Cymothoa Exigua in Human and Life Cycle

Jul 04, 2012 > Various
Cymothoa exigua is a tiny crustacean that sneaks up on a fish (specifically, a red snapper) and works its way in through the gills. Typical parasite behavior so far. Then it attaches itself to the base of the fish's tongue, the tongue evidently being the tastiest part of the fish (get it!?). The parasite uses its claws to dig into the tongue and drink the fish's blood--and that's just the beginning

Cymothoa Exigua in Human

It is currently believed that Cymothoa Exigua are not harmful to humans unless picked up alive, in which case they can bite.

Cymothoa Exigua in Human and Life Cycle

A tongue-eating parasite inside the mouth of a red snapper purchased from a London fishmonger recently revolted its buyer and fascinated scientists.

Previously, scientists believed fish infected with the parasite, nicknamed the "tongue louse," existed solely in the Gulf of California. The find in England suggests the parasite's range may be expanding, according to a recent press release issued by a museum in England.

But does the Cymothoa mouth-squatter leave its fishy friend tongueless? Of course not. It does what any crafty parasite would do and replaces the old tongue with its own body.

The fish is actually able to use the parasite just like a normal tongue, only it has to share all the food with its new friend. Yes, the whole foster-tongue thing seems like a pretty nice gesture on the part of ol' Cymothoa until you remember there was nothing wrong with the fish's old tongue in the first place.

Cymothoa Exigua Life cycle

Not much is known about the life cycle of Cymothoa Exigua. It exhibits sexual reproduction. It is likely that juveniles first attach to the gills of a fish and become males. As they mature, they become females, with mating likely occurring on the gills. If there is no female present, within a pair of two males, one male can turn into a female after it grows to 10mm in length. The female then makes its way to the fish's mouth where it uses its front claws to attach to the fish’s tongue.

Venereal warts (also known as genital warts or condylomas) are caused by a small group of viruses known as human papilloma viruses (HPV). A person becomes infected when an HPV penetrates the skin and mucous membranes of the genitals or anus through sexual contact.
Cymothoa Exigua in Human and Life Cycle #1Spinal Stenosis Definition and Treatment
What is defintion of Spinal Stenosis. Spinal stenosis is a narrowing of one or more areas in your spine — most often in your neck or lower back. This narrowing can put pressure on the spinal cord or spinal nerves at the level of compression. Stenoses of the vascular type are often associated with unusual blood sounds resulting from turbulent flow over the narrowed blood vessel. This sound can be made audible by a stethoscope, but diagnosis is generally made or confirmed with some form of medical imaging. aortic stenosis (AS) a narrowing of the aortic orifice of the heart or of the aorta near the valve. hypertrophic pyloric stenosis narrowing of the pyloric canal due to muscular hypertrophy and mucosal edema, usually in infants.

Are you looking for glaucoma treatment guidelines? Glaucoma is an eye disorder in which the optic nerve suffers damage, permanently damaging vision in the affected eye(s) and progressing to complete blindness if untreated. It is often, but not always, associated with increased pressure of the fluid in the eye (aqueous humour). The term 'ocular hypertension' is used for cases having constantly raised intraocular pressure (IOP) without any associated optic nerve damage. Conversely, the term 'normal' or 'low tension glaucoma' is suggested for the typical visual field defects when associated with a normal or low IOP.

Are you looking for sinus infection treatment? Sinus infections are caused by infections from a pathogenic microorganism (virus, bacterium, or fungus), which grows within a sinus and causes intermittent blockage of the sinus ostium. Most people do not transmit sinus infections; most clinicians agree that except for rare instances, sinus infections are not contagious but arise from mainly viruses and bacteria that, by chance, contaminate a person who sinuses support their proliferation because of minor, and rarely, major abnormalities in the person's sinus tissue (for example, swelling, inflammation, abnormal mucus production, and rarely, facial or nasal trauma).

Syphilis, the other well-known sexually transmitted disease, is also caused by a bacterial organism, the spirochete known as Treponema pallidum. Because it s extremely delicate and dies readily upon exposure to air, dryness, or cold, the organism is generally transferred only through direct sexual contact. Typically, this means contact between sexual organs during intercourse, but in rare instances, the organism enters the body through a break in the skin, through deep kissing in which body fluids are exchanged, or through some other transmission of body fluids.

