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.

We had a lot of fun today in Science at the Park @clarkpark teaching families about the @microbiome and different #bacterias shapes. @PhilaSciFest looking fwd to the #ScienceCarnival #GetNerdyPHL #STEM


Congratulations to two of our 2nd year MVP students, whose NSF fellowship applications received honorable mentions: @theMANzoni01 from the @CBLPHL Lab and Nathan Krump from Jianxin You’s Lab! @CAMBUpenn https://t.co/Pin7t3UNSr

Great Thesis defense by @sbart143...and amazing support of @PennMicro and MVP grad program peers...! Congrats Dr. BART!

Check out the new paper from @BushmanLab on the gut microbiota from bilaterially symmetric animals, surveying creatures from flies to whales. For colonization, selection beats stochastics! https://t.co/YddqkhlUaU
