Psychrobacter cryohalolentis explained

Psychrobacter cryohalolentis is a Gram-negative, nonmotile species of bacteria.^[1] It was first isolated from Siberian permafrost. Its type strain is K5^T (=DSM 17306^T =VKM B-2378^T).

Hypoacylated lipopolysaccharide (LPS) from P. cryohalolentis induces moderate TLR4-mediated inflammatory response in macrophages and such LPS bioactivity may potentially result in the failure of local and systemic bacterial clearance in patients.^[2]
