Non-invasive immunodiagnosis of Schistosomiasis japonica: the detection of specific antibodies in saliva / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To assess the feasibility of using saliva for Schistosomiasis japonica diagnosis.</p><p><b>METHODS</b>Schistosoma japonicum infected animal model was established. Pairs of saliva and serum samples from rabbits and chronic schistosomiasis patients were collected. Anti-schistosoma specific antibodies in saliva and serum were detected by indirect ELISA.</p><p><b>RESULTS</b>The specificities of antibody detection of rabbit saliva and serum were 93% (28/30) and 97% (29/30), respectively, and the sensitivities of antibody detection of rabbit serum and saliva were 100% (24/24) and 88% (21/24), respectively. A significant correlation (r = 0.5307, P = 0.0038 < 0.05) existed between anti-SEA IgG levels in serum and saliva. As with those in serum, anti-SEA IgG levels in saliva could reflect the state of infection and treatment. The sensitivity of antibody detection was 91% (29/32) for patient saliva samples and 100% (32/32) for their sera. 8 samples were positive in 140 normal saliva samples (i.e. 6% false positive rate) and 6 samples were positive in 156 normal serum samples (4% false positive rate). There was a significant correlation (r = 0.4227, P = 0.008 < 0.05) between specific antibodies in saliva and serum.</p><p><b>CONCLUSION</b>The detection of specific antibodies in saliva can be used as a non-invasive immunodiagnosis method of Schistosomiasis japonica.</p>

Effect of Ecological Treatment by Musca domestica Larvae to Pig Manure on the Oviposition and Larvae Hatching Rate / 中国寄生虫学与寄生虫病杂志

Objective To observe the change of housefly (Musca domestica) breeding in the pig manure treated ecologically with its larvae. Methods The number of eggs and the hatching rate of larvae in the treated manure were compared with that in the untreated manure. Results The number of eggs laid in the treated manure accounted for only 17
