Vector organisms are parasites that transmit various diseases. Two vector organisms are ticks and mosquitoes. These two vector organisms transmit many well-known diseases. Through most of this essay, I will be explaining these two different organisms and the diseases that they carry.
First, I will be explaining deer ticks. Ticks are small spider-like organisms that attach themselves to a donor body. Male ticks are black. Females have a red abdomen and some black near the head. Adult ticks usually feed on deer but some times feed on humans accidentally. Deer ticks go through three life stages. The first stage is the larva. The larvae are small and tan colored. They usually feed on things like chipmunks, mice, and other small animals. Nymphs are a little bit larger than the larva. They are beige with a dark head. Nymphs usually feed on larger animals such as birds and raccoons. The adults vary in color depending if they are males or females. They usually feed on cats, dogs, and humans. Deer ticks are usually found in grassy woodland areas or wide open plains. Deer ticks are more common in the eastern U.S. than in the western U.S.
Mosquitoes are small insects that have a very thin body. Mosquitoes can be found anywhere except for Antarctica. There are about 170 different species of mosquitoes in all of North America. To grow, mosquitoes need a small area of stagnant water. Mosquitoes have been known to breed in fresh water, salt-water marshes, or water found in old tires or plastic containers. The mosquito life cycle has 4 significant stages. They go from eggs to larvae to pupae and finally to adult. Only female mosquitoes can bite. Male mosquitoes feed on mostly flower nectar. The females, however, require a blood meal to lay their eggs.
The Essay on Chameleons Organism Physiology
We know that an organism is anything that is living and can function by itself. This paper will help understand chameleons and how they have evolved to adapt to their surroundings. It will also discuss their physical features inside and out. Myths and facts will be revealed, as well as a few comparisons between sexes. Though there are many species of chameleons, everything discussed will be in ...
Deer ticks carry many diseases. Some deer ticks carry a disease known as Lyme Disease. Lyme Disease became known in 1975 in the town of Lyme, Connecticut. Many people began suffering from arthritis and having skin rashes on their body. Medical researchers soon found that deer ticks carry the disease. After a while, Lyme Disease became curable. A tick has to be attached to a donor body for 24 hours to transmit Lyme Disease. The first symptom that occurs after being bit by the tick is a small red rash at the sight of the bite. This rash expands and later might appear on different sights on the body. This red rash is known as erythema migrans. Erythema migrans can also cause fever, headache, stiff neck, and body ache. The next symptom that might occur is arthritis. Arthritis usually occurs after a few months of being infected. Some of the other symptoms include severe headache and paralysis of facial muscles. It is rare, but if Lyme Disease is not treated over a longer period of time, the victim my die.
West Nile Encephalitis is a disease that was seen first in the U.S. in 1999 when it infected 62 people and killed 7 of them. West Nile Encephalitis is caused by mosquitoes who originated in Africa. West Nile Encephalitis is an infection of the brain caused by the West Nile Virus, a virus found in Africa, Eastern Europe, and West Asia. It is a mystery how West Nile Encephalitis came to the U.S. Some of the possibilities are that infected birds migrated to the U.S. Another possibility is that an infected human traveled here and was bitten by a mosquito here, which then infected more and more people. The symptoms of West Nile Encephalitis are flu-like infections. These are very similar to the symptoms that occur from Lyme Disease.
Equine Encephalitis is a rare disease that is spread to horses and humans by infected mosquitoes. Equine Encephalitis can cause severe complications in the central nervous system and can sometimes result in death. Equine Encephalitis occurs only in a specific type of mosquito that feeds only on birds. This is transmitted to horses and humans by mosquitoes that feed on both birds and other mammals. About half the people who get infected die and the other half suffer severe brain damage.
The Essay on Mad Cow Disease People Infected Cows
For preventing the spread of mad cow disease worldwide. Years after it was supposedly vanquished, mad cow disease, the brain infection that kills cows and some people who eat them, is on a comeback. The disease has spread widely in Europe, and there are danger signs in the United States, where has never appeared. Mad cow disease is one of several fatal brain diseases called transmissible ...
There are many control measures taken for the preventing of mosquito bites and tick bites. One of the most common ways of preventing bites is by using the chemical permethrin. This chemical is better known as DEET. This chemical has many positive effects. It is very reliable because it is cheap and can be sprayed over fields with a low possibility of being seriously harmed. However, it also has some negative points. Permethrin is known to cause tremors, incoordination, elevated body temperature, and increased aggressive behavior. Permethrin is also toxic to many other organisms such as honeybees and fish. Another way we could protect ourselves from these insects is by applying insect repellents that do not contain DEET. This will not cause any harmful side effects, but may be less effective than applying DEET.
After closely examining the positive and negative aspects of ways to prevent bites, I am concluding that it is more reliable to use DEET rather than another chemical. Even though DEET may cause harmful side effects, it has never been known to permanently damage a person. This makes the use of DEET much more reliable.
