Physiological studies on Oncomelania nosophora, the vector snail of Schistosoma japonicum. II. Effect of starvation upon glycogen content of the snail soft tissue.
In the previous report (Yanagisawa et al., 1961) respiratory metabolism especially oxygen uptake of Oncomelania nosophora, an intermediate snail host of Schistosoma japonicum and effects of starvation upon it were investigated as the first step to lay a foundation toward the practice in the chemical control of this snail. Data obtained from the study on the effect of starvation revealed the gra...
متن کاملComparative Phylogenetic Studies on Schistosoma japonicum and Its Snail Intermediate Host Oncomelania hupensis: Origins, Dispersal and Coevolution
BACKGROUND Schistosoma japonicum causes major public health problems in China and the Philippines; this parasite, which is transmitted by freshwater snails of the species Oncomelania hupensis, causes the disease intestinal schistosomiasis in humans and cattle. Researchers working on Schistosoma in Africa have described the relationship between the parasites and their snail intermediate hosts as...
متن کاملThe molluscicidal effect of sodium pentachlorophanate and calcium arsenite on Oncomelania hupensis, a snail host of Schistosoma japonicum in China.
Sodium pentachlorophanate (P.C.P. Na) is now considered as one of the most promising molluscicides. Field experiments with this compound against Oncomelania nosophora in Japan were reported by McMullen and others (1948; 1951), and Hunter and others (1952). Since 1955 this compound has been used for practical molluscicidal purpose in the major endemic areas of schistosomiasis in Japan. In China,...
متن کاملStudies on antigenic communities between the Yamanashi and Chinese strains of Schistosoma japonicum eggs and Oncomelania snails by immunoelectrophoresis.
Antigenic communities were studied with sera from rabbits immunized with the Yamanashi and Chinese strains of Schistosoma japonicum eggs, and the antigens of five subspecies of Oncomelania snails, by immunoelectrophoresis. With regard to antigenic communities defined by the Yamanashi strain of S. japonicum eggs and Oncomelania snails, the schistosome egg produced 5 to 6 bands with Oncomelania h...
متن کاملDevelopment and Effects of Schistosoma japonicum (Trematoda) on its Intermediate Host, Oncomelania hupensis (Gastropoda)
BACKGROUND Trematodes belonging to the genus Schistosoma cause schistosomiasis. The relationship between schistosomes and their intermediate hosts varies among snails. This study investigated the effects of S. japonicum on its snail host, Oncomelania hupensis, and cercarial release rythmicity of S. japonicum and the effects of light on it. METHODS Seven groups of O. hupensis (n = 40 each) wer...
