Dormant stage
- A cyst refers to a dormant stage of a protozoan that enables them to survive in unfavorable environmental conditions. Therefore, the cyst is the transmission state of protozoa. On that account, the cyst is infectious. The process of formation of the cyst is referred to as encystation.

The stages of parasitic protozoa that actively feed and multiply are frequently called trophozoites; in some protozoa, other terms are used for these stages. Cysts are stages with a protective membrane or thickened wall. Protozoan cysts that must survive outside the host usually have more resistant walls than cysts that form in tissues.

Cyst and trophozoite are two stages of the lifecycle of protozoans. Protozoa are a diverse group unicellular, eukaryotic microorganisms. Amoeba, Plasmodium, Paramecium, and ciliophora are examples of protozoans. The main difference between cyst and trophozoite is that cyst is the dormant stage that helps to survive in unfavorable environmental cond...
A cyst refers to a dormant stage of a protozoan that enables them to survive in unfavorable environmental conditions. Therefore, the cyst is the transmission state of protozoa. On that account, the cyst is infectious. The process of formation of the cyst is referred to as encystation. As encystation takes place in the rectum of the host, cysts can ...
A trophozoite refers to the growing stage of the parasitic protozoans that absorb nutrients from the host. The formation of the trophozoite from a cyst is referred to as excystation. The excystation takes place in the large intestine of the host at the subsequent ingestion of the cyst by the host. Trophozoites are not resistant structures. Generall...
Cyst and trophozoite are two stages of the lifecycle of protozoans.Both cyst and trophozoite are unicellular.Both cyst and trophozoite consist of visible nuclei.Both cyst and trophozoite contain contractile vacuoles.Definition
Cyst: A cyst refers to a dormant stage of a protozoan that helps to survive in unfavorable environmental conditions. Trophozoite: A trophozoite refers to the growing stage of the parasitic protozoans that absorb nutrients from the host.
Formation
Cyst: The cyst is formed in a process called encystation. Trophozoite: The trophozoite is formed in a process called excystation.
Type
Cyst: The cyst is a dormant stage of protozoans. Trophozoite: The trophozoite is an active and reproductive stage of protozoans.
Dec 24, 2022 · Some protozoa have life stages alternating between proliferative stages (e.g., trophozoites ) and dormant cysts. As cysts, protozoa can survive harsh conditions, such as exposure to extreme temperatures or harmful chemicals, or long periods without access to nutrients, water, or oxygen for a period of time.
Apr 19, 2001 · Cysts are typically resting, dormant and/or resistant stages in the full life cycle of many protozoan species, sometimes playing a role in dispersal of the organism. Spores are a stage commonly associated with multiplication and propagation of a protozoan organism, sometimes having a resistant wall and often, in parasitic forms, serving as an ...

Certain protozoan parasites use survival strategies to reside outside the host such as the formation of cysts. This dormant and resistant stage results from the complex process of encystment that involves diverse molecular and cellular modifications.

A trophozoite (G. trope, nourishment + zoon, animal) is the activated, feeding stage in the life cycle of certain protozoa such as malaria -causing Plasmodium falciparum and those of the Giardia group. [1] . The complementary form of the trophozoite state is the thick-walled cyst form.
Many of the protozoa form a resistant, dormant structure called a cyst. Parasitic protozoa are identified by the active feeding stage, called a trophozoite, in addition to the cyst stage, both of which may be found in the feces.
