The objective of this research was to determine the effect of chlorine, acidified sodium chlorite, and peracetic acid treatments on viable Campylobacter jejuni located at various depths within follicles or folds of chicken skin. Chicken skin was inoculated with C. jejuni transformed with P(c)gfp plasmid (GFP-Campylobacter), which also codes for kanamycin resistance. Effectiveness of sanitizer t...
This special issue on the development and evolution of the amniote integument begins with a discussion of the adaptations to terrestrial conditions, the acquisition of water-impermeability of the reptilian integument, and the initial formation of filamentous integumentary appendages that prepare the way towards avian flight. Recent feather fossils are reviewed, and a definition of feathers is d...
The antioxidant activity and cell viability of feather hydrolysates obtained with the Bacillus licheniformis were evaluated using an in-vitro model. results indicate that feathers-derived peptides under 3 kDa have IC50 values 5.03 ± 0.215 mg/mL by DPPH assay. Although preserved after applying diverse heating (from 20 to 100 °C), they lost their strongly acidic or alkaline conditions. Antioxidan...
Recent studies have demonstrated that non-coding RNAs (ncRNAs) play important roles during development and evolution. Chicken, the first genome-sequenced non-mammalian amniote, possesses unique features for developmental and evolutionary studies. However, apart from microRNAs, information on chicken ncRNAs has mainly been obtained from computational predictions without experimental validation. ...
To assess the effect of various vaccine strains on replication and shedding of virulent Marek's disease virus from experimentally infected chickens, quantitative PCR (q-PCR) methods were developed to accurately quantify viral DNA in infected chickens and in the environment in which they were housed. Four groups of 10 chickens, kept in poultry isolators, were vaccinated at 1 day old with one of ...
Chemical phosphorylation of hydrolysate resulting from hydrothermal carbonization chicken feather waste was performed to enhance the amino acids and reduce metal ions content. The aim this research is improve functional properties feathers without impairing nutritional availability thereof with cheapest chemical method by phosphorylation. Phosphorylated can function as animal feed fertilizer. o...
