Criss Lab News

March 2014

Kylene was awarded a stipend from the Hutcheson Fund to support her Summer 2014 research in the Criss lab on mechanisms of gonococcal internalization by human neutrophils. Congratulations, Kylene!

March 2014

Brittany was selected for an oral presentation at the 2014 Huskey Research Exhibition and received second place for her talk! A link to UVA Grad Days and the Huskey Research Exhibition can be found here.



Huge congratulations to Brittany, who was selected as the winner of the 2014 Robert R. Wagner Prize for Outstanding Research in Microbiology! Brittany received the Wagner Award and presented a seminar to the Department and School of Medicine on March 19, 2014.

January 2014

Congratulations to Asya and Kylene, whose manuscript “Assembly of NADPH oxidase in human neutrophils is modulated by the opacity-associated protein expression state of Neisseria gonorrhoeae” was accepted for publication in Infection and Immunity. This work shows that infection of neutrophils with opacity protein-negative gonococci prevents the proper assembly of the holoenzyme that generates reactive oxygen species,  to block the neutrophil oxidative burst.  The manuscript can be accessed here.


November 2013

Alison and colleague Ian Glomski co-hosted the Virginia Branch of the American Society for Microbiology annual meeting at UVA on November 8 and 9. The Criss lab was well represented: Jonathan and Rick were selected to give talks, and Stephanie, Louise, Brittany, and Kylene presented posters! Kylene and Brittany received travel awards for their presentations.



October 2013

Brittany was selected to present a poster at the NIH National Graduate Student Research Conference. It was unfortunately canceled due to the government shutdown.



October 2013

Congratulations to the UVA International Genetically Engineered Machine (iGEM) team, which won a gold medal at the North America semifinal and competed in the Global iGEM Championship! Alison advised the team on engineering E. coli minicells that would last longer in the human body without provoking inflammation. Check out Team Virginia's website, the UVA Today article, and a YouTube video where Alison was interviewed about synthetic biology and the promise of minicells.



September 2013

Alison received the UVA School of Medicine’s Dean’s Award for Excellence in Research! Click here for the award poster.


September 2013

The Journal of Visualized Experiments published Brittany and Alison’s video article, “Fluorescence microscopy methods for determining the viability of bacteria in association with mammalian cells.” The video and a PDF of the protocol can be accessed here.


July 2013

Alison and former undergraduate Erin Dale contributed to “Neisseria gonorrhoeae metalloprotease NGO1686 is required for full piliation, and piliation is required for resistance to H2O2- and neutrophil-mediated killing,” which was published in the July/August 2013 issue of mBio. The article can be found here.


July 2013: Brittany Johnson was selected to participate in the 2013 American Society for Microbiology’s Kadner Institute. The Kadner Institute provides guidance on preparation for careers in microbiology.  More information is available here:


June 2013: Alison was invited to speak at the 2013 Phagocytes Gordon Research Conference. Her talk was entitled "Survival of Neisseria gonorrhoeae after primary human neutrophil challenge.”  More information on this conference is available here:

asmconference2013logosm.jpg May 2013: Alison gave the talk "Playing with fire: Neutrophils in the pathogenesis of Neisseria gonorrhoeae" at the 113th General Meeting of the American Society for Microbiology in Denver, Colorado.
opacolonycriss140.jpg April 2013:

The manuscript “Constitutively Opa-expressing and Opa-deficient Neisseria gonorrhoeae differentially stimulate and survive exposure to human neutrophils,” by Louise and Alison, was accepted at the Journal of Bacteriology. It was published in the July 1, 2013 issue and can be accessed here.


March 2013: Brittany Johnson and Kylene Daily were selected to present at the "Two Hoos" session of the Huskey Graduate Research Exhibition on March 27, 2013.  Their talk on "Mechanism of Neisseria gonorrhoeae internalization by neutrophils" was one of seven given by pairs of graduate and undergraduate student researchers.  Congratulations Brittany and Kylene!


February 2013: Congratulations to Kylene Daily, who received a 2013 Harrison Distinguished Undergraduate Research Award!  Kylene's project will explore how unopsonized Neisseria gonorrhoeae is internalized by primary human neutrophils.  More on the Harrison Awards is available here (


January 2013: We welcome Stephanie Ragland to the Criss lab!

Stephanie received her undergraduate degree from Virginia Commonweath University and worked in Jason Carlyon's lab at VCU prior to entering the BIMS program at UVA in July 2012.


January 2013:

The manuscript “Neisseria gonorrhoeae phagosomes delay fusion with primary granules to enhance bacterial survival inside human neutrophils,” by Brittany and Alison, was accepted at Cellular Microbiology [remove link to journal] and was published in the August 2013 issue. Brittany’s image was selected for the cover! The manuscript can be found here.

January 2013:

The Criss lab presented at the Mid-Atlantic Microbial Pathogenesis Meeting at Wintergreen Resort in Virginia, January 27-29.  Brittany Johnson was selected to give a talk and received a travel award.  Louise Ball, Jonathan Handing, Rick Juneau, and Asya Smirnov presented posters.

2012: Congratulations to Jonathan Handing and Rick Juneau for appointment to the UVA Infectious Diseases Training Grant!


labGermanyIPNC2012sm.jpg September 2012:  Alison, Louise, Brittany, Jonathan, Asya, and Rick attended the International Pathogenic Neisseria Conference in Würzburg, Germany in September 2013.  Brittany gave a talk and Louise, Jonathan, Asya, and Rick presented posters.  Everyone enjoyed the scientific and social interactions, including the banquet at the Würzburg Residenz.
