Morphometric study of a Brazilian strain of Carchesium polypinum (Ciliophora: Peritrichia) attached to Pomacea figulina (Mollusca: Gastropoda), with notes on a high infestation

Phylogenomic analyses reveal subclass Scuticociliatia as the sister group of subclass Hymenostomatia within class Oligohymenophorea

“…Each population was isolated in the laboratory using ophthalmological scissors and tweezers, and then picked out using dissecting needles and glass micropipettes. Campanella umbellaria and Carchesium polypinum were morphologically identified according to previous 6 / 25 reports (Dias et al, 2010;Foissner, 1992;Shi et al, 2004). The infraciliatures of the two species were revealed by protargol staining according to the method of Shi and Frankel (1990).…”

Two Newly Recorded Vorticellid Species (Ciliophora, Oligohymenophorea, Peritrichia) from Jindo Island with Other Populations in Korea

“…Classification and terminology follows Lynn (2008) and Ji et al (2015). : Ehrenberg, 1830: 41;Stein, 1854: 78;Kahl, 1935: 738;Foissner and Schiffmann, 1974: 491, 504;Esteban and Fernández-Galiano, 1989: 345;Foissner et al, 1992: 137;Shi et al, 2001: 13;Dias et al, 2010: 483.…”

“…The Chinese population was also different to the two Korean populations in the adjoined part of infundibular polykinety 1 and 3 (shorter vs. longer) (Shi et al, 2001). The Brazilian (São Pedro stream) population was different to the two Korean populations in the habitat (epizoic vs. benthic vs. benthic) and the length of zooid (70-110 μm vs. 51-140 μm) (Dias et al, 2010 Figs. 3, 4) Vorticella campanula Ehrenberg, 1831: 92;1838: 272;Noland and Finley, 1931: 105;Foissner and Schiffmann, 1974: 500;Warren, 1986: 55;Foissner et al, 1992: 105;Shi et al, 2003: 64;Qi and Shi, 2008: 9081. Description.…”

“…According to Gentekaki and Lynn (2010), Carchesium polypinum complex might be firstly described by Leeuwenhoek in 1676 and Linnaeus (1758) officially described. Thereafter, many researchers redescribed C. polypinum (Esteban and Fernán-dez-Galiano, 1989;Foissner et al, 1992;Shi et al, 2001;Dias et al, 2010). However, populations of C. carchesium had enormous amount of genetic differences but could not distinguishable based on the morphology.…”

Ciliated microeukaryotes (Alveolata: Ciliophora) of a lotic urban system located in Minas Gerais - Brazil

“…The access to ciliate diversity and biogeography is a challenge tasks because they are diminute organisms, difficult to identify (Finlay and Fenchel, 1999), there is a lack of experienced specialists (Foissner, 2006) and a number of species stay encysted for most of their life cycles (Foissner, 2004). In Brazil, significant works were performed with this emphasis such as conducted in Rio Grande do Sul (Safi et al, 2014), Paraná (Pauleto et al, 2009;Buosi et al, 2011;Velho et al, 2005Velho et al, , 2013, São Paulo (Bagantini et al, 2013;Regali-Seleghim et al, 2011), Pará (Castro et al, 2014), Minas Gerais (Dias et al, 2008(Dias et al, , 2010 and Rio de Janeiro (Paiva and Silva-Neto, 2004a, b) states. Inventory studies constitute the first step for development of applied biotechnological usage of ciliates.…”
