A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University study.
Scientists discovered that IAFGP, an antifreeze protein in ticks that kicks in during winter, also fights infection. Synthesizing such a protein ma... Read More
Pseudomonas aeruginosa, Escherichia coli and Serratia marcescens were inoculated into gelatin agar using the stab method and incubated for 1 week at 37 degree’s C. If the organism has gelatinase then it can break down the gelatin (protein) into polypeptides and then amino acids which can then ... Read More
Plants have a symbiotic relationship with certain bacteria. These 'commensal' bacteria help the plants extract nutrients and defend against invaders -- an important step in preventing pathogens from contaminating fruits and vegetables. Now, scientists have discovered that plants may package thei... Read More
Ebola is transmitted from person to person through direct contact with the body or with body fluids of an infected person. Ebola virus is NOT a respiratory virus and is NOT transmitted through the air. It is not a gastrointestinal virus either, so it is NOT generally transmitted via water or foo... Read More
Federal officials today announced the first case of Ebola diagnosed in the U.S. The male patient was admitted to Texas Health Presbyterian Hospital Dallas and placed in strict isolation on September 28 after flying from Liberia to visit family in north Texas. The patient left Liberia on Septembe... Read More
The natural photo degradation of diazepam (valium) and similar medicines – followed by bacterial breakdown – may reduce their potentially harmful impact on the UK’s freshwater environment, a team of researchers has said.
Diazepam – used to treat anxiety and other similar conditions – has been... Read More
Humans are not the only primates ravaged by the deadly Ebola virus. Chimps and gorillas are also susceptible to the disease. The current Ebola epidemic, the biggest in human history, may have started with the butchering of an infected fruit bat. But it just as easily could have come from a chimp... Read More
Just in time for flu season, a new Michigan State University study of “the mother of all pandemics” could offer insight into infection control measures for the flu and other epidemic diseases.
Siddharth Chandra, director of MSU’s Asian Studies Center and professor in MSU’s James Madison Colle... Read More
An unknown airborne environmental isolate on Bile Esculin Agar (BEA) exhibiting a single circular colony. White hyphal growth with no spore formation. Clear to brownish exudate can be seen throughout the colony. This sample grew at refrigerated temperatures for several months. The agar surroun... Read More
I have received many questions about whether immunizing with Reston virus could protect against infection with Ebola virus. Usually the question comes together with the statement ‘because Reston virus does not cause disease in humans’. I can think of two reasons why a Reston virus vaccine is not... Read More
Viruses cannot multiply without cellular machinery. Although extensive research into how pathogens invade cells has been conducted for a number of viruses, we do not fully understand how the shell of a virus is cracked open during the onset of infection thus releasing the viral genome. An ETH Zu... Read More
Us government ban on research into enhanced pathogens also affects flu surveillance and vaccine work.
US researchers are worried that a temporary government ban on 'gain-of-function' experiments that boost the infectious properties of dangerous viruses may also cover less-extreme forms of the... Read More

A new study is helping to rewrite Ebola’s family history.
The research shows that filoviruses — a family to which Ebola and its similarly lethal relative, Marburg, belong — are at least 16-23 million years old.
Filoviruses likely existed in the Miocene Epoch, and at that time, the evolutio... Read More
The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research led by Yale researchers predicts.
The findings are published in the Oc... Read More
On July 20 a man who was ill flew on commercial planes from the heart of the Ebola epidemic in Liberia to Lagos, Nigeria's largest city. That man became Nigeria's first Ebola case—the index patient. In a matter of weeks some 19 people across two states were diagnosed with the disease (with one a... Read More
German an French Scientists found out: Soil bacteria contribute to the taste and smell of white truffles.
Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of tru... Read More
Over the past eight years, step-by-step, researchers have established a basic understanding of the CRISPR defenses against foreign DNA so widely used by both bacteria and archaea. We related the early story on STC in 2008 and commented on six additional questions in 2011. Still, questions remain... Read More
These days, antibiotics are no silver bullet. In fact, if you get them in the hospital, you may end up with an additional infection. Like the bug Clostridium difficile, or C. diff — which infects more than 300,000 Americans a year and kills some 14,000. C. diff flourishes in the post-antibiotic,... Read More
