Human Biological Liquids Culture

LIGHT SCATTERING TECHNOLOGY APPLIED TO BACTERIAL CULTURE

The rapid analysis of human biological liquids is important to patients for whom the timely diagnosis and beginning of adequate therapy can make a difference to their prognosis. In addition to community acquired infections, hospital acquired infections have noticeable impact on public health. Their increased morbidity and mortality rates as well as prolonged hospital stays represent additional diagnostic and treatment costs.

  • Alfred 60 and HB&L automated systems are designed for human biological liquids and offer high sensitivity and specificity.
  • Using patented light scattering technology the Alfred 60 and HB&L are able to monitor bacteria replication activity from the inoculum step into specific culture broths providing real time growth curves.
  • Quantitative bacterial count results are reported in CFU/ml.
  • Due to the optimization of the broth it is possible to perform the bacterial culture in sterile endocavitary samples such as respiratory fluids, cerebrospinal fluid and pleural fluid offering a sensitivity of 1 CFU/ml in 6 hours.
  • Enhanced liquid culture media combined with a specific supplement (DEB) has been developed to detect aerobic bacteria and exigent micro-organisms such as Haemophilus influenza, Neisseria meningitidis as well as samples characterized by extremely low bacterial counts.
  • Broths are contained in sterile vials with pierceable hermetic seals, thus considerably reducing contaminations.
  • Samples are incubated at 37°C and constantly mixed avoiding sedimentation, flotation and growth anomalies typical of several micro-organisms.
  • Only live bacteria are detected while interference from non replicating substances such as erythrocytes, leukocytes, dead cells and salts present in the sample are eliminated during the initial zero reading.
