A new method dependent on immune lysis is described for the isolation of intracellular symbiotes from two species of flagellate protozoa Blastocrithidia culicis and Crithidia oncopelti. The symbiote-containing flagellates are exposed to complement and antisera prepared in rabbits against symbiote-free organisms. The immune lysis seems to weaken the plasma membranes of the flagellates so that su...

We have previously observed the apparent displacement of microfilaments over microtubules in the backbone structure of permeabilized flagellates of Physarum polycephalum upon addition of ATP (Uyeda, T. Q. E , and M. Furuya. 1987. Protoplasma.

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...

The intestinal flagellates of termites produce cellulases that contribute to cellulose digestion of their host termites. However, 75% of all termite species do not harbour the cellulolytic flagellates; the endogenous cellulase secreted from the midgut tissue has been considered a sole source of cellulases in these termites. Using the xylophagous flagellate-free termites Nasutitermes takasagoens...

An HIV positive patient presenting a clinical picture of visceral leishmaniasis co-infection was submitted to a bone marrow aspiration after admission to hospital. Amastigotes forms were seen in the bone marrow aspirate and the parasite grew in culture as promastigotes. Molecular analyses showed that the flagellates isolated did not belong to the genera Leishmania, Trypanosoma or Sauroleishmani...

This paper describes the structure of the flagella, basal bodies, and some of the associated fibre systems in three genera of complex flagellates, Trichonympha, Pseudotrichonympha, and Holomastigotoides. Three groups of longitudinal fibres occur in a flagellum: two central and nine outer fibres such as have been repeatedly described in other material, and an additional set of nine smaller secon...

In sunlit waters, significant predation is performed by unicellular, phagotrophic mixotrophs, that is, predators also possess plastids. The success of a mixotrophic lifestyle will depend in part on how well mixotrophs acquire prey relative to specialized heterotrophs. Likewise, consequences mixotrophy for productivity and element cycling the rate efficiency at which consume biomass However, tra...

In order to contribute to an understanding of the geographic distribution of free-living freshwater flagellates, we have investigated the diversity of heterotrophic flagellates occurring in a number of freshwater sites in Tasmania (Australia). This community of organisms has not previously been studied in Tasmania, and the isolation of the freshwater habitats from like habitats elsewhere in the...
