Objective: To develop a bionic animal skin and evaluate its detective effect of cercariae so as to provide a new technique for the monitoring of the schistosome susceptibility water body.

Methods: A bionic animal skin was made with pigskin and the experiments were carried out for evaluating its detective effects of cercariae in laboratory and simulate fields, and at the same time, the sentinel mouse method was used as the control.

Results: In the laboratory, the cercariae were found in 10-, 30-, 60-cercaria subgroups in the bionic animal skin group after 1 and 2 hours, but the cercariae were found only in the 60-cercaria subgroup in the sentinel mouse group.

Objective: To evaluate the effects of the project of ditching for drain on snail control and flood prevention security and explore the optimal engineering design plan in Dongting Lake region.

Methods: A retrospective study was performed on the previous studies about the project of ditching for drain. The reference values of project indices were determined.

Objective: To evaluate the effects of a novel molluscicide, the salt quinoid-2', 5-dichloro-4'-nitrosalicylanilide from niclosamide (LDS), with 10% wettable powder, in main schistosomiasis epidemic areas of China, including Hunan, Jiangxi, Hubei, Anhui, Jiangsu, Sichuan, Yunnan and Zhejiang Province.

Methods: In the immersion test, 6 effective concentrations of 10% LDS were tested respectively: 0.1, 0.

Article Synopsis
  • The study aimed to understand how the calcium cyanamide synthetic drug affects the morphology of Schistosoma japonicum eggs, with the goal of exploring the drug's mechanism against schistosome eggs.
  • Researchers mixed the drug with cattle feces containing the eggs and monitored changes over a week, comparing treated samples with blank controls.
  • Results showed that the treatment caused significant damage to the eggs, including color changes, atrophy of miracidia, and thickening of egg shells, with the effects worsening over time.

Article Synopsis
  • - The study highlights the growing concern over the role of migrants in the transmission of schistosomiasis in China, particularly in regions like Hunan where the disease is endemic, despite control efforts.
  • - A survey revealed that migrants represent a significant portion of the population in these areas (53.6%) and have a higher infection rate compared to permanent residents, mainly due to less awareness and lack of protective measures.
  • - The findings suggest that current schistosomiasis control programs fail to adequately include migrants, especially since they are often absent during health interventions, which could contribute to continued disease transmission.

Objective: To study the impact of environmental changes on the distribution and the growth and decline of Oncomelania snails in Dongting Lake beaches after the implementation of Three Gorges Project.

Methods: T-embankment of Junshan District where there was a greater human factor related to the snail spread and a lake beach named Dongkou of Junshan District where there was a less human factor related to the snail spread were selected as study areas. The various ground elevations were measured and the high points were marked with GPS.

[Toxicity test of Luokuwei on mice].

Article Synopsis
  • The toxicity test of Luokuwei on mice indicated that at doses 400-1,200 times higher than its molluscicidal dosage, the mortality rate for mice was relatively low, at 10%-20% over 24 hours.
  • Over a 14-day period, only the highest dosage group had a mortality rate exceeding 50%.
  • These findings suggest that Luokuwei is a molluscicide with low toxicity to mammals.
