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...

U.S. Researchers reported on Tuesday that a type of bacteria only recently revealed as a major cause of ulcers and stomach cancer may help protect children from developing asthma. Helicobacter pylori, a bacterium that has co-existed with humans for at least 50,000 years, may lead to peptic ulcers and stomach cancer, but children between the ages of 3 and 13 who carried the bug were 59 percent less likely to have asthma than uninfected children, they reported. "Our findings suggest that...

By Eric Eyre Staff writer Three Kanawha County residents have contracted Legionnaires' disease in recent weeks, the county's health director said Tuesday. A woman has died, and another woman and a man were in intensive care units in local hospitals, said Dr. Kerry Gateley, executive director of the Kanawha-Charleston Health Department. Tests confirmed that the patients contracted the Legionella bacteria that cause Legionnaires' disease, Gateley said. Health department officials have...

Daniel Burd is doing more than his part to help the environment. The Canadian teen has come up with an innovative plan to dispose of the plastic bags that cities and countries around the world are starting to ban."We like these conveniences and we sometimes don't even consider these effects on our earth," Burd told Reuters. "We don't have a spare world in our back pocket."During a science project that won him a $9800 first place prize in the Canada-Wide Science Fair, the Waterloo, Ontario,...

Nearly 100 percent drop in Hib meningitis as a result of widespread vaccinationHib meningitis has been virtually eliminated in young children in Uganda just five years after the country introduced Haemophilus influenza type b (Hib) vaccine nationwide, according to an independent study.Haemophilus influenza type b is a leading cause of pneumonia and meningitis, an inflammation of the lining covering the brain and spinal cord. Each year, Hib kills approximately 400,000 children under five years...

Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...

Neisseria meningitidis is a heterotrophic gram-negative diplococcal bacterium best known for its role in meningitis and other forms of meningococcal disease such as meningococcemia. It is a major cause of morbidity and mortality during childhood in industrialized countries and is responsible for epidemics in Africa and in Asia. In the US there are approximately 2500 to 3500 cases of N. meningitides infections. Children under 5 are at a higher risk as well as people in the sub-Saharan...

Helicobacter pylori is a Gram-negative, microaerophilic bacterium that can inhabit various areas of the stomach, particularly the antrum. It causes low-level inflammation of the stomach lining and is linked to gastric ulcers and stomach cancer. Out of those infected, 80%, are asymptomatic. It was initially named Campyloacter pyloridis and then renamed C. pylori to correct the Latin grammar error. It was later placed in the genus, Helicobacter. Over 50% of the population has H. pylori in...

Haemophilus influenzae is a Gram-negative, rod-shaped bacterium first described in 1892 by Richard Pfeiffer during an influenza pandemic. It is generally aerobic but can grow as a facultative anaerobe. H. influenzae was mistakenly considered to be the cause of influenza until 1933 when the flu virology became apparent. It was the first free-living organism to have its entire genome sequenced. The project was completed and published in 1995. Two major categories were defined: the...

Haemophilus ducreyi is a fastidious gram-negative coccobacillus causing the sexually transmitted disease chancroid, a major cause of genital ulceration in developing countries characterized by painful sores on the genitalia. Early symptoms are dark and light green shears in excrement. Chancroid starts as an erythematous popular lesion that breaks down into a painful bleeding ulcer. It can be cultured on chocolate agar. It is an opportunistic microorganism that infects through the...
