The mature domain of a cysteine protease of Spirometra erinacei plerocercoid larva (i.e., sparganum) was expressed in Escherichia coli, and its value as an antigen for the serodiagnosis of sparganosis was investigated. The recombinant protein (rSepCp-1) has the molecular weight of 23.4 kDa, and strongly reacted with the sparganum positive human or mice sera but not with negative sera by immunob...

Ultrastructural characteristics of progenetic and monoxenic Archigetes sieboldi Leuckart, 1878 from the oligochaete Limnodrilus hoffmeisteri Claparède are described. Our observations demonstrate that progenetic Archigetes sieboldi shares characteristics of both larval (progenetic) and adult stages. The primary larval characteristics are: the presence of a cercomer; a surface filamentous coat co...

The infection prevalence of Ligula colymbi plerocercoids in the spined loach Cobitis taenia inhabiting brackish waters of the Baltic Sea, and the effects of the parasite on the reproduction and growth of the host were studied. There was no significant trend in the infection rate among the different sampling dates in May–July. In total, 24.6% of females and 15.4% of males were infected. In most ...

BACKGROUND Sparganosis caused by invasion of the plerocercoid larvae (spargana) of Spirometra erinaceieuropaei have increased in recent years in China. However, the population genetic structure regarding this parasite is still unclear. In this study, we used the sequences of two mitochondrial genes cytochrome b (cytb) and cytochrome c oxidase subunit I (cox1) to analyze genetic variation and ph...

with no adverse effects reported. One patient treated herself with albendazole (400 mg/day for 3 days) before she was seen at a hospital. All patients became asymptomatic and had negative stool examination results 2–10 weeks after treatment. None of the patients reported previous or subsequent consumption of raw freshwater fi sh. Raw fi sh preparations such as sushi, sashimi, carpaccio, and cev...

background : ligulae intestinalis is a parasitic cestode, which has the economic-health importance in fishery industries. the aim of this study was to determine the prevalence of this parasite in mazandaran. the effects of habitat temperature and kind of pool (sandy-cement) were considered as well. methods : in this study, 103 fish samples were obtained in all stages; the samples (male and fema...

IT is generally recognized that glycogen is a very labile substance which disappears rapidly from tissues unless treated by special methods of fixation and embedding. The recognized and widely used techniques, advocated by the standard microtomical treatises, call for fixation in a glycogenprecipitating fixative (absolute alcohol; picro-formol-alcohol; picro-dioxane) followed by celloidin embed...

quaculture of salmon constitutes a rapidly growing worldwide industry with an expanding globalized market (1,2). Although this industry has several economic benefits, according to recent reports it is also accompanied by effects that are detrimental to human and animal health and the environment (1,2). Aquaculture has been implicated in the transmission of infectious diseases. For example, in c...
