Project description:Mycoplasma bovis is one of the major causative pathogens of the bovine respiratory complex disease that is characterized by enzootic pneumonia, mastitis, pleuritis and polyarthritis. M. bovis enters and colonizes the bovine respiratory epithelia through inhalation of aerosol from contaminated air. The nature of the interaction between M. bovis and bovine innate immune system is not well understood. We hypothesized that M. bovis invades blood monocytes and regulates cellular function to support its persistence and systemic dissemination. We used bovine-specific peptide kinome arrays to identify cellular signaling pathways that could be relevant to M. bovis-monocyte interaction in vitro. We validated these pathways using functional, protein and gene expression arrays. Here we show that infection of blood monocytes with M. bovis delays spontaneous or TNF-α/staurosporine-driven apoptosis, activates NF-κβ p65 subunit and inhibits caspase-9 activity. We also report that M. bovis infected bovine monocytes do not produce IFN-γ and TNF-α, although production of IL-10 is elevated. Our findings suggest that M. bovis takes over the cellular machinery of bovine monocytes to prolong bacterial survival and to possibly facilitate subsequent systemic distribution.

Project description:In order to gain a better understanding of MAP infection in immature macrophages, high-throughput sequencing technology was used to perform an analysis of miRNAs profiles of bovine monocyte derived macrophages upon MAP infection.The total numbers of raw reads collected from the MAP-infected and control MDM cells were 14.3 and 17.0 million raw reads per library.The length distribution of the clean reads was focused on 21–24 nt in length and read counts of 22 nt were highest.A total of 510 mature miRNAs were identified, among these a total of 433 miRNAs were homologous to bovine, while 77 were predicted as novel miRNAs that not homologous to any species.The analyses of differential expression revealed 21 DE miRNAs in MDM challenged with MAP compared to the control MDM, Among the DE miRNAs, 14 were upregulated and 7 were downregulated.Furthermore, The GO and KEGG pathway enrichment of these miRNA targets were performed.

Project description:Bovine Respiratory Syncytial Virus (BRSV) is a cause of Bovine Respiratory Disease (BRD). The objective of this study was to elucidate the chromatin regions which were differentially open in the bronchial lymph nodes (BLN) of dairy calves experimentally challenged with BRSV, relative to unchallenged control calves. Holstein-Friesian calves were either challenged with BRSV inoculum (n=12) or mock challenged with PBS (n=6). Calves were euthanised on day 7 post-challenge. ATAC-Seq libraries were prepared from fresh BLN tissues and sequenced (75 bp paired-end). Sequence reads were aligned to the UMD3.1 reference genome and peak calling (q < 0.01) was performed with MACS2, employing the BAMPE model. Using Diffbind, 9,144 and 5,096 differentially accessible peaks were identified between BRSV challenged and control calves (P < 0.05, FDR < 0.05) using DeSeq2 and EdgeR, respectively. There were 169 and 110 genes previously found to be differentially expressed using RNA-Seq located within or up to 2kb upstream of the differentially accessible peaks identified by the DeSeq 2 and EdgeR analyses, respectively. There were 237 differentially accessible peaks positioned within 40 previously identified susceptibility loci for BRD. These open chromatin regions are likely involved in the gene transcriptional and regulatory response to infection by BRSV.

Project description:Bovine Respiratory Syncytial Virus (BRSV) is a leading cause of Bovine Respiratory Disease (BRD) in young calves, which is responsible for substantial morbidity and mortality. Infection with BRSV induces global gene expression changes in respiratory tissues. If these changes are observed in tissues which are accessible in live animals, such as whole blood, they may be used as biomarkers of the disease. Therefore, the objective of the current study was to elucidate the whole blood transcriptomic response to an experimental challenge with BRSV, in dairy calves. Holstein-Friesian calves were either inoculated with virus (103.5 TCID50/ml x 15 ml) (n=12) or mock challenged with sterile phosphate buffered saline (n=6). Clinical signs were scored daily and whole blood was collected in Tempus RNA tubes immediately prior to euthanasia, at day 7 post-challenge. RNA was extracted from blood and sequenced (150 bp paired-end). Sequence reads were aligned to the UMD3.1 bovine reference genome and differential gene expression analysis was performed using EdgeR. An MDS plot displayed an obvious separation between BRSV challenged and control calves based on whole blood gene expression changes, despite an observed mild clinical manifestation of the disease. There were 281 differentially expressed (DE) genes (p < 0.05, FDR < 0.1, fold change > 2) between the BRSV challenged and control calves. The top enriched KEGG pathways and gene ontology terms were associated with viral infection and included “Influenza A”, “defense response to virus”, “regulation of viral life cycle” and “innate immune response”. Highly DE genes involved in these pathways are may be beneficial for the diagnosis of subclinical BRD from blood samples.
