A Tale of Two Strategies

Bacteria are for the most part gregarious organisms, living predominantly in dense communities consisting of multiple strains. In fact, the majority of infectious bacteria occur as multi-layered structures called biofilms, many of which are composed of multiple types of bacteria. As one can imag... Read More

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

Amyotrophic lateral sclerosis and viruses and my ice bucket challenge

Many people have a new awareness of the disease known as amyotrophic lateral sclerosis, or ALS, thanks to the Ice Bucket Challenge initiated by the ALS Association. Fewer might know that retroviruses have been proposed to play a role in the development of the disease. 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

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

Breakthrough antibacterial approach could resolve serious skin infections

Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria ac... 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

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

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

Hot-spring bacteria reveal ability to use far-red light for photosynthesis

This video contains images of LaDuke hot spring in Gardiner, Montana, along the Yellowstone River, near Yellowstone National Park. The images show the rich mat community of chlorophototrophic bacteria that grow along the hot spring's effluent channel. The dark-green-colored organisms are mainly ... Read More

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

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

Which is the morphology of this micro-organism?

Please help me! I am planning to identify this microorganism by API but I can not identify the shape (rod or cocci). This microorganism has positive oxidase. Its colony is red, irregular, flat.
Please teach me. Thanks so much! Nhu Thuy from Vietnam

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.

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

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...
