Vibrio Vulnificus

If something can be destroyed by the truth, then let it - be it a person, a government, or an empire built on lies.

Flesh-eating virus kills four in Florida The first fatalities in connection with the bacteria Vibrio vulnificus this year have been recorded.

Antagonism as a foraging strategy in microbial communities In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependen...

Thrilled to share our new paper in @science.org describing our discovery that bacteria can switch from competitors to bonafide predators when resources run dry—arming nanoscale “spears” (T6SS) to stab & consume neighbours.

This story started when we put two Vibrio species commonly found in the coastal oceans under the microscope. V. anguillarum cannot grow on alginate, an algal polysaccharide, but V. cyclitrophicus can. So how does the former species grow? The answer: By killing the ones that can

This Is How I Keep Showing Up A infectious diseases physician’s reflections on trust, defiance, and public health in a time of outrage

Even when we’re cast as villains, those of us working in infectious diseases still have a vital role to play. In this reflection, I share how I’m continuing to show up for patients, for public health, and for the next generation even when it’s hard.

YouTube video by Harvard Medical School The Evolution of Bacteria on a “Mega-Plate” Petri Dish (Kishony Lab)

In 2016, the Kishony Lab at Harvard Medical School put together this demonstration of acquired antibiotic resistance in E. coli bacteria, creating a mega-Petri dish (2' x 4') with a stepped gradient of antibiotic.

Seeing the mutants emerge & spread is an elegant demo of evolutionary change.

Invasive meningococcal disease is one of the scariest diseases, period. People can go from asymptomatic to dying within 24 hours. Even with appropriate care, 1 in 6 will die, and another 1 in 4 will have permanent disability including loss of limbs secondary to meningococcemia-provoked thromboses.

Try some of that with Gulf oysters. It’ll just make me more angry.

Dating Bacteria is hard due to the lack of maxima. Assuming aerobes likely postdated the GOE gave us better resolved ages, but also surprised us, but not Dr Dayhoff, showing O2 use predated its atmospheric rise by 900 Mys and helped oxygenic photosynthesis to evolve. www.science.org/doi/10.1126/...

The Office of the U.S. Trade Rep. (USTR) has confirmed that pharmaceuticals are exempt from BOTH the 10% base rate tariff plus additional reciprocal tariffs. Small ray of hope for biotech (for now).

Assessing toxicity and competitive fitness of Vibrio isolates from coastal waters in Israel | mSphere The ocean’s surface water temperatures have increased in the past decades due to climate change. This increase correlates with the spread of Vibrio, a genus of aquatic bacteria, many of which are pathogens of humans and marine animals. Since Vibrio-...

Our paper on vibrios isolated from Israel's coastal waters is now online in mSphere (now with a working link). We analyzed the pathogenic potential (genome sequences, toxicity, and antibiotic resistance) of 23 new isolates.
