G protein-coupled receptors (GPCRs) are one of the largest families of proteins, and here we scan the recently sequenced chicken genome for GPCRs. We use a homology-based approach, utilizing comparisons with all human GPCRs, to detect and verify chicken GPCRs from translated genomic alignments and Genscan predictions. We present 557 manually curated sequences for GPCRs from the chicken genome, ...

The genotypes and oxacillin resistance of 263 Staphylococcus aureus isolates cultured from chicken cloacae (n = 138) and chicken meat (n = 125) was analyzed. Fifteen spa types were determined in the studied S. aureus population. Among 5 staphylococcal protein A gene (spa) types detected in S. aureus from chicken, t002, t3478, and t13620 were the most frequent. Staphylococcus aureus isolates fro...

abstract: the extreme polymorphism in mhc b-f genes enables the chickens to recognize enormous numbers of foreign peptides to trigger an immune reaction. study of this genetic resources is very important and it is essential to avoid the loss of genetic variability. genetic polymorphism among arian strain, a endogenous broiler chickens in iran, was investigated. in this study pcr-sscp was carrie...

A 150-kb DNA fragment, which contains the gene of the chicken complement regulatory protein CREM (formerly named Cremp), was isolated from a microchromosome by screening bacterial artificial chromosome library. Within 100 kb of the cloned region, three complete genes encoding short consensus repeats (SCRs, motifs with tandemly arranged 60 aa) were identified by exon-trap method and 3'- or 5'-RA...

An in vitro bioassay for mammalian thyroid stimulating hormone (TSH) based on TSH-induced cyclic adenosine 3',5'-monophosphate (cAMP) production in FRTL-5 cells, a rat thyroid cell line, was used to measure chicken TSH. The addition of chicken pituitary homogenate equivalent to > or = 25% of a chicken pituitary gland to cultured FRTL-5 cells increased cAMP within these cells in a dose-dependent...

DNA isolated from avian virus-producing leukemic myeloblasts induced the production of viruses, but not morphological transformation, in cultivated chicken fibroblasts. The recovered virus had the same biological characteristics as the original avian myeloblastosis virus (AMV) and produced myeloblastosis and nephroblastomas when injected into chickens. Neutralization experiments with chicken an...

ABSTRACT- Today, the authenticity of meat products with less costly and desirable species has increased. Therefore and considering religious, economicalor public health concerns, proper actions should be taken to prevent such frauds. In this study, real time PCR assay was applied for rapid, sensitive and specific identification and quantification of chicken tissue in meat products. Specific pri...

Chicken breast and beef loin were ground, and no, NaCl, NaCl+myoglobin, NaCl+Fe(II), or NaCl+Fe(III) additions were made; patties were then prepared. Half of the patties were packaged in oxygen-permeable bags and stored at 4 degrees C for 10 days, and the other half were cooked in a 95 degrees C water bath to an internal temperature of 75 degrees C, packaged in oxygen-permeable zipper bags, and...
