With the aim of elucidating in greater detail the genealogical origin of the present domestic fowls of the world, we have determined mtDNA sequences of the D-loop regions for a total of 21 birds, of which 12 samples belong to red junglefowl (Gallus gallus) comprising three subspecies (six Gallus gallus gallus, three Gallus gallus spadiceus, and three Gallus gallus bankiva) and nine represent di...

Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...

an adult native cock (gallus gallus domesticus) referred to the aviary clinic with multiple different sizes of round dermal nodules. the bird died few days later, and was then submitted for further evaluation. macroscopic and microscopic examinations as well as a pcr test were done to identify type and cause of the tumor. in histopathological assessment of biopsy specimen, it consisted of inter...

The EAV-HP group of chicken endogenous retrovirus elements was previously shown to be defective, with large deletions of the pol gene. In this report, we demonstrate that genomes of other Gallus species also maintain EAV-HP elements with similar deletions. The chicken EAV-HP1 locus was detected in both red (Gallus gallus gallus) and Sonnerat's (Gallus sonneratii) jungle fowl with identical inte...

To research effects of the artificial selection of Gallus gallus on G. domesticus' nucleotide diversity of immune genes, sequence polymorphisms of G. domesticus (23 genes), G. gallus (23 genes), G. lafayetti (17 genes), and G. sonneratii (17 genes) were obtained from GenBank. The data set included 819 polymorphisms. Immune gene polymorphism and selection efficiency in the data from those four s...

Domesticated chickens (Gallus gallus domesticus) are a dominant part of the global human diet. Although early domestication history this species remains disputed, Mainland Southeast Asia (MSEA) is assumed to have been initial center. The eastward spread into Island (ISEA) and Pacific typically attributed human-mediated dispersals. Chicken relatively common at Neolithic sites but extremely rare ...

In the European Union (EU), targets are being set for the reduction of certain zoonotic Salmonella serovars in different animal populations, including poultry populations, within the framework of Regulation (EC) No. 2160/2003 on the control of zoonoses. For a three-year transitional period, the EU targets were to cover only Salmonella Enteritidis and S. Typhimurium (and in addition S. Hadar, S....

Ambient-pressure soft X-ray photoabsorption spectroscopy (XAS) was demonstrated to be applicable to the chemical analysis of hydrated transition-metal compounds. For this purpose, even under ambient-pressure conditions, electron yield detection XAS (EY-XAS), based on a simple drain-current set-up, was used to overcome a weakness in fluorescence yield detection XAS (FY-XAS), which does not give ...
