Our Immune System May Actually Help Staph Bacteria Thrive: Study
2013-11-21 07:48:52

Ranjini Raghunath for redOrbit.com - Your Universe Online Staphylococcus aureus, one of many strains of bacteria involved in Staph infections, is found in about 20 percent of all humans. Under normal conditions, the bacterium dwells harmlessly in the skin or nasal passages, occasionally causing food poisoning or mild skin infections. When it enters the bloodstream, however, it can be quite deadly, causing life-threatening illnesses such as meningitis or sepsis. One of the ways the...

A new method could cut hours off the time it takes to diagnose blood infections while also eliminating the need for complicated manual processing and expensive equipment, according to a report to be published in mBio®, the online open-access journal of the American Society for Microbiology, on November 19. The method combines a selective lysis step in which blood cells in the sample are destroyed, a centrifugation step to collect any bacteria or fungi in the sample, and a fluorescence step...

Bacteria recycle broken DNA that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resistance to antibiotics in hospitals and in our perception of the evolution of life itself. Our surroundings contain large amounts of strongly fragmented and damaged DNA, which is being degraded. Some of it may be thousands of years old. Laboratory experiments with...

Two billion years ago the Earth system was recovering from perhaps the single-most profound modification of its surface environments: the oxygenation of the atmosphere and oceans. This led to a series of major changes in global biogeochemical cycles, as a team around Aivo Lepland of the Norwegian Geological Survey NGU reports in the latest online edition of "Nature Geoscience". This also resulted in the distribution of one of life's key elements, phosphorous. Studies on the unique...

ATLANTA, Nov. 18, 2013 /PRNewswire/ -- Princeton University announced plans for the use of Bexsero® meningococcal B vaccine in response to the meningococcal disease outbreak at the University. The National Meningitis Association (NMA) supports this collaborative public health effort that will help protect those at Princeton during this time of high-risk for the infection. Quick Facts about Meningococcal Disease and Vaccination -- Meningococcal disease, which is sometimes called...

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,...

Yersinia enterocolitica is a species of gram-negative coccobacillus-shaped bacterium, belonging to the family Enterobacteriaceae. Infection from Yersinia enterocolitica causes the zoonotic disease yersiniosis. Most infected animals recover from the disease and become asymptomatic carriers. Acute infections lead to mild self-limiting entero-colitis or terminal ileitis in humans. Symptoms include watery or bloody diarrhea and fever. After oral uptake it replicates in the terminal ileum and...

Vibrio vulnificus is a species of Gram-negative, motile, curved, rod-shaped bacteria of the Vibrio Genus. Hollis et al. first reported it in 1976. It was given the name Beneckea vulnifica by Reichelt et al. in 1976 and in 1979 Vibrio vulnificus by Farmer. V. vulnificus is related to V. cholerae and is present in marine environments such as estuaries, brackish ponds, or coastal areas. It causes an infection often incurred after eating seafood, especially raw or undercooked oysters. It can...

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...

Streptococcus mutans is a Gram-positive cocci, Facultative anaerobic bacterium commonly found in the human oral cavity and is a significant contributor to tooth decay. J Kilian Clarke first described the microbe in 1924. The first colonizers of the tooth surface are mainly Neisseria spp. and streptococci, including S. mutans. The pioneer species changes the local environmental conditions through growth and metabolism thus allowing more fastidious organisms to further colonize after them,...

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...