The importance of an early diagnosis of allergy cannot be overemphasized. This diagnosis should be made in infancy or early childhood. This involves not only recognition that the condition affecting the child is allergic, but also a serious attempt at discovering the cause of the allergy. In doing this, however, one meets frequently with great deal of resistance by the mother because she does not want to see the child hurt, r because she somehow has a vague suspicion that skin testing endangers the child's health. The mother must understand the importance of such an early diagnosis. She must realize that delay is equivalent to neglect, and that neglect needlessly expose the child to the dangers of complications which may result from an untreated allergy a case of hay fever or case of asthma in a child. After a few years, however, this condition becomes complicated by nasal infection or by bronchitis, or by changes in the tissues of the lungs. These changes become refractory to treatment, so that even if the allergy is discovered, treatment of complications becomes difficult if not impossible. The mother must also understand that skin testing, if properly done, is not dangerous and does not affect the child's physical condition.
Cymothoa Exigua in Human and Life Cycle #6Antioxidant vitamins
Three vitamins are classified as antioxidants – vitamins C, E, and beta-carotene. Antioxidants are protective substances because they help neutralize the activity of free radicals. Free radicals are naturally produced chemicals that arise from normal cell activity. When ever the body uses oxygen or is exposed o a toxin, such as cigarette smoke, it forms free radicals. These unstable chemicals can damage cells throughout the body. They may damage a cell's DNA in ways that lead to cancer, may interact with cholesterol in the bloodstream and form oxidized Low-density lipoprotein (LDL) may cause cataracts and rheumatoid arthritis, and may be factor in the physiological changes associated with the aging process. Anything that interferes with the destructive effects of free radicals offers a health advantage. Vitamins C, E, and beta-carotene are believed to prevent the oxidation of cholesterol and other molecules linked to the diseases mentioned previously, most notably heart disease and cancer. A common cooking practice illustrates this antioxidant effect: some foods like bananas, peaches, apples, and potatoes quickly turn brown when exposed to air. However, when such foods are dipped in lemon or orange juice, the vitamin C in the juice acts as an antioxidant and prevents browning.

What is the treatment for low back pain? So, how is low back pain treated? Well, as described above, the treatment very much depends on the precise cause of the low back pain. Moreover, each patient must be individually evaluated and managed in the context of the underlying background health status and activity level.

A whole foods diet is a basic, simple way of eating that is just as it sounds. Meals in the diet are composed of whole foods that are unprocessed or as minimally processed as possible. Another way of defining a whole food is put forth by Beatrice Trum Hunter, author of "A Whole Foods Primer." Hunter says that whole foods have "nothing added and nothing taken away." That is, they are as close to their natural state as possible. The School of Medicine at Texas Tech University suggests that whole foods diets are especially suitable for people with obesity or hypertension.
Cymothoa Exigua in Human and Life Cycle #9Stomach Pain After Eating in Children
Chronic and recurrent abdominal pain is common in children and the term refers to pain for which a specific cause (by history, physical examination, or laboratory tests) has not been determined. It occurs in 9 to 15 percent of all children. In boys, pain is most common between ages 5 and 6 years. Girls have pain most commonly between 5 and 6 years and 9 and 10 years. Children often complain of stomach ache (pain in the tummy). It can be a sign of illness, but often a child will have pain, but not be unwell. Some of the children who have abdominal pain will be having a difficult time, perhaps at home, perhaps at school, but many children with strong pain do not seem to be stressed or unwell. Research has shown that up to 10% of children have abdominal pain which comes and goes. An illness causes the pain in only about 5% of these children.

More than 10 million people are victims of leprosy, an infectious disorder also known as Hansen’s disease. Although leprosy is more common in tropical regions, where up to 10 percent of some population groups may be affected, the disease also occurs in several northern countries, including the United States, where the disease is found in coastal states from California through Texas and Louisiana, and from Florida to New York. Ancient medical writings indicate that leprosy was known in China and India about 3,000 years ago but did not spread to the eastern Mediterranean until A.D. 500 or 600.
Cymothoa Exigua in Human and Life Cycle #11Leprosy Symptoms and Causes
Leprosy or Hansen's disease (HD) is a chronic disease caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis. Named after physician Gerhard Armauer Hansen, leprosy is primarily a granulomatous disease of the peripheral nerves and mucosa of the upper respiratory tract; skin lesions are the primary external sign. Left untreated, leprosy can be progressive, causing permanent damage to the skin, nerves, limbs and eyes. Contrary to folklore, leprosy does not cause body parts to fall off, although they can become numb or diseased as a result of secondary infections; these occur as a result of the body's defenses being compromised by the primary disease. Secondary infections, in turn, can result in tissue loss causing fingers and toes to become shortened and deformed, as cartilage is absorbed into the body.
Cymothoa Exigua in Human and Life Cycle #12Symptoms of Heart Disease in Women
Cardiovascular disease is the leading cause of death among American women, is more lethal in women than men, and is less aggressively treated in women than in men. Perhaps most troubling is how little women understand about cardiac risk, their ability to control it, and consequently to improve their lifestyle and reduce heart disease. Education and behavior modification are solutions to improving mortality and morbidity from heart disease in the USA. As we move into the next century it will be key to teach women about their risks for the number one killer.
