The major histocompatibility complex (Mhc) of the ring-necked pheasant contains two polymorphic Mhc class II B genes. We show here, by screening of a cDNA library and RT-PCR from RNA, that both of these loci, Phco-DAB1 and Phco-DAB2, normally are transcribed in the spleen. They differ mainly in the 3' untranslated (UT) region, with the transcript lengths, not including the poly(A) tails, being ...

listeria monocytogenes can be found throughout the environment and in many foods. it is associated primarily with meat and animal products. listeria monocytogenes has become increasingly important as a food-borne pathogen. the aim of this study was to evaluate the effect of microwave (mw) treatment of chicken meat samples which were inoculated with l. monocytogenes. drumettes of broiler carcass...

BACKGROUND Campylobacteriosis contributes strongly to the disease burden of food-borne pathogens. Case-control studies are limited in attributing human infections to the different reservoirs because they can only trace back to the points of exposure, which may not point to the original reservoirs because of cross-contamination. Human Campylobacter infections can be attributed to specific reserv...

The world's most numerous bird, the domestic chicken, and their wild ancestor, the red junglefowl, have long been used as model species for animal behaviour research. Recently, this research has advanced our understanding of the social behaviour, personality, and cognition of fowl, and demonstrated their sophisticated behaviour and cognitive skills. Here, we overview some of this research, star...

More than 1000 complete or near-complete mitochondrial DNA (mtDNA) sequences have been deposited in GenBank for eight common domestic animals (cattle, dog, goat, horse, pig, sheep, yak and chicken) and their close wild ancestors or relatives, as well. Nevertheless, few efforts have been performed to evaluate the sequence data quality. Herein, we conducted a phylogenetic survey of these complete...

The present study was designed to establish a model of rotational behavior and its reversal through the use of neural grafting in the domestic fowl. Young sexually mature males of the chicken breed Black Silkie were utilized in this study. An initial experiment was conducted in order to select the appropriate drug for the induction of locomotor activity. Apomorphine induced locomotor activity i...

Abstract In Tanzania, diets are dominated by starchy staple crops such as maize, levels of malnutrition high and largely attributed to lack dietary diversity. We employed fuzzy cognitive mapping understand the current soybean, maize chicken value chains, highlight stakeholder relationships identify entry points for chain integration support nutritious in Tanzania. The maps were constructed base...

Knowledge of the genetic characteristics, origin, and local adaptation chickens is essential to identify traits required for chicken breeding programs. Chee Fah Luang are black-boned breeds reared in Chiang Rai, Thailand. Chickens an important part economy socio-culture; however, diversity, origins these two have been poorly studied. Here, we investigated gene pool, origin using mitochondrial D...

QUESTIONS UNDER STUDY To describe the current epidemiological situation of enteric salmonellosis in Switzerland and its development in the last two decades, particularly by determining the ratio between domestic and travel-associated cases. METHODS Between 1 February 2011 and 31 January 2012, 14 medical laboratories continuously reported their isolations of enteric salmonellae to the Federal ...
