Project description:Bovine tuberculosis (bTB), caused by Mycobacterium bovis (Mycobacterium tuberculosis complex), is a zoonotic disease that affects cattle and wildlife worldwide. In some regions of Spain, Iberian red deer (Cervus elaphus hispanicus) can serve as reservoir of infection, thus increasing the risk of human and cattle exposure and infection. Mesenteric lymph nodes are naturally infected with M. bovis in Iberian red deer, in which the digestive route of infection is particularly important in Mediterranean Spain. In this study we characterized the differential expression of inflammatory and immune response genes in mesenteric lymph nodes of Iberian red deer naturally infected with M. bovis using a Ruminant Immuno-inflammatory Gene Universal Array (RIGUA) and real-time RT-PCR. Of the 600 genes that were analyzed in the microarray, 157 showed ? 1.2 fold changes in expression in infected or uninfected deer and 17 genes displayed an expression fold change greater than 1.7 with a P-value ? 0.05 and were selected for further analysis. These genes included tight junction proteins (Z02 and occluding), IL-11R, bactenecin, CD62L, CD74, desmoglein, IgA and IgM that constitute new findings and suggest new mechanisms by which M. bovis may modulate host inflammatory and immune responses. Identification of genes differentially expressed in animals and tissues naturally infected with M. bovis contributes to our basic understanding of the mechanisms of pathogenesis and protective immunity to mycobacterial infections and may have important implications for future functional genomic and vaccine studies to aid in the control of bTB in deer and other wildlife reservoir species. Mesenteric lymph node RNA from four different uninfected Iberian red deer stags and two Iberian red deer stags infected with Mycobacterium bovis. Infected animals were naturally infected with M. bovis. All animals were hunter-harvested and the tissues retrieved 2-6 hrs after animal hunting.

Project description:This study was aimed to elucidate a global antigenic profile of Mycoplasma bovis (M. bovis) with immunoproteomics, immunoinformatics, and gene expression approaches. The extracts of whole-cell proteins and TX-114 membrane fraction of a Chinese strain M. bovis HB0801 were separated with two dimensional gel electrophoresis (2-DE) and proteins reacting with antisera to M. bovis from experimentally infected calves were detected by MALDI-TOF MS.

Project description:The immune response associated with mastitis caused by Mycoplasma bovis is a very complicated biological process in several type of cells, including immune cells, mammary epithelial cells and, endothelial cells. Thus, revealing of the microRNAs in the Mycoplasma bovis infected mammary gland tissues is particularly important for the immune response mechanism to Mycoplasma bovis. Firstly, mammary gland tissue samples were collected from Holstein cows and screened for Mycoplasma bovis. Then, total RNA was isolated from mycoplasma bovis infected tissues and RNA sequencing was performed. After bioinformatics analysis, GO and KEGG analysis of target genes of identified microRNAs were conducted. Our results revaled that 24 of the known microRNAs were expressed differently and 13 of the novel microRNAs were expressed differently in Mycoplasma bovis positive tissues. The target genes of these microRNAs were found to be associated with especially inflammation pathways. In conclusion, this study demonstrated that identified miRNAs may be involved in the signaling pathways during mastitis case caused by Mycoplasma bovis.
