Cell Culture

Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are chemically treated to facilitate cell attachment. However, a few cell types, such as hematopoietic cells, can grow in a suspension. In contrast to adherent cultures, suspension cultures can grow in non-treated cultureware using magnetic stirrers or spinner flasks to agitate the culture media

Area of Science:

  • Microbiology
  • Clinical Diagnostics

Background:

  • Automated blood-culture systems improve microorganism recovery from sterile body fluids compared to traditional methods.
  • Laboratories often receive small-volume fluid samples, posing challenges for traditional culture techniques.

Purpose of the Study:

  • To evaluate the URO-QUICK system for organism enrichment and microbial count determination in various fluid samples.
  • To assess the system's capability in detecting residual antimicrobial activity (RAA).

Main Methods:

  • The URO-QUICK system was used to process 546 diverse fluid samples, including aspirates, lavage, sputum, blood, and various effusions.
  • Organism recovery, microbial counts, and RAA were compared against conventional culture procedures.

Main Results:

  • The URO-QUICK system increased microorganism recovery by 8% (p=0.007) compared to traditional methods.
  • The RAA test showed 100% specificity and positive predictive value.
  • Microbial counts obtained with the URO-QUICK system demonstrated excellent agreement with conventional enumeration.

Conclusions:

  • The URO-QUICK system is a promising alternative for microorganism recovery and enumeration from small fluid samples.
  • The system offers reliable assessment of residual antimicrobial activity.
