Research conducted at The University of Queensland could contribute to the development of a vaccine and cure for West Nile virus and Dengue fever. Led by Associate Professor Alexander Khromykh, a team of researchers from UQ's School of Molecular and Microbial Sciences identified a novel characteristic of the virus family to which these diseases belong. The team found all flaviviruses produced a small molecule which, among other functions, controlled the host's response to viral infection....

Air travel, international trade and globalized food production are helping "airport malaria" and other diseases spread to the United States, researchers say. Dr. James H. Diaz of Louisiana State University said airport malaria is transmitted when a mosquito infected with the disease bites a human within the vicinity of an international airport. Climate changes in some U.S. cities with a large presence of international air traffic, such as New York and Los Angeles, seem to have created a...

U.S. entomologists say they've determined smaller mosquitoes are more likely to be infected with viruses causing human diseases than are larger mosquitoes. The researchers said they fed mosquitoes blood contaminated with the dengue virus and later tested them for infection at the Florida Medical Entomology Laboratory, taking into account the size of each mosquito by measuring the length of their wings. They discovered smaller-sized mosquitoes had higher infection rates and greater...

An entomologist at the Illinois Natural History Survey, a division of the new UI Institute for Natural Resource Sustainability, says smaller mosquitoes are more likely to be infected with viruses that cause diseases in humans. These findings can be found in the November issue of the American Journal of Tropical Medicine and Hygiene. Barry Alto, Ph.D., Director of the Medical Entomology Program at the Illinois Natural History Survey, along with Assistant Professor Michael Reiskind of Oklahoma...

Popular media coverage of infectious diseases greatly influences how people perceive those diseases, making them seem more dangerous, according to a new study from McMaster University. The research, published online in the Public Library of Science: ONE, suggests diseases that show up frequently in the print media "“like bird flu "“are considered more serious than similar diseases that do not receive the same kind of coverage, such as yellow fever. "The media tend to focus on rare...

Syntiron announced today that it was notified of a pending contract from the Defense Threat Reduction Agency (DTRA) to adapt Syntiron's licensed, patented vaccine technology to combat three major bioterrorism agents; Bacillus anthracis, Yersinia pestis, and Burkholderia pseudomallei. The amount of the contract is $3.8 million dollars. Bacillus anthracis: A non-contagious, potentially fatal disease, commonly referred to as anthrax, caused by breathing, eating, or absorbing through cuts in...

New Hampshire health officials say Eastern equine encephalitis has been found in mosquitoes captured in Manchester. The Manchester Health Department said mosquitoes collected Sept. 29 tested positive for the virus. Eastern equine encephalitis can cause high fever and a severe headache. In the severe form of the disease, a stiff neck is a common symptom before seizures and coma, and it can lead to death. No one has tested positive for the disease in the state this year. The Associated...

Less is more, when it comes to giving fewer doses of the anthrax vaccine. Researchers said Tuesday the vaccine protects a person just as well from the bacteria that cause the disease, which could extend limited supplies of the shots. Members of the U.S. military are among those getting the vaccine made by Maryland-based Emergent BioSolutions, because anthrax can be used as a biological weapon. Conrad Quinn, of the U.S. Centers for Disease Control and Prevention and colleagues studied 1,005...

Roundup: Scientists urged to jointly tackle Africa's health issues By Daniel Ooko NAIROBI, Sept. 20 (Xinhua) -- Climate and health experts are warning that scientists must work together to tackle myriad African problems or risk disastrous consequences to human and animal health in the continent. Faced with the prospect of more variable and changing climates increasing Africa's already intolerable disease burden, experts warned that scientists must begin to reach out to colleagues in...

Francisella tularensis is a pathogenic species of gram-negative bacteria and the causative agent of tularemia or rabbit fever. It is a facultative intracellular bacterium. It is classified as a Class A agent by the U.S. government due to its ease of spread by aerosol and its high virulence. In 1911 the species was found in ground squirrels in California. There are four subspecies that have been classified. Biovar tularensis is found mostly in North America. Biovar palearctica is found...

Burkholderia pseudomallei is a Gram-negative, bipolar, aerobic, motile rod-shaped bacterium. It causes the disease melioidosis in humans and animals and is also capable of infecting plants. The bacteria can from in a number of artificial environments. Optimal temperature is around 40°C in pH-neutral or slightly acidic environments. Most strains can ferment sugars without gas formation. The bacteria produces both exo and endo toxins although the role of these toxins has not been fully...

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...

Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE). It can affect all equine species, such as horses, donkeys, and zebras. Equines may suddenly die or show progressive central nervous system disorders after infection. It is contractible by humans and will usually experience flu-like symptoms when infected. People with a weak immune system can become seriously ill or die. It is transmitted primarily...

Rinderpest (also cattle plague) is an infectious viral disease of cattle, domestic buffalo, and some species of wildlife. It is characterized by fever, oral erosions, diarrhea, lymphoid necrosis, and high mortality. The last confirmed case was in 2001. In 2011 it should be announced that a global eradication of rinderpest was complete. The term comes from the German language meaning cattle-plague. The rinderpest virus is closely related to measles and canine distemper viruses. It is a...
