BEZERRA, Fernando Schemelzer de Moraes et al. Effect of gamma radiation on the activity of hemocytes and on the course of Schistosoma mansoni infection in resistant Biomphalaria tenagophila snails. Mem. Inst. Oswaldo Cruz [online]. 2003, vol.98, n.1, pp.73-75. ISSN 0074-0276. http://dx.doi.org/10.1590/S0074-02762003000100010.
High doses of gamma radiation (10 Krad) in Biomphalaria tenagophila snails (Taim strain), which have been found to be resistant to Schistosoma mansoni, were not sufficient to impair their resistance to the parasite. The number of hemocytes, as well as their phagocytic activity, were not affected by irradiation, thus showing resemblance with mammal macrophages, which are resistant to gamma irradiation also.
