TL;DR: There are indications that SE survives the attacks with the help of antimicrobial molecules during the formation of the egg in the hen's oviduct and inside the egg, which appears to require a unique combination of genes encoding for improved cell wall protection and repairing cellular and molecular damage, among others.
Abstract: Salmonella Enteritidis (SE) has been the major cause of the food-borne salmonellosis pandemic in humans over the last 20 years, during which contaminated hen's eggs were the most important vehicle of the infection. Eggs can be contaminated on the outer shell surface and internally. Internal contamination can be the result of penetration through the eggshell or by direct contamination of egg contents before oviposition, originating from infection of the reproductive organs. Once inside the egg, the bacteria need to cope with antimicrobial factors in the albumen and vitelline membrane before migration to the yolk can occur. It would seem that serotype Enteritidis has intrinsic characteristics that allow an epidemiological association with hen eggs that are still undefined. There are indications that SE survives the attacks with the help of antimicrobial molecules during the formation of the egg in the hen's oviduct and inside the egg. This appears to require a unique combination of genes encoding for improved cell wall protection and repairing cellular and molecular damage, among others.

TL;DR: Utilization of eggshell as a catalyst for biodiesel production not only provides a cost-effective and environmental friendly way of recycling this solid eggshell waste, significantly reducing its environmental effects, but also reduces the price of biodiesel to make biodiesel competitive with petroleum diesel.

TL;DR: Under the characterization measurements investigated, it was found that the pore structures of the two biomaterials belong to a typical Type II, indicating that they should be basically characteristic of nonporous materials or materials with macropores or open voids.

TL;DR: Catastrophic declines of three raptorial species in the United States have been accompanied by decreases in eggshell thickness that began in 1947 and amounted to 19 percent or more, and were identical to phenomena reported in Britain.
Abstract: Catastrophic declines of three raptorial species in the United States have been accompanied by decreases in eggshell thickness that began in 1947, have amounted to 19 percent or more, and were identical to phenomena reported in Britain. In 1967, shell thickness in herring gull eggs from five states decreased with increases in chlorinated hydrocarbon residues.

TL;DR: Egg size increased with increasing age of the hen, although more for the ISA-White hens than theISA-Brown hens, and the yolk increased more in size than did the shell and albumen, and during storage, albumen weight decreased and yolk weight increased slightly.
