[Establishment and application of quality control system for detection of schistosomiasis in Jiangsu Province II Evaluation of pathogenic detection capacity of county-level personnel].

Objective: To evaluate the pathogenic detection capacity of countylevel organizations in Jiangsu Province, and to improve the field schistosomiasis detection capacity of professional personnel, thus to provide the technical support for the construction of quality control system of schistosomiasis field detection.

Methods: The eggs of were obtained from rabbit schistosomiasis models and were produced into suspensions at four different concentrations. The countylevel workers were invited to hatch the eggs, and the accuracy, detection error rate and omission rate were compared between the detection results and the standard results.

[Surveillance and risk assessment system of schistosomiasis in Jiangsu Province. I. Distribution of surveillance site and effectiveness of the system].

Objective: To establish the surveillance and risk assessment system of schistosomiasis in Jiangsu Province, so as to provide technical support for timely understanding of the risk of schistosomiasis transmission and implementation of targeted control measures.

Methods: The surveillance sites of schistosomiasis were assigned according to the epidemic status and endemic type of schistosomiasis as well as the characteristics of the water system, and the prevalence of Schistosoma japonicum in humans and domestic animals, and snail status were investigated. In addition, the quality control of serum detection of S.

[Optimization of time of artificial population schistosome infected Oncomelania hupensis snails].

Objective: To explore the optimizational time of artificial population schistosome infected Oncomelania hupensis snails.

Methods: Under laboratory conditions, the snails were infected with the miracidia of Schistosoma japonicum for 2 h, 3 h and 4 h respectively, and the death rates and the infection rates of the snails, and the quantities of cercariae of each group were observed 60-120 d after the infection, and all the data observed were analyzed to get the optimizational time of artificial population schistosome infected snails.

Results: Of the 3 h group, the snail infection rate was the highest and the mortality was the lowest among the 3 groups (P<0.

[Establishment and application of quality control system for detection of schistosomiasis in Jiangsu Province I ability of serological detection among county-level personnel].

Objective: To evaluate the ability for serological screening of schistosomiasis among county-level personnel, so as to provide the evidence for establishing the quality control system of field detection of schistosomiasis.

Methods: The standard serum panel was prepared for the quality assessment of schistosomiasis diagnostic capability, and detected by county-level personnel in the endemic field simultaneously using single-blind method. The rates of coincidence, misdiagnosis and missed diagnosis were calculated compared with the standard results.
