Researchers have developed the first animal model of the infection caused by chikungunya virus (CHIKV), an emerging arbovirus associated with large-scale epidemics that hit the Indian Ocean (especially the French Island of La RÃ©union) in 2005, later spreading to India, and Italy in 2007.
Few things sting like a mosquito's bite -- especially if that bite carries a disease such as malaria. If researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well.
ALBUQUERQUE - A group of researchers has discovered a mechanism that helps protect deer mice from hantavirus even though the rodents carry the life-threatening disease.

By Cathy Locke, The Sacramento Bee, Calif. Jul. 12--El Dorado County health officials are urging precautions in areas that may be infested by rodents after a resident contracted hantavirus pulmonary syndrome, a disease spread by rodents.
Mexicans have long been taught to blame diseases brought by the Spaniards for wiping out most of their Indian ancestors. But recent research suggests things may not be that simple.
Without mosquitoes, epidemics of dengue fever and malaria could not plague this planet. Eliminating the pests appears impossible. But scientists are attempting to re-engineer them so they cannot carry disease.
NEW YORK (Reuters Health) - Two cases of melioidosis, an infectious disease caused by the bacterium Burkholderia pseudomallei that is rare in the US, were reported to the Florida Department of Health in 2005.
CHICAG0 (Reuters) - Minnesota is grappling with its worst outbreak of livestock anthrax in 87 years, state officials said on Thursday.
An unusual number of dead jack rabbits in Texas has authorities concerned that so-called rabbit fever, or tularemia, could be making a comeback. The bacterial disease can infect humans but is rarely fatal.
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...
