The present paper describes the ultrastructure of the surface topography, head organ, tegument, musculature, glandular system, primary alimentary tract and flame cells of the Chinese mainland strain of Schistosoma japonicum cercaria, as visualized with both scanning and transmission electron microscopes. The results not only illustrate the morphological features of the cercarial surface and its...

A species-specific quantitative PCR (qPCR) assay was combined with two novel water-sampling methods and compared with the mouse bioassay for the quantitative detection of S. japonicum in surface waters. The novel methods were capable of capturing cercariae and, with subsequent analysis through qPCR, detecting the presence of a minimum of 1 cercaria.

Introduction Lymnaea gedrosiana snails are hosts to a variety of trematode cercaria public and veterinary health importance. In Guilan Province, Iran, region with high level fish bird farming wetlands important for migratory birds, little is known about the from L. . Methods From April 2020 October 2021, six freshwater sites in Province were sampled Lymnaeidae three times per season (spring, su...

overall 10389 snails were collected from four study areas of punjab from november 2005 to october2006. the highest prevalence (38%) was found for indoplanorbis followed by physa (17%), bellamaya(10.3%), gyraulus (10%), lymnaea (9.2%), oncomelania (9%) and the lowest was found for bulinus (6.7%).only indoplanorbis snails were found to be positive for schistosoma bovis cercaria. correlation betwe...

Spontaneous electrical activity is recorded in two species of marine cercariae, Cryptocotyle lingua and Himasthla elongata, with different types of swimming-by glass microelectrode recordings. Slow local field potentials (sLFPs) of low amplitude and fast high amplitude action potentials (APs) are found. The shape of the sLFPs is different in the species and correlates with the type of swimming....

The body wall of the cercaria of Schistosoma japonicum is covered with a thin integument which is connected to epithel cells located under the uscle layer. On the outer and the basal surfaces of the integument are seen thin limiting membranes. In the matrix of the integument are distributed numerous dense granules, vacuoles and spines. The rootlet of the spine is attached to the basement membra...

objective: lymnaea palustris was previously found in mazandaran province but there was not any report about its parasitologic aspects. this study was conducted to finding ecological and parasitological aspects of snail in mazandaran province, north of iran. materials and methods: in this descriptive study, more than 181 locations, were checked, in 36 locations, colonies of the snail were found...
