    ABSTRACT: Species of the family Prosthogonimidae are considered the most pathogenic poultry trematodes worldwide, affecting particularly low intensity farming in rural areas. Adults of Prosthogonimus occur mainly in the bursa of Fabricius, oviduct and cloaca of ducks, geese, fowl and other birds feeding at least occasionally on dragonflies or damselflies (Odonata). We analyzed the central European species of the Prosthogonimidae, namely Prosthogonimus cuneatus, P. ovatus, P. pellucidus and P. rarus. We sequenced three nuclear (ITS2) and mitochondrial (CO1, ND1) DNA loci of four species isolated from Anas clypeata, Anas strepera, Anas platyrhynchos, Aythya ferina, Passer domesticus and Turdus merula. Intra- and inter-specific sequence variability revealed that all four species represent distinct well-defined entities. Our data, combined with previously published studies, suggest the return of the name Prosthogonimus rarus Braun, 1901 for Schistogonimus rarus (Braun, 1901). The genus name Schistogonimus Lühe, 1909 is considered a junior synonym of Prosthogonimus Lühe, 1899. We identified the existence of two clades, one represented by P. cuneatus and P. pellucidus, and another one formed by P. ovatus and P. rarus. We also provide comparative measurements of these four central European prosthogonimids, and address their tissue specificity, host-specific prevalence (based on the extensive bird cohort examined in years 1962-2014), and for some bird hosts we address also differences in the prevalence of Prosthogonimus spp. in natural and near-natural wetlands in comparison with fishponds utilized for intense carp production. We provide an updated key to European Prosthogonimus spp. based on their morphological characters. Copyright © 2015. Published by Elsevier Ireland Ltd.

    ABSTRACT: Due to the unprecedented recent increases in global migration, Chagas disease has become a global health threat and its epidemiology has drastically changed. Here we describe the first case in Japan of benznidazole treatment for chronic Chagas disease characterized by advanced cardiac complications. A 55-year-old Japanese-Brazilian woman who had previously presented with chronic heart failure was diagnosed as having Chagas disease and treated with benznidazole to prevent aggravation of her cardiac complications. However, benznidazole administration was stopped on day 56 due to severe drug-induced peripheral neuritis. Sixteen months later, her serologic test for T. cruzi is still positive and she is being followed regularly by cardiology. Despite an estimated prevalence of over 4,000 cases in Japan, only a few cases of Chagas disease have been reported. A Medline search revealed only 7 cases identified between 1995 and 2014 in Japan: in 6 cases, complications of chronic Chagas disease were apparent at the time of presentation, and sudden death occurred in 2 of these cases due to cardiac complications. This clinical case and literature review re-emphasize the urgent need to establish a surveillance network and improve the diagnostic methods and treatment framework for Chagas disease in Japan.

    ABSTRACT: Here we report the genetic variability and presence of mtDNA-like sequences of P. laevis from the chub, Squalius cephalus, caught at the sampling sites along the Sava River and its tributary the Sutla River in Croatia. Sequences of the cytochrome c oxidase subunit 1 (COI) gene of the recovered P. laevis specimens were used for haplotype network construction and phylogenetic analysis. These analyses showed that some specimens contained mitochondrial-like sequences, and they uncovered the existence of a Sava River basin strain different from known strains of P. laevis. This is the first time that P. laevis has been shown to contain mtDNA-like sequences, suggesting the need to exercise caution during COI analyses of P. laevis using universal primers. Highly conserved sequences of two nuclear markers, the ITS region and 18S rRNA, were not helpful for understanding genetic variability or differentiating strains. Furthermore, analysis of the dynamics of P. laevis infections in S. cephalus from the Sava and Sutla Rivers showed decreased prevalence and abundance at sites with inferior water quality, positive association of parasite abundance with fish size, and no clear association of parasite abundance with fish condition index or sex.

    ABSTRACT: Centrocestus formosanus is an intestinal foodborne trematode with medical and veterinary importance that remains with pathological and immunological aspects of the infection in definitive host poorly studied. In the present study, we evaluated effects of pharmacological immunosuppression by glucocorticoids in experimental centrocestiasis. Mice of the AKR/J strain were orally inoculated with 100 metacercariae of C. formosanus obtained in naturally infected fish (Australoheros facetus) collected in an urban reservoir from Brazil. Treatment with dexamethasone (25mg/kg, via subcutaneous injection) was started 1 hour before infection of mice and then continued daily during 14 days post-infection. Untreated mice also infected with C. formosanus were used as control. At the end of the treatment course, all rodents were euthanized and adult parasites recovered from host intestines were subjected to morphological and morphometric analysis under optical microscopy. The worm burden in dexamethasone treated group [70 ± 14 (41–85)] was significantly greater (p < 0.0001) than that in the control group [15 ± 4 (10–22)]. In addition, the parasites recovered from immunosuppressed mice were larger, with more developed reproductive structures and greater number of intrauterine eggs than in control mice. These parasite developmental changes induced by dexamethasone treatment are reported for the first time in experimental centrocestiasis. Moreover the higher parasite fecundity induced by glucocorticoid treatment had so far not been reported for any heterophyid species, which can have implications for the pathology and morbidity in infections caused by these parasites.

    ABSTRACT: Rodent malaria is a useful model for evaluating the efficacy of malaria vaccine candidates; however, labor-intensive microscopic parasite counting hampers the use of an in vivo parasite challenge in high-throughput screening. The measurement of malaria parasite lactate dehydrogenase (pLDH) activity, which is commonly used in the in vitro growth inhibition assay of Plasmodium falciparum, may be the cheapest and simplest alternative to microscopic parasite counting. However, the pLDH assay has not been applied in the in vivo rodent malaria model. Here, we showed that the pLDH assay is reliable and accurately determines parasitemia in the rodent malaria model. pLDH activity measured using a chromogenic substrate reflects the parasite number in the blood; it allows fast and easy assessment using a conventional microplate reader. To validate this approach, we synthesized recombinant PyMSP1-19 protein (rPyMSP1-19) using a wheat germ cell-free protein synthesis system and immunized mice with rPyMSP1-19. The antisera showed specific reactivity on the surface of the P. yoelii merozoite and immunized mice were protected against a lethal P. yoelii 17 XL challenge. The pLDH assay quickly and easily demonstrated a significant reduction of the parasite numbers in the immunized mice. Accordingly, the pLDH assay proved to be an efficient alternative to rodent malaria parasite counting, and may therefore accelerate in vivo vaccine candidate screening. Copyright © 2015.
