Abstract
The bursa of Fabricius (BF) is the critical humoral immune organ to birds, playing an essential role in B lymphocyte differentiation. However, unlike other poultries, surgical removal of pigeon BF did not limit humoral immune responsiveness. To investigate the expression profiles and the potential role of mRNA and long non-coding RNA (LncRNA) in squab BFs, transcriptome analysis was performed by RNA-Sequencing (RNA-Seq) over three developmental stages (1-day, 13 and 26 days old). We identified 13,072 mRNAs and 19,129 lncRNAs, of which 2,752 mRNAs and 1,515 lncRNAs were differential expressed (DE) in pigeon BFs over three developmental stages. Cluster analysis presented different expression patterns in DE mRNAs and lncRNAs. Functional enrichment analysis revealed that DE lncRNAs and mRNAs with distinct expression patterns might play crucial roles in the immune system process and tissue morphogenesis. In particular, some DE genes and lncRNAs with higher expression levels in 13D or 26D are related to lymphocyte activation and differentiation, adaptive immune response, positive regulation of immune response, leukocyte migration, etc. Protein-protein interaction (PPI) network and Molecular Complex Detection (MCODE) analysis sreened six significant modules containing 37 genes from immune-related DE gene cluster, which is closely linked in B cell activation, lymphocyte differentiation, B cell receptor signaling pathway, etc. Our study characterizes mRNA and lncRNA transcriptomic variability in pigeon BFs over different developmental stages and enhances understanding of the mechanisms underlying physiological functions of pigeon BF.

Abstract
The ethical and logistical challenges inherent in experimental infections of wild-caught animals present a key limitation to the study of wildlife diseases. Here we characterize a potentially useful domestic model for a wildlife disease that has been of particular interest in recent decades; that is, infection of North American house finches (Carpodacus mexicanus) with Mycoplasma gallisepticum, more commonly known as a worldwide poultry pathogen. Seven domestic canaries (Serinus canaria domestica) were infected experimentally with M. gallisepticum alongside two wild-caught house finches (C. mexicanus) and the resulting clinical disease, pathogen load, serology and pathology were compared. Although rates of morbidity were higher in domestic canaries in response to M. gallisepticum infection, no significant differences were detected between the two species in the four measures of infection and disease studied. Our results support previous field and experimental studies that have documented universal susceptibility to M. gallisepticum infection in the avian family Fringillidae, which includes domestic canaries. Our results also indicate that domestic canaries may serve as a potentially useful model system for the experimental study of M. gallisepticum infection in songbirds.

Abstract
The aim of this study was to develop an immunological model of avian Aspergillosis by studying the humoral response of pigeons to Aspergillus fumigatus antigens. Immunization was performed by administering weekly injections of A. fumigatus extracts for 70 days (10 weeks). A new booster injection was given 270 days (9 months) following the last immunization. Results showed an early Aspergillus-specific humoral immunoresponse which reached a maximum level at 42-63 days (6-9 weeks) post-immunization. Using the ELISA method, it could be observed that A. fumigatus-specific IgG became elevated in the 2nd week and reached a maximum titre at 63rd day (9th week). In contrast, A. fumigatus-specific IgM levels appeared early showing maximum levels at the 2nd week, after which they declined despite the maintenance of antigenic stimulation. Termination of immunization resulted in the decrease of specific humoral immunoresponse with minimal levels of specific antibodies detectable 210 days (7 months) later. A booster injection given at 270 days (9 months) induced a very fast Aspergillus-specific IgM and IgG immunoresponse, reaching levels of antibodies similar to those observed during the immunization period.
