Hemolytic factors in Schistosoma japonicum eggs.
Extracts of Schistosoma japonicum eggs were found to exhibit hemolytic activity on erythrocytes of various species. The hemolytic reaction took place more rapidly at 37 degrees C than at 4 degrees C and did not require divalent cations. The degree of hemolysis was dependent on the concentration of the egg extracts. The hemolytic factors seemed to be lipid in nature because of being heat-stable ...
متن کاملStudies on hatchability of Schistosoma japonicum eggs in several external environmental conditions.
Several factors influencing the hatching of Schistosorna japonicum eggs were reported by Miyagawa (1916), Faust and Meleney (1924), Magath and Mathieson (1946), Faust (1947), Maldonado and Matienzo (1948), Ingalls et al (1949) and Sugiura et al (1954), but there were only a few investigators who have dealt with the resistance of the eggs to various external environmental conditions. These probl...
متن کاملA Novel Procedure for Precise Quantification of Schistosoma japonicum Eggs in Bovine Feces
Schistosomiasis japonica is a zoonosis with a number of mammalian species acting as reservoir hosts, including water buffaloes which can contribute up to 75% to human transmission in the People's Republic of China. Determining prevalence and intensity of Schistosoma japonicum in mammalian hosts is important for calculating transmission rates and determining environmental contamination. A new pr...
متن کاملA Deep Analysis of the Small Non-Coding RNA Population in Schistosoma japonicum Eggs
BACKGROUND Schistosoma japonicum is a parasitic flatworm that causes zoonotic schistosomiasis. The typical outcome of schistosomiasis is hepatic granuloma and fibrosis, which is primarily induced by soluble egg-derived antigens. Although schistosomal eggs represent an important pathogenic stage to the host, the biology of this critical stage is largely unknown. We previously investigated the ex...
متن کاملClinical diagnostic value of viable Schistosoma japonicum eggs detected in host tissues
BACKGROUND Schistosomiasis, one of the neglected tropical diseases, is endemic in more than 70 countries. However, the clinical diagnosis of patients with a low degree of infection is an unsolved technical problem. In areas endemic for schistosomiasis japonica, proctoscopy detection of eggs has been one method used for clinical diagnosis. However, it is often a challenge to find typical live eg...
