CATDOLL : CATDOLL: How many times magnification of microscope is needed to observe fish parasites?

1. How many times magnification of microscope is needed to observe fish parasites?

At 4 times the magnification, you can see cat fleas, which is the lowest. You can see how big your parasites are. Ichthyophthirius spp. is relatively small, and some can only be seen with an oil lens after staining.

2. What is pig protozoa?

Swine protozoan disease is a common parasitic disease caused by Ascaris suum parasitizing in the small intestine of pigs. The disease mainly harms pigs aged 3 to 6 months, causing poor growth and development and even death.

3. What is Gallus gallus domesticus?

Parasitic diseases are a general term for diseases caused by parasites that temporarily or permanently parasitize on the surface or body of livestock and poultry. The animal attacked by the parasite is called the host, and the entire process of parasite development is called the life cycle. The infection and spread of parasitic diseases must meet three conditions, namely the source of infection, the route of infection and susceptible animals.

Depending on where the parasites live on the host, they can be divided into endoparasites and ectoparasites.

Internal parasites often parasitize the host's internal organs, most commonly the digestive tract. In addition, they can also parasitize the respiratory system, circulatory system, and muscles. Ascaris, tapeworms, and histomonas all belong to this category.

External parasites refer to arthropods that live on the skin and feathers or on the inside of the limbs, such as feather lice that live under chicken feathers and scabies mites that live on the skin of chicken legs.

4. What is cat protozoa?

Cats are infected with parasites. It is very necessary to deworm your pet regularly.

5. How big is the malarial parasite?

30 to 150 microns in length and 25 to 120 microns in width.

Plasmodium belongs to the order Coccidia, family Plasmodium, genus Plasmodium, and is the pathogen of malaria.

Classification of Plasmodium:

There are five main types of human malarial parasites, namely Plasmodium vivax (Pv), Plasmodium falciparum (Pf), Plasmodium malariae (Pm), Plasmodium ovale (Po) and Plasmodium knowlesi. This popular article mainly introduces Plasmodium vivax (Pv).

The morphology and life cycle of Plasmodium:

The basic structure of malarial parasites includes nucleus, cytoplasm and cell membrane.

The life cycle of Plasmodium mainly includes ring body, trophozoite, immature schizont, mature schizont and male and female gametocytes.

6. What is the composition of protozoa?

Insect diseases

Protozoa are the most primitive, simplest and lowest unicellular animals, which are composed of one cell. Protozoa are unicellular eukaryotic animals, which are widely distributed in nature and have many species. Most of them live freely or saprophytically, and only a few live parasitically.

Introduction to Protozoa

Morphology: Individuals are tiny, with many shapes such as willow leaf, round, oval, pear seed, etc., and a few have no fixed shape;

Basic structure: cell membrane, cytoplasm, nucleus

Protozoan life cycle:

●Direct transmission

●Circular transmission type

●Insect-borne

7. Where are amoebas more common?

Cecum and proximal colon, followed by sigmoid colon and rectum

8. What is Chlamydia?

Chlamydia is a type of prokaryotic organism between Rickettsia and viruses, which can pass through bacterial filters and parasitize in living cells. It is a protozoan, a single-cell eukaryotic organism. The entire body of the chlamydia is composed of one cell and has all the functions of life activities.

9. What is the antimalarial parasite?

Plasmodium is a sporozoan transmitted by Anopheles mosquitoes and is the pathogen of malaria. There are four types of Plasmodium parasites that parasitize humans, namely Plasmodium vivax Grassi & Feletti, 1890, Plasmodium malariae Laveran, 1881, Plasmodium falciparum Welch, 1897, and Plasmodium ovale Stephens, 1922. They belong to the Chromatiaceae kingdom, Apicomplexa, Acyrthozoa, Haemosporidae, Plasmozoidae.

These malarial parasites have two hosts, mosquitoes and humans, including sexual reproduction in mosquitoes and asexual proliferation in humans. The Anopheles mosquitoes carrying malarial parasites spread the disease by biting humans, causing malaria with alternating chills and fever, commonly known as "shaking the body". Other types of malarial parasites can infect other animals, including other primates, rodents, and saurians.

10. What is the abbreviation for the classification of Plasmodium?

Malaria can be divided into Plasmodium vivax, Plasmodium falciparum, Plasmodium malariae and Plasmodium ovale according to the pathogen.
