Abstract

To understand the infection of intestinal parasites in children in Baoshan area, especially the prevalence of opportunistic protozoa and zoonotic parasites, from October 2007 to May 2008, 8 villages and towns in Baoshan area were surveyed. Using Lugol's iodine staining, saturated sucrose solution floating, modified acid-fast staining and molecular biology method, 1949 children under 15 years of age were surveyed in 23 investigation points of Linzhou area. The total infective rate of parasite was 1.33% (26/1949). Six kinds of intestinal parasites were found, of which three were parasitic and worm, the infection rates were 0.72% and 0.62% respectively. The infection rates of males and females were 1.27% (14/1103) and 1.42% (12/846) respectively, with no significant difference (P> 0.05). The infection rates of children in Yaocun, Chengjiao, Chaandian, Linqi, Wulong, Dongyao, Hengshui and Jinsang were 1.76%, 1.42% and 0.83% respectively. 71%, 0.00%, 0.74%, 1.45%, 0.75% and 1.33%, respectively. There was no significant difference in the infection rates among towns (P> 0.05). For the first time, to find out the prevalence of children infected with Cryptosporidium in Baoshan area, the infection rate was 0.15%. One isolate of Carnosoma was molecularly identified, and the sequence analysis showed that Atoxoplasma sp. (AY331571) was the closest, homology reached 99.4%, indicating that the intestinal parasitic infection may be caused by bird fecal contamination. The prevalence of intestinal parasites in Baoshan area is low, but health education should be further popularized, health knowledge should be popularized, self-care awareness and self-care ability should be improved, and the occurrence and prevalence of parasitic diseases should be prevented.
