New insights into a surprisingly flexible immune system present in bacteria for combating viruses and other foreign DNA invaders have been revealed by researchers from New Zealand's University of Otago and the Netherlands. A team led by Dr Peter Fineran of the Department of Microbiology and Immunology are studying the genetic basis of adaptive immunity in bacteria that cause potato 'soft rot' and in E. coli bacteria. Through their recent collaboration they have found that these bacterial...

When cannibals ate brains of people who died from prion disease, many of them fell ill with the fatal neurodegenerative disease as well. Likewise, when cows were fed protein contaminated with bovine prions, many of them developed mad cow disease. On the other hand, transmission of prions between species, for example from cows, sheep, or deer to humans, is—fortunately—inefficient, and only a small proportion of exposed recipients become sick within their lifetimes. A study published on...

The USDA confirms TeraGanix all natural liquid probiotic formula controls pathogen salmonella in poultry growing conditions. Peer reviewed research published in the Journal of Applied Poultry Research. Alto, TX (PRWEB) March 17, 2014 The pathogenic microorganism Salmonella is a concern for all poultry growers. Most food safety approaches utilize disinfectants and harsh chemicals to control pathogenic microorganisms. TeraGanix supplies an all-natural liquid product made of all...

M2 technology expands applications through massive increase in quantification with sample to answer in less than one hour SAN DIEGO, Feb. 28, 2014 /PRNewswire/ -- Menon Biosensors, Inc. a molecular biochemistry company providing DNA analysis for the diagnosis and treatment of biological pathogens, announced today that its M2 (Molecular Mirroring) NMR (nuclear magnetic resonance) technology successfully demonstrated quantification of pathogens having concentrations ranging from 1 CFU...

Pathogen Responsible For Two Historical Plagues Could Reemerge
2014-01-28 10:26:57

[ Watch the Video: Pathogen Behind Ancient Plagues Could Come Back Someday ] Brett Smith for redOrbit.com - Your Universe Online Both the Plague of Justinian in 541 and Black Death some 800 years later were responsible for widespread fatalities across Europe. Now, new research in The Lancet Infectious Diseases journal has found that both pandemics were caused by different strains of the same pathogen. The international team of study authors also concluded that a new strain of plague...

Medical Legacy Of Knut The Polar Bear
2014-01-03 08:03:07

Leibniz Institute for Zoo and Wildlife Research Keeping wild animals is an important component of the mission of zoos to educate the public and preserve endangered species. When animals die, tracking the potential cause becomes an investigation of pathogens from around the world. This is because zoo animals are not only potentially exposed to pathogens occurring where the zoo is located, but also to those pathogens harbored by other zoo animals. In other words: the diagnostic challenge is...

TB Bacteria Hide Their Identity To Invade Into Deeper Regions Of The Lungs
2013-12-20 14:30:54

University of Washington Cell surface lipids hide molecular patterns that infection-killing cells might recognize as dangerous TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host's body. Details on this finding are reported Dec. 16 in the advanced online edition of the journal...

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...

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,...

Probiotics May Help Keep Bad Germs At Bay
2013-11-04 08:38:08

Virginia Tech Microbes are everywhere – thousands of species are in your mouth, and thousands are in a glass of tap water. The ones in your mouth are mostly harmless – as long as you brush and floss so they don't form a biofilm that allows gum disease a path into the blood stream. Microbes in the tap water delivered by modern water systems in a developed country are also mostly harmless – with some notable exceptions. A team of Virginia Tech researchers is investigating the...
