The process of gene unscrambling in hypotrichous ciliates represents one of nature's ingenious solutions to the problem of gene assembly. With some essential genes scrambled in as many as 51 pieces, these ciliates rely on sequence and structural cues to rebuild their fragmented genes and genomes. Here we report the complex pattern of scrambling in the DNA polymerase alpha gene of Stylonychia le...

Pheromone 3 mRNA of the ciliate Euplotes octocarinatus contains three in-frame UGA codons that are translated as cysteines. This was revealed from cDNA sequencing and from plasma desorption mass spectrometry of cleaved pheromone 3 in connection with pyridylethylation of the fragments. N-terminal sequence analysis of carboxymethylated protein confirmed this conclusion for the first of the three ...

Gene assembly in stichotrichous ciliates happening during sexual reproduction is one of the most involved DNA manipulation processes occurring in biology. This biological process is of high interest from the computational and mathematical points of view due to its close analogy with such concepts and notions in theoretical computer science as permutation and linked list sorting and string rewri...

In the sample of 83 specimens of the perch (Perca fluviatilis L., 1758), caught on eight different sampling sites at the Vlasinsko Lake reservoir, in April–October 1993, 25 infested specimens were found. They were infested with the following species of parasitic ciliates: Trichodinella epizootica, Apiosoma robustum, Apiosoma piscicolum ssp. perci, Ichthyophthirius multifiliis, Chilodonella cypr...

Abstract The Western Antarctic Peninsula (WAP) is experiencing rapid climate warming, resulting in affecting the marine food web. To investigate microzooplankton spatial distribution and to assess how change could affect tintinnids community, sea water samples were collected during late summer 2018 at 19 stations three different areas: Deception Island, Elephant Island Sound. community comprise...

In the study of biodiversity, there are some challenges that are unique to each taxonomic group, such as which characters should be evaluated when describing species. There are also broad challenges that are applicable to all groups, such as how to make biodiversity data accessible to other researchers. To discuss and pave the way to solving these broad challenges within the ciliates—as well as...

Background: Treatment and wastewater disposal lack in Abidjan leads to discharge the natural environment without treatment. These waters were loaded with pathogenic microorganisms that are causes of many diseases. Objectives: This study aims assess parasitological quality water from pipes Abididjan City, studying protozoa helminths. Methodology: 400 samples collected three municipalities 19 sit...
