Mannheimia bovis


Mannheimia bovis is a species of Gram-negative, facultatively anaerobic bacteria within the family Pasteurellaceae. It was first described in 2021 following its isolation from the lung of a cow that died from hemorrhagic pneumonia in Yunnan Province, China. The type strain is ZY190616T.

Morphology and physiology

Mannheimia bovis cells are Gram-negative, non-motile, pleomorphic rods measuring approximately 0.2–0.3 × 0.2–2.5 μm. They are facultatively anaerobic and non-spore-forming. Biochemically, they produce specific fatty acids and polar lipids and utilize coenzyme Q-7 as their sole respiratory quinone.

Genomic insights

The complete genome of M. bovis strain ZY190616T has been sequenced, consisting of a circular chromosome approximately 2.15 Mbp in size, with 2,029 protein-coding genes and 85 RNA genes. Genomic analysis has revealed genes involved in carbohydrate metabolism and potential virulence factors.
