Periprosthetic Joint Infection Caused by Gram-Positive Versus Gram-Negative Bacteria: Lipopolysaccharide, but not Lipoteichoic Acid, Exerts Adverse Osteoclast-Mediated Effects on the Bone J Clin Med . Lipopolysaccharide- and gram-positive bacteria-induced cellular inflammatory responses: role of heterotrimeric G i proteins Hongkuan Fan,1 Basilia Zingarelli,2 Octavia M. Peck,1 Giuseppe Teti,3 George E. Tempel,1 Perry V. Halushka,4,5 and James A. Cook1 1Departments of Physiology and Neuroscience, 4Pharmacology, and 5Medicine, Medical Gram positive bacteria have cell walls composed mostly of a substance unique to bacteria known as peptidoglycan, or murein. These bacteria stain purple after Gram staining. Gram negative bacteria have cell walls with only a thin layer of peptidoglycan and an outer membrane with a lipopolysaccharide component not found in Gram positive bacteria. LPS are found on the outer membrane of Gram-negative bacteria. Gram-negative bacteria, such as E. coli and Salmonella, are a type of bacteria that often cause health problems and resist antibiotics (many probiotics, on the other hand, are gram-positive bacteria).

Periprosthetic joint infection (PJI)-the most common cause of knee arthroplasty failure-may result from Gram-positive (GP) or Gram-negative (GN) bacterial infections. The question as to whether PJI due to GP or GN bacteria can lead to different rates of aseptic loosening after reimplantation remains open.
