Effect of bioamines on the cellular differentiation of Hartmannella culbertsoni
Biochemical Pharmacology, 1974Abstract Epinephrine, 5-hydroxytryptamine, dopamine and tyramine induce axenic encystation of the free living amoeba Hartmannella culbertsoni . Cycloheximide inhibits encystation of amoeba mediated by the amines. The amines uniformly stimulate 3 to 4-fold the ability of the cells to synthesize cyclic 3′,5′-adenosine monophosphate from adenosine ...

Two New Species of Hartmannella Amebae Infecting Freshwater Mollusks
The Journal of Protozoology, 1968SYNOPSIS. Two new species of small amebae, Hartmannella biparia n. sp. and Hartmannella quadriparia n. sp., were 1st observed in the freshwater mollusks Bulinus globosus and Biomphalaria pallida, respectively. The amebae multiplied in cytoplasmic vacuoles in host cells, particularly in foci in the mantle collar, foot, and intestinal wall.

Extrinsic Requirements for Encystation by the Soil Amoeba, Hartmannella rhysodes*
The Journal of Protozoology, 1963SYNOPSIS. The environmental factors causing encystation in Hartmannella rhysodes, a small soil amoeba, appear to be an elevated osmotic pressure, Ca2+ and Mg2+, aeration and a decrease in carbon sources. After 36 hr under these conditions, amoebae harvested during active growth encyst. Nutrients essential for growth, other than carbon sources, have no

The Physiology of Encystment of Hartmannella castellanii*
The Journal of Protozoology, 1969SYNOPSIS. Some aspects of the physiology of encystment of the soil amoeba Hartmannella castellanii in a replacement encystment medium consisting of 5 × 10‐2 M MgCl2 have been investigated. It is suggested that measurement of the cellulose produced during encystment in the synthesis of the cyst wall is a more reliable measure of the process than other ...

Intracellular survival of Francisella tularensis in Hartmannella vermiformis
2010Francisella tularensis is a highly infectious, facultative intracellular bacterium and the causative agent of tularemia. The natural reservoir of the bacterium is largely unknown. Although it has been shown that protozoa may harbor it the reservoir in nature has not been definitely identified. In this study, the ability of F. tularensis subsp. novicida

The Amino Acid Requirements of the Soil Amoeba, Hartmannella rhysodes Singh*
The Journal of Protozoology, 1962SYNOPSIS. A chemically defined culture medium has been developed for the soil amoeba Hartmannella rhysodes Singh which contains the minimum essential organic requirements for growth. The medium consists of 7 amino acids, 3 vitamins, a carbon source (e.g. glucose) and inorganic salts.
