| variable maturation and oviposition by female schistosoma japonicum in mice: the effects of irradiation of the host prior to infection. | the maturation of female schistosoma japonicum was found to vary greatly within each of two philippine strains of this parasite and some females did not contain uterine eggs 7 to 15 weeks after infection while others contained numerous eggs before the fifth week of infection. it was found that female worms containing less than 20 uterine eggs contributed little to the accumulation of eggs in the tissues of infected mice. such worms also generally appeared to be immature. the variable rate of mat ... | 1987 | 3688308 |

| schistosoma japonicum: the modulation of lung granuloma and inhibition of egg maturation in mice by human sera. | human sera taken from patients with chronic schistosomiasis japonica have been demonstrated to have two effects on mice. sera from those patients reduced the size of granuloma in mice sensitised for accelerated granuloma formation to eggs entrapped in the lungs of mice injected with the sera shortly before and at day 2 after intravenous egg challenge. the sera with this effect on the mouse lung granuloma models caused large segmented precipitates in the optimised circumoval precipitin test (copt ... | 1985 | 3935128 |
