This episode: New giant virus discovered, with a genome larger than that of some eukaryotes!
Some wild clones of social amoebas farm the bacteria they eat, but this is a losing strategy if nonfarming amoebas can steal the farmers’ crops. To make the strategy work, the farmers also carry bacteria that secrete chemicals that poison free riders. The work suggest farming is complex evolutio... Read More
This is simlpe phenotypic test which can be done in simple laboratory where molecular technology is not easily avaialble.phenotypic detection of MBL by 0.1mM EDTA.metallo-β-lactamase(MBL )is ambler's class B beta lactamase,which is inhibited by EDTA.this research work was done in our research l...

Metagenomics has been responsible for the discovery of various novel and clinically relevant human and environmental microorganisms. However, great care must be taken with the conclusions each group makes concerning whether a novel microorganism is associated with any given disease or phenotype... Read More
Lasers are the new DNA. It is called matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF) and it uses mass spectrometry to quickly test for hundreds of different pathogens in a small sample using a single automated device. MALDI-TOF is increasingly being used in clinical micr... Read More
Critically ill patients with the pandemic H1N1 influenza who received triple the standard dose of the influenza drug oseltamivir were 7 times more likely to completely clear the virus from their system in 5 days than those who received the standard dose. This discussion addresses the healthcare... Read More
Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis. Since the early 1980s, there has been an overall trend of an increase in reported pertussis cases. In this video participants discuss the resu... Read More
When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
There is much interest in the role of nutrients and micronutrients in the support of host defense against infections. However, there is controversy in the ability of supplements to help prevent or treat infections. Speakers discuss research on the role of vitamin D supplements to prevent and/or ... Read More
The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

Researchers at The Mount Sinai Medical Center have developed an innovative system to test how a virus interacts with cells in the body—to see, for example, what happens in lung cells when a deadly respiratory virus attacks them.
In the journal Cell Host & Microbe, investigators say such a tec... Read More
Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much as half of their body fluids in a single day.
Two groups of scientis... Read More
