To assess the impact level on physical fitness and working capacity in patients with advanced Schistosomiasis japonica, a field study was carried out. According to the records of patients with advanced schistosomiasis in Susong County, Anhui Province, 48 advanced cases without other serious chronic diseases from endemic areas in two townships and 56 healthy(More)
Schistosoma japonicum remains highly endemic in many counties in China and has recently re-emerged, to a large extent, in previously controlled areas. To test the hypothesis that small rodents and less agriculturally important domestic animals such as dogs and cats may play an important role in the transmission and potential re-emergence of this disease, an(More)
The transmission dynamics of Schistosoma japonicum remain poorly understood, as over forty species of mammals are suspected of serving as reservoir hosts. However, knowledge of the population genetic structure and of the full-sibship structuring of parasites at two larval stages will be useful in defining and tracking the transmission pattern between(More)
Schistosoma japonicum, a parasite of significant public health importance in parts of China and Southeast Asia, is a true generalist pathogen with over 40 species of mammals suspected as definitive host reservoirs. In order to characterize levels of parasite gene flow across host species and identify the most important zoonotic reservoirs, S. japonicum(More)
Understanding disease transmission dynamics in multihost parasite systems is a research priority for control and potential elimination of many infectious diseases. In China, despite decades of multifaceted control efforts against schistosomiasis, the indirectly transmitted helminth Schistosoma japonicum remains endemic, partly because of the presence of(More)
OBJECTIVE To understand the dynamic changes of the potential prevalent factors of schistosomiasis in Chaohu Lake area so as to provide forecast information on the outbreak of schistosomiasis in the area. METHODS From 2008 to 2010, fixed and mobile surveillance sites in potential endemic areas of Juchao District in Chaohu City, which was located in the(More)
OBJECTIVE To investigate the possibility of spread of snails and transmission of schistosomiasis japonica due to the construction of water transfer project from Yangtze River to Huaihe River. METHODS In order to understand the current endemic situation of schistosomiasis in the project area, the distribution of snails was surveyed by routine methods,(More)
Schistosoma japonicum is an important parasite in terms of clinical, veterinary and socio-economic impacts, and rodents, a long neglected reservoir for the parasite, have recently been found to act as reservoir hosts in some endemic areas of China. Any difference in the host's biological characteristics and/or associated living habitats among rodents may(More)
Schistosomiasis japonica is a disease of profound medical and veterinary importance which has remained endemic in many regions and has re-emerged where previously controlled in China. Although over 40 mammalian species are suspected as reservoirs for Schistosoma japonicum, their relative roles, particularly wildlife, remain to be ascertained. As cercarial(More)
