Orders over this limit will be sent to NIAID for approval before shipment.
Schistosoma mansoni (S. mansoni), strain PR-1 was collected from infected snails in Arecibo, Puerto Rico in 1950.
S. mansoni, strain PR-1 is maintained in the M-line strain of Biomphalaria glabrata (B. glabrata). The M-line strain is descended from a cross between a S. mansoni resistant albino strain of B. glabrata, collected in Brazil, and a S. mansoni susceptible pigmented strain of B. glabrata, collected in Puerto Rico in 1944.
Strain PR-1 was maintained by NIH/NIAID until 1978, when it was brought to the Biomedical Research Institute.
NR-21961 consists of up to 100 B. glabrata, strain M-line, infected with S. mansoni, strain PR-1, in a petri dish.
Note: Infected snails are exposed to miracidia only a few days before shipment. Laboratories should be aware and take caution of possible cercarial exposure following a 4 week prepatent period after exposure to miracidia (depending on the temperature and species). BEI Resources recommends consulting personnel in your institution's Occupational Safety and Health office for clearance to receive and maintain the infected snails.
Shipments of snails ordered through BEI Resources will be shipped by Biomedical Research Institute in Rockville, MD. To set up a standing recurring order of snails or mice, please use the Schistosome Standing Order Reagent Request Form in the shopping cart.
Note: The approximate time required to fill orders of 200 or more exposed B. glabrata snails is 2 to 3 months.
