A commercial indirect hemagglutination (IHA) test using erythrocytes coated with Schistosoma mansoni adult worm antigens (WA) and an enzyme-linked immunosorbent assay (ELISA) with S. mansoni egg antigens (SEA) were assessed for their use in serodiagnosis of imported schistosomiasis (hereafter these tests are designated WA/IHA and SEA/ELISA, respectively). The sensitivity of the tests was evalua...

BACKGROUND Katayama fever is an acute clinical condition characterised by high fever, dry cough and general malaise occurring during early Schistosoma spp. infection. It is predominantly reported in travellers from non-endemic regions. Whereas the immunological response to Schistosoma infection is well characterised, alterations in inflammatory markers and coagulation in response to acute infec...

A morphological and genetic reassessment of the phylogeny and taxonomy of the dwarf zoarcid fish Lycodes teraoi Katayama, 1943 indicated that the species, a senior synonym of Lycodes sadoensis Toyoshima & Honma, 1980, should be placed in the genus Petroschmidtia. A redescription of P. teraoi is provided, with remarks on its taxonomy. Numerous specimens revealed a wide distribution of P. teraoi ...

Even brief visits abroad may bring travellers into contact with pathogens against which they have no immunity. Though returning home apparently well, the travellers may be incubating an exotic illness with which they then present to their local doctor. We report a recent outbreak of acute Schistosoma mansoni infection that occurred in this way.
