The answers may help clear the way for a new class of antibiotics For 50 years scientists have been unsure how the bacteria that gives humans cholera manages to resist one of our basic innate immune responses. That mystery has now been solved, thanks to research from biologists at The University of Texas at Austin. The answers may help clear the way for a new class of antibiotics that don't directly shut down pathogenic bacteria such as V. cholerae, but instead disable their defenses so...

Better than antibiotics, it is being used in contact lenses to prevent infections and biomedical products are the next stage The superbugs have met their match. Conceived at Nanyang Technological University (NTU), it comes in the form of a coating which has a magnetic-like feature that attracts bacteria and kills them without the need for antibiotics. The killer coating, which has shown to destroy 99 per cent of the bacteria and fungi that it comes in contact with, is now being used...

Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, known as mucins, on mucus membranes to enter and infect a part of the body. Their landmark study, published in the March 7, 2012 PLoS ONE, describes how they discovered that an "epidemic" strain of the bacterium Streptococcus pneumoniae, which causes conjunctivitis,...

Researchers from Boston University School of Medicine (BUSM) have for the first time identified a novel pathway that is necessary for infection to occur with the pathogen Neisseria gonorrhoeae, which is responsible for the second most common infectious disease worldwide, gonorrhea. The study, which was recently published online in the Journal of Bacteriology, may lead to new treatment methods for this sexually transmitted disease. N. gonorrhoeae is a pathogenic bacterium that readily...

The first awardees for the pilot project grant program from The Alkek Center for Metagenomics and Microbiome Research at Baylor College of Medicine have been announced. The grants were open to BCM instructors, assistant professors and postdoctoral associates. Six researchers were chosen for the Microbiota Association Discovery award of $20,000 or the Host-Commensal Interaction Study award of $50,000. "The grants were created to support preliminary studies for faculty who are looking to...

Escherichia coli bacteria thrive in the lower intestine of humans and other animals, including birds. Most are vital constituents of the healthy gut flora, but certain forms of E. coli cause a range of diseases in both humans and poultry. In this month´s issue of the journal PLoS ONE, a team of researchers at Arizona State University´s Biodesign Institute investigates disease-causing E. coli strains known as APEC (for Avian Pathogenic E. coli).  By studying circular segments...

Persistent bacterial infections can make a mess of our bowels and the usual treatment method of adding antibiotics usually causes even more disruptions. Researchers, however, are fine tuning a treatment that involves adding a sample of the stool of another which jump-starts the infected patients immune system, reports Kerry Grens for Reuters Health. The procedure is used primarily to treat patients with infections from the bacterium Clostridium difficile. “It´s unbelievably...

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...
