A 2010 outbreak of Legionnaires' disease in Wisconsin has been linked to a decorative fountain in a hospital lobby, according to a study published in the February issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. When the outbreak of Legionnaires' disease was detected among eight people in southeast Wisconsin, state and local public health officials worked closely with hospital staff to launch an investigation to...

Researchers are slowly creating a blueprint for the molecular machine that keeps the pathogen alive and well in the acidic stew of the guts of half the world's population A research team led by scientists at the Chinese University of Hong Kong is releasing study results this week showing how a bacterium, Helicobacter pylori, that causes more than half of peptic ulcers worldwide and that has been implicated in stomach cancer has managed for eons to turn the acidic environment of the human...

Results in 'Science' could identify new ways to design vaccines, antibiotics A University of Louisville scientist has determined for the first time how the bacterium that causes Legionnaires´ disease manipulates our cells to generate the amino acids it needs to grow and cause infection and inflammation in the lungs. The results are published online today (Nov. 17) in Science. Yousef Abu Kwaik, Ph.D., the Bumgardner Endowed Professor in Molecular Pathogenesis of Microbial Infections...

Current recommendations for testing missed 41 percent of cases A new study from Rhode Island Hospital shows that guidelines concerning testing patients for possible community-acquired pneumonia due to Legionella may underestimate the number of cases being seen by clinicians. The study found that if testing was only done in patients felt to be at increased risk of Legionnaires' disease based on such guidelines, more than 40 percent of Legionella cases could be missed based on this...

(Ivanhoe Newswire) — Gonorrhea has evolved into an antibiotic-resistant form, and urgent action is needed to combat this public health threat, according to this study. Gonorrhea, a sexually transmitted disease (STD) that causes pelvic inflammatory disease and urethritis, is evolving into multiresistant bacteria because most treatments are now ineffective. Japan reported the first example of multiresistant gonorrhea. Neisseria gonorrhea, the organism responsible, can mutate rapidly...

The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics, says a team of physicists and microbiologists at the University of Massachusetts Amherst. Their findings reported in the Aug. 7 advance online issue of Nature Nanotechnology may one day lead to cheaper, nontoxic nanomaterials for biosensors and solid state...

(Ivanhoe Newswire) -- In the largest study of its kind, researchers say different populations of people need different therapies to get rid of H. pylori, which is the primary cause of gastric cancer. According to the International Agency for Research on Cancer, stomach cancer was the fourth most common cancer and the second-leading cause of cancer death in the world in 2008. About 72 percent of new cases occur in developing countries. The current study, which was conducted at seven sites...

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...
