Do you distribute oocysts of Cryptosporidium parvum and cysts of Giardia intestinalis?

BEI Resources used to distribute oocysts of Cryptosporidium parvum up until 2008. Distribution was stopped due to low demand and the well documented loss of viability of oocysts after 4-6 months at 4oC. We do not distribute cysts of Giardia intestinalis due to difficulties in obtaining an external source and high probability of low demand for the cysts.

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.

Is the passage history available for viruses?

We make every attempt to get the detailed passage history from the depositing scientist during the acquisition process. At BEI Resources, every effort is made to maintain minimal passage number by employing a seed stock concept, minimizing the passage number from depositor seed material to distribution vial.
