The major site of infection is a bloodstream infection and the specific site is either laboratory confirmed BSI or clinical sepsis. For example, a patient with leukemia with a vascular catheter has two positive blood cultures with coagulase negative staphylococci. Even if there are clinical signs and symptoms of localized infection at the vascular access site, but no other infection can be found, the infection is considered a primary bloodstream infection. Also, when a vascular access device is present and no other infection site is evident, then the BSI is considered a primary BSI regardless of whether there are localized signs of infection at the vascular access site.

Transmissible pathogenic agents that cause a variety of neurodegenerative diseases of humans and animals, including Scrapies in sheep and goats, bovine spongiform encephalopathy in cattle, and Kuru and Creutzfeldt-Jakob disease in humans. They are unlike any other infectious pathogens because they are composed of abnormal conformational isoforms of a normal cellular protein, and referred to as prion protein (PrP). Prions are extremely resistant to inactivation by sterilization processes and disinfecting agents.
