Cytomegalovirus hijacks human enzyme for replication

Researchers at Princeton have discovered that cytomegalovirus manipulates a process called fatty acid elongation, which makes the very-long-chain fatty acids necessary for virus replication. Published in the journal Cell Reports on March 3, the research team identified a specific human enzyme--e... Read More

HIV can spread early, evolve in patients' brains

The AIDS virus can genetically evolve and independently replicate in patients' brains early in the illness process, researchers funded by the National Institutes of Health have discovered. An analysis of cerebral spinal fluid (CSF), a window into brain chemical activity, revealed that for a subs... Read More

Uehling ASM Global Video Challenge: Is it worthwhile to study non-pathogenic environmental microbes?

This is my submission for the global video challenge. I study fungal bacterial interactions, and Im currently using microbes isolated from soil around plant roots. The aim of the larger supporting research framework is to understand the structure and function of beneficial microbial communities ... Read More

Computational model simulates bacterial behavior

University of Notre Dame applied mathematician Mark Alber and environmental biotechnologist Robert Nerenberg have developed a new computational model that effectively simulates the mechanical behavior of biofilms. Their model may lead to new strategies for studying a range of issues from blood c... Read More

Unknown Fungus with spores different view

Different view of TSA plate with fungal contaminant, presumably from the air, after 1 month at refrigerated temperatures. White center spore formation can be seen with white hypae on the edges. Spore formation can be see forming towards the edges. Read More

Toxic Bacteria Detection - Bang Goes The Theory (video)

Dr Toby Jenkins talks about toxic bacteria and how to detect that using a technology within bandages. Taken from Bang Goes The Theory Series 7. Read More

YOUR GUT NEEDS BACTERIA TO MAKE MORE SEROTONIN

A new study from CalTech suggests that serotonin levels may be regulated to some degree by the gut microbiome. Researchers are investigating the degree to which bacteria in the guts of mice are able to confer serotonin-dependent function in comparison to control, or "germ-free" mice. Further s... Read More

Meet The Bacteria That Make A Stink In Your Pits - NPR

Scientists measured how much thioalcohol -- a molecule that makes your underarms smelly -- each species of bacteria produced, and found Staphylococcus hominis was one of the worst offenders. They are hoping that the findings will change the way that we fight body odor, and envision a deodorant t... Read More

IS ‘TASTIER’ RAW MILK WORTH THE RISK?

A recent study shows that consumption of unpasteurized milk significantly increases the risk of food-borne illness, which can be severe or even fatal in some cases. The scientific consensus points to a lack of knowledge of the 'benefits' of consuming raw milk, and an abundance of peer-reviewed... Read More

E. coli design on MacConkey

These are two harmless lab strains of E. coli. One can ferment the sugar lactose into acidic byproducts and the other cannot. MacConkey media contains an indicator dye that turns from red to yellow when the pH is raised. The four pink streaks were drawn with a culture of the lactose fermenter (t... Read More

Anti-HIV antibody shows promise in first human study

A single infusion of an experimental anti-HIV antibody called 3BNC117 resulted in significantly decreased HIV levels that persisted for as long as 28 days in HIV-infected individuals, according to Phase 1 clinical trial findings published online today in Nature. Read More

HOW ZINC ‘JAMS UP’ THESE DRUG-RESISTANT MICROBES

New research from the University of Queensland has shown how zinc "tricks" an essentialmManganese-transport protein of S. pneumoniae into a shape in which it can't accept manganese. It is known that manganese is essential for S. pneumoniae infection to occur, so this research offers a chance to... Read More

Gene variant and environment can boost severity of respiratory syncytial virus

A study published in the Journal of Clinical Investigation suggests that environmental factors, in conjunction with a mutation of the TLR4 gene, may contribute to the severity of RSV-related respiratory illness in children. TLR4 is a gene involved in the innate immune response, and investigator... Read More

Pictures Considered #25. Getting A Ride

From Moselio Shaechter of ASM's Small Things Considered:

"A recent review article deals with the fascinating phenomenon of pathogens exiting from their host cell. Sometimes, one pathogen helps another one in transmission to the next host. In one case, a Candida albicans hypha caught in the ac... Read More

Microorganism not yet cultivatable or difficult to cultivate in the laboratory

My global video challenge is about microorganism not yet cultivatable or difficult to cultivate in the laboratory. With new microorganism cultivation techniques is possible the discovery of new microorganisms. Read More

A protein platform for priming

The enzymes that make copies of the DNA or RNA genomes of viruses – nucleic acid polymerases – can be placed into two broad categories depending on whether or not they require a primer, a short piece of DNA or RNA, to get going. The structure of the primer-independent RNA polymerase of hepatitis... Read More

Six questions about HIV/AIDS that deserve more attention

As HIV investigators work to control and eradicate the virus worldwide, certain myths or misconceptions about the disease have been embraced, whereas other concepts with merit have been left relatively unexplored, argues American HIV/AIDS researcher Jay Levy, MD, in a commentary publishing April...
