A Kansas State University epidemiologist is helping cats, pet owners and soldiers stay healthy by studying feline tularemia and the factors that influence its prevalence. Ram Raghavan, assistant professor of diagnostic medicine and pathobiology, and collaborative researchers have found that a certain combination of climate, physical environment and socio-ecologic conditions are behind tularemia infections among cats in the region. More than 50 percent of all tularemia cases in the U.S....

By Richard Harth, The Biodesign Institute A powerful new class of therapeutics, known as recombinant attenuated Salmonella vaccines (RASV), holds great potential in the fight against fatal diseases including hepatitis B, tuberculosis, cholera, typhoid fever, AIDS and pneumonia. Now, Qingke Kong and his colleagues at the Biodesign Institute at Arizona State University, have developed a technique to make such vaccines safer and more effective. The group, under the direction of Dr. Roy Curtiss,...

Finding may offer future alternative to antibiotics A team of scientists from government, academia and private industry has developed a novel treatment that protects mice from infection with the bacterium that causes tularemia, a highly infectious disease of rodents, sometimes transmitted to people, and also known as rabbit fever. In additional experiments with human immune cells, the treatment also demonstrated protection against three other types of disease-causing bacteria that, like the...

Immunologists at the University of Pittsburgh School of Medicine and Children's Hospital of Pittsburgh of UPMC and the have found a unique quirk in the way the immune system fends off bacteria called Francisella tularensis, which could lead to vaccines that are better able to prevent tularemia infection of the lungs. Their findings were published today in the early, online version of Immunity. F. tularensis is an intracellular pathogen that infects cells in the lungs called macrophages,...

U.S. researchers said on Thursday they have developed an antibiotic that works by blocking the communication signals of serious stomach bugs like salmonella, keeping them from releasing toxins that make people sick. Dr. Vanessa Sperandio of the University of Texas Southwestern Medical Center said the sensors in bacteria are waiting for the right signal to initiate the expression of virulent genes. Sperandio and colleagues found a compound named LED209, that disarms the bacteria instead...

Scientists hope a vaccine is on the horizon for tularemia, a fatal disease caused by the pathogen Francisella tularensis, an organism of concern as a potential biological warfare agent. Until recently we knew very little about this bacterium. However, according to the August issue of the Journal of Medical Microbiology, research on the bacterium has been reinvigorated and rapid progress has been made in understanding how it causes disease. Infection with F. tularensis can result in a variety...

WASHINGTON (Reuters) - Small amounts of a bacteria that causes "rabbit fever" were found on Washington's National Mall last weekend as thousands of protesters marched against the Iraq War, U.S. health authorities said on Saturday. The U.S. Centers for Disease Control and Prevention said several government environmental air monitors in the Mall area detected low levels of Francisella tularensis bacteria that cause Tularemia, commonly known as rabbit fever, on September 24-25. Public...

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...
