The Silky Fowl (SF) is known for its special phenotypes and atypical distribution of melanocytes among internal organs. Although the genes associated with melanocyte migration have been investigated substantially, there is little information on the postnatal distribution of melanocytes in inner organs and the effect of hyperpigmentation on the development of SF. Here, we analyzed melanocyte dis...

BACKGROUND The current study investigates the anti-stress effects of clove (Eugenia caryophyllus) extracts (0, 200, 400, and 600 mg/kg) on serum antioxidant biomarkers, immune response, immunological organ growth index, and expression levels of acute phase proteins (APPs); ovotransferrin (OVT), ceruloplasmin (CP), ceruloplasmin (AGP), C-reactive protein (CRP), and serum amyloid-A (SAA) mRNA in ...

The aim of this investigation was to detect and examine the distribution of the CD3–T lymphocyte cell population of the Bursa Fabricius in chickens experimentally infected with Eimeria tenella. Slices of archived samples of Bursa were examined using the of direct peroxidase (DP) method. CD3–T lymphocytes were detected with human anti-CD3 antibody. They were localized in the cortico-medullary la...

In the chicken, the bursa of Fabricius is essential for the development of lymphoid cells that will synthesize and secrete both IgM and IgG (1-3). WheI1 newly hatched chickens are bursectomized and irradiated, they fail to synthesize serum immunoglobulin(s) (Ig) 1 even though the expression of cell-mediated immunity remains normal. Hence, the bursa of the chicken provides an excellent experimen...

HOSHI, H. Effect of Inoculation of Bursa Cells on the Splenic Lymphoid Tissue of Bursectomized and X-irradiated Chickens. Tohoku J. exp. Med., 1972, 108 (2), 113-121 Bursectomized and X-irradiated chickens were given intraperitoneal inoculation of live bursa cells in an attempt to restore the periellipsoidal lymphoid cells in their spleens. An injection of viable cells prepared from autologous ...

The chicken is a foundational model for immunology research and continues to be a valuable animal for insights into immune function. In particular, the bursa of Fabricius can provide a useful experimental model of the development of B lymphocytes. Furthermore, an understanding of avian immunity has direct practical application since chickens are a vital food source. Recent work has revealed som...

Kulíková L. , V. Jurajda, R. Juranová: Effects of Infectious Bursal Disease Vaccination Strains on the Immune System of Leghorn Chickens. Acta Vet. Brno 2004, 73: 205-209. The detection of infectious bursal disease on chicken farms in the Czech Republic and problems related with it triggered the interest in the immunoprophylaxis of the disease in this country. In the present study, levels of po...

Utilizing degenerate PCR primers complementary to conserved regions within the kinase domain of Receptor Tyrosine Kinase (RTK) genes, the goal was to compare the full complement of RTK expressed (mRNA level) between two developmental stages of bursal B-cells. We identified 21 different RTK cDNAs out of a total of 235 cDNAs sequenced between the two B-cell stages. The dataset revealed the expres...

The genus Galathea is one of the most speciose and unwieldy groups in the family Galatheidae. The examination of more than 9000 specimens of 144 species collected in the Indian and Pacific Oceans using morphological and molecular characters, has revealed the existence of 92 new species. The specimens examined during this study were obtained by various French expeditions supplemented by other co...
