AB In an effort to better diagnose, treat, and control sexually transmitted
diseases (STD), a number of new diagnostic assays using molecular
techniques have been developed. By incorporating molecular
amplification, the sensitivity for detecting sexually transmitted
infections has become markedly enhanced, and organisms that were
difficult or impossible to cultivate, such as human papillomavirus (HPV)
or Treponema pallidum can now be detected and monitored. By using
polymerase chain reaction (PCR) or ligase chain reaction (LCR), the
sensitivity of detecting some pathogens is comparable to, or in some
cases better than, direct in vitro cultivation of the agent. DNA
fingerprint analysis of amplified microbial DNA also has been
effectively used for detailed study of the epidemiology and
pathophysiology of sexually transmitted infections. In addition to
direct detection, molecular techniques have been used to enhance
serologic techniques by use of cloned proteins and recombinant antigens.
These techniques have enabled investigators to differentiate infection
caused by closely related pathogens, such as human immunodeficiency
virus type 1 (HIV-1) and HIV-2 and human T-cell lymphotrophic virus type
1 (HTLV-1) and HTLV-2. As a consequence of these molecular tools, the
diagnostic repertoire of the clinical laboratory for the diagnosis of
STD will expand significantly, allowing investigators to better diagnose
and more effectively control the spread of STD. However, with such new
technology, new problems and challenges have arisen, such as the risk of
sample contamination resulting in false-positive results, and the
presence of inhibitors resulting in false-negative results.(ABSTRACT
