"The Amazing Adventures of the Virologists” Part One - Vaccines _ 6

"Hivi and his team of viruses (Ebola, Pox,..etc) believe they can win the battle, but the Virologists (who are real famous professors) beat them. However, new viruses pop-up, it will be a long battle. This makes the story very interesting and ever so engaging."

Zika Sharing

Of all the scientific results that my laboratory has produced over the years, I am most satisfied by those that maximally benefit the field. In this category falls the assay for determining the titer of Zika virus in plaque forming units per milliliter.

In ‘Counting Zika Virus’ I described o... Read More

Microbial Genomics and the Future of Food Microbiology

There’s no question that foodborne disease is a serious problem. Illnesses from contaminated foods cause over 128,000 hospitalizations and 3,000 deaths each year in the United States. The Centers for Disease Control and Prevention estimates that one in six Americans suffers a food-related illne... Read More

Yum! Digesting ASM Resources for Food Microbiology

Food-related microbiology can be one of the most fun - or least fun - ways to interact with microbes. In the ‘most fun’ category, scientists and non-scientists alike can use microbes to create delicious foods from fermentative processes; in the ‘least fun’ category, scientists and non-scientists...
