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.
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.
