Visiting biosafety level-4 laboratories
Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the National Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunity to tour three BSL-4 laboratories in the United States and Australia. My […]

The value of influenza aerosol transmission experiments
A Harvard epidemiologist has been on a crusade to curtail aerosol transmission experiments on avian influenza H5N1 virus because he believes that they are too dangerous and of little value. Recently he has taken his arguments to the Op-Ed pages of the New York Times. While Dr. Lipsitch is certainly entitled to his opinion, his arguments […]

Implications of finding poliovirus in sewers of Brazil and Israel
Wild poliovirus has been detected in the sewers of Brazil and Israel. Fortunately, no cases of poliomyelitis have been reported in either country. Why is poliovirus present in these countries and what are the implications for the eradication effort? Wild type poliovirus (e.g. not vaccine-derived virus) was detected in sewage samples that had been collected […]

Reconstruction of 1918-like avian influenza virus stirs concern over gain of function experiments
The gain of function experiments in which avian influenza H5N1 virus was provided the ability to transmit by aerosol among ferrets were met with substantial outrage from both the press and even some scientists; scenarios of lethal viruses escaping from the laboratory and killing millions proliferated (see examples here and here). The recent publication of […]

Small Things Considered
A blog for sharing appreciation of the width and depth of microbes and microbial activities on this planet.
Microbial to Human Cell Ratio: Just Bragging Rights?
by Jeffrey L. Fox | Microbiota buffs repeat it often these days, proudly reminding the public that the microbial cells associated with humans outnumber their host cells by a ratio of ten-to-one. In his letter in the February 2014 Microbe, however, Judah L. Rosner of the National Institutes of Health (NIH) makes a strong case for…
When the Microbe Hits the Metal
by Leo Baumgart | Some heavy metals share a long history with microbes. Many of the metabolic processes that sustain life are believed to have originated from spontaneous reactions involving metals present in the early Earth. Our microbial ancestors figured out quickly how to use...
‘Tis the Season to be Sweating
by Elio | This is the time of the year of increased physical activity when we pay special attention to certain parts of the body, including the armpit. As is usually the case, our microbiota is involved because the odor associated with sweating is produced by microbial activity. The main culprits are skin…
Animating the Inanimate
by Marcelo Barros and Brana Vlasic | Concrete is the most widely used building material in the world, with untold amounts being produced yearly. It has always been regarded as a strong, solid, impenetrable, almost indestructible material yet it can make cracks that are vulnerable to penetration by water. As the result, structures of great economic and…
TWiM #82: Betrayal and Compromise
Vincent, Michael, Elio and Michele discuss how an endosymbiont betrays its aphid host to alert plant defenses, and a new immunosuppressive cell that allows infection of neonates.
To Retract or Not to Retract… That’s the Question
In the previous post I discussed  that editors of Science asked for the retraction of a paper linking XMRV retrovirus to ME/CFS. The decision of the editors was based on the failure of at least 10 other studies to confirm these findings and on growing support that the results were caused by contamination. When the authors refused […]

Science Asks to Retract the XMRV-CFS Paper, it Should Never Have Accepted in the First Place.
Wow! Breaking! As reported in WSJ earlier this week , editors of the journal Science asked Mikovits and her co-authors to voluntary retract their 2009 Science paper . In this paper Mikovits and colleagues of the Whittemore Peterson Institute (WPI) and the Cleveland Clinic, reported the presence of xenotropic murine leukemia virus–related virus (XMRV) in peripheral blood mononuclear cells […]

Does the NHI/FDA Paper Confirm XMRV in CFS? Well, Ditch the MR and Scratch the X… and… you’ve got MLV.
The long awaited paper that would ‘solve’ the controversies about the presence of Xenotropic Murine Leukemia Virus-related virus (XMRV) in patients with chronic fatigue syndrome (CFS) was finally published in PNAS last week . The study, a joint effort of the NIH and the FDA, was withheld, on request of the authors , because it contradicted […]
