At the same time, milder weather is allowing ticks to spread into new geographic regions. Findings were published ... Read More

Breastfeeding, Other Factors Help Shape Immune System Early in Life

Henry Ford Hospital researchers say that breastfeeding and other factors influence a baby’s immune system development and susceptibility to allergies and asthma by what’s in their gut.

The striking findings from a series of studies further advance the so-called hygiene hypothesis theory that ... Read More

Fungal close up

Close up image of the edge of an unknown fungal contaminant showing concentric rings of black spore formation (center of colony) and nonspore forming white hypae on the outer edge of the colony. Fungal contaminant was found on TSA after a month of refrigerated temperatures, presumably an air bo... Read More

Virus-cutting enzyme helps bacteria remember a threat

Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro...

World Health Organization approves 15-minute Ebola detection test

Until now, the standard way to check for Ebola in the region was to use the nucleic acid test, which works by identifying the genetic materials of the virus from a blood sample. Yet the test requires a full lab to succeed, and it takes between 12 to 24 hours to process the results. In comparison... Read More

Global Warming May Spawn New Disease Outbreaks

Infections lurking on the margins of civilization are becoming more likely to cause outbreaks as the climate changes, researchers say. Ravens, rodents and rattlesnakes are moving to new locales as rainfall and temperatures shift over time (ClimateWire, Dec. 14, 2011).

2012 Salmonella Illness Linked to Microbiology Class

On May 30, 2012 Brianna Dannen, Public Health Nurse at the Clark County Health District (CCHD), received a call from Bob Williamson at Clark College. Mr. Williamson called to report that a child of a Clark College student enrolled in a microbiology class, BIOL&260, taught by Travis Kibota was i... Read More

HIV strain matters for treating new cases

The specific strain of HIV that a person first contracts can have a lasting impact on how the virus disrupts his or her immune system, say researchers.

“This may have important implications for cure strategies aimed at eliminating the viral reservoir, as individuals infected with low replicat... Read More

First results from Ebola vaccine trial show acceptable safety profile

The first results from a trial of a candidate Ebola vaccine at Oxford University suggest the vaccine has an acceptable safety profile at the doses tested, and is able to generate an immune response.

'The vaccine was well tolerated. Its safety profile is pretty much as we had hoped,' said Prof... Read More

Airport screening misses half of disease cases but could be improved

Scientists have shown that airport screening for disease will often miss half or more of infected travelers, but can be improved by customizing to pathogens. The findings are published in the journal eLife.

They present options for policy makers; for example whether resources would be better ... Read More

Superbug outbreak has killed two at UCLA medical center

This week, doctors at the University of California Los Angeles Medical Center discovered that a contaminated medical tool had been spreading antibiotic-resistant bacteria to patients. The bacteria, known as carbapenem-resistant Enterobacteriaceae or CRE, has been called a “nightmare” bacteria by... Read More

CU neurologist finds link between virus causing chicken pox and giant cell arteritis

A new study developed at the University of Colorado School of Medicine at the Anschutz Medical Campus links the virus that causes chicken pox and shingles to a condition that inflames blood vessels on the temples and scalp in the elderly, called giant cell arteritis.

Paenibacillus glucanolyticus spore

Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti... Read More

Ancient rocks show life could have flourished on Earth 3.2 billion years ago

The ability to use atmospheric nitrogen to support more widespread life was thought to have appeared roughly 2 billion years ago. Now research from the University of Washington looking at some of the planet’s oldest rocks finds evidence that 3.2 billion years ago, life was already pulling nitrog... Read More

Mutant bacteria that keep on growing

The typical Escherichia coli, the laboratory rat of microbiology, is a tiny 1-2 thousandths of a millimeter long. Now, by blocking cell division, two researchers at Concordia University in Montreal have grown E. coli that stretch three quarters of a millimeter. That's up to 750 times their norma... Read More
