The main difference between Ova and Cyst is that Ova is the lifespan of a parasite, while Cyst is a lifespan of parasitic protozoa.
Ovules versus cyst
Ove is known as parasitic worm eggs that are present in animal feces which are a sign of parasitic disorders; on the other hand, the cyst is known as the confrontational stage of a parasitic protozoan that helps to survive in unfavorable conditions. The meaning of the ovules is that it is the stage of propagation of the parasitic worms; on the contrary, the meaning of the cyst is that it is the stage of propagation of the parasitic protozoa.
The ovules are typically large in size, 50-130 mm long and 20-70 mm wide; on the other hand, the size of the cyst is normally small 40 to 60 mm wide. The thick wall is present in the ovules, while there is normally a thin wall in the cyst.
The ovules are occupied by the cytoplasm and the nucleus; on the other hand, as the cyst is more fragile than the ovules, it is always filled with fluid. Ovules are the reproductive cell of parasitic worms by binary fission or conjugation; on the other hand, the cyst is not a reproductive cell of the parasitic protozoa.
The shape of the ovules is pointed at its anterior end, with two contractile vacuoles and a funnel-shaped cytostome; on the contrary, the cyst is spherical and its wall is made up of one or two layers. Eggs may or may have poor motility; on the other hand, the cyst is not mobile. The surface of the ovules is covered with cilia; on the other hand, the surface of the cyst is covered with a hard and thick wall and is made up of cilia, which are sometimes visible underneath.

Ovules are considered parasitic worm eggs that are present in feces or waste products as a symbol of the parasitic disorder in the particular individual. Parasitic worms or hookworms often lay eggs while reproducing.
Many worms or parasites like flukes or tapeworms are generally hermaphroditic, while some worms like nematodes are normally monogenic or unisexual. The worm normally gives thousands of eggs a day. The structure of the ovules is that it comprises a strong protective shell that protects them from negative environmental factors or conditions.
The shell of the ovules is made up of three different layers: the outer layer is known as the protein layer , the middle layer is a chitinous layer, and the inner layer is the lipoid layer . The ovules are sustainable for 1-2 months in fresh water, soil and sewage.
Worm eggs enter the host individual through fecal-oral communication. In most parasitic worms, the larvae hatch from sustainable eggs within the host’s body.
What is the cyst?
A cyst is considered a confrontational stage that helps a protozoan survive in unfavorable conditions. A cyst is infectious because it is the stage of propagation of parasitic protozoa. The formation of the cyst is known as the encystation process, which occurs in the rectum of the host individual. That is why the cyst can be found and identified in animal feces.
The structure of the cyst is spherical. The cysts are covered or lined with a hard or strong cyst wall that has two layers. In young cysts, contractile vacuoles, cilia, and macromolecules are visible. The organelle structures of old cysts are granular. Most of the mobility and metabolism is captured within the cyst.
The trophozoite is known as the growth and reproduction stage of the cyst. Excision is considered as the formation of a trophozoite from a young cyst. The arousal process occurs in the host’s large intestine at the next ingestion of the cyst by the host.
Trophozoites do not consist of strong forms or structures. Trophozoites are generally covered with cilia on the surface, so they are mobile. Trophozoites consume foodstuffs or nutrients from the perch or host and reproduce within the host.
The cyst is also present in nematodes and bacteria. The cysts are generally not affected other than the spores of the bacteria. Cysts in bacteria allow the dispersal of bacteria. The bacteria then germinate in the presence of favorable conditions. In plant parasitic nematodes, the cyst occurs as part of their life cycle.
- The eggs of bacteria or protozoa found in feces, and is the symbol of the parasitic disorder. It is known as ovules; On the other hand, the resistance stage of a parasite, which generally helps it survive in unfavorable environmental conditions, is known as a cyst.
- The shape of the ovules is oval and pointed at the front end; on the contrary, the shape of the cyst is spherical.
- The egg cell structure has a funnel-shaped cytostome near the anterior end and has two contractile vacuoles; on the other hand, the cyst wall is made up of one or two layers.
- The eggs are dull motile or sometimes rotary, whereas the cyst is not motile in the early stages.
- The ovules are important for the propagation stage of the parasitic worms; on the other hand, the cyst is important for the spread of parasitic protozoa.
- The size of the ovules is between 50-130 mm long and 20-70 mm wide, and they are generally larger; on the contrary, the size of the cyst is 40-60 mm and they are generally smaller than the ovules.
- Eggs normally contain a thick wall; on the other hand, the cyst generally consists of a thin wall.
- The cytoplasm and nucleus fill the ovules; on the other hand, the cyst is filled with fluid and therefore they are more fragile and brittle.
The above discussion concludes that the ovules and the cyst are the two stages of propagation of the protozoa. The ovules are known as the propagation stage of parasitic worms, while the cyst is known as the propagation stage of parasitic protozoa.
