Scientists have completed the most comprehensive comparative analysis to date of bacterial communities inhabiting the human nose and throat, which could provide new insights into why some individuals become colonized with pathogens while others do not. They release their findings today in mBioâ„¢ the online open-access journal published by the American Society for Microbiology."The nose and throat are important sites of pathogen colonization, yet the microbiota of both are relatively...
The discovery could help to design new strategies to increase their sensitivity to antibioticsA study led by researchers from Universitat Autònoma de Barcelona (UAB) describes one of the mechanisms in which pathogenic bacteria populations control the way they spread over the surface of the organs they infect and stop when they detect the presence of an antibiotic, only to resume again when the effect wears off. The star of this process is the RecA protein, which significantly increases its...
Unlocking the keys to H. pylori's helical structure may lead to better antibiotic drugs for diseases from ulcers and stomach cancer to diarrhea and choleraThe bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive "“ and thrive "“ within the stomach's acid-drenched environment, but until now...
CHAPEL HILL, N.C., May 13 /PRNewswire/ -- Cempra Pharmaceuticals today announced the schedule of poster presentations on its next-generation macrolide, CEM-101, at the American Thoracic Society (ATS) 2010 International Conference in New Orleans, Louisiana, on May 14 to 19, 2010. Both posters will be presented during the poster session entitled "C41 Emerging Pharmacology for Chronic Obstructive Pulmonary Disease: Mechanisms and Outcomes" scheduled for 8:15 a.m. to 4:00 p.m. CDT on Tuesday,...
Pathogenic bacteria in the gut recognize their surroundings by detecting hormone signals from the host, which can prompt them to express lethal toxins. Intercepting these hormonal messages could be a better way to treat serious food-borne infections where antibiotics do more harm than good, explains Vanessa Sperandio speaking at the Society for General Microbiology's spring meeting in Edinburgh on Sunday.Gut bacteria, including harmful strains of Escherichia coli and Salmonella that cause...
HAYWARD, Calif. and SHANGHAI, March 15 /PRNewswire/ -- MicuRx Pharmaceuticals, Inc., a privately-held biopharmaceutical company developing next-generation antibiotics, today announced that it has filed an Investigational New Drug (IND) application with the State Food and Drug Administration (SFDA) in China for MRX-I, its first development-stage antibiotic drug candidate. MRX-I, an orally-administered oxazolidinone, targets multi-drug resistant Gram-positive bacteria including...
CHAPEL HILL, N.C., Oct. 29 /PRNewswire/ -- Cempra Pharmaceuticals today announced a presentation on its novel fluoroketolide antibiotic, CEM-101, at the Infectious Diseases Society of America, 47th Annual Meeting, October 29 to November 1, 2009, in Philadelphia. Susceptibility of CEM-101 and more than 25 other antibiotics was tested against 1,737 multidrug-resistant S. pneumoniae strains collected in 2008 from medical centers in the U.S., Europe and Latin America. CEM-101 demonstrated 100%...
Unexpected research findings show resource managers and researchers may have to rethink how they determine if water will make people sick.Bacteria commonly used to indicate health risks in recreational waters might not be so reliable after all. Pathogenic E. coli were pervasive in stream-water samples with low concentrations of fecal indicator bacteria. This is one of the unexpected findings from recent research that may affect how researchers and resource managers rely on indicator bacteria...
University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium.Listeria monocytogenes is a bacterium that can cause pregnant women to lose their fetuses and trigger fatal cases of meningitis in the elderly or people with compromised immune systems. The bacterium has been linked to outbreaks traced to food processing plants in the U.S. and Canada.In 2002, a multi-state...

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...
