title: Blood-culture techniques. A survey in Australasian laboratories.
abstract: The blood-culture methods of participants in the Microbiology Quality Assurance Programme were surveyed in late 1983; 183 participants from Australasia and S.E. Asia completed a questionnaire, the results of which are discussed. The choice of skin disinfectants varied widely. Conventional broth media were used by 85 participants; one or more diphasic bottles by 56; Roche Septi-Chek was used by 25; and BACTEC by 17. Only 80% of respondents reported the use of sodium polyanethol sulfonate. Contamination rates ranged from 0 to greater than 10%. Cultures were kept for as little as five days or as long as three weeks and were examined by inspection and/or Gram stain and/or subculture at widely varying intervals. While a great diversity of methods was used, in most cases these were adequate. The workload involved in some of the more laborious routines was considerable. It would be desirable to evaluate the cost-effectiveness of many blood culture practices.
