Orders over this limit will be sent to NIAID for approval before shipment.
The Egyptian strain of Schistosoma haematobium (S. haematobium) was originally isolated circa 1950 from an unknown location in Egypt. The laboratory stock of the Egyptian strain of S. haematobium was later mixed with an isolate that was thought to be obtained from Abrawash (Cairo) by the Naval Medical Research Unit III, in 1977. The current Egyptian strain of S. haematobium was produced when the 1977 stock was mixed with another Egyptian isolate obtained in the 1980s. The Bulinus truncatus (B. truncatus) subsp. truncatus snail host was obtained from Egypt.
NR-21965 consists of up to 100 B. truncatus subsp. truncatus infected with the Egyptian strain of S. haematobium 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 an order of exposed B. truncatus snails (~ 100 snails) is 3 months. If 200 or more snails are ordered, a delay can be expected.
