trophozoite

Transmission takes place directly because the trophozoite does not have a cyst.

This trophozoite is the cell that begins the process of schizogony.

For example, a healthy fish with a newly attached trophozoite will not yet have clinical disease.

A trophozoite attached to the gills usually is not readily seen.

While it is feeding and growing, the cell is known as a trophozoite.

A subclinically infected fish may initially only have a single trophozoite.

After a few days, the parasite turns into a trophozoite, a jelly like substance.

On average, a Balamuthia trophozoite is approximately 30-120 m in diameter.

The pseudopodia form at different points along the cell, thus allowing the trophozoite to change directions.

Within the red blood cell, the protozoa become cyclical and develop into a trophozoite ring.

The trophozoite stage is separated from erythrocyte by single membrane (in the other groups there usually 2 or more).

The trophozoite will not become visible to the naked eye until it has fed on the fish and grown to one or two millimetres.

These genes are expressed at early trophozoite stages.

They are divided into three taxa based on habitat, host range and trophozoite morphology.

Infection of the erythrocyte decreases the mean to -14.6 mV at the trophozoite stage.

The trophozoite is pleomorphic and uninucleated, but binucleate forms are occasionally seen.

The trophozoite parasitises erythrocytes or other tissues in the vertebrate host.

Once ingested by a host, the trophozoite emerges to an active state of feeding and motility.

The trophozoite is usually irregular in outline.

Within both the trophozoite and schizont categories, large numbers of genes belong to functionally related processes.

In the typical gregarine life cycle a trophozoite develops within a host cell into a plasmodium.

The trophozoite grows within the host cytoplasm.

During early sexual development the gametocyte has a similar morphology to a trophozoite but subsequently undergoes a dramatic shape change.

This forms a set of reticular structures adjacent to the nuclear regions during the trophozoite and schizont stages.

The trophozoite has a single nucleus, prominent for nuclear endosome and many cytoplasmic vacuoles.
