Is #Twitter doomed?
Here's a Victorian alarm clock which served as a “memento mori,” reminder of death, in the 19th century. It prompted people to think about the shortness of life. This incredible object is now housed at the Science Museum in London.

The data on pandemic control measures (lockdown and masking) being effective against all respiratory diseases is pretty convincing.
⚠️The bacteria most likely to have induced AmpC β-lactamase are Enterobacter cloacae, Klebsiella (Enterobacter) aerogenes, and Citrobacter freundii. DO NOT use ceftriaxone and ceftazidime against these bacteria, even if they test susceptible. Cefepime is OK if MIC ≤2 mcg/mL. If higher, use a carbapenem
Antibiotic resistance due to AmpC β-lactamases may not be apparent when initial resistance testing is done. It may only be provoked by exposure to antibiotics 💊 (induced chromosomal resistance)
Which of the following bacteria is most likely to produce an AmpC beta-lactamase?
