Malaria is caused by Apicomplexa protozoans from the Plasmodium genus entering the bloodstream of humans and animals through the bite of the female mosquitoes. The annotation of the Plasmodium vivax genome revealed a putative RNA binding protein (apiRBP) that was predicted to be trafficked into the apicoplast, a plastid organelle unique to Apicomplexa protozoans. Although a 3D structural model ...

Two ciliate protozoans, Stylonychia mytilus and Paramecium caudatum isolated from tannery effluent and cultured in a medium containing inorganic salts showed tolerance against endosulfan (1.8 μg/ml). The protozoans uptake the insecticide from the medium for utilization. Stylonychia mytilus reduced 21% endosulfan from the medium within 48 hours of inoculation of insecticide containing medium wit...

Prevalence of gastrointestinal parasites was studied in 106 heifers imported to Poland from the Netherlands. Prevalence of gastrointestinal nematodes and Eimeria protozoans was determined from coproscopic examinations using Willis-Schlaf flotation. The species composition of coccidia was determined from morphological characters and the time of oocyst sporulation. Fluke liver eggs were detected ...

Kinetoplastid protozoans in the family Trypanosomatidae are parasites, many of them responsible for serious diseases in humans and domestic animals. Ornithine decarboxlyase (ODC), a protein at the core of polyamine metabolism, is a potential target for therapies to overcome these diseases. Eukaryotic phylogenies were constructed from full-length genes for ODC to determine the origin of ODC in t...

A phylogenetic tree of most of the major groups of organisms has been constructed from the 352 5S ribosomal RNA sequences now available. The tree suggests that there are several major groups of eubacteria that diverged during the early stages of their evolution. Metabacteria (= archaebacteria) and eukaryotes separated after the emergence of eubacteria. Among eukaryotes, red algae emerged first;...

We studied the coastal zooplankton community structure of six waterbodies of Mathbaria and Bakerganj from January 2008 to June 2009. In total 35 zooplankton species were identified under 26 genera under 20 families under 8 orders from Mathbaria. Among them 6 were protozoans, 24 were rotifers, 3 were copepods, 1 was cladocerans and 1 was ostracods. From Bakergonj a total of 42 zooplankton specie...
