| 1 | 桑给巴尔地区养殖番鸭对水泡螺生存繁殖影响的观察显示文摘目的初步探讨在桑给巴尔血吸虫病流行区采用养殖番鸭捕食水泡螺进行生态灭螺的效果。方法选择中国援桑给巴尔血吸虫病防治技术合作项目组在奔巴岛实验基地的菜园作为实验观察区,饲养2只番鸭。设置实验组和对照组,对照组周围设置栅栏隔开以阻止番鸭进入。于第10、20、30、40天,采取全面细查法调查水泡螺成螺及子代螺数量,并计算成螺存活率。通过直接观察法,观察番鸭捕食水泡螺的行为。结果第10、20、30、40天实验组水泡螺成螺存活率均低于对照组,差异有统计学意义(χ~2=7.566、20.671、18.039、19.200,P均<0.05);实验组水泡螺子代螺数量为13~60只,低于对照组的320~963只。番鸭在嘴部滤水或吞食蔬菜时,可利用喙部碾碎或直接吞食成年水泡螺;子代水泡螺由于体型极小,更易被吞食。结论养殖番鸭可以抑制水泡螺生长繁殖,提示可用于生态灭螺。 | 唐恺 陈晓军 何健 吴平进 Saleh Juma Mohamed 吴洪初 杨坤 | 2021 | 热带病与寄生虫学2021，19，2： | 1 |
| 2 | Potential risk of colonization of Bulinus globosus in the mainland of China under climate change显示文摘Background: Bulinus globosus,the main intermediate snail host of Schistosoma haematobium.The increased contacts between Africa and China could even lead to large-scale dissemination of B.globosus in China.Temperature is the key factor affecting fresh-water snail transmission.This study predicted potential risk of colonization of B.globosus in the mainland of China under climate change.Methods: We investigated minimum and maximum temperatures for B.globosus eggs,juveniles and adult snails kept under laboratory conditions to find the most suitable range by pinpointing the median effective temperatures(ET50).We also assessed the influence of temperature on spawning and estimated the accumulated temperature(AT).The average air temperatures between 1955 and 2019 in January and July,the coldest and hottest months in China,respectively,were collected from national meteorological monitoring stations and investigated in a geographic information system(GIS)using empirical Bayesian Kriging to evaluate the theoretical possibility for distribution of B.globosus in southern China based on temperature.Results: The effective minimum temperature(ET50min)for eggs,juveniles,adult snails and spawning were 8.5,7.0,7.0,14.9℃,respectively,with the corresponding maximum values(ET50max)of 36.6,40.5,40.2 and 38.1℃.The AT was calculated at 712.1±64.9℃·d.In 1955,the potential B.globosus distribution would have had a northern boundary stretching from the coastal areas of Guangdong Province and Guangxi Autonomous Region to southern Yunnan Province.Since then,this line has gradually moved northward.Conclusions: Annual regeneration of B.globosus can be supported by the current climate conditions in the mainland of China,and a gradual expansion trend from south to north is shown in the study from 2015 to 2019.Thus,there is a potential risk of colonization of B.globosus in the mainland of China under climate change. | Xinyao Wang Saleh Juma Wei Li Mchanga Suleman Mtumweni Ali Muhsin Jian He Mingzhen He Dacheng Xu Jianfeng Zhang Robert Bergquist Kun Yang | 2022 | Infectious Diseases of Poverty2022，11，3： | 0 |
