Story Behind the Paper: Draft genomes from JPL spacecraft… assembled by undergraduates

Just a quick post here that our paper just came out, “Draft Genome Sequences of Bacillus glennii V44-8, Bacillus saganii V47-23a, Bacillus sp. Strain V59.32b, Bacillus sp. Strain MER_TA_151, and Paenibacillus sp. Strain MER_111, Isolated from Cleanrooms Where the Viking and Mars Exploration Rover Spacecraft Were Assembled“.  This describes the genomes of a couple new …

#COVID19 Preprint Journal Club: “Detection and Survival of SARS-coronavirus in Human Stool, Urine, Wastewater and Sludge”

(h/t to Heather Bischel for the link) Yet another really nice and comprehensive review of the state of things regarding wastewater sampling for SARS-CoV-2.  “Detection and Survival of SARS-coronavirus in Human Stool, Urine, Wastewater and Sludge“.  This paper does a particularly nice job of looking at the following three questions: 1)What is the evidence for …

#COVID19 Journal Club: “Wastewater-Based Epidemiology: Global Collaborative to Maximize Contributions in the Fight Against COVID-19”

This is less of an article than an announcement of a global collaboration and website for wastewater sampling for SARS-CoV-2.  “Wastewater-Based Epidemiology: Global Collaborative to Maximize Contributions in the Fight Against COVID-19“.  This is a non peer-reviewed opinion piece that summarizes the current state of knowledge on wastewater testing for SARS-CoV-2 and describes their COVID-19 …

Journal Club: “Initial Mapping of the New York City Wastewater Virome”

While not about COVID19 directly, this paper “Initial Mapping of the New York City Wastewater Virome” has implications for the many many folks looking at SARS-CoV-2 in wastewater these days.  This work is looking at all the viruses in the wastewater system and is one of relatively few metagenomic studies out there that focuses on …

#COVID19 Journal Club: “Collection of SARS-CoV-2 Virus from the Air of a Clinic within a University Student Health Care Center and Analyses of the Viral Genomic Sequence”

  This article (“Collection of SARS-CoV-2 Virus from the Air of a Clinic within a University Student Health Care Center and Analyses of the Viral Genomic Sequence”) caught my attention initially because of the air sampling aspect, but upon reading the Abstract I was struck by something else.  Here they did air sampling in a …

#COVID19 Preprint Journal Club: “How can airborne transmission of COVID-19 indoors be minimised?”

This is a must-read article for folks thinking about mitigating the risk of COVID-19 indoors.  A venerable author list, including many experts on all aspects of indoor ventilation, pathogen transmission, aerosol science, etc.  Since it is a review, it’s hard to summarize.  Basically they argue that the current status of the science on indoor microbiology …

#COVID19 Journal Club: “SARS-CoV-2 RNA concentrations in primary municipal sewage sludge as a leading indicator of COVID-19 outbreak dynamics”

Yet another wastewater surveillance study for SARS-CoV-2.  Seems to be the hot topic these days.  This is a great paper by Jordan Peccia and colleagues.  They collected wastewater samples over the course of a couple months and saw how well those correlated with testing data and hospital admissions.  Not only were the correlations extremely high, …

We can model microbial growth in carpet dust after short bursts of elevated moisture

We are pleased to announce the publication of our manuscript titled “Modeling microbial growth in carpet dust exposed to diurnal variations in relative humidity using the “Time-of-Wetness” framework”  in the journal Indoor Air. This work is a culmination of research investigating how changes in relative humidity impact microbial growth in carpet dust. Our related study …

Coronavirus Environmental Testing Service #COVID19

So our collaborators from the Biology of the Built Environment (BioBE) Center at the University of Oregon have been working hard to get their environmental sampling qRT-PCR assays for SARS-CoV-2 up and running.  I’m sure we’ll be posting more about their results as they develop. But they are now offering their testing as a service …

#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 …
