The bacterial eggshell contamination of shell eggs in different commercial housing systems; two conventional cages, one organic aviary system and one barn production, were compared. The total counts of aerobic bacteria and the total counts of Gramnegative bacteria on the shell were used to detect key points where contamination occurred and to study the progress of contamination in the egg handl...

Possibilities of predicting eggshell ultrastructure from direct non-destructive and destructive measurements were examined using 120 Fayoumi eggs collected from the flock at 45 weeks of age. The non-destructive measurements included weight, length and width of the egg. The destructive measurements were breaking strength and shell thickness. The eggshell ultrastructure traits involved the total ...

This experiment studied the effect of four calcium (3.0, 3.5, 4.0, and 4.5%) and four available phosphorus levels (0.25, 0.30, 0.35, and 0.40%) in the diet of semi-heavy commercial layers after molting. Hisex Brown layers between 90 and 108 weeks of age were distributed in a completely randomized experimental design with a 4x4 factorial arrangement with 16 treatments of five replicates of eight...

Methylene blue staining method was used to distinguish O. viverrini eggs from Haplorchis taichui and Prosthodendrium molenkampi eggs. All eggs were obtained from dissected adult worms, fixed in 10% formalin, and stained with methylene blue prior to light microscopy observation. The distinct musk-melon-like texture of the O. viverini eggshell surface and the thread-like texture of H. taichui egg...

Background: Peripheral nerves may be damaged during an injury and its current standard treatment is using an autologous nerve. Objectives: The purpose of this experimental study is to evaluate and compare the histological results of nerve regeneration after using the eggshell membrane (ESM) guidance channel with autograft. Materials and Methods: Thirty adult male rats were divided into th...

BACKGROUND AND OBJECTIVES To evaluate the effect of eggshell membrane (ESM) patching for tympanic membrane (TM) perforation, and to investigate correlations between healing time and age, gender, patching time, perforation size, and perforation location. SUBJECTS AND METHODS One hundred and seventy-five patients diagnosed with traumatic TM perforation at the Department of Otorhinolaryngology-H...

The organic matrix from normal and pimpled calcified chicken eggshells were dissociated into acid-insoluble, water-insoluble, and facultative-soluble (both acid- and water-soluble) components, to understand the influence of shell matrix on eggshell qualities. A linear correlation was shown among these 3 matrix components in normal eggshells but was not observed in pimpled eggshells. In pimpled ...
