Whirling disease hurts young fish the most, and can hurt bones and nerves. Fish with the disease do not swim very well, and they "whirl" or spin instead of swimming straight. This makes it hard for the fish to get food and get away from danger. Dealing with "M. cerebralis" costs more money than most other parasites in its group (which are called "myxozoans"). People do not get sick with whirling disease, though; only fish do.
"M. cerebralis" has become well-established, particularly in North America. It has caused the decline of whole cohorts of fish.
"M. cerebralis" has many stages ranging from single cells to bigger spores. Scientists have not studied all the stages very well yet.
"M. cerebralis" has many diverse stages ranging from single cells to relatively large spores, not all of which have been studied in detail.
The kind of "M. cerebralis" that can attack fish is called a "Triactinomyxon", and there is a picture of it on the right. There are three "tails" that are each about 200 micrometers long, and another piece that is about 150 micrometers (μm) long. That piece has 64 cells in it. There are also three harpoon-like weapons that can attack the fish. They shoot into the fish, making a hole that the 64 cells can go into. Those cells make more cells that go to the cartilage near the fish's brain.
The kind of "M. cerebralis" that comes out of fish is called a "Myxospore". They are sort of round and fat in the middle like a lentil or a convex lens. They are about 10 micrometers across and are made of six cells. Two are for the harpoon weapons, two are for protecting the Myxospore, and two are for going into a worm after the weapons make a hole. Myxospores from "M. cerebralis" look a lot like Myxospores from other species that are sometimes in fish skin, muscle, or brains, and so it's hard to tell them apart.

Bahá'í Faith
The Bahá'í Faith is an Abrahamic religion started in the 1800s by an Iranian person called Bahá'u'lláh who was born in Tehran, Iran. Followers of this religion call themselves Bahá'ís. The name Bahá'u'lláh is Arabic for "The Glory of God". "Glory" is a word that means "importance", "power", and "beauty". Bahá'ís believe Bahá'u'lláh is a representation of God, or speaks for God, and he shows people God's importance, beauty, and brightness.
Bahá'ís are monotheists, which means that they believe in one God. They believe Bahá'u'lláh carried a message from God. Bahá'u'lláh said he was not the only person to carry a message from God, and he was not the last to carry a message from God. He taught that the people who started the other major religions also represented and carried messages from God, such as Jesus, Moses, Krishna, Abraham, Muhammad, the Buddha and others. He called these people "Manifestations of God." They believe the messages from the Manifestations of God get more and more difficult to understand. They say the ones that came earlier on had a more simple message than the ones that came later. Because God is greater than the whole universe, Bahá'u'lláh said that human beings cannot completely know God. He said that God wants people to know as much about him as they can. Bahá'u'lláh wrote God sends special people to manifest (show) himself to ordinary humans. Without the Manifestations of God we could not know God. Bahá'ís believe the God they pray to is the same God Abraham spoke to, Jesus talked about, and Krishna said in Gita. Since Bahá'u'lláh was born in a Muslim family, Bahá'ís are sometimes mistaken as Muslims. Bahá'u'lláh is considered the prophet/manifestation of the present day. Bahá'ís say that he is not the last prophet/manifestation of God. They think there will not be another prophet for 1,000 years after Baha'u'llah's death.
The Bahá'í Faith began on 1844 when a man called the Báb said he had a message from God. He said that it was his job to make sure that people were ready for the most important message from God who would be sent soon. This started a religion, followers of this religion were called Bábís. Many people became Bábís in the country of Iran, which was called Persia at the time, and this made the government of Persia and the Muslim priests angry. They arrested and killed the Bab and his followers. Even though this happened, people still followed this religion.
Before Bahá'u'lláh said he had a message from God, he was a member of the religion that was started by the Báb. He became very famous among the Bábís. When the Báb was killed, some Bábís got very angry and tried to kill the king of Persia, even though Bahá'u'lláh told them not to kill him. When the Babis were caught, the government put many Bábís in jail, including Bahá'u'lláh. While in jail at Tehran, Bahá'u'lláh said he saw an angel that he called the "maid of heaven". The angel told him that he had to teach a message from God to the people of the world. The angel said that God would rescue and protect him so that he could teach this message. Eventually, he was released from jail and the government of Persia made him move to Baghdad, which was then controlled by the king of the Ottoman Empire.
While Baha'u'llah was in Baghdad, he had many problems, but he also made many friends. The government of Persia was unhappy that he seemed to be doing well in Baghdad, and so they asked the Ottoman Empire to move him further away from Persia. When he was about to leave, in 1863, he held a festival for 12 days on a small island in the Tigris river, which he called Ridvan, which means paradise. There he told some of his closest friends and family that he was the promised one of all of the major religions, and that eventually the whole world would know his message.
Eventually the Ottoman Empire sent him to many different cities, including Constantinople, Adrianople, Alexandria, and eventually Akka. He was in different jails this whole time, and the city of Akka had a big wall around it, and it was one big jail. While he was in Baghdad, and after, he wrote many books and letters to answer questions that his friends and followers asked him. At one point he was poisoned, so that he could not write anymore because his hands shook so badly. After that, he had someone write down what he said. When he was even older, his oldest son, `Abdu'l-Bahá arranged to have him move into a house near Mount Carmel, and he stayed there until he finally died in 1892.
After he died, people followed `Abdu'l-Bahá. Bahá'u'lláh had written that `Abdu'l-Bahá had special powers, and that God would make sure that if `Abdu'l-Bahá explained anything that Bahá'u'lláh said, then the Bahá'ís should believe that explanation. `Abdu'l-Bahá also wrote a lot of letters and gave talks, and eventually visited Paris, London, Montreal, New York City, San Francisco and other cities in the west. This helped the Bahá'í Faith to spread in Europe and North America. He died in 1921. He left a will, where he told the Bahá'ís to follow his grandson, Shoghi Effendi.
Shoghi Effendi was born in 1900 and was only a young man when his grandfather died and he became the leader of the Bahá'ís. He helped make the different agencies and councils that run the Bahá'í Faith today, and organized the religion in many ways. He also wrote many books and letters to explain the teachings of his grandfather and great-grandfather. He lived until 1957 and died in England.
