The Southeast Asian Journal of Tropical Medicine and Public Health. 1998 Mar; 29(1): 128-30http://imsear.searo.who.int/handle/123456789/30562The Southeast Asian Journal of Tropical Medicine and Public Health.An improved laboratory method was developed for counting Schistosoma japonicum eggs in pig feces, which involves filtration, sedimentation and centrifugation, but avoids toxic chemicals. It is sensitive, allows easy differentiation from similar-sized and shaped protozoan cysts, and permits evaluation of egg viability both by direct viewing of eggs and miracidial hatching. It was found to be significantly better at recovering eggs than the modified Bell filtration technic. The sensitivity, specificity and practicality of this technic make it our method of choice for studies on porcine schistosomiasis japonica.engAnimalsFeces --parasitologyParasite Egg Count --methodsSchistosoma japonicumSchistosomiasis japonica --parasitologySwine --parasitologySwine Diseases --parasitologyA new technic for counting Schistosoma japonicum eggs in pig feces.Journal Article
