1. Detection of Snps in the Melanocortin 1-Receptor (MC1R) and Its Association with Shank Color Trait in Hs Chicken
ABSTRACT The melanocortin 1 receptor (MC1R) gene plays a key role in controlling the deposition of melanin. In mammals, the MC1Rgene is regarded as a major candidate gene in the control of melanin formation. In domestic animals, the MC1R gene mainly controls the expression of coat, skin, and plumage color in mammals and birds. In order to breed chickens with

2. The eco-epidemiology of Triatoma infestans in the temperate Monte Desert ecoregion of mid-western Argentina
BACKGROUND The eco-epidemiological status of Chagas disease in the Monte Desert ecoregion of western Argentina is largely unknown. We investigated the environmental and socio-demographic determinants of house infestation with Triatoma infestans, bug abundance, vector infection with Trypanosoma cruzi and host-feeding sources in a well-defined rural area of

3. The Identification of SNPs in BCDO2 Gene for Skin Color in Chinese Indigenous Chicken
ABSTRACT A complete linkage disequilibrium between the SNP (SNP B) in BCDO2 gene and the yellow skin phenotype in European domestic chicken has been reported. Here, we genotyped the reported SNPs (SNP A, SNP B, and SNP C) of the BCDO2 gene in 183 Chinese Indigenous chickens from 11 breeds/populations, including 57 yellow, 17 white, and 109 black skin chicken

4. Helminthic Parasites of Chickens (Gallus Domesticus) in Different Regions of São Paulo State, Brazil
Abstract The Brazilian poultry industry is an outstanding national and international agribusiness sector. Among the Brazilian states, São Paulo is the largest producer of commercial eggs and the fourth largest producer and exporter of chicken meat. Alternatively, semi-intensive and/or organic poultry production have also obtained a significant share of the

5. Toxoplasma Gondii and Neospora Caninum Antibodies in Backyard Chickens in Rio Grande do Sul, Brazil
Toxoplasma gondii and Neospora caninum are two intracellular apicomplexan protozoa with worldwide distribution, and are responsible for reproductive disorders in sheep and cattle. These protozoa may infect a wide variety of domestic and wild animals, including birds, and backyard chickens can be used as sentinels of their infection. Parasites investigation i

6. The peri-urban interface and house infestation with Triatoma infestans in the Argentine Chaco: an underreported process?
Peri-urban infestations with triatomine bugs, their sources and their dynamics have rarely been investigated. Here, we corroborated the reported occurrence of Triatoma infestans in a peri-urban area and in neighbouring rural houses in Pampa del Indio, in the Argentine Chaco, and identified its putative sources using spatial analysis and demographic questionn

7. Feeding behaviour of broiler chickens: a review on the biomechanical characteristics
Feed related costs are the main drivers of profitability of commercial poultry farms, and good nutrition is mainly responsible for the exceptional growth rate responses of current poultry species. So far, most research on the poultry feeding behaviour addresses the productivity indices and birds' physiological responses, but few studies have considered the b

8. Dissemination of Salmonella enteritidis by experimentally-infected pigeons
Two groups of domestic pigeons (Columba livia) were experimentally infected orally with doses of 9.5 x10(7) and 9.5 x10(9) CFU/mL (group A and B, respectively) of a Salmonella Enteritidis (SE) strain isolated from chickens. None of the used doses caused mortality of the inoculated birds; however, the pathogen was successfully recovered from the liver and spl

9. Genetic characterization of Bhutanese native chickens based on an analysis of Red Junglefowl (Gallus gallus gallus and Gallus gallus spadecieus), domestic Southeast Asian and commercial chicken lines (Gallus gallus domesticus)
The genetic diversity of Bhutanese chickens needs to be understood in order to develop a suitable conservation strategy for these birds in Bhutan. In this, work, we used microsatellite markers to examine the genetic diversity of Bhutanese chickens. Four Bhutanese chicken varieties (Black plumage, Frizzle, Naked neck and Red Junglefowllike, corresponding to Y

10. An overview on avian influenza
Avian influenza (AI) is considered an exotic disease in the Brazilian poultry industry, according to the National Avian Health Program (PNSA), with permanent monitoring of domestic, exotic and native avian species. Brazil presents privileged environmental conditions of reduced risk. In addition, all commercial poultry and conservation holdings are registered

11. Temporal differences in blood meal detection from the midguts of Triatoma infestans
We used genus/species specific PCRs to determine the temporal persistence of host DNA in Triatoma infestans experimentally fed on blood from six common vertebrate species: humans, domestic dogs, guinea pigs, chickens, mice, and pigs. Twenty third or fourth instar nymphs per animal group were allowed to feed to engorgement, followed by fasting-maintenance in

12. Soroprevalência de anticorpos anti-Toxoplasma gondii em animais domésticos e silvestres invasores do arquipélago de Fernando de Noronha, PE.
The Archipelago of Fernando de Noronha is known to possess a rich biological diversity, however, as in other islands of Brazil suffered various human activities. Among these actions, there is the introduction of invasive alien species, which can be sources of infection or reservoirs of zoonotic pathogens. The objective of this research was to determine the s
