Is it time to start growing our own food?

See how the #trump administration is mishandling food safety.

E. coli outbreak sickened more than 80 people, but details didn’t surface

It with great pleasure that I present a new paper published in the ISME Journal!

In this study, we identified a trade-off between Escherichia coli’s ability to colonize new hosts and to reside within them. This trade-off, together with niche differentiation between main lineages, may explain their long-term coexistence and shape their evolution.

Nanoplastics may be turning E. coli into a stealthier, deadlier pathogen. What does this mean for our food supply?

A dangerous #Ecoli strain has emerged; a small #mutation may explain its rise
A sweeping genetic analysis by researchers at #CDC suggests a tiny mutation in one of the #bacteria's molecular weapons may be behind the strain's rise. The mutation the CDC researchers found was in one of these #T3SS effectors, a protein called #EspW. The CDC researchers suggest this could help E. coli when it's on #lettuce and other #produce.

Tech insights on a dangerous E. coli: A tiny mutation in its EspW protein, a 'molecular syringe' part, might be key to its recent spread. CDC study shows this genetic tweak could help it better invade leafy greens. Smart but scary bacteria.

Why are young adults getting colorectal cancer? E. coli may be a clue
Exposure to a bacterial toxin in childhood may be playing a key role in the global rise of early onset of colorectal cancer, according to a new study.

“A stool sample, he explains, would contain DNA from colon tissue to help medical providers see evidence of mutations—the more mutations, the higher someone’s risk of colorectal cancer. Once you know someone is at high risk, you can take greater steps to monitor and catch the cancer early.” #dna #epigenetics #isogg #coloncancer #ecoli #colorectalcancer

Long-range #genome interactions in #bacteria. In #Ecoli, 6 out of 7 rRNA #operons cluster by an unknown mechanism. This study shows that high expression of sigma factors σH or FecI, localized in the inner membrane, disrupts clustering, an effect suppressed by σD @PLOSBiology plos.io/44b4vQd

Top left: Scheme for rrn operon tagging. Two different par sites (parSpMT and parSP1) were placed upstream of rrnA and rrnD, respectively, in the parent strain MG1,655. These sites were visualized by co-expression of their cognate fluorescent ParB proteins (pMT1 GFP-ParB and P1 CFP-ParB). Top middle: Violin plots of the distance between rrnA-rrnD under indicated stress conditions. Top right: A representative image of rrnA-rrnD foci without added stress (top panel) and de-clustering with heat stress (bottom panel). Bottom: Model for σD-mediated rrn clustering. σD-bound RNAP (dark green) is responsible for clustering rrns (blue circles) at the membrane either directly or through other unknown factor(s) (gray hexagon). GroEL/ES (red oval) represses the activity of σH (orange) preventing it from competing with σD for core RNAP. σH is typically localized to the inner membrane and degraded. Upon heat stress, σH levels rise, and GroEL/ES, being diverted to un-folded substrates (pink oval), is unable to repress σH activity.

Synchronised electrical waves in #Ecoli biofilms might be part of their survival toolkit, but a few unanswered questions about the experimental approach mean the evidence is ‘incomplete’. Could this be a conserved mechanism across biofilms? #Microbiology

"An internal report obtained by NBC News revealed that the agency did not name the produce company involved in the outbreak and they did not share information with the public about it."

"A deadly E. coli outbreak linked to romaine lettuce ripped through 15 states at the end of last year, but the Food and Drug Administration didn’t publicly disclose it, according to a report.

The outbreak was linked to the death of one person and hospitalized 36 people in November, including a 9-year-old boy who nearly died of kidney failure."

So, this probably explains why the @fdarecall_bot stopped working... #FoodSafety just flew out the window!!! Thanks #Trump & #DOGE! Keeping us safe...NOT!

A deadly #EColi outbreak hit 15 states, but the #FDA chose not to publicize it

The outbreak linked to #RomaineLettuce killed one person and sickened at least 88 more, including a 9-year-old boy who nearly died of kidney failure.

"An E. coli outbreak linked to romaine lettuce ripped across 15 states in November, sickening dozens of people, including a 9-year-old boy in Indiana who nearly died of kidney failure and a 57-year-old Missouri woman who fell ill after attending a funeral lunch. One person died.

"But chances are you haven’t heard about it.

"The Food and Drug Administration indicated in February that it had closed the investigation without publicly detailing what had happened — or which companies were responsible for growing and processing the contaminated #lettuce."
