Virus populations do not consist of a single member with a defined nucleic acid sequence, but are dynamic distributions of nonidentical but related members called a quasispecies (illustrated at left). While next-generation sequencing methods have the capability of describing a quasispecies, the ... Read More
An immune cell protein, ID2, is critical for the maintenance of healthy gut microbiota and helps these good bacteria fight off harmful bacteria, report scientists from the University of Chicago. The study, published in Immunity on April 21, suggests that novel therapeutics or microbiota transpla... Read More
One of the immune system's most critical challenges is to differentiate between itself and foreign invaders -- and the number of recognized autoimmune diseases, in which the body attacks itself, is on the rise. But humans are not the only organisms contending with "friendly fire." Read More
Vincent, Dickson, and Daniel review new insight into antigenic variation in trypanosomes, reveal the difficult solution to the last case study, and present another mystery for your solving.

This was indeed not easy to Google; one of my attempts even had a dr oz page as one of search results. Clearly a dead end. However with some persistence I came up with Entamoeba Histolytica.
The routine use of antibiotics in agricultural animals are headed in the wrong direction: sales of antimicrobials important for human medicine have increased 20 percent since 2009 and 3 percent since 2012. Read More
A new study published last week in the journal PLOS ONE explores the scope of malaria parasite diversity in southeast African birds, and provides insight into how lifestyle characteristics of birds can influence their association with different parasite genera. Read More
April 17, 2015 - A multicenter team of U.S. and Venezuelan scientists, led by researchers from NYU Langone Medical Center, have discovered the most diverse collection of bodily bacteria yet in humans among an isolated tribe of Yanomami Indians in the remote Amazonian jungles of southern Venezuel...

Research teams led by Edward Yu of Iowa State University and the Ames Laboratory have described the structures of two proteins they believe pump antibiotics from bacteria, allowing the bacteria to resist medications.
One of the protein pumps, known as MtrF, is believed to be the mechanism tha... Read More
The Centers for Disease Control and Prevention revised its guidelines on Ebola transmission on Sunday night, urging survivors to abstain from all forms of sex or use condoms every time “until more information becomes available,” rather than three months as previously recommended.
The World He... Read More

A concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics, according to laboratory experiments.
The findings, which will appear in the journal Applied and Environmental Microbiology, suggest that combining maple syrup extract with common antibiotics ... Read More
SAN DIEGO (April 14, 2015) -- A team of biologists from San Diego State University has developed a platform for identifying drugs that could prove to be effective against a variety of viral diseases. In a pair of recent articles in the Journal of Biomolecular Screening and the Journal of Visuali... Read More
Diseases such as HIV and Ebola are on the verge of being diagnosed almost instantly using paper-based technology costing less than $1. Read More
A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts ... Read More
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More
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...

Researchers at the University of Michigan are studying the ecology of microbes in the GI tract in hopes of developing novel diagnostic tests and effective treatments for intestinal disease. How are they studying this? By creating tiny gut ecosystems! Using undifferentiated stem cells, the inv... Read More
