Migratory birds can spread haemorrhagic fever

A type of haemorrhagic fever (Crimean-Congo) that is prevalent in Africa, Asia, and the Balkans has begun to spread to new areas in southern Europe. Now Swedish researchers have shown that migratory birds carrying ticks are the possible source of contagion.

Researchers have now studied the dissemination mechanisms of this potentially fatal disease. The study is multidisciplinary, with bird experts, tick experts, molecular biologists, virologists, and infectious disease physicians from Uppsala University and Uppsala University Hospital in collaboration with colleagues from the Swedish Institute for Communicable Disease Control, Kalmar and Linköping. Ornithologists and volunteers also helped gather birds.

U.Va. Researchers Find Anthrax Can Grow and Reproduce in Soil

Anthrax has the unexpected ability to grow and reproduce while lurking in soil – increasing the deadly bacteria’s chances to infect cattle and other mammals, researchers at the University of Virginia School of Medicine have discovered.

Until now, experts have widely believed that anthrax spores remain dormant in soil until eaten by cattle, then germinate and cause the deadly disease. But U.Va. researchers have found that the spores can attack a common soil and water amoeba, Acanthamoeba castellanii, turning these single-celled organisms into anthrax incubators.

Antibiotic-Resistant Bugs Go Wild

One of the most notorious and hard-to-treat bacteria in humans has been found in wildlife, according to a new study in the Journal of Wildlife Diseases. The researchers isolated methicillin-resistant Staphylococcus aureus (MRSA) in two rabbits and a shorebird. Wild animals may act as an environmental reservoir for the disease from which humans could get infected.

...Now it appears that even animals in the wild can be infected with MRSA. Researchers led by epidemiologist Tara Smith of the University of Iowa's College of Public Health in Iowa City took samples from 114 animals that came into the Wildlife Care Clinic, which rehabilitates injured or orphaned animals, at Iowa State University in Ames. Seven of the animals, or 6.1%, carried S. aureus that was sensitive to methicillin; these included owls, pigeons, a beaver, a heron, and a squirrel. Three animals, or 2.6%, carried MRSA: two Eastern cottontail rabbits and a lesser yellowlegs, a migratory shorebird. (For comparison's sake: An estimated 1.5% of Americans carry MRSA in their noses.)
