  • Beschreibung: <jats:title>ABSTRACT</jats:title> <jats:p> Recent studies have demonstrated a wide geographic circulation of isolates of <jats:italic>Neisseria gonorrhoeae</jats:italic> that fail to produce prolyliminopeptidase (PIP). Tests based on the production of this enzyme are important elements of a number of identification systems for gonococci. We documented the appearance, expansion, and contraction of subtypes of 165 PIP-negative gonococci detected in an extended and systematic sample of the 3,926 <jats:italic>N. gonorrhoeae</jats:italic> isolates collected in Sydney, Australia, from July 2002 to September 2005. Their appearance, peak, and decline followed an “epidemic” curve. At the peak of their prevalence in 2003, PIP-negative gonococci comprised 22% of all isolates. Closely related phenotypes accounted for 162/165 of the PIP-negative gonococci. Algorithms for confirmation of <jats:italic>N. gonorrhoeae</jats:italic> should take account of the temporal and geographic variability of gonococci by utilizing two or more distinct confirmatory methods. </jats:p>
