How bacteria with a sweet tooth may keep us healthy

Some gut bacterial strains are specifically adapted to use sugars in our gut lining to aid colonisation, potentially giving them a major influence over our gut health.

We live in a symbiotic relationship with trillions of bacteria in our gut. They help us digest food, prime our immune system ... Read More

Herpes infected humans before they were human

Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...

Deadly MERS Virus Circulates Among Arabian Camels

Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.

It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study p... Read More

Mollusk parasite culturing methods drive research

Researchers at Bigelow Laboratory for Ocean Sciences dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, more papers and greater understanding result. Senior Research S... Read More

Researchers find chemicals that treat citrus greening in the lab

A University of Florida research team is cautiously optimistic after finding a possible treatment in the lab for citrus greening, a disease devastating Florida’s $9 billion citrus industry. It is the first step in a years-long process to bring a treatment to market.

Unknown Floor isolate #2

Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and mounding in an irregular-rhizoid form with lobate margins. The colony exhibited an opaque yellow-orange pigment with a mucoid surface. This sample was obtained from a floor swab and incubated at 37°C. Read More

The pathogen detectives: sourcing the post-earthquake cholera outbreak in Haiti

Natural disasters such as earthquakes can have far-reaching effects beyond the damage caused on the day they occur. The 2010 earthquake in Haiti damaged the already limited sanitation systems leading to areas without adequate toilet and washing facilities; perfect for the spread of infection dis... Read More

New Wearable Device Could Protect Against HIV and Pregnancy

If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.

Scientists explore the mechanisms of viruses' shells

The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell. The scientists of the International School for Advanced Stu... Read More

Facilitation of horizontal transfer of antimicrobial resistance by transformation of antibiotic-induced cell-wall-deficient bacteria

It is universally accepted that the use of antibiotics will lead to antimicrobial resistance. Traditionally, the explanation to this phenomenon was random mutation and horizontal gene transfer and amplification by selective pressure. Subsequently, a second mechanism of antibiotic-induced antimic... Read More

New device will find carcinogenic food fungus faster

One of the food industry’s major recurring challenges, detecting highly carcinogenic toxins that occur naturally in our most common crops, could soon be solved by groundbreaking research that exploits aflatoxins’ fluorescent properties.

Detecting Aflatoxins

Aflatoxins are present in a wide... Read More

Researchers find that going with the flow makes bacteria stick

In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections t... Read More

Ultra-violet Light Works as Screening Tool for Bats with White-nose Syndrome

Scientists working to understand the devastating bat disease known as white-nose syndrome (WNS) now have a new, non-lethal tool to identify bats with WNS lesions —ultraviolet, or UV, light.

If long-wave UV light is directed at the wings of bats with white-nose syndrome, it produces a distinct... Read More

Metallo-β-lactamase producing Acinetobacter species

Acinetobacter species are among the most common nosocomial pathogens that are notorious for multi-drug resistance. Their immense ability to acquire or upregulate antibiotic drug resistance determinants has established them as a successful pathogen, causing wide range of infections such as wound ... Read More

Pathogens in Cheese – Researchers Follow the Traces of Deadly Bacteria

If food products are not produced in a hygienic environment, consumers can face the threat of dangerous pathogens. This is exactly what happened in 2009 and 2010 when two different strains of Listeria monocytogenes were found in the traditional Austrian curd cheese known as “Quargel”. 34 people ... Read More

Adhering To The 'Replicon Model' The Sloppy Way

Sixty years ago Jacob, Brenner and Cuzin devised their 'Replicon Model', inspiring and useful guideline for replication research ever since. According to the model, a 'Replicon' is a genetic element replicated from a single 'Replicator'—replication origin, in modern terms—and replication is trig... Read More

Think We're Rid of Measles? Think Again

Over the last few weeks, the numerous outbreaks of measles in Canada have led many public health officials and microbiologists to shake their collective heads. The reason is simple: this should not be happening. Of all the pathogenic viruses, this one has been on our radar for nearly 200 years a... Read More

Virus kills triple negative breast cancer cells, tumor cells in mice

A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer.

Adeno-associated virus... Read More
