Everything You Need to Know About China’s Child Pneumonia Outbreak
By Bloomberg News
November 24, 2023 at 2:15 AM EST
"China’s health-care system is once again in the spotlight as a wave of pneumonia cases sweeps through the country, hitting kids particularly hard. The sudden increase in sick children, and a report suggesting widespread clusters of undiagnosed respiratory illnesses, prompted the World Health Organization to ask for more details in order to allay concerns that a novel pathogen — something like Covid-19 — was the source of the outbreaks. So far, Chinese officials say, it’s simply a laundry list of known germs that’s causing the problem.
"Doctors have been warning for weeks that a common bacterial infection would likely cause a spike in walking pneumonia”' cases. In response to the WHO’s request for more data, Chinese health authorities said the uptick in outpatient visits and hospitalizations has been due to the spread of mycoplasma pneumoniae, RSV, adenovirus and influenza. Importantly, they say they haven’t detected any new pathogens. In turn, the WHO said that while the level of illness is unusually high for this time of year, it’s not unusual for winter to bring respiratory diseases. The group advised people to take basic precautions to reduce their risk — wear masks, stay home when sick, wash their hands regularly — and said there’s no need for any travel restrictions based on the current situation."

While the main focus has been on structural proteins like Spike, there is very limited structural and functional information on the effects of emerging mutations on other essential non-structural viral proteins
Speaking of neat papers, this was one of the coolest papers I read back in 2021.
It is such a nice piece of microbial chemistry, linking into sustainability and the circular economy, and shown in such a clear way too.
It should be free to read, so enjoy!
💡 So, can we predict phage-bacteria from their genomic data ? Yes, to a certain extent !
There is much more work to be done to improve these predictions, but our study demonstrates feasibility. We anticipate similar approaches could be applied to many bacterial species.
👏 Congrats to the leading authors Baptiste Gaborieau, Hugo Vaysset, and Florian Tesson and to all the great team.

Contamination in Microbiology
Anyone who has worked in a microbiology lab can empathize with the anguish of having a contaminant ruin your experiment. In many cases, such as in clinical laboratories or in the food industry, contaminants can prove devastating and challenging to control. When dealing with environmental samples, on the other hand, contaminants are the norm.

Phages Unleashed: The Heist of CRISPR Repeats
by Sarah Camara-Wilpert and David Mayo-Muñoz
Bacteria, just like humans, are frequently infected by viruses (bacteriophages or phages). Phages replicate at the expense of their hosts, killing them and the process releases hundreds of progeny into the environment to complete their life cycle. The end of bacteria? Not so fast!

The spread of antibiotic-resistant #bacteria is an enormous challenge for the #healthcare system. It is almost impossible to stop the development of #antimicrobial resistance, and there are almost no new kinds of #antibiotics being developed that can be used against drug-resistant bacteria.

Slime moulds usually live as single celled organisms, but will occasionally perform an astonishing feat of cooperation - gathering together as a collective ‘organism’ to form structures such as fruiting bodies. They may resemble fungi, but are really a unique group of amoebozoa.

So consider this a sort of re-#introduction (timed with scicomm.xyz's #upgrade to 4.2.1!) to our #microbiology journal club. We haven't agreed on a final format yet, but we do agree that: we want to keep doing a #livestream, focus on producing more #graphics, have both a deep dive and a news overview, add a more general #review, produce in smaller batches that have a #theme tying shows together, and explore new #platforms.

I hope at least our boosts are helpful in connecting you to cool #microbiology on the #fediverse. We got together last week to check-in and see what we wanted to do about #microbiojc.

Recent reading: THE INVISIBLE SIEGE: THE RISE OF CORONAVIRUSES AND THE SEARCH FOR A CURE, by Dan Werb, is a deep-dive into the basic #science of coronaviruses that occasionally has the pace and urgency of a thriller.
The pivotal figure is Ralph Baric, a professor of microbiology at UNC who's spent his whole career on coronaviruses, which were a scientific backwater before 2003: coronaviruses were interesting, but didn't cause any significant human diseases. (Though the book notes that the 1890s Russian flu and the 11th-century plagues of China's Song dynasty might have been the emergence of those coronavirus strains that are now minor.) (1/3)

Structure, immune system, and circulatory system are elements of an ecosystem. There are other parts.
The roles of #FreeLoaders and #Suckers in an ecosystem play a part in a sustainable ecosystem. I don't want to be a Sucker. I'm way out of date to be able to provide labor. Don't need to #monetize my attention. Trying to figure out how much currency helps enough but doesn't make me a sucker such that if I leave too much of a currency hole is left, weakening the ecosystem. This same analysis has to be happening with those whose major contribution to powering the ecosystem is their uncompensated labor.
#Microbiology research is exploring how microbial ecosystems operate. The language they use includes FreeLoader and Sucker. Nothing derogatory intended. Open to alternative names for agents who take advantage of others' generosity without giving anything in return.
