Do you have any tips for growing Anaerobes?
  • Start with the media on the product sheet.
  • Make sure the environment is truly anaerobic by using indicator strips in any containers or anaerobic chambers. There are chemical indicators that can be added to liquid media as well. If your laboratory cannot produce a truly anaerobic media, consider purchasing media made under anaerobic conditions.
  • Pre-reduce all media prior to inoculating.
  • Spot some of the anaerobic growth on a rich media, such as tryptic soy with 5 % sheep& rsquo s blood, and inoculate aerobically to check for contamination.

Will the use of pooled strains of M. leprae result in variability in the expressed proteins?

The M. leprae strains are highly clonal with little genetic variation, making the expressed proteins the same between the different strains.
