Early antibiotic exposure leads to lifelong metabolic disturbances in mice

Antibiotic exposure during a critical window of early development disrupts the bacterial landscape of the gut, home to trillions of diverse microbes, and permanently reprograms the body’s metabolism, setting up a predisposition to obesity, according to a new study. Moreover, the research shows t... Read More

Oddly Microbial: Selfish Genes*

Evolution is largely driven by conflict, not collaboration, according to cell evolutionist Harmit Malik at the Fred Hutchinson Cancer Research Center (FHCRC). Mammalian cells are contentious places, he explains, populated by alien and host genomic sequences fighting for dominance. "In the compet... Read More

Vaccines can cut the spread of meningitis by nearly 40 per cent

Investigators at the University of Southampton have discovered that two new vaccines can prevent the transmission of meningitis bacteria from person to person.

The vaccines do this by reducing ‘carriage’ of the responsible bacteria in the nose and throats of the population.

Meningitis is... Read More

Like cling wrap, new biomaterial can coat tricky burn wounds and block out infection

Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body’s most difficult-to-protect contours and ke... Read More

Wolbachia Genome Reduction, Phage WO, and Reproductive Parasitism

Abstract:

Wolbachia are maternally transmitted endosymbionts that often alter their arthropod hosts’ biology to favor the success of infected females, and they may also serve as a speciation microbe driving reproductive isolation. Two of these host manipulations include killing males outrigh... Read More

The Curious Case of a Protein and a Pilus

If you’re like me, every morning you reluctantly roll out of bed and automatically reach for your toothbrush. One of the earliest learned practices of personal hygiene, brushing surely serves more than just preventing daybreak halitosis — but have you ever pondered about the plaque you try to di...

It’s Funnier When You’re Right

The mystery of alcoholic fermentations was uncovered in the first half of the 19th century by Cagniard-Latour (1837) in France, and Schwann (1837) and Kützing (1837) in Germany, based on microscopic studies but not without controversy. The great German organic chemist Justus Liebig did not like ... Read More

Dandruff-Causing Skin Fungi Discovered Unexpectedly in Deep Sea Vents, Antarctica

Until relatively recently, the fungus Malassezia was thought to have one favorite home: us. As the dominant fungus on human skin and sometimes-cause of dandruff, the yeast Malassezia was thought to live a simple if sometimes irritating domestic existence humbly mooching off the oils we exude.

The typhoid fever pathogen uses a cloaking mechanism to evade neutrophil neutralization

Typhoid fever is caused by systemic infection with Salmonella enterica Typhi. In contrast, infection with the closely related bacterium Salmonella enterica Thyphimurium is usually limited to the gut and causes less serious diarrheal disease. Research comparing the two pathogens reveals how S. Ty... Read More

Ebola Doctor Reveals How Infected Americans Were Cured

Last week two American aid workers who had contracted Ebola while working in west Africa were released from a U.S. hospital and pronounced “recovered.” They had been flown to Emory University Hospital in Atlanta from Liberia earlier this month to receive care in the hospital’s specialized infect...

Taxis, Planes and Viruses: How Deadly Ebola Can Spread

For scientists tracking the deadly Ebola virus in West Africa, it is not about complex virology and genotyping, but about how contagious microbes - like humans - use planes, bikes and taxis to spread.

So far, authorities have taken no action to limit international travel in the region. The ai... Read More

Fluoribacter bozemanae expressing blue-white fluorescence under long-wave UV light. If you look carefully one of the steaks does not fluoresce on the right hand side of the plate. The dark colony is actually Legionella pneumophila. Read More

Source: Flight en route to Liberia to evacuate Americans infected with Ebola

According to CNN,a long-range business jet with an isolation pod left the United States for Liberia, where it will evacuate two Americans infected with Ebola.

Twitter exploded with questions about the deadly virus, which according to the World Health Organization is believed to have killed hu... Read More

Gut bacteria that protect against food allergies identified

Common gut bacteria prevent sensitization to allergens in a mouse model for peanut allergy, paving the way for probiotic therapies to treat food allergies.

The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. By inducing immun... Read More

Ebola Could Eventually Afflict Over 20,000, W.H.O. Says

As the tally of deaths from the worst known outbreak of the Ebola virus continued its seemingly inexorable rise, the World Health Organization said on Thursday that the epidemic was still accelerating and could afflict more than 20,000 people — almost seven times the current number of reported c...

Zaire ebolavirus in West Africa

Dr. Tom Solomon is Director of the Institute for Infection and Global Health at the University of Liverpool. In this video he speaks with Vincent Racaniello about the 2014 outbreak of Zaire ebolavirus in West Africa. Dr. Solomon discusses why the epidemic has spread, how it might be curtailed, t...

Malaria’s Clinical Symptoms Fade on Repeat Infections Due to Loss of Immune Cells

Children who repeatedly become infected with malaria often experience no clinical symptoms with these subsequent infections, and a team led by UC San Francisco researchers has discovered that this might be due at least in part to a depletion of specific types of immune cells.

Working in Ugand... Read More

‘Wormy’ Pills Might Fend Off Autoimmune Diseases

Scientists have identified peptides from parasitic hookworms that can calm the body’s immune response and perhaps pave the way to treat autoimmune diseases.

Experts believe the peptide molecules could help explain why worm infections can effectively treat diseases such as multiple sclerosis, ... Read More
