Journal of Academia and Industrial Research (JAIR) Volume 3, Issue 3 August 2014 139 ISSN: 2278-5213 RESEARCH ARTICLE Protozoan Fauna of Freshwater Habitats in South Dum Dum Municipality, North 24 Parganas, West Bengal J. Chitra Protozoology Section, Lower Invertebrate Division, M Block, New Alipore, Kolkata-700053, India [email protected]; +91 98315 47265 ______________________________________________________________________________________________ Abstract Wetlands of South Dum Dum Municipality were focused to reveal the status of the planktonic protozoan fauna in detail. A total of 37 different sites were selected and plankton samples from these sites were collected. About 16 sp. of protozoa were identified from few localities from the present investigation. Eight species of rhizopoda belonged to 4 genera, 4 family (Pelomyxidae, Arcellidae, Centropyxidae and Difflugiidae) and 2 order (Pelobintida and Arcellinida), Four species of flagellate belongs to 2 genera, 1 family (Euglinidae) and 1 order (Euglenida), 4 species of ciliate belongs to 4 genera, 4 family (Colepidae, Vorticellidae, Euplotidae and Paramaeciidae), 2 order (Prorodontida and Peritrichida) and 2 suborder (Sporadotrichinia and Peniculina). Among 37 localities, protozoans were observed only in L2, L3, L8, L9, L12, L13, L15, L17, L18, L19, L21, L24, L26, L32, L33, L34 and L36 localities. Protozoan diversity and their abundance were noticed higher in L12, L18, L21, L26, L33 and L34 localities. Euglena viridis, E. acus, E. oxyuris and Phacus acumininata, Pelomyxa palustris, Vorticella companula were found to be higher in abundance and distribution. Keywords: South Dum Dum municipality, planktonic protozoan, Euglena viridis, abundance, distribution. Introduction Dumdum Park, Amarpalli, Telipukur, Nager Bazar, Protozoa are highly abundant in all aquatic habitats and Patipukur and Dum Dum were selected and the plankton greatly involved in food chain (Finlay, 1997). -

Testate amoebae in Vietnam are still poorly investigated. We studied species composition of testate amoebae in 47 waterbodies of South Vietnam provinces including natural lakes, reservoirs, wetlands, rivers, and irrigation channels. A total of 109 species and subspe- cies belonging to 16 genera, 9 families were identified from 191 samples. Thirty-five species and subspecies were observed in Vietnam for the first time. New speciesDifflugia vietnamica sp. nov. is described. The most species-rich genera are Difflugia (46 taxa), Arcella (25) and Centropyxis (14). Centropyxis aculeata was the most common species (observed in 68.1% samples). Centropyxis aerophila sphagniсola, Arcella discoides, Difflugia schurmanni and Lesquereusia modesta were characterised by a frequency of occurrence >20%. Other spe- cies were rarer. The species accumulation curve based on the entire dataset of this work was unsaturated and well fitted by equation S = 19.46N0.33. Species richness per sample in natural lakes and wetlands were significantly higher than that of rivers (p < 0.001). The result of the Spearman rank test shows weak or statistically insignificant relationships between species richness and water temperature, pH, dissolved oxygen, and electrical conductivity. -

The Intestinal Protozoa
The Intestinal Protozoa A. Introduction 1. The Phylum Protozoa is classified into four major subdivisions according to the methods of locomotion and reproduction. a. The amoebae (Superclass Sarcodina, Class Rhizopodea move by means of pseudopodia and reproduce exclusively by asexual binary division. b. The flagellates (Superclass Mastigophora, Class Zoomasitgophorea) typically move by long, whiplike flagella and reproduce by binary fission. c. The ciliates (Subphylum Ciliophora, Class Ciliata) are propelled by rows of cilia that beat with a synchronized wavelike motion. d. The sporozoans (Subphylum Sporozoa) lack specialized organelles of motility but have a unique type of life cycle, alternating between sexual and asexual reproductive cycles (alternation of generations). e. Number of species - there are about 45,000 protozoan species; around 8000 are parasitic, and around 25 species are important to humans. 2. Diagnosis - must learn to differentiate between the harmless and the medically important. This is most often based upon the morphology of respective organisms. 3. Transmission - mostly person-to-person, via fecal-oral route; fecally contaminated food or water important (organisms remain viable for around 30 days in cool moist environment with few bacteria; other means of transmission include sexual, insects, animals (zoonoses). B. Structures 1. trophozoite - the motile vegetative stage; multiplies via binary fission; colonizes host. 2. cyst - the inactive, non-motile, infective stage; survives the environment due to the presence of a cyst wall. 3. nuclear structure - important in the identification of organisms and species differentiation. 4. diagnostic features a. size - helpful in identifying organisms; must have calibrated objectives on the microscope in order to measure accurately. -

