AbstractDNA methylation is pivotal in orchestrating gene expression patterns in various mammalian biological processes. Perturbation of the bovine alveolar macrophage (bAM) transcriptome, due to Mycobacterium bovis (M. bovis) infection, has been well documented; however, the impact of this intracellular pathogen on the bAM epigenome has not been determined. Here, whole genome bisulfite sequencing (WGBS) was used to assess the effect of M. bovis infection on the bAM DNA methylome. The methylomes of bAM infected with M. bovis were compared to those of non-infected bAM 24 hours post-infection (hpi). No differences in DNA methylation (CpG or non-CpG) were observed. Analysis of DNA methylation at proximal promoter regions uncovered >250 genes harbouring intermediately methylated (IM) promoters (average methylation of 33–66%). Gene ontology analysis, focusing on genes with low, intermediate or highly methylated promoters, revealed that genes with IM promoters were enriched for immune-related GO categories; this enrichment was not observed for genes in the high or low methylation groups. Targeted analysis of genes in the IM category confirmed the WGBS observation. This study is the first in cattle examining genome-wide DNA methylation at single nucleotide resolution in an important bovine cellular host-pathogen interaction model, providing evidence for IM promoter methylation in bAM.

The bovine alveolar macrophage (BAM) was isolated in large numbers from lung washings and could be cultivated in vitro up to 63 days in medium 199, 20% foetal calf serum (FCS). Freshly isolated cells examined by electron microscopy (EM) were similar to those of the mouse. Cultured BAM prepared for EM were larger than fresh cells and contained discrete packets of homogenous material, possibly lipid. The BAM phagocytosed Staphylococcus aureus (FDA209P, type 42D) but the percentage of cells phagocytosing was reduced when FCS was not present, when cells were infected for 30 min compared with 45 min and when 2 × 107 CFU/ml compared with 2 × 108 CFU/ml were used to infect the cells.
