Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

In order to feed the growing global population that is expected to reach 9 billion by 2050, agricultural yields will need to increase by 70-100%. However, increasing this yield using current methods is not a viable option. Not only is it environmentally damaging, it is also not economically feas... Read More
The 1918 influenza pandemic was particularly lethal, not only for the very young and the very old (as observed for typical influenza), but unexpectedly also for young adults, 20 to 40 years of age (pictured). It has been suggested that the increased lethality in young adults occurred because the... Read More
Team of researchers guided by Dr.Sarita G Bhat had developed a novel plate based screening technique for DOPA/melanin producing bacteria.Screening was based upon the clear zone formation on a medium suplemented with L-tyrosine.This new approach can be utilized in faster and accurate screening of...

In this blog post, I show how students in my freshman "introduction to cell and molecular biology" course used "creativity"-based approaches to better understand concepts in the course---as they prepare for their upcoming final exam. I believe that this kind of approach truly helps with student... Read More
It causes human mucormycosis and bovine mycotic abortion.
It is distinguished from R.arrhizus by its shorter stalk, and smaller sporangia and spores.
Var.oligosporus : has elongated columellae ; spores less obviously striated.
Var.rhizopodiformis : has ... Read More
An interesting recent paper characterizing the fungal microbiome ("mycobiome") of human skin. It would be lovely if the TWIM crew could discuss this in an upcoming episode!
"Traditional culture-based methods have incompletely defined the microbial landscape of common recalcitrant human fungal... Read More
In this blog entry, I discuss a talk I attended at ASMCUE about "Citizen Science" and how some of my own work appeared in that talk! It is a vital that we scientists explain not just what we do, but why it is so fascinating to us...by involving the public! Read More
The TWiVers review the outcomes of two recent phase 3 clinical trials of a quadrivalent dengue virus vaccine in Asia and Latin America.
In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.
You can find my virology lect... Read More
Given the extent of the Ebola virus outbreak in West Africa, transport of an infected individual to the US was bound to happen. The case is an adult who had contact with an Ebola virus-infected woman in Liberia, then traveled to Dallas. He had no symptoms before arriving in the US and therefore ... Read More
Until we have "action figures" of scientists, I do what I can to recognize scientists that have had a large and lasting influence on my academic career. In this blog post, I praise Dr. Moselio Schaechter for his clear and insightful approaches to microbiology. His enthusiasm, breadth of interes... Read More

The workshop will have the following modules:
• 'Phylogene... Read More
This week’s virology question comes from Eric, who writes:
I’m working on an MPH and in one of my classes we are currently studying the influenza virus. I’d forgotten that the genome is in 8 separate parts. Curious, I’ve been searching but can’t find any information as to why that is?
What... Read More
The coronavirus responsible for Middle East Respiratory Syndrome (MERS) is prevalent in camels throughout Saudi Arabia and has been around for at least 20 years, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology.
“Our study ... Read More
An outbreak of hepatitis A virus (HAV) infections in eight US states has been attributed to consumption of Townsend Farms Organic Anti-Oxidant Blend frozen berry and pomegranate mix purchased from Costco markets. Since March 2013, 118 individuals have acquired the infection and 80% report having... Read More
Emergence and dissemination of antibiotic resistance plasmids are major concern for hospital care system and
increases the cost and decreases effectiveness of available antibiotics used in treatment of hospitalized patients.
In this study two Pseudomonas aeruginosa, two Escherichia coli, and a... Read More
Scientists have developed a strain of the Middle East respiratory syndrome coronavirus (MERS-CoV) that could be used as a vaccine against the disease, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology. The mutant MERS virus, rM... Read More
My wife, who is a mathematician and artist, made a stop motion video using Play-Doh that represents the life cycle of the bacterial predator, Bdellovibrio. This brings together interesting microbes, animation, and thoughts about what students might do to understand processes in microbiology! Read More
DNA microarrays are widely used in biological research and were once thought to be a very promising gene discovery tool. However, since the advent of next generation DNA sequencing, the popularity of DNA microarrays has steadily declined. Compared to the sequencing, microarray behavior is unce... Read More
