The Galβ1-4Gal epitope is rarely found in mammals, and the natural antibody against Galβ1-4Gal is rich in human. In contrast, we have previously demonstrated the presence of Galβ1-4Gal in pigeon and ostrich, and the absence of this epitope in chicken. Here, to further investigate the expression of this glycan among birds, egg white glycoproteins and egg yolk IgG from nine species of birds, name...

We report the draft genome sequence of Lactobacillus ingluviei strain Autruche 4 (CSURP209) isolated from an ostrich. L. ingluviei is associated with weight gain in mice. This genome sequence may help us understand the obesity-induced mechanisms of intestinal bacteria.

Ostrich raising around the world have some key factors and farming profit depend largely on information and ability of farmers to rear these animals. Non fertilized eggs from ostriches are discharged in the reproduction season. Staphylococcus aureus and Escherichia coli are microorganisms involved in animal and human diseases. In order to optimize the use of sub products of ostrich raising, non...

The ultrastructure of the eggshell of the domestic hen has been well researched and structural studies of other avian species, such as the ostrich, often base their interpretation of egg shell structure on that of the chicken. In the ostrich, lowered hatchability and hatching trauma may be due to shell ultrastructural abnormalities. In the present study the ultrastructure of the calcified porti...

The ostrich is an important animal in many livestock industries and, in the developing world, the export of meat and skins is a valuable source of foreign currency. As the successful growth and reproductive performance of ostriches depends on good nutrition it is extremely important to provide the correct diet. Some researchers have incorrectly assumed that poultry diets are useful for ostriche...

Two experiments were performed to study Phe imbalance and toxicity in 1-wk-old Babcock B380 chicks resulting from the addition of either a mixture of indispensable amino acids lacking Phe (IAA - Phe) or excess Phe to a diet that was nutritionally adequate in Phe. Chicks received a preexperimental semipurified diet for 1 wk and experimental diets from 7 to 14 d of age. In the first experiment, t...

An experimental infection of mice was performed in order to investigate the potential for interspecies transmission in mammals of Italian HPAI viruses of the H7N1 subtype. Three avian origin isolates were selected, two strains obtained from ostrich (one of which contained a PB2-627 Lysine residue) and one from a chicken. Following intranasal infection of mice, clinical signs and mortality were ...

Aspergillosis is an important infectious disease in ostriches that can be acute or chronic. Because of high morbidity and mortality rate of aspergillosis in ostriches, it can cause serious financial losses to the ostrich production industry. In this study, we discuss some outbreaks of Aspergillus infection in ostrich farms of eastern regions of Iran during 2010-2012. Signs of respiratory involv...

The effects of odor exposure during the last 2 days of incubation and immediately after hatching on subsequent responses by chicks to that same scent were assessed. When tested with an orange-treated and an unscented container, chicks that had been previously exposed to orange odor more rapidly approached both containers than did control chicks and spent more time near them. In both conditions,...

Climate change is causing more frequent and intense storms, and climate models predict this trend will continue, potentially affecting wildlife populations. Since 1960 the number of days with >20 mm of rain increased near Punta Tombo, Argentina. Between 1983 and 2010 we followed 3496 known-age Magellanic penguin (Spheniscus magellanicus) chicks at Punta Tombo to determine how weather impacted t...
