Okayyy I need major biology help!?

Question

Here are the protozoan

Cryptocarion irritans (Ich in fish)

Toxoplasma gondii

Trypanosoma cruzi

Coccidiosis

Babesia

I need to know

the disease the protist causes,

the host or hosts it infects,

symptoms the organism causes,

any danger to humans,

and so forth.

and a pic if possible..

If you know any of the questions about any of the protozoans please let me know Thanks very much!

Answer 1

1- Cryptocaryon irritans parasitizes marine fish, and is one of the most common causes of disease in marine aquaria. The symptoms and life-cycle are generally similar to those of Ichthyophthirius in freshwater fish, including white spots, on account of which Cryptocaryon is usually called marine ich. However, Cryptocaryon can spend a much longer time encysted.

Infections can be extremely difficult to treat because of other creatures, such as corals and other invertebrates, which will not survive standard treatments. Ideally fish with Cryptocaryon are quarantined in a hospital tank, where they can be treated with a copper salt or using hyposalinity. The display tank needs to be kept clear of fish for 6-9 weeks, the longer the better. This gives time for the encysted tomonts to release infectious theronts, which die within 24-48 hours when they cannot find a host.

2- The definitive host of T. gondii is the cat, but the parasite can be carried by the vast majority of warm-blooded animals, including humans. Toxoplasmosis, the disease of which T. gondii is the causative agent, is usually minor and self-limiting but can have serious or even fatal effects on a fetus whose mother first contracts the disease during pregnancy or on an immunocompromised human or cat.

Preventing Toxoplasma during pregnancy involves avoiding cat f***s. If possible keep cats strictly indoors to avoid contact with parasites. If gardening wear protective rubber gloves and wash hands throughly after. Avoid eating raw meat and unwashed fruit and vegetables.

3-The species causes the trypanosomiasis diseases in humans and animals in America. Transmission occurs when the reduviid bug deposits f***s on the skin surface and subsequently bites; the human host then scratches the bite area and facilitiates penetration of the infected f***s.

Human American Trypanosomiasis, or Chagas disease, is a potentially fatal disease of humans. It has two forms, a trypomastigote found in human blood and an amastigote found in tissues. The acute form usually goes unnoticed and may present as a localized swelling at the site of entry of the parasites in the skin. The chronic form may develop 10 to 20 years after infection. This form affects internal organs (e.g. the heart, esophagus, colon and the peripheral nervous system). Affected people may die from heart failure.

Acute cases are treated with nifurtimox and benznidazole, but there is currently no effective therapy for chronic cases.

4-Coccidiosis is the disease caused by coccidian infection. Coccidiosis is a parasitic disease of the intestinal tract of animals, caused by coccidian protozoa. The disease spreads from one animal to another by contact with infected f***s, or ingestion of infected tissue. Diarrhea, which may become bloody in severe cases, is the primary symptom. Most animals infected with coccidia are asymptomatic; however, young or immuno-compromised animals may suffer severe symptoms, including death.

While coccidian organisms can infect a wide variety of animals, including humans, birds, and livestock, they are usually species-specific. One well-known exception is toxoplasmosis, caused by Toxoplasma gondii.

5- Babesia is a piroplasmid parasite of blood cells and is found in the phylum Apicomplexa. This group is characterized by its round, rod or abstract shape and lack of any mobility structures such as cilia or flagella. The species B. bigemina was noted as the first vector-based disease described in history.

There are many different Babesia species, several of which can infect humans. These different types may be found in red blood cells, lymphocytes, and histiocytes as well as other blood cells. They are normally characterized by their shape within these cells. Babesia is a parasite, which means that it lives at the expense of its host.

Goooood Luck :)
