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...

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...

Purdue University biologists identified a new way in which bacteria hijack healthy cells during infection, which could provide a target for new antibiotics. Zhao-Qing Luo, the associate professor of biological sciences who led the study, said the team discovered a new enzyme used by the bacterium Legionella pneumophila - which causes Legionnaires' disease - to control its host cell in order to take up residence. "Legionnaires' disease is a severe form of pneumonia, and this finding could lead...

Legionella experts give a stepwise approach to evaluate efficacy of disinfection methods. Authors recommend infection control practitioners lead environment of care team in choosing disinfection technologies; post-treatment followed by scheduled culturing for Legionella. Pittsburgh, PA (PRWEB) February 27, 2011 Legionnaires' disease outbreaks, caused by Legionella in hospital drinking water, can be prevented using the right disinfection methods. Too often hospitals make treatment...

40 percent to 60 percent of all cooling water systems tested contain Legionella--the bacterium that causes Legionnaires' disease. Nonchemical devices failed to control this bacterium in model cooling water towers according to an ASHRAE-funded study. Pittsburgh, PA (PRWEB) February 4, 2011 To avoid a potential health hazard, equipment operators, building owners, and engineers should monitor large cooling water systems that use nonchemical "green" devices to control Legionella, says Dr. Janet...

(Ivanhoe Newswire) -- A case report in this week's issue of The Lancet, investigates an unusual situation where a man contracted Legionnaire's disease through a cut in his hand while planting with potting compost. Legionnaire's disease is a common pneumonia that is typically caused by Legionella pneumophila. Legionnaire's disease caused by L longbeachae is much less common. There have only been nine reported cases of this kind in the United Kingdom since 1984. According to the Centers for...

Legionnaire's disease bacteria tap into the material transport in immune cells When it infects the lungs, the Legionnaire's bacterium Legionella pneumophila causes acute pneumonia. The pathogen's modus operandi is particularly ingenious: it infiltrates deliberately into cells of the human immune system and injects a host of proteins which then interfere in the normal cellular processes. Scientists from the Max Planck Institute of Molecular Physiology in Dortmund have now discovered how...

Four patients at an Arizona hospital were incorrectly diagnosed with Legionnaires' disease last year because of un-sterilized ice, health officials said. The Centers for Disease Control and Prevention's Mortality and Morbidity Weekly Report said unsterilized ice for bronchoscopies -- inspection inside the lungs using a flexible tube and video camera -- can transmit Legionella bacteria, which may lead to incorrect diagnosis. Investigators said ice from two machines that were connected to the...

At least six people at a New Jersey hospital have been diagnosed with Legionnaire's disease in the past two weeks, including one man who died. Marilyn Riley, a spokeswoman for the state Department of Health and Senior Services, said the victims -- three men and three women -- were patients at St. Peter's Hospital in New Brunswick, The Star-Ledger of Newark reported. They were all in the same part of the hospital and had damaged immune systems that made them vulnerable to infection....


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
