Project description:The Bashbay sheep (Ovis aries), an indigenous breed of Xinjiang, China, has many excellent characteristics. However, hybrids of Argali sheep and Bashbay sheep are susceptible to Mycoplasma ovipneumoniae infection, the causative agent of mycoplasma ovipneumonia, a chronic respiratory disease that is harmful to the sheep industry. To date, knowledge regarding the mechanisms responsible for M. ovipneumoniae pathogenesis is in scant. Herein, we report the results of transcriptome profiling of lung tissues from Argali hybrid sheep experimentally infected with an M. ovipneumoniae strain at 4 and 14 days post-infection, in comparison to mock-infected animals (0 d). Transcriptome profiling was performed by deep RNA sequencing, using the Illumina platform. The analysis of differentially expressed genes was performed to determine concomitant gene-specific temporal patterns of mRNA expression in the lungs after M. ovipneumoniae infection. We found 156 differentially expressed genes (44 up-regulated, 112 down-regulated) when comparing transcriptomic data at 4 and 0 days post-infection, and 367 (35 up-regulated, 332 down-regulated) when comparing 14 versus 0 days post-infection. Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that the differentially expressed genes at 4 and 14 versus 0 days post-infection were enriched in 109 and 150 pathways, respectively, and the Primary immunodeficiency pathway was considered most closely related to MO infection (p < 0.01). Hyper-IgM syndrome was identified based on the B-cell immunodeficiency signaling pathway from differentially expressed genes related M. ovipneumoniae infection. Gene Ontology analysis showed that differentially expressed genes in different groups were enriched for 497 and 928 terms, where those most closely related to M. ovipneumoniae infection are ciliated motor damage (p < 0.01). These results could aid in understanding why the Argali hybrid sheep are susceptible to MO as well as how M. ovipneumoniae infection progresses in the lungs and may provide useful information regarding key regulatory pathways.

Project description:Bashbay sheep (Ovis aries), an indigenous breed of Xinjiang, China, has many excellent characters. It is resistant to Mycoplasma ovipneumoniae (MO) infection, the causative agent of Mycoplasma ovipneumonia, a chronic respiratory disease, which is harmful to the sheep industry. As of date, knowledge regarding the mechanisms responsible for MO pathogenesis in scant. Herein, we report the results of transcriptome profiling of the lung tissue of Bashbay sheep experimentally infected with M. ovipneumoniae strain at 4days post-infection(DPI) and 14DPI in comparison to the mock-infected animals (0d), which was performed by Illumina deep sequencing (RNASeq). The analysis of differentially expressed genes (DEGs) was performed to determine the concomitant gene-specific temporal patterns of mRNA expression in the lung after MO infection. The results showed 1048 DEGs (up-regulated: 575; down-regulated: 473) were screened at 4DPI compared to 0d, and 2823 DEGs (up-regulated: 1362; down-regulated: 1461) were screened at 14DPI compared to 0d. KEGG analysis found that the DEGs at 4DPI and 14DPI compared to 0d were enriched in 245 and 287 pathways respectively, the most closely related to MO infection of which was TLR signaling pathway (p<0.01). Two pathways (First: LAMP-TLR2/TLR6-MyD88-MKK6-AP1-IL1B; Second: LAMP-TLR8- MyD88-IRF5-RANTES) were obtained from the figure of TLR signaling pathway that DEGs related with MO infection were mapped to. GO analysis found that the DEGs in different groups were enriched to 1580 and 4561 terms, the most closely releted to MO infection of which was positive regulation of inflammatory response (p<0.01).Our study shouldpave the road for the further analysis of Mycoplasma ovipneumonia.

Project description:We used RNA-seq to investigate gene expression changes in sheep mammary gland and spleen tissue after experimental infection with Mycoplasma agalactiae (strain PG2). Sheep (3 per each group) were given an intra-mammary infection with 10^9 cfu infectious organisms or PBS as control. The animals were euthanized 15 days post infection to obtain the samples. Two replicates of mammary gland and spleen tissue per animal were used for Illumina RNA-sequencing.

Project description:BackgroundBronchopneumonia is a population limiting disease of bighorn sheep (Ovis canadensis). The cause of this disease has been a subject of debate. Leukotoxin expressing Mannheimia haemolytica and Bibersteinia trehalosi produce acute pneumonia after experimental challenge but are infrequently isolated from animals in natural outbreaks. Mycoplasma ovipneumoniae, epidemiologically implicated in naturally occurring outbreaks, has received little experimental evaluation as a primary agent of bighorn sheep pneumonia.Methodology/principal findingsIn two experiments, bighorn sheep housed in multiple pens 7.6 to 12 m apart were exposed to M. ovipneumoniae by introduction of a single infected or challenged animal to a single pen. Respiratory disease was monitored by observation of clinical signs and confirmed by necropsy. Bacterial involvement in the pneumonic lungs was evaluated by conventional aerobic bacteriology and by culture-independent methods. In both experiments the challenge strain of M. ovipneumoniae was transmitted to all animals both within and between pens and all infected bighorn sheep developed bronchopneumonia. In six bighorn sheep in which the disease was allowed to run its course, three died with bronchopneumonia 34, 65, and 109 days after M. ovipneumoniae introduction. Diverse bacterial populations, predominantly including multiple obligate anaerobic species, were present in pneumonic lung tissues at necropsy.Conclusions/significanceExposure to a single M. ovipneumoniae infected animal resulted in transmission of infection to all bighorn sheep both within the pen and in adjacent pens, and all infected sheep developed bronchopneumonia. The epidemiologic, pathologic and microbiologic findings in these experimental animals resembled those seen in naturally occurring pneumonia outbreaks in free ranging bighorn sheep.
