Lack of cytokeratin 6A may lead to eye infections

Exposed tissue surfaces, including skin and mucous membranes, are under constant threat of attack by microorganisms in the environment. The layer of cells that line these areas, known as epithelial cells, are the first line of defense against these pathogens, but the underlying molecular mechanisms that allow them to repel microbes are unknown.

NUI Galway project hopes to deliver cost effective tool for rapid diagnosis of pneumonia

Researchers at NUI Galway are involved in a new European project which hopes to deliver a cost effective tool for the speedy diagnosis of infections such as pneumonia. The test would reduce diagnosis time from days to hours, so that the appropriate treatments can be administered as early as possible for the best possible outcome.

FibeBiotics aims to prove benefits of polysaccharides in clinical trials

Staying healthy requires constantly stimulating the immune system. Ingesting non-digestible fibres such as polysaccharides is thought to help. Yet companies including such ingredients in their food products cannot claim that they boost the immune system. At least, not until they have been scientifically tested and proven in clinical trials. Only then, would the European Food Safety Agency (EFSA) allow such health claims.

UCSB researcher hopes to find out contaminants in urban water environment

What contaminants lurk in the urban subsurface, and what happens to them once they're there? Do they make their way into storm drains and creeks to reach groundwater, or even oceans? Or do they naturally attenuate as they migrate through soils, somehow allowing them to self-cleanse as they travel? A UC Santa Barbara researcher hopes to find out, thanks to a generous new gift to fund her work.

BioDiem granted European patent for antimicrobial drug

Australian vaccine development company BioDiem Ltd (ASX: BDM) announced today the successful granting of a key European patent for its synthetic antimicrobial compound BDM-I. BDM-I is a novel compound active against a range of pathogenic micro-organisms including bacteria, fungi and protozoa. The patent provides protection around BDM-I as a treatment for vulvovaginitis, a general term for inflammation of the vulva or vagina.

Healthcare-associated pneumonia management could be improved

Although healthcare-associated pneumonia is common among patients treated in internal medicine departments and linked to poor outcomes, rates of testing and adherence to therapeutic guidelines are low, say Spanish investigators.

Experts examine host recognition of Staphylococcus and E.coli bacteria

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often completely unnoticeable elimination of the invaders. Their immune-activating abilities were only detected in 1998, a discovery which was awarded with the Nobel Prize

Study explores role of L. reuteri against foodborne infection

While many bacteria exist as aggressive pathogens, causing diseases ranging from tuberculosis and cholera, to plague, diphtheria and toxic shock syndrome, others play a less malevolent role and some are critical for human health.

Researchers discover HVEM’s unknown role in fighting off E. coli infections

Despite ongoing public health efforts, E. coli outbreaks continue to infiltrate the food supply, annually causing significant sickness and death throughout the world. But the research community is gaining ground. In a major finding, published today in the scientific journal Nature, researchers from the La Jolla Institute for Allergy & Immunology have discovered a molecule's previously unknown role in fighting off E. coli and other bacterial infections, a discovery that could lead to new ways to protect people from these dangerous microorganisms.

Global warming may stimulate growth of cyanobacteria

Cyanobacteria are among the most primitive living beings, aged over 3,500 million years old. These aquatic microorganisms helped to oxygenate the earth-atmosphere. At present their populations are increasing in size without stopping. It appears that global warming may be behind the rise in their numbers and may also lead toan increase in the amount of toxins produced by some of these populations.
