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...

the determination of toxoplasma gondii prevalence in a variety of domestic birds is thought as a good indicator of distribution of t.gondii ooccyts in the environment. to verify the potential role of domestic birds in circulating toxoplasmosis in iran, the present study was conducted in mazandaran provinces, northern iran. latex agglutination test (la) antibodies were found in 25 of 58 free-ran...

Assessment of ventricular morphology using echocardiography in Ornate tinamous (Nothoprocta ornata) and domestic chickens (Gallus domesticus)

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...

Chromosome painting probes specific for macrochromosomes 1, 2, 3, 4, 5, and Z were applied to both mitotic and lampbrush chromosomes of the chicken (Gallus gallus domesticus). Five autosomal macrobivalents and sex chromosomeZ in the lampbrush phasewere identified and their correspondence to the target chromosomes in the metaphase of mitosis was shown. Nascent transcripts on lateral loops of the...

A study was undertaken to determine the longevity of active muscarinic receptors on abattoir-sourced isolated ileum preparations from Gallus gallus domesticus, with a view to using the tissue as an experimental tool for functional response assays in laboratory experiments. A concentration-response curve for acetylcholine (1-256 μM) was plotted, in the presence and absence of 1, 3 and 6 nM atrop...
