Introduced Pathogens and Native Freshwater Biodiversity: A Case Study of Sphaerothecum destruens
A recent threat to European fish diversity was attributed to the association between an intracellular parasite, Sphaerothecum destruens, and a healthy freshwater fish carrier, the invasive Pseudorasbora parva originating from China. The pathogen was found to be responsible for the decline and local extinction of the European endangered cyprinid Leucaspius delineatus and high mortalities in stoc...
متن کاملInfluence of host reproductive state on Sphaerothecum destruens prevalence and infection level.
Sphaerothecum destruens is an obligate intracellular parasite with the potential to cause high mortalities and spawning inhibition in the endangered cyprinid Leucaspius delineatus. We investigated the influence of L. delineatus's reproductive state on the prevalence and infection level of S. destruens. A novel real time quantitative polymerarse chain reaction (qPCR) was developed to determine S...
متن کاملAssociated disease risk from the introduced generalist pathogen Sphaerothecum destruens: management and policy implications
The rosette agent Sphaerothecum destruens is a novel pathogen, which is currently believed to have been introduced into Europe along with the introduction of the invasive fish topmouth gudgeon Pseudorasbora parva (Temminck & Schlegel, 1846). Its close association with P. parva and its wide host species range and associated host mortalities, highlight this parasite as a potential source of disea...
متن کاملHigh prevalence of the parasite Sphaerothecum destruens in the invasive topmouth gudgeon Pseudorasbora parva in the Netherlands, a potential threat to native freshwater fish
The prevalence of Sphaerothecum destruens, a pathogenic parasite, was studied in two wild populations of topmouth gudgeon (Pseudorasbora parva), an invasive freshwater fish non-native to the Netherlands. Using genetic markers and sequencing of the 18S rRNA gene, we showed the prevalence of this parasite to be 67 to 74%. Phylogenetic analysis demonstrated a high similarity with known sequences o...
متن کاملHeterogenous presentation of chorioadenoma destruens.
Invasive mole also known as chorioadenoma destruens comprises about 15 % of all gestational trophoblastic neoplasia [1]. It is a trophoblastic tumor characterized by myometrial invasion by direct extension or through venous channels. The most common presenting symptom is vaginal bleeding (97 %) [2]. The diagnosis is usually suggested after a hydatidiform mole is removed and bhCG remains elevate...
