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.

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 https://plos.io/44b4vQd
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 E. coli outbreak linked to romaine lettuce ripped across 15 states in November, sickening dozens of people...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."

TWiV 1210: Clinical update with Dr. Daniel Griffin week 17.04.2025
56000 confirmed fired federal workers. More than third of the cuts target health services, aiming to deliberately disrupt disease control and research as well as national and global human health services. #fascism #stopfascism #trump #musk #hostiletakeover
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."

Trodde att man gjorde insulin från grispancreas, tror det var så man började iaf. Så överhörde jag en föreläsning min dotter tittade på. Tydligen kan man mippla m DNAt i ecolibakterier o få dem at producera insulin. Typ så förstod jag det, får läsa på. Men ändå. Magi!
PHORCE allows measurement of lytic #phage amplification rates in bacterial populations. This study uses PHORCE to reveal phenotypic diversity among #Ecoli & #Paeruginosa phages; phage- #antibiotic interactions are mainly determined by the drug @PLOSBiology https://plos.io/3G2myhf
Massive #Haushaltskürzungen und #Personalkürzungen unter der #Trump-Regierung bremsen Tests, Inspektionen und Forschung im Bereich #Lebensmittelsicherheit.
Betroffen sind u. a. Untersuchungen zu #Listerien, #EColi und #Blei in #Kindernahrung.
Expert*innen warnen, dass ohne ausreichende Kontrolle das Risiko gefährlicher #Lebensmittelinfektionen steigt..
The bacterium Escherischia coli has an affinity for microplastic particles (polyethylene, polystyrene, and polypropylene) and forms biofilms that have a higher resistance to multiple antimicrobial compounds than biofilms formed on other substances such as glass. Microplastics may thereby accelerate the growth of, and human exposure to, antimicrobial-resistant pathogens.

These are the 20 most-studied #bacteria — majority ignored
Model microbes such as Escherichia coli hog scientists’ attention, leaving most known bacteria with few publications devoted to them.
Study of over 43,000 bacterial species found #Ecoli dominates with 21% of all publications, followed by human pathogens like #Staphylococcus aureus. Microbes crucial for human health and Earth's ecosystems remain largely unexplored, Univ of Michigan biologist Paul Jensen reported.
