The Dengue Virus, although virtually unknown in the United States, is prevalent in Latin America and Asia. It is also known as the breakbone fever. Transmitted by mosquitoes, the Dengue Virus causes rashes, headaches, and muscle pain. The hemorrhagic form of the virus may often cause death in the patient.
WHAT IS DENGUE FEVER?
(& Dengue Hemorrhagic Fever)
Dengue is a disease transmitted to humans by infected mosquitoes. The potentially fatal disease is caused by a group of four viruses that are mosquito born.
WHAT ARE THE FOUR DENGUE VIRUSES?
Dengue and Dengue Fever are caused by one of four virus serotypes: DEN-1, DEN-2, DEN-3, DEN-4. The four virus are closely related, however they are anitgenically distinct. Unfortunately, a person can have several dengue infections in their lifetime because a person does not become immune to the other three viruses if infected.
HOW IS DENGUE FEVER SPREAD?
Dengue fever is transmitted by mosquitoes who have been infected with the dengue virus. In the Western Hemisphere, the Aedes aegypti is the one mosquito species that transmits the disease. When a mosquito bites a person who has Dengue or Dengue Fever, the insect becomes infected and acts as a carrier of the virus. The disease spreads when mosquito-carriers bite healthy individuals who are now hosts for the virus. The Dengue virus is only spread by mosquitoes; it is not spread directly from person to person. The Aedes aegypti is a day-biting mosquito that prefers to feed on humans.
WHO GETS DENGUE FEVER?
Everyone is susceptible to the disease if exposed to infected mosquitoes. Dengue fever is a current epidemic in more than 100 subtropical countries where the mosquito population is high. These tropical regions inclu...

During the process of insertional mutagenesis, the plasmid vector contains another identifible gene, with the coding sequence of this gene containing the restriction site for insertion. Insertion of the foreign DNA at this site interrupts the reading frame of the gene and results in insertional mutagenesis.
A probe is used to detect the desired DNA during the audioradiography. Audioradiography is "the detection of a radioactive substance in a cell or organism by putting it in contact with a photographic emulsion and allowing the material to "take its own picture." The emulsion is developed, and the location of the radioactivity in the cell is seen by the presence of silver grains in the emulsion" (Purves, Orians, and Heller, G4).
What is the difference between a'smart' and a'smart'? Why was Anderson’s incompetence with language and household skills both a problem and a blessing for her work in Tarnby? Anderson’s incompetence with language and household problems were due to the translation and understanding of a new culture. Barbara’s confusion of flour with sugar caused her meat loaf to be a disaster. The two words are very similar in Denmark.
Therefore colonies containing the non-recombinant pUC19 plasmid have a functional lacz’ gene appear blue on the agar and colonies containing recombinant pUC19 would have a non-functional lacz’ gene due to insertional inactivation and appear white on the growing medium.

153 deaths have been associated with Chikungunya in the western hemisphere, stated by (Harvey, 2015). Mosquito-borne illnesses including Chikungunya has been prevalent in the Caribbean areas and is continuously spreading worldwide. Mosquito-borne diseases are virus that can only be transmitted through mosquitoes, which the virus can only be transmitted through a bite. Jamaica has encountered several mosquito-borne illnesses including Chikungunya, Malaria, and dengue. The name “chikungunya” is derived from a word in the Kimakonde language meaning “to become contorted” and describes the stooped appearance of sufferers with joint pain (Harvey, 2015). The virus has frequently been mistaken for dengue due to the similar signs and symptoms such as headache and joint pain. Joint pain, fever and vomiting are possible effects of Chikungunya in Jamaica.
The discovery of yellow fever would have not been possible if people had not put aside their misconceptions of where diseases originated. Diseases in olden time were believed to be divine punishment to people who had committed bad deeds, and therefore not much was done to try to find cures for diseases like yellow fever. As defined by the World Health Organization, yellow fever an acute viral hemorrhagic diseases transmitted by infected mosquitoes, and a common characteristic of this disease is the development of jaundice which gave it the name "yellow" fever. The mosquito responsible for the transmission of the disease is the female Aedes aegypti mosquito. Her transmission of the disease occurs as a result of it biting an infected host and inside her body the virus multiplies, and afterwards if the mosquito bites someone that person becomes infected.
Mosquitoes carried the diseases and when a person got bit he would give a disease to the mosquito and the mosquito would pass it on to the next victim ("Historical Overview").
The purpose of this experiment is to identify an unknown insert DNA by using plasmid DNA as a vector to duplicate the unknown insert DNA. The bacteria will then be transformed by having it take in the plasmid DNA, which will allow us to identify our unknown insert as either the cat gene or the kan gene.

A disease is transmitted in one way or the other. Lyme disease is transmitted through a vector. The vector of the disease is an infected deer tick. The deer tick has to bite a person to spread the disease. When a deer tick bites a person (sucks blood), the Borrelia burgdoferi bacteria is transmitted into the persons body.
The Disease Yellow Fever Throughout history, many different diseases have infected the world. Such diseases consist of measles, mumps, malaria, typhus and yellow fever. Many of these diseases are caused by different things and originated in different countries. Yellow fever is a deadly disease caused by a viral infection that is transmitted through the bite of an infected mosquito. Although it is found to be most common in males in their early 20's, yellow fever can affect any sex, race, or age.

Dengue fever, also known as the “breakbone fever”, is a vector-borne viral disease endemic in tropic and subtropic regions, with around 100 million symptomatic new cases each year worldwide15. It is caused by any one of the four closely-related serotypes or viruses that is spread by multiple species of mosquitoes, in particular the Aedes aegypti 6,13.
Dengue is an acute febrile viral disease transmitted by mosquitos. There are 4 antigenically distinct serotypes of dengue virus – DENV-1, DENV-2, DENV-3 and DENV-4. Each of the dengue virus serotypes is capable of causing severe dengue. Infection with one of the four serotypes of the dengue virus (DENV 1-4) can cause severe dengue and early viral burdens. Most of the dengue virus infections are asymptomatic while the rest result in a broad spectrum of disease that differs in severity from mild undifferentiated fever, i.e. the classical dengue fever (DF), to the potentially serious complications known as dengue haemorrhagic fever (DHF) an...
