Morphometrics of Brazilian strains (BH, SJ and CMO) of Schistosoma mansoni cercariae were obtained with a computerized image analyzer (IMAGE PRO PLUS, MEDIA CYBERNETICS), considering the following characters: body area, tail, furcae, oral and ventral suckers and distance between them. For statistical analysis, the variance test (one-way Anova) was applied and significant differences of p< 0.05 ...

The aim of this study was to determine the presence and prevalence of larval stages of Dicrocoelium dendriticum and Brachylaima sp. in the first intermediate host, a species of land snail, Helix aspersa, in Turkey. A total of 211 snails were collected in April-May 2014 from pastures in Mersin District. Larval stages of D. dendriticum were identified under a light microscope. Hepatopancreas from...

The effect of hydrocortisone on the development of BH strain of S. mansoni in B. glabrata snails is evaluated. Snails in a randomly chosen group were submitted to hydrocortisone during four days. In the second day of hydrocortisone exposure, the snails were exposed, each, to ten S. mansoni miracidia. Another group, not treated with hydrocortisone, was exposed to miracidia and observed in the sa...

Despite decades of prevention and control efforts, the water-borne parasitic disease schistosomiasis remains endemic in 74 of the world’s developing nations. Five species of the Schistosoma trematode are pathogenic to humans; S. japonicum is the infective agent of schistosomiasis in China and the Philippines. The purpose of this research is to develop a sensitive and specific technique for the ...

Schistosoma mansoni is a digenean parasite known for its importance as a human pathogen. Compared with the other genera belonging to the digenean families, the Schistosoma genus is characterized by having acquired gonochorism from hermaphroditic ancestors [1]. Sex is genetically determined in the egg [2] and female schistosome is heterogametic (ZW) such as lepidoptera, reptiles and birds. A mar...

Proterometra epholkos sp. n. asexually reproduces in the stream dwelling prosobranch, Elimia cf. modesta (Cerithioidea: Pleuroceridae) and infects the buccal cavity epithelium of spotted bass, Micropterus punctulatus (Perciformes: Centrarchidae) in the Coosa River (Terrapin Creek; N33°51'36.56″, W85°31'28.15″; Cleburne County, Alabama, USA). We characterize cercariae and adults of the new speci...
