#COVID19 Journal Club: COVID-19: “The environmental implications of shedding SARS-CoV-2 in human faeces”

We’ve posted recently a few times (here, here, and here) about the idea of doing wastewater surveillance for SARS-CoV-2 (and we’ve just submitted a grant on this as well).  In those cases the focus is on detecting RNA from the virus and using that to guide community health decisions such as when to end (or …

Journal Club: “Crewmember microbiome may influence microbial composition of ISS habitable surfaces”

(h/t to Mark Martin for posting about this on Twitter) A break from COVID-19… Microbes in Spaaaaaaaaaace.  (it never gets old).  This article entitled “Crewmember microbiome may influence microbial composition of ISS habitable surfaces” is a much needed addition to the literature on the ISS microbiome.  Work from our lab an others has examined the …

#COVID19 Preprint Journal Club: “Temporal detection and phylogenetic assessment of SARS-CoV-2 in municipal wastewater”

Wastewater detection for SARS-CoV-2 seems to be a hot topic these days (full disclosure, we recently submitted a grant recently to jump on this same bandwagon).   This study “Temporal detection and phylogenetic assessment of SARS-CoV-2 in municipal wastewater” took place in Montana (USA).  This study goes a bit further than the previous one by genome …

#COVID19 Preprint Journal Club “Transmission routes of Covid-19 virus in the Diamond Princess Cruise ship”

Given all the media attention this ship got, I think this is a really interesting article; “Transmission routes of Covid-19 virus in the Diamond Princess Cruise ship“.  The assumption among many folks is that there might have been airborne transmission between staterooms on the ship, considering the number of people that were infected.  This article …

#COVID19 Preprint Journal club: “Considerations for Large Building Water Quality after Extended Stagnation”

This one falls in the category of “yet another problematic thing to think about”.  In this article “Considerations for Large Building Water Quality after Extended Stagnation” the authors are not talking about COVID19 per se.  They are discussing the hazards associated with stagnant water after building remain closed for a long time because of the …

New preprint of interest on SARS-CoV-2 Aerosol and surface stability #COVID19 #Coronavirus 

There is a new preprint of interest to those interested in SARS-CoV-2, the novel coronavirus spreading around the world. Details: Aerosol and surface stability of HCoV-19 (SARS-CoV-2) compared to SARS-CoV-1 Neeltje van Doremalen, Trenton Bushmaker, Dylan Morris, Myndi Holbrook, Amandine Gamble, Brandi Williamson, Azaibi Tamin, Jennifer Harcourt, Natalie Thornburg, Susan Gerber, Jamie Lloyd-Smith, Emmie de …

Story behind the paper: RtxA type 1 secretion system and other virulence factors in Legionella

So this work is a spinoff of a big project that we were involved in (but almost all of the work was done by Amy Pruden’s lab at Virginia Tech).  In the larger project, they examined the genomes of over 100 clinical isolates of Legionella pneumophila, as well as 10 clinical isolates from patients during …

#COVID19 modes of transmission and fomites (Twitter comments)

I have been trying to collect information about the new coronavirus and transmission via fomites (objects or materials such as door handles, clothing, phones, etc).  Yesterday I posted to Twitter asking for input and got a large collection of useful responses. See these two tweets and the responses to them.  I highlight some key responses …

Report on 2020 Spacecraft-Associated Genome Analysis (SAGAn) workshop at NASA JPL

So this last week, we ran a workshop on bacterial genomics at the Jet Propulsion Laboratory (JPL).  Who is “we”?  An amazing collaboration across several institutions.  The whole thing was initiated by Dr. Parag Vaishampayan (NASA-JPL), who contacted myself (UC Davis), Dr. Elinne Becket (Cal State San Marcos), and Dr. Kenisha Johnson (Alabama A&M) about …
