Host-pathogen relationships in aoudad (Ammotragus lervia) and bighorn sheep (Ovis canadensis) with respiratory disease agents

ABSTRACT: To evaluate transmission propensity of Mycoplasma ovipneumoniae and leukotoxigenic Pasteurellaceae from aoudad and bighorn sheep, we assessed the transcriptomic signals from bulk lung and tracheobronchial lymph node samples of aoudad and bighorn sheep exposed to Mycoplasma ovipneumoniae in either the presence or absence of leukotoxigenc Pasteurellaceae. Our aim was to determine gene expression patterns related to respiratory pathogenic exposure within nonindigenous aoudad and native bighorn sheep to provide crucial information related to respiratory pathogenesis and identify potentially predictive patterns in individuals as it relates to interspecific contact and mortality events.

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.
