Malaria
Name the infection caused by protozoa: A small percentage of these patients will develop chronic this in which Plasmodium is not fully cleared from the body by the immune system and persists in the liver, causing disease relapse for several years. Risk of death is highest for fetuses, newborns, children, pregnant women, and other young adults.

Malaria
Name the infection caused by protozoa: Has been known since ancient times (derives from Latin: "mal" meaning "bad" and "aria" meaning "air") and is still a significant global health problem. Until the early to mid-20th century, it occurred in temperate and tropical climates worldwide, including parts of Europe and the US. Public health efforts in wealthy countries located in temperate climates that greatly reduced mosquito populations and effectively treated malaria patients, eliminated this in those areas, but the disease continues to be a significant threat in tropical areas of the world where mosquitoes are harder to control. Protozoan agent: Plasmodium (there are five species of Plasmodium, but there is no need to learn the names of the individual species. Is a vector-borne disease: Plasmodium is transmitted from human-to-human by mosquitoes. In particular, female Anopheles mosquitoes are the vectors (no other mosquito species can transmit Plasmodium). In addition to serving as vectors, female Anopheles mosquitoes are one of the required hosts in the life cycle of Plasmodium. The other required hosts for Plasmodium are humans. In humans, Plasmodium first infects cells in the liver, then goes on to infect red blood cells. Symptoms: Malaise, Fatigue, Aches, Nausea, Chills, Fever, Sweating. Symptoms are directly linked to the rupture of red blood cells caused by Plasmodium. Depending of which species of Plasmodium is involved, the red blood cells will rupture synchronously in either 48 or 72 hour cycles, therefore, the symptoms of malaria rise and fall in either 48 or 72 hour cycles. Some patients will develop anemia which is a lower than normal number of red blood cells. Some patients will develop kidney, liver, and/or spleen damage due to an accumulation of cellular debris from ruptured red blood cells. These organs are responsible for filtering the blood, so the cellular debris accumulates in them, resulting in organ enlargement and damage. The most serious complication is cerebral (brain) malaria. Cerebral this occurs if the infected red blood cells adhere to blood vessels in the brain, reducing blood flow. Cerebral this a is the worst case scenario for these patients and can result in coma and/or death.

Sleeping under an insecticide-treated bed net (Anopheles mosquitoes are night feeders). This is a very cost effective approach that has been widely promoted by global health agencies. Elimination of standing water to reduce mosquito breeding sites. Use of certain insecticides within homes and nearby. Use of window and door screens. Use of mosquito repellants. Staying inside at night (assuming the house has screens). A promising vaccine candidate is in the testing phases, but is not yet licensed. The search for an effective vaccine has been impeded by the antigenic variation of Plasmodium (the organism can change its antigens into thousands of different molecular types).

Dermatophytes digest keratin which is found on the surface of the skin, hair and nails, using it as their source of nutrition. Is classified as cutaneous because Dermatophytes do not invade beyond the surface of the skin, hair strands, or nails. There are two common routes of transmission: Via direct contact with infected skin surfaces, hair, or skin cells that have been shed from an infected person. Via contact with fomites such as bedding, clothing, wrestling mates, shower tiles, etc, that are contaminated with infected hair or skin cells that have been shed from an infected person. There are two other possible routes of transmission: Via contact with animals that have certain Dermatophyte infections. Via contact with soil that contains Dermatophytes. Symptoms vary depending on the location of the infections and can include: Itchy skin, Red rings or patches in the skin, Hair loss, Thick, discolored nails. These diseases are named by the part of the body that is affected. Tinea capitis: Ringworm of the scalp. Tinea corporis: Ringworm of the body. Tinea pedis: Athlete's foot Tinea unguium: Ringworm of the nail. What are the potential complications?: None. Treatment: Anti-fungal drugs can cure this., Topical application (creams or gels) of anti-fungal drugs is usually sufficient. Certain types of this may require oral anti-fungal drugs Prevention of this: The only prevention is to avoid contact with Dermatophytes, but that is difficult to do because hair and skin cells are continuously shed and it isn't possible to know whether contact is being made with hair or skin cells that have been shed by an infected person.

In fact, some experts believe that T. gondii influences the functions of the human brain as well The vast majority of infected people experience no symptoms or mild "flu-like" symptoms. Infected people who are immunocompromised can develop subacute encephalitis. Subacute encephalitis is a very serious disease in which extensive lesions develop in the brain. Infected patients who are immunocompromised patients can also develop damage to the heart and/or lungs that can be fatal. The most significant problem regarding toxoplasmosis is that if T. gondii infects a pregnant woman, T. gondii can cross the placenta and infect the developing fetus: Fetal infections that occur during the 1st or 2nd trimester of pregnancy can result in stillbirth, or in the birth of a newborn infant with an enlarged spleen and liver, liver failure, brain damage, and/or blindness. Treatment: Several anti-protozoan drugs. Prevention: Pregnant women are advised to avoid all possible contact with cat feces.

Is is an STI: T. vaginalis is transmitted via direct (sexual) contact between bodily fluids that contain the organism and the mucous membranes of an uninfected person. Like other STI agents, T. vaginalis cells cannot survive for extended periods of time outside of a human host.. T. vaginalis cannot transform into cysts that would help it survive outside a host. Females develop a vaginal discharge (white to green in color), vaginal irritation, or have no symptoms. Males usually have no symptoms. The most significant problem is that pregnant women with this are at increased risk of going into labor prematurely and giving birth to a low birth weight (premature) infant.. Low birth weight (premature) infants often require extensive, expensive hospital care in a neonatal intensive care unit, and depending on how premature they are, can have developmental and other long-term problems.. Like other STIs, the inflammation that results from host defenses against T. vaginalis can increase the risk of HIV infection. Like other STIs, this can result in female infertility. Treatment: Anti-protozoan drugs. Some strains of T. vaginalis are resistant to certain drugs which complicates the treatment plan.
