edible egg species, as follows: hen, goose, duck, turkey and quail. The molecular weight of each protein strip was calculated using a molecular weight standard curve. Separately, an electrophoretic protein pattern of all the mentioned samples was done using polyacryl amide gel electrophoresis under undenaturating conditions (native PAGE). The results show clearly distinct patterns in electrophoregrams resulted both in denaturating and undenaturating conditions for each species. These methods could be useful tools for egg species routine identification in various food industrial mixtures.

Egg White Proteins

The aim of the present study was to evaluate and to compare the physicochemical composition of egg white, and to characterize and estimate the quantitative variations of egg white proteins of different birds’ species (duck, quail, Chicken, partridge and goose). For each bird species, the whole egg temperature, weight, height, density and shape index were evaluated. After breaking the eggs, a visual examination was performed then vitelline (VI) and albumen (AI) indexes and the haugh unit (HU) were measured. The study of the quality and the characterization of egg white proteins were performed by Agarose Gel Electrophoresis. The total egg weight varied within a range of (8.98±0.82 g to 142.91±10.34 g) for quail and goose, respectively. The thickness of the egg yolk was almost three times higher than that of the egg white in all breeds. The egg freshness, measured by HU, was higher in partridge, followed by quail and chicken breeds with values of 88.81±0.09, 87.45±3.33, 81.53±2.16, respectively. The VI shows values of about 0.40. The egg yolk/ white ratio ranged from 47 and the pH varied from 8.37 to 8.95 for all local species studied. The egg white protein content was higher for all species (up to 14.45g/100 g). Three types of proteins are identified by agarose gel electrophoresis (ovalhibitor, ovotransferrin and ovalbumin) with a quantitative difference between bird species. Densitometric analysis shows a qualitative difference due to the presence of type C lysozyme in chicken egg white.
