New research from Lund University casts new light on the interaction between the immune system and streptococcus bacteria, which cause both mild tonsillitis and serious infections such as sepsis and necrotising fasciitis. The way in which antibodies attach to the bacteria is linked to how serious the disease is. Antibodies are key to the recognition and neutralization of bacteria by our immune system. The most common antibodies have the shape of a Y, and the two prongs fasten to molecules...

Scientists have engineered bacteria that are capable of sacrificing themselves for the good of the bacterial population. These altruistically inclined bacteria, which are described online in the journal Molecular Systems Biology, can be used to demonstrate the conditions where programmed cell death becomes a distinct advantage for the survival of the bacterial population. "We have used a synthetic biology approach to explicitly measure and test the adaptive advantage of programmed...

New results from tests performed by Consumers Union suggest that antibiotic resistant E. coli is present in more than half of all store-bought chicken. Concerned families scramble to protect themselves from bacteria with alternative treatment methods like NutraSilver Plus. Reno, NV (PRWEB) October 11, 2012 Test results submitted by Consumers Union have found that grocery store shelves are littered with contaminated chicken. Tests show that as much as two-thirds of grocery store chicken...

Dr. Russell Russo, an Orthopedic Surgeon at LSU Health Sciences Center New Orleans, and other researchers stress that orthopedists should have a high index of suspicion for necrotizing fasciitis, or flesh-eating bacterial infection, in every patient with pain or other symptoms that are out of proportion to the initial diagnosis. Their recommendations are published in the September 2012 issue of Orthopedics Today. Although relatively rare and difficult to diagnose because its symptoms often...

Having healthy gut bacteria could have as much to do with a strategy that insurance companies use to uncover risk as with eating the right foods, according to researchers at the University of East Anglia (UEA). Findings published today in Ecology Letters show how researchers applied a strategy used by insurance companies to understand how animals and plants recruit beneficial bacteria. The breakthrough brings scientists closer to understanding the human body's relationship with...

Scientists at the University of Liverpool have found that the worm which causes River Blindness survives by using a bacterium to provide energy, as well as help 'trick' the body's immune system into thinking it is fighting a different kind of infection. River Blindness affects 37 million people, mainly in sub-Saharan Africa, causing intense itching of the skin, visual impairment and in severe cases, irreversible blindness. It is caused by a parasitic worm that is transmitted by...

Streptococcus pneumoniae, or pneumococcus, is Gram-positive, alpha-hemolytic, bile-soluble aerotolerant, anaerobic member of the genus Streptococcus. It was recognized as a major cause of pneumonia in the late 19th century and is thus the subject of many humoral immunity studies. It causes many other types of pneumococcal infections other than pneumonia including acute sinusitis, otitis media, meningitis, bacteremia, sepsis, septic arthritis, peritonitis, cellulites, and brain abscess. It...

Staphylococcus epidermidis is one of thirty-three known species belonging to the genus Staphylococcus. It is part of our skin flora and can also be found in the mucous membranes and in animals. It is the most common species found in laboratory test due to contamination. It is not usually pathogenic; however, patients with a compromised immune system often risk infection. Infections can be both nosocomial and community acquired and are more of a threat to hospital patients. Hospitals carry...

Staphylococcus aureus is a facultative anaerobic gram-positive coccus, and is the most common cause of staph infections. It is commonly part of the skin flora found in the nose and on skin. Around 20% of the human population is long-term carriers. It gets its golden color due to its carotenoid pigment staphyloxanthin. The pigment acts as a virulence factor with an antioxidant action that allows the microbe to evade death by reactive oxygen species used by the host immune system. Staphylococci...

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...

Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...
