Austria, Vienna Possessed By Feces-Contaminated Holy Water
2013-09-16 09:27:33

Michael Harper for redOrbit.com - Your Universe Online Holy water from Vienna and other parts of Austria has been found to be contaminated with fecal matter, according to a new study. This water is used in church ceremonies including baptisms and consecrating the lips of congregants. The researchers are now claiming the water from these “holy” fonts in Austria and Vienna is dangerous and is urging churches to issue a warning encouraging church members not to drink the water. The...

Helicobacter pylori is a bacterium that establishes a life-long stomach infection in humans, which in some cases can lead to duodenal ulcers or stomach cancer. New research, presented at this week's Society for General Microbiology Autumn Conference, gives us a clearer understanding of how these bacteria can manipulate the human immune system to survive in the mucosal lining of the stomach. Researchers from the University of Nottingham have shown that H. pylori is able to supress the...

Tracking Antibiotic Resistant Salmonella
2013-08-29 15:52:29

Peter Suciu for redOrbit.com – Your Universe Online Researchers at Penn State’s College of Agricultural Sciences are seeking to identify and track strains of antibiotic resistant bacteria as they evolve and spread. The goal is stop the spread of salmonellosis, an infection associated with the bacteria salmonella. Antibiotic-resistant strains of this bacteria are a major threat to public health, and the number of resistant strains is apparently increasing. Each year in the US, the...

The bacterium Pseudomonas aeruginosa needs iron to establish and maintain a biofilm in the lungs of cystic fibrosis patients, and therapies have been proposed to deprive the bacteria of this necessary element. However, these techniques may not work, according to a new study published in mBio®, the online open-access journal of the American Society for Microbiology, because they only target one of the two types of iron that are available in the lung. Current therapies focus on removing...

Mechanism By Which Beneficial Bacteria Reside And Thrive In The Gastrointestinal Tract Identified For The First Time
2013-08-19 15:44:43

Caltech The human body is full of tiny microorganisms—hundreds to thousands of species of bacteria collectively called the microbiome, which are believed to contribute to a healthy existence. The gastrointestinal (GI) tract—and the colon in particular—is home to the largest concentration and highest diversity of bacterial species. But how do these organisms persist and thrive in a system that is constantly in flux due to foods and fluids moving through it? A team led by California...

NASA Study Looks At How Spaceflight Affects Bacterial Social Networks

April Flowers for redOrbit.com - Your Universe Online Microorganisms are invisible to the naked eye. Healthy human adults have ten times as many microbial cells as human cells inside their bodies. Countless more microbes populate the environment around us, which means when astronauts launch into space, a microbial entourage follows. Communities of bacteria, known as biofilms, are often found attached to surfaces. The biofilms protect the bacteria with a slimy matrix they secrete. For...

Wolbachia is a genus of bacteria which infects arthropod species, including a high proportion of insects (~60% of species). It is one of the world's most common parasitic microbes and possibly the most common reproductive parasite in biosphere. Studies have suggested that 25-70% of all insect species are estimated to be potential hosts. Marshall Hertig and Burt Wolbach first identified the bacterium in 1924 in a species of mosquito. Hertig described the genus as Wolbachia pipientis. Not...

Serratia marcescens is a species of Gram-negative, rod-shaped bacterium in the family Enterobacteriaceae. S. marcescens is involved in nosocomial infections particularly catheter-associated bacteremia. It is commonly found in respiratory and urinarty tracts of hospitalized adults and often in the gastrointestinal system of children. It is commonly found growing in bathrooms due to its preference for damp conditions. It manifests as a pink discoloration and a slimy film feeding off...

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...

Rickettsia rickettsii is a gram-negative bacterium native to the New World and causes the malady known as Rocky Mountain spotted fever (RMSF). It is transmitted through the bit of an infected tick when it feeds on animals and humans. Humans are not necessary hosts in the rickettsia-tick life cycle but they can be. S. Burt Wolbach created the first detailed description of the etiologic agent in 1919. He recognized it as an intracellular bacterium seen most frequently in endothelial cells....

Pseudomonas aeruginosa is a common bacterium that can cause disease in animals and humans. It can be found in soil, water, skin flora, and most man-made environments throughout the world. It thrives in normal or hypoxic atmospheres; due to this it has colonized many natural and artificial environments. It can infect animals with damaged tissue or people with reduced immunity. Symptoms are generalized inflammation and sepsis. It can be fatal if colonization occurs in critical body organs,...
