The inhabitants of Earth are mostly microbes, and their activities are central to human welfare. Microbes can cause disease, but a properly functioning microbiome is essential for health. Microbes spoil food, but drive many forms of food production. Microbes mediate organismic decay, but catalyze numerous geochemical processes essential for life on Earth.

Research in the Penn Microbiology Department focuses on infectious agents that threaten global health, with an emphasis on understanding molecular mechanisms and developing key new methods. Areas of focus include pathogenic bacteria of the airway and gut, HIV/AIDS, insect- and rodent-borne viruses, herpes viruses, papillomaviruses, emerging infectious diseases and the human microbiome. On the host side, faculty study many areas of immunology related to infection, including innate and adaptive immunity, tumor immunology and vaccine development.

If I can wear a mask during my run, we can all wear them during the day. #MaskUpPHL

Love the initiative by ⁦@PHLPublicHealth⁩

Here, we report SARS-CoV-2 seroprevalence of >1,000 pregnant women in Philadelphia
9.7% Black and 10.4% Latina women seropositive
2.0% White and 0.9% Asian women seropositive
Racial/ethnicity differences in exposure likely driving differences in disease!

Study led by Scott Hensley @SCOTTeHENSLEY of @PennMicro shows that Black and Hispanic women are infected with coronavirus 5 times as often as white women #SARSCoV2 #COVID19 #coronavirus https://www.inquirer.com/health/coronavirus/coronavirus-covid19-black-hispanic-test-positive-vaccine-update-offit-20200709.html
