Ensaio monográfico da familia Cyathodiniidae
Memorias do Instituto Oswaldo Cruz, 1940 1) Os Cyathodiniidae são ciliados caracterisados morfologicamente pela existência de uma escavação de abertura antero-ventral, o pseudo-peristoma. A ciliatura é constituída por cilios uniformes dispostos em linhas transversas ou obliquas que revestem a ...

“Candidatus Trichorickettsia mobilis”, a Rickettsiales bacterium, can be transiently transferred from the unicellular eukaryote Paramecium to the planarian Dugesia japonica [PDF]
PeerJ, 2020 Most of the microorganisms responsible for vector-borne diseases (VBD) have hematophagous arthropods as vector/reservoir. Recently, many new species of microorganisms phylogenetically related to agents of VBD were found in a variety of aquatic eukaryotic

Journal of Fish Diseases, Volume 49, Issue 3, March 2026.Abstract This case report presents a recent case of scuticociliatosis in a whitetip reef shark (Triaenodon obesus), housed at a zoo (Haus des Meeres Aqua Terra Zoo, Vienna, Austria). Clinical signs such as uncoordinated swimming and body tilt were observed prior to death.

The Macronucleus of Spirostomum
Nature, 1958 THE purpose of this communication is to describe an interesting property of the macronucleus of a species of Spirostomum, a large freshwater ciliate. The nuclear apparatus of this animal consists of a long cylindrical macronucleus and a number of small micronuclei. The cytology of this species has been described by Seshachar and Padmavathi1.

Progeny of Germ Line Knockouts of \u3cem\u3eASI2\u3c/em\u3e, a Gene Encoding a Putative Signal Transduction Receptor in \u3cem\u3eTetrahymena Thermophila\u3c/em\u3e, Fail to Make the Transition from Sexual Reproduction to Vegetative Growth [PDF]
, 2006 The ciliated protozoan Tetrahymena has two nuclei: a germ line micronucleus and a somatic macronucleus. The transcriptionally active macronucleus has about 50 copies of each chromosome.

Pulmonary cytology: Pearls and pitfalls of non‐neoplastic mimics of lung cancer
Cancer Cytopathology, Volume 133, Issue 9, September 2025.Abstract Lung cancer continues to be the leading cause of cancer‐related mortality, with cytologic samples often serving as the primary diagnostic tool. However, differentiating between benign and malignant processes in lung cytology can be difficult because various non‐neoplastic conditions closely resemble malignant lesions, which may lead to ...

BMC Genomics, 2017 Background DNA elimination is developmentally programmed in a wide variety of eukaryotes, including unicellular ciliates, and leads to the generation of distinct germline and somatic genomes. The ciliate Paramecium tetraurelia harbors two types of nuclei
