The strain of cholera that has sickened thousands in Haiti came from a single source and was not repeatedly introduced to the island over the past three years as some have thought, according to a new study published in mBio®, the online open-access journal of the American Society for Microbiology. The results of this latest study are consistent with earlier findings that indicate Vibrio cholerae bacteria were introduced to Haiti by United nations soldiers between July and...

Mosquitoes Lose Their Sense Of Smell After Genetic Mutations
2013-05-30 05:45:43

April Flowers for redOrbit.com - Your Universe Online Researchers at the Howard Hughes Medical Institute (HHMI) have altered the way insects respond to odors, including the smell of humans and the insect repellant DEET, in one of the first successful attempts at genetically engineering mosquitoes. The findings, published in an issue of Nature, demonstrates that mosquitoes can be genetically manipulated using the latest research techniques. The results also pave the way to understanding...

A new diagnostic test for a worm infection that can lead to severe enlargement and deformities of the legs and genitals is far more sensitive than the currently used test, according to results of a field study in Liberia, in West Africa, where the infection is endemic. The new test found evidence of the infection — lymphatic filariasis — in many more people that the standard test had missed. The study, the first to independently evaluate the new test, was led by researchers...

A new article in The Journal of Parasitology features a study on schistosomiasis vaccine research. The researchers hypothesized that attacking ESP-induced immune responses would lead to almost total elimination of the parasite. Lawrence, KS (PRWEB) April 25, 2013 Nearly 800 million people, mostly children, are at risk for schistosomiasis, a widespread parasitic disease found in more than 75 developing countries. Although drug treatment is effective, it does not prevent reinfection. Research...

Strain is evolving to be more like virulent 1800s cholera The cholera strain that transferred to Haiti in 2010 has multiple toxin gene mutations that may account for the severity of disease and is evolving to be more like an 1800s version of cholera, reports a new Northwestern Medicine study. The strain, "altered El Tor," which emerged around 2000, is known to be more virulent and to cause more severe diarrhea and dehydration than earlier strains that had been circulating since the...

Researchers have discovered that rising temperature induces key changes in the dengue virus when it enters its human host, and the findings represent a new approach for designing vaccines against the aggressive mosquito-borne pathogen. The researchers found that the dengue virus particles swell slightly and take on a bumpy appearance when heated to human body temperature, exposing "epitopes," or regions where antibodies could attach to neutralize the virus. The discovery is significant...

Drug may be major advance as malaria has developed resistance to existing treatments Scientists at Oregon Health & Science University and the Portland VA Medical Center have developed a drug that may represent one of the world's best hopes for treating and preventing malaria – a disease that kills more than one million people each year. The scientists have described the drug, and its effectiveness against mice infected with malaria, in the March 20 issue of Science...

Tapeworm Genome Could Provide Targeted Drug Therapies
2013-03-14 05:20:14

April Flowers for redOrbit.com - Your Universe Online A research team, led by the Wellcome Trust Sanger Institute, has mapped the genome of tapeworms to reveal potential drug targets for existing drugs. Urgently needed and effective treatments for the debilitating diseases caused by tapeworms could be developed from the new information the genome provides. Two of the World Health Organization's (WHO) 17 neglected tropical diseases are caused by tapeworms: echinococcosis and...

Giant Roundworm, Ascaris lumbricoides
2014-01-12 00:00:00

The giant roundworm (Ascaris lumbricoides) is a parasitic worm within the Nematoda phylum. This species can be found throughout the world, but occurs in higher numbers in tropical and subtropical areas. It causes the disease known as ascariasis in its human hosts and infects about one quarter of the entire world’s human population. It displays a sexual dimorphism, with females growing larger than males. Females reach an average body length between 7.8 and 19.2 inches, while males reach a...

Wuchereria bancrofti
2014-01-12 00:00:00

Wuchereria bancrofti is a species of roundworm in the Nematoda phylum. This species is spread through a mosquito vector, which means that it is transferred through mosquitos. This species infects over 120 million people in South America, Africa, and other tropical and subtropical areas. It is one of three species of parasitic worm that can cause lymphatic filariasis, which can lead to elephantiasis. The disease is wrongfully named, because the term translates to “a disease caused by...

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...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...
