A rare outbreak of anthrax has killed 13 cows in Sweden, but is unlikely to harm people, says the country's Institute for Infectious Disease Control. The farm near Varberg in western Sweden has been quarantined and the remaining animals treated with antibiotics, which is effective against anthrax, said
Research conducted at The University of Queensland could contribute to the development of a vaccine and cure for West Nile virus and Dengue fever.
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.

U.S. entomologists say they've determined smaller mosquitoes are more likely to be infected with viruses causing human diseases than are larger mosquitoes.
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.
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.
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.
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.
Less is more, when it comes to giving fewer doses of the anthrax vaccine.
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 40Â°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...
