Drug-Resistant Malaria Spreading, Say Experts
2012-04-08 06:03:37

Scientists have expressed concerns that resistance to the primary treatment for malaria is increasing, potentially putting thousands of additional people at risk of losing their lives to the disease, according to various media reports. According to Brendan Trembath of ABC News Australia, lead researchers Francois Nosten, a researcher at the Shoklo Malaria Research Unit in Thailand, and colleagues reported that they had discovered drug-resistant strains of the Plasmodium falciparum parasite...

Changes promote blood-feeding behavior and virus transmission Mosquitoes infected with dengue virus experience an array of changes in the activity of genes and associated functions of their salivary glands, and these changes may lead to increased virus transmission, according to a recent study led by George Dimopoulos, Ph.D., of the Malaria Research Institute and Bloomberg School of Public Health at Johns Hopkins University. Some of these changes involve the mosquito's immune system and...

Researchers at the Johns Hopkins Bloomberg School of Public Health have, for the first time, shown that infection with dengue virus turns on mosquito genes that makes them hungrier and better feeders, and therefore possibly more likely to spread the disease to humans. Specifically, they found that dengue virus infection of the mosquito's salivary gland triggered a response that involved genes of the insect's immune system, feeding behavior and the mosquito's ability to sense odors. The...

[ Watch the Video ] Repellant overwhelms their odor sensors, scaring them away In a small, narrow, temperature-controlled lab room at Vanderbilt University live some of the most deadly and dangerous animals in the world. "These are Anopheles mosquitoes that still think that they're in Central Africa. We won't tell them any different," says Laurence Zwiebel, professor of molecular biology and pharmacology. Anopheles gambiae mosquitoes can be killers. In warmer climates, the...

The black saddlebags (Tramea lacerate) is a species of skimmer dragonfly that can be found in North America. It prefers to reside near still water sources like ponds and ditches. This species reaches an average body length of 1.9 inches and holds a thin body that is black in color, although females may hold light mottled markings along the body. The head on both males and females is wide and brown in color. The dark markings that occur on base of the hind wings have given it the common name,...

The chalk-fronted corporal (Ladona Julia) is a species of dragonfly that can be found in southern areas of Canada and northern areas of the United States. Young individuals of this species are typically reddish-brown in color with a black stripe occurring along the back and white stripes occurring along the shoulders. As young individuals develop, they change colors, with females becoming almost completely brown with some grey markings. Males develop white pruinescence markings along the base...

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...

Aedes albopictus (Family Culicidae), the Asian Tiger Mosquito or Forest Day Mosquito, is characterized by its black and white striped legs and small, black and white body. It was native to south-east Asia, and occupied a habitat that spread from Madagascar eastward to New Guinea, and north to the latitude of Korea. The typical member of the Aedes albopictus has a length of about 5 mm. As with other members of the mosquito family, the female is outfitted with an elongated proboscis that she...

The crane flies (Tipulidae) are a family of insects that closely resemble giant mosquitoes. Like the mosquito, they are in the order Diptera (flies) and are sometimes called mosquito eaters, mosquito hawks, or skeeter eaters. They are also one of three unrelated arthropods named Daddy long-legs. The other two are the harvestmen and vibrating, cellar or house spider. As such, Crane Flies are wrapped up in the myth of being the most poisonous spider, but unable to bite humans. This is...
