June 2019
Article Synopsis
- The study aimed to analyze the changes in intestinal parasitic diseases in Jiangxi Province from 1989 to 2014 to inform prevention strategies.
- Data was collected from national surveys in 1989 and 2014, revealing an 87.89% decline in the prevalence of human intestinal parasites, from 79.59% to 9.64%.
- The findings showed that while the number of parasite species decreased, soil-transmitted nematodes remained the most common parasites, with higher prevalence rates in females across all age groups.
Soil transmitted helminths (STHs) burden was enormous in China several decades ago, however, rigorous control efforts have been successful with appreciable reduction in diseases burden. Here, we assessed provincial-level data derived from cross sectional surveys, executed in 1989, 2002 and 2014, on the prevalence of STHs among populations in Jiangxi province, China. This study, also, reported STHs integrated control intervention aimed at reducing STHs transmission and worm burden among population at county-level.

[Preservation of live eggs of Schistosoma japonicum].
Zhongguo Xue Xi Chong Bing Fang Zhi Za Zhi
October 2015
Article Synopsis
- - The study aimed to find the best preservation conditions for schistosome eggs to improve quality control for hatching tests by observing the hatching rates and activity of the resulting miracidia over time.
- - Schistosome eggs were collected from infected rabbits and preserved in various solutions at two temperatures (4 °C and 15 °C), with hatching rates monitored at 7-day intervals for up to 280 days.
- - Results indicated that Mili-Q water at 4 °C was the most effective preservation method, maintaining a hatching rate below 10% for 196 days, while other solutions showed significantly lower viability much sooner.
