It is well known that virus populations display phenomenal diversity. Virus populations are dynamic distributions of nonidentical but related members called a quasispecies. This diversity is restricted in single cells, but is restored within two infectious cycles. Read More
A study on the potential of SARS-virus-like bat coronaviruses to cause human disease has reawakened the debate on the risks and benefits of engineering viruses. Let’s go over the science and then see if any of the criticisms have merit. Read More
Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More

SAN DIEGO - People who end up in the emergency room because of a fall often are tripped up by an infection, rather than a loose throw rug or poor eyesight, suggests a study being presented at IDWeek 2015™. Read More
Influenza is known as an infectious respiratory disease, but a study published on October 8th in PLOS Pathogens suggests that infected cells in breast tissues could play a role in virus transmission from mothers to breast-feeding infants and vice versa using a ferret model. Read More
Investigators estimate that during 2012, there were more than 3.1 million emergency department visits for infectious diseases among elderly US adults. Read More
Tardigrades are small animals (~1.5 mm in length) renowned for their ability to survive in many extreme environments. From wikipedia "...they can withstand temperatures from just above absolute zero to well above the boiling point of water (100 °C), pressures about six times greater than those ... Read More
White-nose syndrome (WNS), an invasive skin infection caused by the Pseudogymnoascus destructans (Pd) fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene expression in hibernating bats infected with the destructive fungus published on October 1... Read More
In the 1960’s, the microbicide triclosan, was introduced in the United States, and soon after, human weight started to increase dramatically. For some time, researchers have wondered whether triclosan could have played a role in disrupting endocrine dysfunction and contributing to the obesity ep... Read More
Daniel and Vincent solve the case of the Truck Driver from India, discuss why parasites resistant to an antimalarial drug are not transmitted by mosquitoes, and introduce Paul who presents a new case study.

Leonilde M. Moreira, PhD, has been studying the Burkholderia complex for 15 years. The bacteria, known for causing pneumonia or septicemia in some individuals, can survive for prolonged periods in moist environments. During the last 10 years, it has become one of the more predominant bacteria se... Read More
Washington, DC – October 30, 2015 – Biofilms—mats of bacteria similar to the plaque that grows on teeth—frequently coat the surfaces of catheters, and of various medical implants and prostheses, where they can threaten lives or lead to failure of the implants. Antibiotics are impotent against b... Read More
