This review describes the major species,number,breeding pattern,ratio of fenced to freely grazed goat,suscepti?bility to Schistosoma japonicum,pattern of S. japonicum infection,infection rate,intensity of infection,fecal contamination of goat that were bred in 5 marshland and lake provinces of Hunan,Hubei,Jiangxi,Anhui and Jiangsu,and two mountainous provinces of Yunnan and Sichuan,and demonstrates the associations of infected goat distribution with the distribution of infect?ed Oncomelania hupensis snails and humans. Considering the huge number of goat which were predominantly grazed freely in marshland and lake endemic regions of China,the high infection rate,numerous environmental pollution by goat feces,as well as the close correlation between the infected goat distribution and infected snail distribution,goat is considered as a major infec?tious source for schistosomiasis japonica in China,and to play a critical role in the transmission of the disease. Since the control of schistosomiasis in animals is critical to schistosomiasis interruption and elimination,it is suggested that the integrated man?agement of goat schistosomiasis should be included in the national schistosomiasis control program of China.

Objective To investigate the sensitivity of dihydroartemisinin against different developmental stages of Schistosoma japonicum, so as to understand the effect of dihydroarteminisin against on S. japonicum. Methods Mice were infected with 40 S. japonicum cercariae on the abdomen. Dihydroartemisinin was given intragastrically at different developmental stages of S. japonicum , and the mice were sacrificed 50 days post-infection, the adult worms were collected, and the worm reduction rates and female worm reduction rates were calculated. ① On the 2nd h, 3rd, 5th, 7th, 10th, 14th, 18th, 21st, 28th, 35th day post-infection, the mice were administered intragastrically with dihydroartemisinin at a single dose of 300 mg/kg, and the effect of dihydroarteminisin on different developmental stages of S. japonicum were observed. ② The mice were administered with different doses of dihydroartemisinin on the 7th or 35th day post-infection, and the dose-effect was explored. ③ The mice were administered on the 7th day post-infection and re-administered on the 35th day post-infection, respectively with different doses of dihydroartemisinin, and the effect was evaluated. Results The dihydroartemisinin at a single dose of 300 mg/kg had obvious effect on 7-day schistosomula and 35-day adult worms, with 64.81% and 60.47% of worm reduction rates and 73. 81% and 90.48% of female worm reduction rates, respectively. When the mice on the 7th day post-infection were administered with 200, 300, 400 and 600 mg/kg dihydroartemisinin, the worm reduction rates were 46.84% , 60.63% , 59.55% and 60. 21% , respectively, and the female reduction rates were 59.73% , 72.29% , 72.58% and 76.61 % , respectively. While in the mice on the 35th day post-infection, the corresponding rates were 47. 23% , 62.33% , 76.31% and 83.63% , respectively, and 59. 73% , 89. 36% , 89.65% and 93.96% , respectively. When the mice were treated twice with dihydroartemisinin on the 7th day and 35th day post-infection, the worm reduction rates were 58. 16% , 82.66% ,83.42% and 83.79% , respectively, and the female worm reduction rates were 68.69% , 90.43% , 93.74% and 94.63% , respectively.

Objective To research the homology of 18S small subunit ribosomal RNA(18S-rRNA) gene about Chinese Mainland and Philippine strains of Schistosoma japonicum,and Schistosoma mansoni,and the possibility to establish the PCR assay based on the gene for detecting the cercaria in a low density level. Methods The genomic DNAs of Chinese Mainland and Philippine strains of S.japonicum,and S.mansoni were extracted. The PCR assay was used to detect the identical target DNA elements in the above genome team and the homology of their genes was compared. The single cercaria was respectively treated with the method of heating in boiling water,the method of treating with ammonia and the method of treating with NaOH,HCl and ethanol,and the single treated cercaria and the single cercaria without treating were used as the templates to amplify the target DNA by using the PCR assay,and the detection rates of the PCR assay to detect the single cercaria treated with the different methods were calculated and compared. Results With the genomic DNAs of Chinese Mainland and Philippine strains of S.japonicum and S.mansoni as the templates,the target DNA element of which sequence length was 469 bp was all amplified by PCR. The target DNA was all amplified by PCR to the single cercaria treated with ammonia and the method of treating with NaOH,HCl and ethanol. However,only 50 percent of specimens of the single cercaria without treating and the single cercaria treated with the method of heating in boiling water were amplified to the target DNA by PCR. Conclusions The 18S-rRNA gene has the general homology among the species and strains of Schistosoma. The sensitivity of the PCR assay to detect the low density cercaria treated with ammonia or the method of treating with NaOH,HCl and ethanol is higher than that of the single cercaria without treating or treated with the method of heating in boiling water.
