Scientists have made an important advance in understanding how a subset of bacterial cells escape being killed by many antibiotics. Cells become "persisters" by entering a state in which they stop replicating and are able to tolerate antibiotics. Unlike antibiotic resistance, which arises because of genetic mutations and is passed on to later generations, this tolerant phase is only temporary, but it may contribute to the later development of resistance. In a new study in the journal...

The Center for Nutritional Research recommends bovine colostrum supplements to help neutralize bacterial pathogens recently detected in raw chicken breasts and to prevent potentially deadly illnesses caused by antibiotic-resistant superbugs. Sedona, AZ (PRWEB) December 23, 2013 According to a December Consumer Reports article, an analysis of more than 300 store-bought, raw chicken breasts showed that 97% of the samples contained illness-causing bacteria. The chicken breasts were purchased...

Epidemic Of E. Coli Infections Traced To One Strain Of Bacteria
2013-12-17 11:54:36

George Washington University School of Public Health and Health Services Fast-evolving lethal clone spreads worldwide, according to new study published today In the past decade, a single strain of Escherichia coli, or E. coli, has become the main cause of bacterial infections in women and the elderly by invading the bladder and kidneys, according to a study published today in the American Society for Microbiology's open access journal mBio. Besides becoming more resistant to...

Protein In Salmonella Jams Signals From Bacteria-fighting Mast Cells
2013-12-12 17:37:35

Duke University Medical Center A protein in Salmonella inactivates mast cells -- critical players in the body's fight against bacteria and other pathogens -- rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS). The study, conducted in mice, was published Dec. 12, 2013, in the journal Immunity. "Ever since mast cells were discovered to be critical mobilizers of the body's...

In a study of adults with severe bacterial meningitis, therapeutic hypothermia (reduction of body temperature) did not improve outcomes, and it may even have been harmful, according to a study appearing in the November 27 issue of JAMA. Among adults with bacterial meningitis, the case fatality rate and frequency of neurologic complications are high, especially among patients with pneumococcal meningitis. In animal models of meningitis, moderate hypothermia has shown favorable effects,...

RnRMarketResearch.com adds “EpiCast Report Gram-Negative Bacterial Urinary Tract Infection – Epidemiology Forecast to 2022” to its store. The report provides an overview of the risk factors and global trends of Urinary Tract Infection in the 7MM (US, France, Germany, Italy, Spain, UK, and Japan). Dallas, Texas (PRWEB) November 21, 2013 Urinary tract infections (UTIs) are among the most common bacterial infections acquired in hospitals and in the community setting (Foxman, 2010)....

Bacteria Use Lethal Cytotoxins In Order To Evade Antibiotic Treatment
2013-11-18 11:49:43

Aarhus University Bacteria that cause infectious diseases produce a number of cytotoxins, and an international research team has now found the mechanism behind one of these toxins. The new results could make it possible in the future to develop new treatment methods to impair the cytotoxic activity and thereby reduce the severity of infectious diseases. In spite of the fact that the first antibiotics were discovered almost a century ago, infectious diseases such as tuberculosis,...

New Treatment May End Dangerous MRSA Superbug Infections
2013-11-15 10:44:19

Rebekah Eliason for redOrbit.com – Your Universe Online One of the most significant health threats people face today is antibiotic resistant bacteria. A new study by Professor of Biology Kim Lewis presents a groundbreaking method for treating and eliminating the deadly bacterium methicillin resistant staphylococcus aureus, commonly known as MRSA. Referred to as a “superbug”, MRSA infects a staggering 1 million Americans every year. This bacteria is especially deadly as it leads to...

In Europe alone, more than 25,000 people die each year from infections caused by multi-resistant bacteria. Researchers from University of Copenhagen have now developed and characterized a substance that quickly and effectively kills the virulent bacteria. The substance employs a multifunctional mechanism that reduces the risk of antibiotic resistance. The findings have recently been published in the scientific journal Chemistry & Biology. Since WWII, antibiotics have made it possible...

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...
