Scientists wonder why some people get so sick and even die after being infected by the foodborne pathogen E.coli O157:H7, while others experience much milder symptoms and recover relatively quickly. Now Penn State's College of Agricultural Sciences researchers believe they have discovered an exp... Read More
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More

Pseudomonas aeruginosa is one of the most notorious organisms that have brought the therapeutic dilemmas to clinicians as well as challenge to microbiologist throughout the world. It carries gene of intrinsic resistance (AmpC cephalosporinase, the OprD outer membrane porin, and the multidrug ef... Read More
DETROIT - The number of hepatitis C patients suffering from advanced liver damage may be grossly underestimated and underdiagnosed, according to a study led by researchers at Henry Ford Health System and the U.S. Centers for Disease Control and Prevention. Read More
HIV-infected patients remain on antiretroviral therapy for life because the virus survives over the long-term in infected dormant cells. Interruption of current types of antiretroviral therapy results in a rebound of the virus and clinical progression to AIDS. Read More
West Nile virus (WNV) is particularly dangerous in older people, who account for a large number of severe cases and deaths caused by the virus. WNV infection turns serious when the virus crosses the blood-brain-barrier and wreaks havoc among nerve cells in the brain. A study published on July 23... Read More
As my Fall semester approaches, I am reflecting on last Fall. I taught a freshman seminar course revolving around symbioses and parasitism, and was fortunate to have many well known scientists be willing to "virtually visit" my class! Here is my report from last year on the great Jack Gilbert.... Read More
Colorized transmission electron micrograph of Avian influenza A H5N1 viruses (seen in gold) grown in MDCK cells (seen in green).
Avian influenza A viruses do not usually infect humans; however, several instances of human infections and outbreaks have been reported since 1997. When such infecti... Read More
This thin section transmission electron micrograph (TEM) depicts numerous virions revealed in a preparation of HIV (human immunodeficiency virus).
HIV is the virus that can lead to acquired immune deficiency syndrome, or AIDS. CDC estimates that about 56,000 people in the United States contract... Read More
