A new echinostome cercaria, Cercaria kuwaitae XI sp.n., from the prosobranch gastropod Cerithidea cingulata (Gmelin) from Kuwait Bay is described. The new cercaria is characterized by 23 collar spines and primary excretory tubules with distinct diverticula. The cercaria encysts in the snail host and is similar to those of Acanthoparyphium sp. The surface topography of the redia, cercaria and me...

Trematode cercariae are commonly found in many freshwater gastropods. These cercariae can serve to identify the occurrence of such trematodes as Centrocestus formosanus, Haplorchis taichui, Haplorchoides sp, and Stellantchasmus falcatus, which are important parasites in Chiang Mai Province, Thailand. As the species of these cercariae cannot be identified accurately based on morphology, this stu...

Schistosoma japonicum (S. japonicum) is a worldwide spread pathogen which penetrates host skin and then induces several diseases in infected host, such as fibrosis, formation of granulomas, hepatocirrhosis, and hepatomegaly. In present study, for the first time, transcriptomic profiles of mouse livers and skins infected by fork-tailed S. japonicum cercaria or non-fork-tailed S. japonicum cercar...

penetration of the cercaria. It was known for more than ten years by tha name of•gKogan Byo•h(lake side disease) along side Lake Shinji in Shimane Prefecture. According to Tanabe (1951), Cercaria sturniae is the larval form of Giganlobilharzia sturniae Tanabe, 1951, infesting usually in the vein of Sturnia philippensis (Forster) and its first intermediate host being Segmenti na ni ti dell a (Po...

A total of 909 Biomphalaria tenagophila were collected from two areas in Guarulhos (Metropolitan area of São Paulo, São Paulo State, Brazil) to assess larval trematode infections. In all collection sites, only this species was found and 183 (20.13%) harbored trematode infections. In these collections, four morphologically distinguishable types of cercariae were identified by confocal microscopy...

A food-borne trematode infection fascioliasis is one among common public health problems worldwide. It caused a great economic loss for the human race. Control of snail population below a certain threshold level is one of the important methods in the campaign to reduce the incidence of fascioliasis. The life cycle of the parasite can be interrupted by killing the snail or Fasciola larva redia a...

plete. Following these reports, Yoshida (1917)(16) made a more detailed description of this cercaria which is called •gCercaria F•h by him, obtained in various areas in Japan, and Cort and Nichols (1920)(3) named it Cercaria yoshidae. During the past few years the author have recovered many Semi sulcospira spp, in various areas in Japan, some of which are from the same spots where Yoshida has c...

The present paper reports three new echinostome cercariae with a review of known 18 spp. of Japanese echinostome cercariae. They were found from the brackish water snails collected from a muddy seashore at Urayasu during the past years from 1944 to 1952. One of these, Cercaria pseudo grani f era n. sp., bearing a strong resemblance to Cercaria grani f era Ogata, 1943, differed from it in detail...

OBJECTIVE To detect the species of larval trematodes (cercariae) in Melanopsis praemorsa snails from 5 different fresh water bodies in Palestine. METHODS A total of 1 880 Melanopsis praemorsa snails were collected from different fresh water bodies in Palestine from October, 2008 to November, 2010. Cercariae in Melanopsis praemorsa snails were obtained by lighting and crushing methods. The beh...

Fasciolosis is a food borne zoonosis, caused by the digenetic trematode Fasciola. Freshwater lymnaeid snails are the intermediate host of the trematodes. Chlorophyllin, a semi-synthetic derivative of chlorophyll and its formulations obtained from freeze dried cow urine (FCU) had their toxicity tested against redia and cercaria larvae of F. gigantica. The larvicidal activity of chlorophyllin and...
