Flagellum assembly in protozoan parasites
The cell cycle is fundamental for Leishmania survivability and to maintain pathogenicity, ensuring that each generation retains the same cytoskeletal morphology and organelles. This requires a tightly coordinated process of organelle duplication and segregation at specific stages. Using volume …

Studies on protozoan parasites of small mammals
Studies on several different protozoan parasites of small mammals,moles (Talpa europaea), bank voles (Clethrionomys glareolus), fieldvoles (Microtus agrestis), field mice (Apodemus sylvaticus), mice,rats and rabbits are described in this study.In the mole (Talpa europaea) three parasites were …

Transcript Diversity In The Protozoan Parasite Toxoplasma Gondii
… of mRNA-seq data from the obligate intracellular protozoan parasite Toxoplasma gondii, a ubiquitous pathogen of humans and other vertebrates. We produced and sequenced 24 strand-specific RNA libraries from several parasite strains and developmental stages, and examined these in conjunction with 45 …

Mining the Genetic Diversity of the Pathogenic Protozoan, Neospora caninum
𝘕𝘦𝘰𝘴𝘱𝘰𝘳𝘢 𝘤𝘢𝘯𝘪𝘯𝘶𝘮 is a cyst-forming apicomplexan parasite, responsible for economic and reproductive losses to cattle industries worldwide, and represents a serious neurological disease in canines. Although discovered over three decades ago, progress towards treatment and control strategies against …

New Chemotherapeutic Approaches for the Treatment of Parasitic Protozoan Diseases
… approaches for the treatment of parasitic protozoan diseases. The work presented in this thesis focuses on the design, synthesis, and screening (in vitro and in vivo) of bisphosphonates as a novel class of anti-parasitic agents. The infectious agents targeted in this study are Trypanosoma …

Helminth, protozoan and viral infections of the European eel, Anguilla anguilla
… sites.To examine eel for infection with the protozoan haemoflagellate Trypanosomagranulosum, a nested PCR assay was developed to amplify a region of the parasite 18S rRNAgene from heart tissue. Giemsa staining of eel blood sampled from specimens obtained theriver Gowy confirmed the robustness …

Protozoan communities, macrophyte vegetation and trophic status of northern Michigan wetland lakes
… was the first study to simultaneously sample protozoan communities, macrophyte vegetation, water chemistry and nutrient status, and primary productivity of the phytoplankton in each of the four major types of wetlands -- bogs, fens, marshes, and swamps. The following hypotheses were supported …

Protozoan, helminth and arthropod parasites of the gray squirrel in southwestern Virginia
A comprehensive. qualitative and quantitative survey of parasites of 176 gray squirrels. Sciurus carolinensis pennsylvanicus, Ord. 1815, was conducted from September, 1966, to July, 1969, in southwestern Virginia. Most of the hosts came from Montgomery County, some being taken also from Giles and …

Influence of protozoan grazing on the marine geochemistry of particle reactive trace metals
Planktonic protozoan grazers have the potential to significantly affect the chemistry of particle-associated trace metals. This is due both to the importance of protists as consumers of bacterial-sized particles, and to the unique low-pH, enzyme-rich microenvironment of the grazer food vacuole. …

Benthic protozoan community attributes in relation to environmental gradients in the Arabian Sea
“Live” (stained) and dead macrofaunal (>300 ?m fraction) foraminifera in multicorer samples (0-1 cm and 0-5 cm layers) were analysed at six stations along a transect (100-3400 m water depth) across the Oman margin (Arabian Sea) oxygen minimum zone (OMZ). Very high abundances (2858 per 25.5 cm2), …
