Orders over this limit will be sent to NIAID for approval before shipment. The Philippine strain of Schistosoma japonicum (S. japonicum) was originally isolated from Leyte, Philippines in 1969 by Dr. Van der Schalie from the University of Michigan. The laboratory stock of the Philippine strain of S. japonicum was later mixed with an isolate provided by Dr. Sano, Hamamatsu University, Japan in 1977 to produce the current Philippine strain of S. japonicum. The origins of the Oncomelania hupensis (O. hupensis) subsp. quadrasi snail host are unknown. NR-21968 consists of up to 100 O. hupensis subsp. quadrasi infected with the Philippine strain of S. japonicum 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 possible 2-4 month prepatent period after exposure to miracidia (depending on the temperature). 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 an order of exposed O. hupensis subsp. quadrasi snails is 3 to 4 weeks.
