Chapter
all about intestinal flagellates
Article
Full-text available
Most of our knowledge on the processes structuring parasite communities in amphibians originate from temperate-zone taxa, whereas Afrotropical communities have been neglected so far. We found evidence that ecological fitting of the hosts and, probably, differential immune response may influence the variation in parasite species richness, prevalence...

All about Leishmaniasis (in German, and comprised)
Article
Full-text available
To perform PCR from serum for the diagnosis of visceral leishmaniasis is convenient and much less invasive than the examination of deeper compartments such as bone marrow. We compared three Leishmania-specific real-time PCRs with three different molecular targets (kinetoplast DNA, the small subunit-ribosomal RNA-(ssrRNA-)gene, the glucose-6-phospha...

Full-text available
The diversity of nematodes infecting amphibians is understudied in tropical Africa and unknown in Rwanda. Diversity assessment is hampered by the fact that species descriptions refer mostly to morphological features that are unlinked to DNA sequences of marker genes available in public databases. In this paper, we explore the abundance and diversit...
Conference Paper
Free-living amoebae (FLA) can be found both in the aquatic environment and in artificial, man-made aquatic environments. As pathogenic microorganisms some strains or species can cause different diseases in humans an animals. The prevalence of FLA in water networks is associated with biofilms, where the amoebae live within a biocoenosis sympatric wi...

Chapter
Free-living amoebae (FLA) are soil- and aquatic-dwelling protozoan microbes ubiquitously found in humid habitats. FLA play an important role in the composition of the microbial flora of water systems and are involved in the formation of biofilm. FLA do not rely on a host for transmission or replication but they are able to live endozoically. In th...
Article
Full-text available
Many case reports emphasize the fact that Free-Living Amoebae (FLA) can relatively easily get in contact with humans or animals. The presence of several facultative parasitic FLA in habitats related to human activities supports their public health relevance. While some strains of Acanthamoeba, Naegleria fowleri , Balamuthia mandrillaris and several...
Article
The helminth endoparasites of many European amphibian species are often exclusively known from morphological descriptions. A molecular library of DNA sequence data linked to morphological identifications is still in its beginnings. We aim to contribute to such a library on the smooth newt Lissotriton vulgaris, the intermediate and definitive host o...

All about Trichomoniasis
Article
Free-living amoebae (FLA) are protozoa ubiquitously found in nature. As some species or strains of these FLA are pathogenic for humans and animals, they represent objects of medical and parasitological research worldwide. Storage of valuable FLA strains in laboratories is often time- and energy-consuming and expensive. The shipment of such strains...
Conference Paper
Free-living amoebae (FLA) can be found both in natural aquatic environments and in artificial, man-made aquatic environments. For a long time, (naked) FLA were considered to be harmless protozoa of soil and water. However, research since the 1960s has demonstrated that FLA can be pathogenic to humans and animals with nearly 100% morbidity from some...

The contact lens storage solution of a patient with keratitis of unknown genesis was screened using our diagnostic tools to detect potentially pathogenic free-living amoebae (FLA). Culture methods and a triplex qua...
Article
Full-text available
As both groups of organisms, free-living amoebae (FLA) and viruses, can be found in aquatic environments side by side, it appears obvious that there are multiple interactions with respect to host-endocytobiont relationships. Several relationships between viruses and protozoan hosts are described and it was the discovery of the so called "giant viru...
