Bordetella bronchiseptica (B. bronchiseptica) causes a respiratory disease in rabbits. To determine the proteins of B. bronchiseptica in rabbits related to the disease, differentially accumulated proteins in B. bronchiseptica ‐infected cells are identified by comparative proteomic analysis. Comparative proteomic analysis detects 5814 proteins and quantifies 4854 of these. Fifty eight upregulated and 38 downregulated proteins are identified in spleen tissue after B. bronchiseptica infection of rabbits (both p < 0.05). The significantly enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways are ribosome, biosynthesis of amino acids, biosynthesis of amino acids, protein export, and carbon metabolism etc. (all p < 0.01). Significantly enriched KEGG pathways include ‘ocu03010 ribosome’ (a); ‘ocu00260 glycine, serine threonine metabolism’. Analyses of control and infected spleen cells detect responses to B. bronchiseptica infection. Many differentially affected proteins are evident, and reflect different biological changes and diverse subcellular localizations between control and infected spleen cells. Infection markedly alters the expressions of proteins linked to the serine protease system, with the ‘phagosome,’ ‘biosynthesis of amino acids,’ ‘glycine, serine threonine metabolism,’ ‘intestinal immune network for IgA production’, and ‘amino sugar and nucleotide sugar metabolism’ associated with B. bronchiseptica infection. The result will inform studies of responses to B. bronchiseptica infections in rabbits.
