Problem description:

For cats, after the eggs are drilled out of the *** and ovulated, the eggs can survive. How long

Analysis:

Tapeworm eggs survive for a long time in the outside world. They can survive for one year at about 4℃, 3 to 4 months at -30℃, and only survive at 37℃. It can live for about 7 days, and the eggs have strong resistance.

Tapeworms are a common parasitic disease in cats. There are many types of tapeworms that cause taeniasis in cats, among which the main ones are Sparganomata, Taenia, Mesotaenia, and Diploid tapeworm. Taeniasis can sometimes infect people and is very harmful.

[Characteristics of the tapeworm and the spread of the disease] Tapeworms are dorsally and ventrally flat, with a white or milky white opaque tape-like body. The tapeworm body is composed of three parts: the head segment, the neck segment and the body segment. The number of joints varies depending on the type of insect, some have a few joints, and some have hundreds of joints. Therefore its length ranges from a few centimeters to several meters. The scolex is small and spherical or fusiform. The cervical segment is the thinner and shorter part after the scolex. It is not divided into segments. The body segments are quadrilateral. The somites close to the neck segment are small, and the reproductive organs inside them have not yet developed, and are called immature somites. This is followed by the mature body segments. Tapeworms are hermaphrodites, so there are male and female reproductive organs in the mature body segments. The uterus of the last segment is filled with eggs, while other parts of the reproductive organs have shrunk or degenerated. This segment is called a gestational segment. It can fall off or break down by itself and be excreted with feces. Therefore, if you see "lasagna"-like quadrilateral body segments in a cat's feces, it means that the cat is infected with tapeworms. After the eggs are released, they are eaten by various intermediate hosts and develop into larvae. After these larvae are ingested by cats, they develop into adult worms and cause various clinical symptoms in cats.
