Phage spread antibiotic resistance

Investigators found that nearly half of the 50 chicken meat samples purchased from supermarkets, street markets, and butchers in Austria contained viruses that are capable of transferring antibiotic resistance genes from one bacterium to another—or from one species to another. "Our work suggests... Read More

Antibody's unusual abilities might inspire vaccine strategies

The recent discovery of a novel antibody that works in an unusual way might inspire ideas for designing more effective vaccines. Among the common pathogens that could be targeted are urinary-tract infecting strains of E. coli. Read More

New age of genome editing could lead to cure for sickle cell anemia

UNSW Australia researchers have shown that changing just a single letter of the DNA of human red blood cells in the laboratory increases their production of oxygen-carrying haemoglobin - a world-first advance that could lead to a cure for sickle cell anaemia and other blood disorders. Read More

UGA research finds geckos resistant to antibiotics, may pose risk to pet owners

Tokay geckos harbor bacteria that are resistant to a number of antibiotics, making them a health concern for pet owners, according to a study by University of Georgia researchers.

Tokay geckos, a type of gecko known for the "to-kay" sound it makes, are caught in the wild and often imported in... Read More

Bacteria May Be Remaking Drugs in Sewage

Wastewater treatment plants not only struggle removing pharmaceuticals, it seems some drugs actually increase after treatment.

When researchers tested wastewater before and after treatment at a Milwaukee-area treatment plant, they found that two drugs—the anti-epileptic carbamazepine and anti... Read More

Bacteria contribute to immune suppression in skin after repeated schistosome exposure

Our two square meters of skin act as a defensive barrier against environmental pathogens but is also covered by beneficial commensal bacteria. We live alongside these bacteria without excessive and unnecessary immune responses, which could destroy the skin's function as a barrier and so make us ... Read More

U.S. report shows mixed progress on curbing foodborne pathogens

U.S. cases of two deadly types of foodborne pathogens have fallen sharply since 2008, but rates of other key types of foodborne bugs have increased, according to the latest report on nine pathogens tracked by health officials.

"The picture is mixed," said Dr. Patricia Griffin of the U.S. Cent... Read More

New study eases fears of airborne Ebola

At the peak of the Ebola epidemic last fall came a frightening new possibility: a mutation that could allow the disease to spread through the air. Now University of Florida researchers have dispelled this concern using data from current and past Ebola outbreaks.

While concern about airborne E... Read More

Unknown environmental contaminant on blood agar plate streaked with Enterococcus faecalis

Unknown environmental contaminant on blood agar plate streaked with Enterococcus faecalis. Plated was incubated at 37 degrees C for 24 hrs then held at room temperature. Contaminant was not seen until plate was held at room temp for several weeks. The organism was red, mucoid, and had raised... Read More

Unknown Yeast Contaminant

Unknown Yeast contaminant seen on Casein media. The contaminant was around the edges of the plate with isolated colonies seen towards the center of the plate after 1 month refrigerated temperatures. Colonies were light opaque pink, mucoid and had concentric rings slightly elevated in the cen... Read More

The fifty shades of antibiotic resistance

Professor Dr. Luca Guardabassi gave the talk at Science and cocktail events on April 2015.
How many people die because of antibiotic resistance every year? Which people have a higher risk to die of bacterial infections? Is consumption of antibiotics in Danish livestock higher than in other cou... Read More

Bacterial melanin can replace Non-steroidal anti-inflammatory drugs (NSAIDs) in arthritis treatments

Melanin produced by a marine bacteria Bacillus spp. has shown shown to have good anti-inflammatory activity. The pigment had shown to inhibit inflammatory enzymes cycloxygenase, lipooxygenase, myeloperoxide,NO synthase in vitro at a concentration which was non-cytotoxic..This will be a breakthro...

Molecular homing beacon redirects human antibodies to fight pathogenic bacteria

With the threat of multidrug-resistant bacterial pathogens growing, new ideas to treat infections are sorely needed. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report preliminary success testing an entirely nove... Read More

Are we exposed to antibiotic resistance in coastal waters? (video)

PhD student Anne Leonard talks through her latest research paper, which shows that people who take part in coastal water sports could be at risk of exposure to antibiotic resistant bacteria.

Discovery of the Sixth DNA base?

Scientist has described the possible existence of sixth DNA base, the methyl-adenine (mA) this week.

Deoxyribonucleic acid (DNA) is a polymer of nucleotides, which encodes every genetic information of living existence. The entire genetic information are stored within DNA as the form of millio... Read More

Designer viruses for killing tumor cells

A major goal of viral oncotherapy – the use of viruses to destroy tumors – is to design viruses that kill tumor cells but not normal cells. Two adenoviruses provide perfect examples of how this specificity can be achieved.

Adenovirus CG0070, designed to treat bladder cancer, and adenovirus O... Read More

Freshman Biology Creative Projects

I am a big believer that different pedagogical approaches can "reach" different students. In most of my classes, I give students an optional assignment: come up with a creative project that explores some aspect of class. This takes several steps. First, I make the students come up with an ide... Read More
