Abstract :
Rodent plagues cause a major problem for agriculture in many temperate regions, and immunocontraception offers a new method to control fertility in these and other pest vertebrates. However, it is difficult to find an effective carrier for contraceptives for large numbers of pest animals in the field. In a new study, Jackson et al. manipulated the mousepox virus to boost the immune response in infected mice Mus musculus when testing the basis for controlling their fecundity rates. However, all infected mice (and half of recently immunized mice) died. Despite these unexpected and dramatic results of the engineering of mousepox virus, immunocontraception remains the most promising method for fertility control and management of pest vertebrates.