Heterotrophic ¯ Agellates (Protista) from Marine Sediments of Botany Bay, Australia
Journal of Natural History, 2000, 34, 483± 562 Heterotrophic ¯ agellates (Protista) from marine sediments of Botany Bay, Australia WON JE LEE and DAVID J. PATTERSON School of Biological Sciences, University of Sydney, NSW 2006, Australia; e-mail: [email protected] (Accepted 19 April 1999) Heterotrophic¯ agellates (protozoa) occurring in the marine sediments at Botany Bay, Australia are reported. Among the 87 species from 43 genera encountered in this survey are 13 new taxa: Cercomonas granulatus n. sp., Clautriavia cavus n. sp., Heteronema larseni n. sp., Notosolenus adamas n. sp., Notosolenus brothernis n. sp., Notosolenus hemicircularis n. sp., Notosolenus lashue n. sp., Notosolenus pyriforme n. sp., Petalomonas intortus n. sp., Petalomonas iugosus n. sp., Petalomonas labrum n. sp., Petalomonas planus n. sp. and Petalomonas virgatus n. sp.; and seven new combinations, Carpediemonas bialata n. comb., Dinema platysomum n. comb., Petalomonas calycimonoides nom. nov., Petalomonas chris- teni nom. nov., Petalomonas physaloides n. comb., Petalomonas quinquecarinata n. comb. and Petalomonas spinifera n. comb. Most ¯ agellates described here appear to be cosmopolitan.We are unable to assess if the new species are endemic because of the lack of intensive studies elsewhere. Keywords: Biogeography, endemic biota, heterotrophic ¯ agellates, taxonomy, protists. Introduction Marine heterotrophic protists are predators on bacteria and small phytoplankton, are prey for larger zooplankton, and facilitate remineralization and recycling of elements essential for phytoplankton and microbial growth (Azam et al., 1983; Porter et al., 1985; Sherr and Sherr, 1988; JuÈ rgens and GuÈ de, 1990; Kirchman, 1994; Pace and Vaque , 1994). Consequently, the role of heterotrophic protists in planktonic microbial food webs of marine environments has received increasing attention. -
Wildlife Parasitology in Australia: Past, Present and Future
CSIRO PUBLISHING Australian Journal of Zoology, 2018, 66, 286–305 Review https://doi.org/10.1071/ZO19017 Wildlife parasitology in Australia: past, present and future David M. Spratt A,C and Ian Beveridge B AAustralian National Wildlife Collection, National Research Collections Australia, CSIRO, GPO Box 1700, Canberra, ACT 2601, Australia. BVeterinary Clinical Centre, Faculty of Veterinary and Agricultural Sciences, University of Melbourne, Werribee, Vic. 3030, Australia. CCorresponding author. Email: [email protected] Abstract. Wildlife parasitology is a highly diverse area of research encompassing many fields including taxonomy, ecology, pathology and epidemiology, and with participants from extremely disparate scientific fields. In addition, the organisms studied are highly dissimilar, ranging from platyhelminths, nematodes and acanthocephalans to insects, arachnids, crustaceans and protists. This review of the parasites of wildlife in Australia highlights the advances made to date, focussing on the work, interests and major findings of researchers over the years and identifies current significant gaps that exist in our understanding. The review is divided into three sections covering protist, helminth and arthropod parasites. The challenge to document the diversity of parasites in Australia continues at a traditional level but the advent of molecular methods has heightened the significance of this issue. Modern methods are providing an avenue for major advances in documenting and restructuring the phylogeny of protistan parasites in particular, while facilitating the recognition of species complexes in helminth taxa previously defined by traditional morphological methods. The life cycles, ecology and general biology of most parasites of wildlife in Australia are extremely poorly understood. While the phylogenetic origins of the Australian vertebrate fauna are complex, so too are the likely origins of their parasites, which do not necessarily mirror those of their hosts. -

Protist Phylogeny and the High-Level Classification of Protozoa
Europ. J. Protistol. 39, 338–348 (2003) © Urban & Fischer Verlag http://www.urbanfischer.de/journals/ejp Protist phylogeny and the high-level classification of Protozoa Thomas Cavalier-Smith Department of Zoology, University of Oxford, South Parks Road, Oxford, OX1 3PS, UK; E-mail: [email protected] Received 1 September 2003; 29 September 2003. Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane). -
