QIMR Berghofer is committed to the ethical care and use of animals for scientific purposes in our world-class Animal Facility and Insectory.

PC3 facility Anopheles stephensi

We maintain three separate Anopheles stephensi colonies, with a new generation starting each week to be able to supply mosquitoes on any day needed for experiments inside a PC3 facility. The infection of female mosquitoes with the malaria parasite, Plasmodium falciparum is studied, with novel strategies to interrupt this process, as well as the testing of new control measures aimed at the mosquito vector. Anopheles stephensi eggs can also be supplied to be used inside other registered PC2 and PC3 facilities.

For transmission studies in a clinical trial up to 4500 females of a specific age are used in membrane feeding assays over a two-week period, for which approximately 18 000 mosquito larvae are maintained at 29°C. Plasmodium falciparum infected blood is given to mosquitoes whereafter they are maintained at a constant temperature and humidity inside an environmental chamber. There are 12 glass membrane feeders available for the feeding of Plasmodium infected blood to the mosquitoes. The female mosquitoes are dissected to determine infectivity at oocyst and sporozoite level.

Our World Class facilities and Equipment include:

  • a surgical suite with surgical microscope and heated recovery rack
  • irradiation facilities
  • ventilated cage racks and change stations
  • Transnetyx TAG Center collection point for genotyping
  • IVIS in vivo imaging system
  • Visualsonics Vevo3100 ultrasound equipment with injection mount.
