Myoglobin has an important physiological role in vertebrates, and as the primary sarcoplasmic pigment in meat, influences quality perception and consumer acceptability. In this study, the amino acid sequences of Japanese quail and northern bobwhite myoglobin were deduced by cDNA cloning of the coding sequence from mRNA. Japanese quail myoglobin was isolated from quail cardiac muscles, purified ...

The common quail (Coturnix coturnix) is a popular game species for which restocking with farm-reared individuals is a common practice. In some areas, the number of released quails greatly surpasses the number of wild breeding common quail. However, common quail are difficult to raise in captivity and this casts suspicion about a possible hybrid origin of the farmed individuals from crosses with...

AIM An attempt has been made to study the Myxovirus resistant (Mx1) gene polymorphism in Japanese quail. MATERIALS AND METHODS In the present, investigation four fragments viz. Fragment I of 185 bp (Exon 3 region), Fragment II of 148 bp (Exon 5 region), Fragment III of 161 bp (Exon 7 region), and Fragment IV of 176 bp (Exon 13 region) of Mx1 gene were amplified and screened for polymorphism b...

Thirteen oncogenic and necrotizing animal viruses were assayed in LIFE Sciences, Inc. (LSI)-specific pathogen-free Japanese quail and LSI-specific pathogen-free chicken embryo cell cultures. Nine viruses produced similar titers in the quail and chicken cell systems, whereas four viruses showed significantly higher titers in chickens. Young Japanese quail and chickens were inoculated with five s...

Chromosome homology is highly conserved between chicken (Gallus gallus) and Japanese quail (Coturnix japonica) and a few chromosome rearrangements occurred in the evolution of these two species. Microsatellite markers are invaluable tools in molecular biology for genome analysis, mapping, search for quantitative trait loci, and phylogenetic studies. In the current study, 25 microsatellite seque...

The effect of environmental conditions on hatching indices of poultry eggs is sufficiently important that new methods for their improvement are sought, among others through exposing the eggs during hatching to an artificially generated magnetic field of variable frequency. Hatching eggs in this study came from Pharaoh quail in the 4th month of laying. The flock was kept under optimum microclima...

We have shown previously that: (1) female Japanese quail, Coturnix japonica, increase and male Japanese quail decrease their tendencies to affiliate with potential sex partners after seeing them mate, and (2) in both sexes of quail, affiliative preferences and choice of a sex partner are highly correlated. Here we predict that because effects of a prior male's sperm on a second male's probabili...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes a...
