Histophilus somni was proposed in 2003 as a common name for bacteria that earlier had been called "Haemophilus somni", "Haemophilus agni", "Haemophilus somnifer", and "Histophilus ovis". The species is clearly separated from other species and genera within the family Pasteurellaceae. The species is phenotypically variable, but highly uniform regarding the 16S rDNA sequence. Whole-genome sequencing has revealed distinct genetic differences between a commensal and a pathogenic strain, particularly in regard to putative virulence factors. However, broad generalizations regarding the genetics of H. somni cannot be applied to the entire species until the genomes of additional strains are sequenced.
2003年，睡眠嗜血杆菌被提议作为一种细菌的通用名称，该细菌此前被称为“睡眠嗜血杆菌”、“绵羊嗜血杆菌”、“产睡嗜血杆菌”和“绵羊组织ophilus菌”。该物种与巴斯德氏菌科内的其他物种和属明显区分开来。该物种在表型上具有变异性，但在16S rDNA序列方面高度一致。全基因组测序揭示了共生菌株和致病菌株之间明显的遗传差异，特别是在假定的毒力因子方面。然而，在对更多菌株的基因组进行测序之前，关于睡眠嗜血杆菌遗传学的广泛概括不能应用于整个物种。
