      Articles on Bursa of Fabricius

      1. Development of a tailored vaccine against challenge with very virulent infectious bursal disease virus of chickens using reverse genetics.

        Vaccine 29(33):5550-7 (2011) PMID 21658423

        Due to the problems associated with traditional methods for infectious bursal disease virus (IBDV) vaccine development and the pressure of evolution and variation of very virulent strains, it is urgent to develop IBDV vaccine rapidly with novel approaches. Using reverse genetics, the...
      2. Effect of a commercial paratyphus vaccine on the development of pigeon circovirus infection in young pigeons (Columba livia domestica).

        J Avian Med Surg 24(2):107-14 (2010) PMID 20806655

        Infection with pigeon circovirus (PiCV) has been associated with young pigeon disease syndrome (YPDS), which is considered to be a multifactorial disease. The factors that determine whether birds succumb to clinical disease are not known. To evaluate the potential effect of vaccination with a commer...
      3. Histochemical and histological evaluations of the effects of high incubation temperature on embryonic development of thymus and bursa of Fab...

        Br Poult Sci 51(1):43-51 (2010) PMID 20390568

        These results give some morphological evidence for immunosuppression induced by high temperature exposure during the embryonic development. Temperature distribution and air circulation in incubator should be questioned in the case of lower broiler flock immunity....
      4. Development of SYBR green I based one-step real-time RT-PCR assay for the detection and differentiation of very virulent and classical strai...

        J Virol Methods 161(2):271-279 (2009) PMID 19591873

        I based one-step real-time reverse transcriptase polymerase chain reaction was developed for the detection and differentiation of very virulent (vv) and classical strains of infectious bursal disease virus (IBDV). The assay showed high PCR efficiency >93% and high reproducibility with coefficient of...
      5. Identification and characterization of two distinct bursal B-cell subpopulations following infectious bursal disease virus infection of Whit...

        Avian Dis 53(3):347-55 (2009) PMID 19848071

        Infectious bursal disease virus (IBDV) is an immunosuppressive virus which primarily infects IgM B-cells in the bursa of Fabricius. Flow cytometric analysis was used to phenotype B-cell populations in the bursa and spleen following IBDV infection. In the bursa, two IgM B-cell subpopulations, designa...
      6. Experimental study on respiratory cryptosprodiosis.

        J Egypt Soc Parasitol 39(2):599-605 (2009) PMID 19795766

        Cryptosporidiosis has a worldwide geographical and zoological distribution. Cryptosporidium baileyi oocysts were isolated from the bursa of Fabricius (BF) of 4 weeks-old of 100 broilers. Twenty five broiler chicks of 2 day old free from cryptosporidial infection were inoculated intratracheally at a...
      7. The Diagnosis of Very Virulent Infectious Bursal Disease in California Pullets

        Avian Dis 53(2):321-326 (2009) PMID 19630244

        This report documents the occurrence of a very virulent infectious bursal disease virus (vvIBDV) in Northern California commercial brown pullets. Diagnosis was made from multiple accessions from two neighboring and epidemiologically related ranches submitted to the California Animal Health and Food...
      8. Systemic Histomoniasis Associated with High Mortality and Unusual Lesions in the Bursa of Fabricius, Kidneys, and Lungs in Commercial Turkey...

        Avian Dis 53(2):231-238 (2009) PMID 19630229

        An outbreak of systemic histomoniasis in 9-to-11-wk-old meat-type male turkeys associated with high mortality is reported. Clinical signs in turkeys included anorexia, depression, diarrhea, loss of weight, and increased mortality between 7 and 13 wk of age. Seven-week cumulative mortality in the tur...
      9. Pathogenicity of infectious bursal disease virus variant AL2 in young chickens.

        Avian Dis 53(1):78-82 (2009) PMID 19432007

        We speculate that the changes in splenic CD4+ and IgM+ cell populations are associated with protective immune responses against IBDV in the host....
      10. Identification of microRNA in the developing chick immune organs.

        Immunogenetics 61(3):231-40 (2009) PMID 19198828

        We pyrosequenced four small RNA libraries derived from the spleen and the bursa of Fabricius of embryonic chicks at days 15 and 20 of development. A total of 90,322 sequence reads were obtained, among which 44,387 reads represented known chicken miRNAs, 3,503 reads were not found in the Gallus gallu...
