Susceptibility of new Taiwan foci of Oncomelania hupensis to geographic strains of Schistosoma japonicum. 1980

J H Cross, and C T Lo

Six new recently identified Taiwan Oncomelania hupensis foci were exposed to miracidia from the Changhua Taiwan zoophilic and Indonesian and Philippine anthropophilic strains of Schistosoma japonicum. All new foci were found susceptible to infection in varying degrees. In general the new foci were more susceptible to the Changhua zoophilic strain of S. japonicum than the anthropophilic strains; 17% exposed to the zoophilic strain shed cercariae while 9% and 7%, respectively, of those exposed to the Indonesian and Philippine human strains demonstrated infection. These snails along with O.h. chiui on Taiwan could possibly serve as intermediate host for human oriental schistosomiasis if the parasite was accidentally introduced onto Taiwan.

D012549	Schistosoma japonicum	A species of trematode blood flukes belonging to the family Schistosomatidae whose distribution is confined to areas of the ASIA, EASTERN. The intermediate host is a snail. It occurs in man and other mammals.	Schistosoma japonicums,japonicum, Schistosoma
D012552	Schistosomiasis	Infection with flukes (trematodes) of the genus SCHISTOSOMA. Three species produce the most frequent clinical diseases: SCHISTOSOMA HAEMATOBIUM (endemic in Africa and the Middle East), SCHISTOSOMA MANSONI (in Egypt, northern and southern Africa, some West Indies islands, northern 2/3 of South America), and SCHISTOSOMA JAPONICUM (in Japan, China, the Philippines, Celebes, Thailand, Laos). S. mansoni is often seen in Puerto Ricans living in the United States.

D012908	Snails	Marine, freshwater, or terrestrial mollusks of the class Gastropoda. Most have an enclosing spiral shell, and several genera harbor parasites pathogenic to man.	Snail
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
