72891-5Staphylococcus protein A spa gene [Presence] in Isolate or Specimen by NAA with probe detectionActive

Part Description

LP171728-1   Staphylococcus protein A spa gene
Protein A is a 56 kDa MSCRAMM surface protein originally found in the cell wall of the bacterium Staphylococcus aureus.

As a pathogen Staphylococcus aureus utilizes Protein A, along with a host of other proteins and surface factors to aid its survival and, thus, virulence. Protein A helps inhibit phagocytic engulfment and acts as an immunological disguise. Mutants of S. aureus lacking protein A are more efficiently phagocytosed in vitro, and mutants in infection models have diminished virulence. Higher levels of Protein A in different strains of S. aureus have been associated with nasal carriage of this bacteria.

Change Reason
Release 2.72: SYSTEM: Updated System from "Nose" to "Isolate/Specimen" according to the LOINC model molecular resistance terms; LONG_COMMON_NAME: Updated System from "Nose" to "Isolate/Specimen" according to the LOINC model molecular resistance terms. Changed the LCN to reflect the update of the system.; Previous Releases: The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; Removed parentheses in Component around "spa" based on current LOINC naming model.
